---------------------------------------------------------------------- Date: Mon, 26 Apr 1999 22:23:29 -0400 (EDT) From: pbabcock <pbabcock at mail.oeonline.com> Subject: More on BS survival (From Kiplinger...) Greetings, Beerlings! Take me to your lager... Sorry to turn over some composting mash offal, but, almost on the heels of our discussion regarding the state of home brewing - in particular, the survival of brew shops - the Kiplinger Washington Letter (Great little weekly news summary, for those who don't read it) echoes many of the points we made, though addressing the broader subject of all retail business. To wit, they say "Providing good customer service is key to a healthy bottom line. (Listen up, oh ye who think your customers owe you!) They offer the following pointers (some of this oughta sound familiar): o LISTEN To CUSTOMERS! o Ask for feedback. (Be sure to reread the line above.) o Beef up service and repair department (this doesn't apply directly to our discussion, but could be construed as hiring those WHO KNOW WHAT THEY'RE DOING as opposed to the lowest cost, off the street clerks. A HB shop's "service department can be construed as those who give advice on the actual brewing, selection of goods, etc.) o Make it personal - the EDGE against those low-cost, out-of- the-locale suppliers: get to know your customers, treat them like a friend (for those who don't know: that means with courtesy, and respect with a hint of familiarity) and they'll come back. o Play an active role in the community. This can be done, by the way, without huge outlay of cash. Simply keeping their grounds attractively and "lobbying" that surrounding shops should do the same pushed a local small drug store to the fore in Garden City and Belleville, Michigan back in my college day. To the point that he did admirably well against the MAJOR drug chains in the area. Rest his soul, he had the concept down pat! (And a boss worthy of note. Taught me a lot, and treated me fairly and with respect - as he did his customers.) o Put PEOPLE WHO LIKE PEOPLE in the frontline jobs. Oscar the Grouch is really only good at selling lunchboxes and children's toys... o Empower employees to help. This doesn't mean you should allow them to give away the shop, but an employee should have the power to make right things that went wrong within the shop's realm of control. "I'll give you $$$/Free if I can't beat your best deal" is the gimmicky pinacle of this approach, but there are others. Acts as simple as replacing the <item> that crashed to the ground as the customer was trying to put them into the car can cement a relationship at little cost. Free yeast if the batch we gave you the recipe for doesn't turn out. Doesn't have to be to every- one all the time either, but careful about feeding someone's persecution complex (Gee, they've done that for X, but not for me...) o Reward those who make service a priority (Duh!) o Use technology wisely. This one they actually don't say nearly enough about. One of the greatest turn-offs in this digital, internet age is to go to a site to buy something or get information on something you wish to buy to find a worthless billboard-type web site or one that hasn't been updated in a dog's age. Having a web site simply to have one can cost you more business than it creates (Glad I'm not selling anything for how out of date my sites are...). o Cut customers slack when they need it. This kind of goes hand-in- hand with the empowered employee bit, but can be more, too. Let the known customer skate with a promise to pay it later when they come up a bit short at the counter, for instance. Makes it personal, shows you trust and respect them - that you've noticed their support of your business. o Help customers cut their costs. Use the original issue in this series to your advantage: help arrange a bulk grain buy. At cost. Why? You enamor those you are helping, help your situation or standing with your vendor through increased volume, and, perhaps, lower your own costs by hitchhiking your order on top of their's. You all win. And guess whom they're most likely to patronize when their grain bins run empty and the group isn't ready for another bulk purchase. Uh-huh! o Manage inventories. This is important. Though Kiplinger's approaches it more from the manufacturing/mass merchandising aspect, it holds true for HB shops as well. Having a huge investment in inventory can strangle you faster than kudzu after a hop bine. Yes, it's good to have a large SELECTION, and enough inventory to keep a moderate order cycle vs demand, but watch what moves closely and order appropriately. Be careful to check for customer appeal before bringing in that latest gadget or supply (see the first two items in this list for a hint on just how to accomplish that little trick.) Anyway, sorry to go on about this, but it concerns me. It was interesting to see this piece in the Kiplinger Washington Letter so close on the heels of our discussion. Kind of lent credence to it. On another note, I was happy to see a bit of expansion in our area recently with the opening of a new shop in Dearborn (Heights?) and an inquiry from a beer/wine shop in Warren regarding carrying homebrewing supplies. This on the heels of one closing (which was personally a bit painful. They were right on the way home from work.) See ya!

