---------------------------------------------------------------------- Date: Mon, 1 Apr 1996 09:19:36 -0500 From: ajdel at interramp.com (A. J. deLange) Subject: Water Raymond Louvier posted this water analysis Silica 12 Sulfate 14 Phosphate <.1 Calcium 33 Chloride 28 Magnesium 8.3 Carbonate 0 Sodium 59 Bicarbonate 239 Potassium 2.1 Nitrate <.05 Total dissolved solids 395.2 Suspended solids 1.3 Total Alkalinity(CaCO3) 196 Hardness as CaCO3 116 pH 7.8 Chlorine Residual NR (?) and commented that his light lagers suffer from "bite". He suspects that this has something to do with the bicarbonates and this is probably correct but sulfate, even at this low level, could also be a contributor at the high hopping levels found in Pilsners. The effects of carbonate are largely felt through the alkalinity (which is mostly caused by carbonate) which results in higher mash pH's than might be desired. One approach is to neutralize the alkalinity with acid (such as lactic) in the mash to the extent that the mash pH is within the desired range (5.2 - 5.4) at sachharification temperature. Some authors believe that high levels of bicarbonate, even if neutralized, will have a negative effect on the beer. The obvious approach is to try to remove the bicarbonate from the water and the usual method is boiling. Boiling is unlikely to precipitate any carbonate from this water. Precipitation is predicted from a couple of "indices". Neither indicates that precipitation will occur although the water will be supersaturated with chalk if boiling raises the pH to above 7.6 which it is, of course, likely to do. While the indices are not infallible, my limited experience also suggests that precipitation is not likely with this water. Remember that leaving boiled water to cool over night will allow it to pick up CO2 from the air so that the pH goes back down and some of the precipitated chalk, if any, redissolves. The bicarbonate can be precipitated by adding lots of calcium (which will benefit the beer in other ways as well) but there are catches to this approach. Gypsum is a source of calcium but also of sulfate so that adding gypsum will aggravate the bite problem. Calcium chloride adds the calcium without sulfate but the chloride also goes up and this may be an approach that could be explored for ales but you already have more chloride than is desireable for some lagers. Calcium chloride is a little difficult to find but someone mentioned that there is a homebrew mailorder house that sells the dihidrate in food grade. Unfortunately, I can't remember who that is. Another source of calcium is lime either as quick lime (calcium oxide) or slaked lime (calcium hydroxide). The problem with them is that a source of food grade lime is difficult to find and that detailed, accurate calculations are required for the addition and even then the results are not fully predictable. DeClerk recommends working with test batches of water followed by analysis before making the adjustments to the production water. All this is too elaborate for the homebrewer. What seems to make most sense in this case is dilution of the municipal water with distilled water. 50:50 dilution will get the alkalinity down to around 100 ppm and this is adequate for most brews. Bohemian Pilsners are always the exception. They must be brewed with very soft water and few brewers are fortunate enough to have water that soft (but I have seen a couple of analyses posted here that fit the bill). For these beers brewers must use distilled or deionized or reverse osmosis water in order to eliminate the bite. You may wish to try a brew with 100% distilled or RO water. Be careful not to sparge past the point where runoff pH excedes 6 (or maybe a bit less, say 5.8) and don't expect great conversion efficiency but the difference between the distilles water beer and what you usually brew will tell you what the effects of your water are.

Date: Mon, 1 Apr 1996 10:27:58 -0500 (EST) From: Paul Ward <paulw at doc.state.vt.us> Subject: Adjunct Question(s) Well, I', finally moving up one carefull notch at a time in this brewing hobby. After several all extract batches, I brewed 'Elbro Nerkte' this past weekend, which was my first experience using adjunct grains (crystal and black patent). Following the guidance of St. Charles the Papazian (and this collective), I placed my grains in one of those heavy plastic bags with a "zipper" closure, set it on my marble pastry board abd beset it with my marble rolling pin. My wife wandered out to see what I was doing in her kitchen. "Crushing my grains," I replied. She asked why I didn't use our electric coffee grinder (one of those new fangled devices with blades in it that can pulverize coffee beans in 12 seconds). I explained that the grains needed to be 'cracked' into 3 to 5 pieces, leaving the hulls intact. "Why," she asked? "So I don't get a stuck sparge or undesirable tannins from the husks in my wort," I answered. "What's a sparge," she innocently inquired? Only then did it dawn on me, I DON'T HAVE A SPARGE TO GET STUCK! "How do the grain husks cause tannins," she next asked? I explained how the husks would release tannic acid if boiled, and it dawned on me that the grains (and husks) are removed from the water BEFORE the boil. My wife smirked and told me to make sure I cleaned her stove when I was done 'playing.' So anyway, my questions are: If I use the rolling pin method, how do I know when I've sufficientlly crushed the grains? That 3 to 5 piece rule leaves a little something to be desired if you don't know what you're looking for. Since I'm not sparging (other than straining througha seive with cheesecloth in it), what difference does it make how small the grain pieces are? Wouldn't finely pulverized particles dissolve more readily (not the particles, the sugars in them)? I heated a gallon and a half of cold water to ~150 F and held the grains at that temperature for about 15 minutes, then raised the temp to the start of boiling when I strained out the grains. Can I cause HSA by aerating this hot 'adjunct tea' by straning before adding the malt extract? Well, that's enough for one morning. I appreciate this forum and the help I have received in the past. Thanks all. Paul - -- If vegetarians eat vegetables, what of humanitarians? Return to table of contents

Date: Mon, 01 Apr 1996 11:52:27 EST From: "Stephen Palmer" <uscgsynd at ibmmail.com> Subject: My First Partial Mash - Description and Questions Well, I did my first partial-mash Saturday night, and I must say that all-in-all it was a good experience. I'm glad I did a partial rather than a full mash, as I did make some mistakes, and the 50% extract may help save the batch. I wanted to do the partial mash with -no- purchase of extra equipment, so my sparge vessel consisted of a 2 gallon bucket with lots-o-holes drilled in the bottom suspended over the top of my 6 gallon bottling bucket. As you might guess, this resulted in the sparge water dripping about 1 ? feet from the sparge vessel to the bottom of the bucket. After collecting my wort, and adding my extract, I had about 2 7/8 gallons to boil (in a 3 gallon boiler) so I had to be very careful of boil over. I successfully avoided boil over, and within 30 minutes had a good rolling boil going