In HBD #3014, Joy Hansen writes: "You might agree that Star san is appropriate as a sanitizer for my situation. I must live with the foaming, the cloudy solutions, and check the ph frequently. OTOH, Star San solutions might have an indefinite storage period and could be used over and over until the pH changes?" Have you tried a product called Oxine. It is a chlorine dioxide solution. Works very well for me the past year or so. I remember a small article about it in BT some time ago.

Date: Mon, 26 Apr 1999 22:20:53 EDT From: ALANDOWDY at aol.com Subject: Dwarf Hops A recent article in Zymurgy and a few posts here about buying hop rhizomes got me thinking again about how unsuccessful I was finding a source for any of the dwarf species here in the US. All the information I was able to find referred to commercial field tests in the UK. I realize it's probably too late in the season but has anyone seen any dwarf hop rhizomes for sale here in the states? Thanks. Alan Dowdy Torrance, CA Return to table of contents
Date: Tue, 27 Apr 1999 00:52:38 -0500 From: "Rob Moline" <brewer at isunet.net> Subject: The Jethro Gump Report The Jethro Gump Report Nitrogen Heads As far as I am concerned, the nitrogen is in solution....And agreeing that it is 'nearly insoluble,' I have been forced in the past to "nitrogenate' my stouts at LABCO at a much higher pressure than I would normally used for carbonation. In fact, Matt Brynildson, (excuse me Sir, if I spelled it wrong) of Goose Island in Chicago has done research on this, and spoken at MBAA Tech Conferences on his work, which involves instrumentation to measure dissolved N2, and dissolved CO2, in his products.... Incidentally, among his most interesting findings was the fact that, as measured by Siebel, there was a 10% decrease in IBU's after N2! But don't ask me, Al...visit a local brewer (to your area) ...... My understanding on this matter is that Guinness itself was the major developer of the N2 phenomenon, decades ago.... .. as they were in search of a process that would approximate the cask beer/handpump effect, yet allow them the control from headquarters that was gained by having a standardized product, with CO2/N2, in the keg from the brewery.... Delivered via CO2/N2 gas to maintain equilibrium of gases in the keg, and to provide the propulsion to force the brew through the restriction of the 'sparkler/breakout' plate that can be seen in every 'Guinness' faucet, they seem to not only have delivered a successful product, but also a strategy that has been adopted elsewhere.... This would provide uniformity in serving, and deliver less waste, as a similar cask beer might not last a week in a slow sales period. Whereas a nitrogen fitted keg is good for a longer period..... If one looks at the Draught Flow cans that serve Guinness, Boddington's and others, one finds the patented 'process/technique' of widgets, drilled with a laser accurate hole of 0.6 mm, fitted into the 'tin.' After the brew is filled into the tin, and before the crown is attached, a dose of liquid nitrogen is dropped in.....after the heat of pasteurization...this N2 helps 'push' the brew and gases into the widget...... When the tin is opened.....the effect is obvious..... I'd be hard pressed to change my views....I understand that my use of very cold temps...and higher than normal pressures, does in fact allow me to saturate a brew with nitrogen...... And Adam..."silent bob" <holdenmcneil at hotmail.com> seems to hit the nail on the head with what I thought was an extension of the obvious contents of the bubble wall theory... Yes, the contents of the brew do dictate many of the properties that aid head retention....but the fact that nitrogen might fill those bubbles, and that this space is somewhat equivalent to the content of atmospheric air....lends further credence to the concept of reduced bubble coalescence, secondary to similar gasses on both sides of the wall.... An excellent question for the Siebel staff, yes? MR JOY....... Jethro wishes to apologize for any incorrect reference to Ms. Hansen....it was never my understanding that she was a he....though whether she is a he...or he is a she...or he is using her account....or she is...?? OH, well lets call you Happy Hansen!! All I can say is that I must have been sober at the time......! BWRT....your experiences regarding iodophor and precipitates, I am very sympathetic...for I have experienced these myself....past readers over the years would have seen this.... But, I disagree that the possession of a commercial CIP would make a difference to the precipitate....I have often observed it before CIP....It's the water, yeah? With, again, all respects to Mr. Fix, I would suggest that you contact Charles Talley of 5 Star directly with your hopes that <<"OTOH,Star San solutions might have an indefinite storage period and could be used over and over until the pH changes?">> Mr. Talley is the Chief Chemist for 5 Star, is easily approachable, and as the designer of the stuff, I would suggest he be a reputable advisor in addition to Mr. Fix. His address can be found within the 5 Star website, I am sure....... BTW, 10/60 is 10 minutes.......(2/24 is 2 hours....4/7 is 4 days.....2/12 is 2 months...etc...yes?) Dr. Pivo.... He's Right........ Though he shot a few too many......Just my 2 cents..... And While We Are On The Subject!!!!! George DePiro....that ....that....that.......%^$ at ((*^%%... I am pleased to announce that George is about to....no, it has been coming for some time....convert from amateur to professional brewing...as the Head Brewer for a concern in Albany, New York...the Evan's Brewing Company....a re-birth of a family legacy...commercially to be known as the Albany Pump Station.......opening date yet to be announced..... Take it from me....there's medals up there in Albany.... Good brewing, George! WOI Radio Brewing Show... Screwed up again....the show is on Thursday......2.29.99....640 AM, 10:00-11:00 am CST.... Phoenix...... See ya there! I will be part of the Toast from Phoenix......Sorry, I can't carry a carboy back on the aircraft! Anheuser Busch.... Being a major employer in Littleton, Colorado...and whether or not there are brewers/employees directly affected.....(How could you not be) and especially if there are....

I have baked my bottles for over two years at 350-375 for an hour and a half and let them cool overnight in the oven without disturbing them.

Date: Tue, 27 Apr 1999 08:10:35 -0500 From: David Whitman <dwhitman at rohmhaas.com> Subject: beer stone, acids and stainless steel Dr. Pivo has his phenomenology correct, but his chemistry leaves something to be desired: >Beer stone is just the little hard dry deposits that are left behind >from any aspect of the beer making... >... >Beer stone is divided into "inorganics" (principally carbonates... the >same stuff as the white fuzz on your faucet if you have high carbonate >water) Beer stone is the phrase used to describe deposits of calcium oxalate resulting from brewing, not carbonates. However, they can be removed with acids as Dr. Pivo suggests. I see essentially no fizzing when removing beer stone with acid, which one would expect if it was a carbonate. Not just any acid will do; to remove calcium oxalate you want to choose an acid whose anion forms a soluble calcium salt. (HCl, acetic and nitric are OK, but sulfuric and phosphate won't work). I think the technical term for the ORGANIC residue from brewing is "gunk", not beer stone. >Since most industrial stuff is made of stainless, the acid of choice is >often "Nitric acid" since it is what is called a "reducing acid" , and >"pickles" the stainless, giving it a corrosion resistant surface. > Nitric is an OXIDIZING acid. Mixing it with other cleaning agents under the assumption that it was a reducing agent could lead to some extremely dangerous mixtures. But Dr. Pivo is correct that nitric acid will help maintain the corrosion resistant surface of stainless steel (by oxidizing the metal to produce a passivating oxide layer).

Date: Tue, 27 Apr 1999 08:37:32 -0400 From: Alan McKay <amckay at ottawa.com> Subject: HELP : my water really sucks! Hi folks, Firstly, if you are reading this in r.c.b then please copy replies to my email amckay at ottawa.com since I'm still very much in moving mode, and may not have much time to be checking the newsgroup. HBD folks don't bother, since I can come back and check that any time on the web page. As you all know, I moved last weekend. But my water in my new place is horrible! It tastes rusty. There is a water softener there, and I bought salts and put them in, but there is no difference yet. Maybe the thing isn't turned on or something, I don't know. Or maybe it's set to only go off once a week or something. I'll have to dig into the manual and see what's what. I know I have to get the water tested to see exactly what's going on, but aside from that what else can I do? I'm considering getting a water distiller or something. Anyone know if that's possible, and how much it costs? Like one of those machines that produce the bottled water you buy in drug stores.

Date: Tue, 27 Apr 1999 09:01:09 -0400 From: "Nix, Andrew" <anix at bechtel.com> Subject: Re: Cooling Wort <Snip from Dan's Post> >From a thermodynamic point of view this is very inefficient. They are starting out with a small thermal mass ( say 2.5 gallons) with a high temperature differential in a conductive vessel. By pouring it into cold water, they now have to cool a large thermal mass, with a low temperature differential ( about 110 F) in an less conductive vessel. This operation can take 5 hours. <SNIP> Dan, what do you mean by high temperature differential?? Differential from the pitching temperature??? As for the thermodynamics, mixing is a direct contact process...heat transfer and equilibration to the mixed temperature in the presence of some mixing is nearly instantaneous. The point here is that you need the enthalpy of each fluid. The formula here is: m1*h1+m2h2 = m3h3 where m is the mass of the fluid and h is the enthalpy of the fluid. For simplicity, we can assume the wort to be liquid water, so the enthalpy of say 200F water (cools from boiling to 200F very quickly by natural convection) is 168.09 Btu/lb with a specific volume of 0.12445 gal/lb....if we put the cold water in the freezer and let it get to nearly freezing, let's say 35F, the enthalpy is 3.0460 Btu/lb and the specific volume is 0.11983 gal/lb. So...if we mix 3 gals of water at 35F with 2 gals of wort at 200F, we should get: 3 gal cold water/0.11983 Gal/lb = 25.035 lb cold water and 2 gal hot wort/0.12445 gal/lb = 16.071 lb hot wort 25.035 lb*3.046 Btu/lb + 16.071 lb*168.09 Btu/lb = (25.035 lb+16.071 lb)*h3......solving for h3 we get....67.572 Btu/lb which is a mixed temperature of 99.5F. This is just an example, but this is the way you would do it. However, the assumption here is that the specific heat (basically enthalpy/unit temp) is equal to that of water. Data may be available on the ratio of specific heat of wort vs. water at certain temperatures. You could use this type of analysis to determine how much cold water to add to a set volume of nearly boiling wort to equilibrate at a desired temp, but iterating will be necessary. The values for enthalpy and specific volume at different temps (and atmospheric pressure) can be found in engineering tables for compressed water on the web somewhere. I have a shareware program here if anyone is interested. Andrew C. Nix Frederick, MD Return to table of contents

I am getting thirsty >thinkin about this...;-) And Jeff Renner <nerenner at umich.edu> responded: >It means a light, usually pale, thirst quenching beer that hits the spot >on a hot summer afternoon (I suppose summer is about a week long up where >you are) when you've been mowing the lawn. Something that also wouln't >endanger your safety operating machinery. A standard commercial North >American lager would be an example of this... That's certainly the standard definition. Personally, my definition of lawnmower beer can be stated in one word: Barleywine! Here's the rationale. When doing yard work on a hot summer day, it's fairly easy to get a little hot and thirsty. Alcohol is not a good thing to use to rehydrate your body. For that, water (or even better, fresh lemonade) does a great job. Quenches the thirst and rehydrates the body. Drink it during and immediately after mowing that lawn. Then, late in the afternoon when all the yard work is done and the lawnmower (I swear by the good ol' dependable human-powered variety; even the sound of one is relaxing, a nice contrast to the power-driven snarl that's all too common today) is resting comfortably in the garage, nothing hits the spot better than a homebrewed barleywine, sipped while relaxing and viewing the fruits of your suburban labor. - -- Joel Plutchak <plutchak at uiuc.edu> Drinking lawnmower barleywine in East-central Illinois Return to table of contents

Kuzara) baked his bottles to sanitize and some broke and asked: >has anyone been successful >sanitizing in the oven and what is wrong with my procedure or what is the >suggested oven procedure? I don't do it as much as i did years ago because I keg nearly everything, but I did do it with success. The key is to anneal the bottles by slowly cooling to avoid differential stress in them. This is easy for me since I have a 28"x36" stone hearth electric pizza oven with 6" insulation. I lay the bottles on their sides several high (like cordwood) and heat it to 225F or so, then leave it overnight to cool. In a regular home oven, you may need to gradually reduce the heat over several hours. Jeff -=-=-=-=- Jeff Renner in Ann Arbor, Michigan USA, c/o nerenner at umich.edu "One never knows, do one?"

Date: Tue, 27 Apr 1999 10:35:11 EDT From: Jebbly at aol.com Subject: (no subject) I am looking for some details on Irish Red Ales. I have not found much information on this "style" and wonder if it is, in fact, an official style of ale. I want to know the characteristics and guidelines for brewing as well as some recipes (all grain) that will point me in the right direction. My only examples are Greg Noonan's Burley Irish Ale (VT Pub and Brewery), Trout River's Red Ale or Boulevard's Irish Ale. Although they seem to be milder than pale ales and esb's I find them better than most english mild ales. They don't seem to have the low alcohol level of milds or ordinary bitters either. Does anyone have any personal knowledge on them or know a good reference I can refer to? Also, I posted a question several months ago but got no response so I'll try again with this one: I am thinking of putting together a rims but have a major concern. How does one keep the temperature constant? Right now I put my mash tun in an insulated box I built and can keep the temp constant for 90 minutes (+ or - 1 degree) which I think is pretty good. My initial feeling is that, with no insulation and only a burner to maintain the heat, the temperatures can flux greatly. What gives? Is there some great trick to this, is it easy or is there an art than needs mastering here? Thanks in advance Dave Grommons Jebbly at aol.com Return to table of contents
Date: Tue, 27 Apr 1999 10:36:21 -0500 From: "Brian J. Paszkiet" <bpaszkie at ux1.cso.uiuc.edu> Subject: 5th Annual Boneyard Brew-Off The Boneyard Union of Zymurgical Zealots of Champaign, IL would like to announce our upcoming 5th Annual Boneyard Brew-Off taking place June 11-12, 1999. We will be judging all 1998 BJCP beer, mead, and cider categories. This is an AHA sanctioned competition as well as a qualifying event for the Masters Championship of Amateur Brewing (MCAB) II (see http://www.hbd.org/mcab for more details). Points will also be awarded for Midwest Homebrewer of the Year. The main judging will start at 9:00 am on Saturday, June 12th. Standard AHA rules apply: we will need three unmarked 10-16 oz brown or green bottles, with bottle ID forms attached to each bottle with a rubber band, a completed entry/recipe form, and $6 for each of the first entry, $5 for each subsequent entry from the same brewer(s). Entries must arrive between MAY 26 and JUNE 5, 1999. We will accept walk-in entries from judges at 8:15 am on the day of the competition (June 12th) as long as the completed paperwork and fee arrive by June 5th. Our special category again this year will be the "No One Gets Out Alive High-Gravity Brew-Off". In this category, we will judge any beer with a starting gravity over 1.070 purely on the basis of drinkability and octane. For this category, we only require two unmarked 6-16 oz brown or green bottles.

I have used 1275 quite a bit, in fact it is my favorite yeast for English bitters. Recently I tried using 1275 on an Imperial Stout, OG 1.110. It was a 3 gal batch and I used the yeast cake(Thames) from a 5 gal batch of brown ale. It took off like a rocket! However, after 3 weeks in the primary, and a week of no airlock activity, I checked the gravity, the yeast pooped out around 1.060. I tried rousing the yeast by gently swirling the carboy, 3 times a day for 5 days, but this was not successful. Since I pitched such an immense yeast cake and aireated the wort, and it still pooped out, I came to the conclusion that this yeast is just not alcohol tolerant enough for high OG worts.

Date: Tue, 27 Apr 1999 12:43:57 EDT From: GregN124 at aol.com Subject: Re: Sanitizing Beer Bottles (Greg Newinski) I sanitize my bottles in the oven. I fill the oven with the bottles, place a jelly roll pan on top of the element and put some boiling water in the pan. Heat oven at 180 - 200 for an hour or so. This builds a lot of steam which sanitizes the bottles better than dry heat. Then after they have cooled I remove the bottles and set a sanitzed cap on each one right away. You must allow them to cool slowly. I started doing this when I felt my dishwasher wasn't getting hot enough anymore. Haven't had any problems so far. Greg Newinski Return to table of contents
Date: Tue, 27 Apr 1999 09:44:18 +0000 From: Joy Hansen <happyhansen at scronline.com> Subject: Non-Returnable Bottes and Ramblings Richard recently wrote about non-returnable bottle damage from oven sanitizing. I'd also like to know more about the composition of non-returnable bottles. Anyone got any thoughts on their composition? Is it possible that the structure of the non-returnable bottle is damaged during the heating process. Are heat sanitized non-returnable bottles that don't break immediately likely too fail when the brew pressure builds up or they receive a small bump? In the mid-sixties, when I was washing glass beer bottles, frequently, the complete bottom of the bottle would separate and give me a nasty hot shower. This was the type of wash tube that extended to the bottom of most bottles and the valve was in the bitter-end of the tube. For some reason, it still seems like a more efficient bottle washing wand because it doesn't remix the old dregs with the comings. Are there HBD readers still using a bottle washing tube that extends to the bottom of the bottle? If so, I'd appreciate knowing where and if it can be purchased. My present bottle washing technique isn't accepted by most home brewers. When I pour a brew (bottle conditioned), I rinse the bottle and let it drain. Then I put the bottle on the bottom shelf of the dish washer and let it go through the complete cycle with sani-dry. No breakage at this point. Before reuse, I rinse the bottles with the newer shorty bottle washer, and immediately thereafter rinse with Star San. I leave the bottles on the bottle rack tower for 15 to 20 minutes. I soak my caps in Star San for about 5 minutes and remove the caps from the sanitizer and leave them inverted on a paper towel. I fill the bottles via a standard brass filling tube and place a cap on each bottle as it is filled. I like beer foam to fill the air space. Many times there's enough CO2 in the brew to accomplish this. I'm not really concerned about the "Monica effect" blessing my bottled brew and the lack thereof might be the dishwasher surficants. Don't know for sure. Now, why was it that I started kegging my brews . . . Ciao, Joy"T"Brew Return to table of contents
Date: Tue, 27 Apr 1999 17:00:29 -0500 From: John.Wilkinson at aud.alcatel.com (John Wilkinson) Subject: lagering I have read in HBD of slowly lowering the temp of the beer after a diacetyl rest. Why? The only reason I can think of for not crash cooling is to prevent shocking the yeast and dropping it out. But isn't it done at this point anyway?

Date: Mon, 26 Apr 1999 16:58:01 -0500 From: Spencer Tomb <astomb at ksu.edu> Subject: Lawnmower Beer/ Try Ginger Jeff: Thanks for the suggestions on making a thirst quenching brew. I have made two batches of a similar light gravity beer to the one you posted except that I added lemon peel and grated fresh ginger root 1/4 cup and 1/2as I cooled the wort. I covered the pot and put it in an ice bath. I returned the condensate on the cover to the pot. I do not have the final gravity at hand but I think it was less than 1.042. I used a Cooper's extract and re pitched a Nottingham yeast from our brewpub. The results were very refreshing. The second batch was better and did not last 5 weeks from the brew date! In the first batch, I made the mistake of getting some of the white part of the lemon peel and that gave a bitter taste. I would like to know others experience with Ginger Beers.

Date: Wed, 28 Apr 1999 00:49:50 +0000 From: AJ <ajdel at mindspring.com> Subject: Lime/Oxalate/Czech Pils Sulfur A couple of people have requested that I post details of decarbonation by lime treatment. To do this it is best that you know the temporary hardness of your water which means that you must know its hardness and alkalinity. If the hardness is greater than the alkalinity the temporary hardness is equal to the alkalinity. If the alkalinity is greater than the hardness, the temporary hardness is equal to the hardness. Nominally, you will be able to remove all but about 50 ppm as CaCO3 of alkalinity. More can be removed by adding supplemental calcium. To know whether your treatment has been effective you need to know post treatment alkalinity (and preferrably hardness as well). Thus I believe you need to obtain test kits for these two parameters. Such kits come from a number of manufacturers, are fairly inexpensive and are not difficult to use. The success of the method requires that pH be monitored so suitable test strips will be needed. The reaction being exploited is: Ca++ + Ca(OH)2 + 2HCO3- --> 2CaCO3 + 2H2O Here's the procedure: 1. Add 1 tsp of chalk for each 5 gal of water being treated and stir. This serves to provide nucleation sites for the chalk (CaCO3) that will be precipitated. 2. Multiply the temporary hardness of the water (in ppm as CaCO3) by 0.74 and then by the number of liters of water (3.78 liters to the gallon) to be treated to get the approximate number of grams of lime required. 3. Increase the result from Step 2 by 20%, place that amount of lime in a beaker or other container with enough water to make a slurry. If the temporary hardness is not known, make a slurry of a couple of teaspoons of lime in water and go by the pH values given below. 4. Add the slurry to the water in increments, stirring and checcking the pH after each addition. Use larger additions at first, then smaller ones. Shoot for a pH between 9.5 and 10 and try to get there fairly quicky. 5. After reaching the target pH range continue to stir and monitor pH. It will drop as chalk precipitates. Continue to add small amounts of slurry to keep the pH in the 9.7 - 10 region. 6. After all the chalk has dropped, the pH will continue to fall as CO2 from the air dissolves but the rate will be much slower. This is your signal to stop adding slurry. 7. Let the water sit for a while to let the chalk settle. During this time CO2 will continue to dissolve bringing the pH down. Don't wait too long or the precipitate will begin to dissolve again. pH 9.6 or so is a good value at which to decant the water from over the precipitate. 8. Measure hardness and alkalinity to see how you did. To increase the effectiveness of decarbonation add as much of a calcium salt as you think you can stand before proceding as above. As a guideline, 2 millimoles per liter of your favorite calcium salt amounts to an addition of 200 ppm as CaCO3 calcium hardness. This will be in addition to the hardness already in the water. Remember that hardness is generally good and alkalinity generally bad for brewing though there are always exceptions. Given this, one of the advantages of this trick is that it compensates for the calcium lost in getting rid of the alkalinity. After treatment the amount of hardness will be approximately the sum of the original and added hardnesses minus the original alkalinity. Alkalinity can be gotten down to the 20's by this method. "Split Treatment": Some of you may be familiar with the so called split treatment used to remove excessive magnesium with lime. I have modified this scheme to make it more effective at magnesium removal. In the conventional implementation 2/3 of the water is treated with lime to the point where the pH reaches 12. This causes magnesium hydroxde gel to precipitate. The clear water is decanted and the remaining third of the volume added to neutralize the excess hydroxide by means of the bicarbonate ions in it. Obviously only 2/3 of the magnesium ions are attacked. My modified "split" treatment doesn't split and attacks the magnesium in the entire volume: 1. Procede as in the procedure above but continue to add lime until pH 12 is reached. 2. After insuring that the pH is stable at 12 let the Mg(OH)2 and CaCO3 settle. 3. When the water clears, decant to another vessel. 4. Add some chalk to serve as nucleation sites. Stir to allow additional CaCO3 to precipitate. 5.While stirring aerate (as with an aquarium bubbler). Continue aeration until pH falls back to pH 9.6. You are using the world's huge supply of free acid - the air. 6. Allow to stand while precipitate settles and then decant. The best source for lime for this purpose is "pickling lime" used to adjust the pH of some types of pickles. It is found at stores that sell canning supplies and is most likely to be found during the fall canning season. If you contemplate using quick lime, be sure you know how to handle and store it safely. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * A couple of questions on Dr Pivo's post. I've always understood beerstone to be calcium oxalate (in fact one of the reasons for wanting to replace calcium lost through decarbonation is to make sure that there is plenty available through to the fermenter to precipitate oxalate thus preventing oxalate haze). I've also always thought of nitric acid as a strong oxidizing agent. I thought it passivated stainless by forming an oxide layer thereon. ??? * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Marc Sedam writes about sulfury Pils and Maibock using Wyeast 2278 (Czech Pils). You, Sir, are making lager beer. Enjoy it! Quips aside, a fellow in my brewing club (BURP) once described this strain as "Smells like a paper factory" (sulfur dioxide is used to bleach paper). I'm surprised you didn't notice anything during primary which is when it's really strong. What you are experiencing now is called "Jungbukett" which DeClerk (or rather his translator) gives as "beer stench". One of the reasons for lagering is to give this stuff the opportunity to take flight. Venting the lagering vessel will help. What might work even faster is to pressurize to say 20 - 30 psig CO2, let it sit for a couple of days, then bleed the pressure (gradually so the beer doesn't explode into foam and come rushing out the gas port) and repeat this cycle a couple of times. The escaping CO2 should scrub out the SO2 faster than just venting the gas produced by the yeast during lagering. Caution: high pressure is reported to inhibit yeast so maybe you dont want to be so dramatic as the numbers I just gave. You could pressurize to 10 psi and bleed to 5 if you are worried about this. Interestingly enough in view of some recent discussion of the participation of copper in oxidation reactions in beer is that elemental copper will fairly quiclky catalyze the oxidation of this sulfite to tasteless sulfate. I don't recommend this treatment for you beer as other things get oxidized as well (the beer turns dark). - -- A. J. deLange Numquam in dubio, saepe in errore. Return to table of contents
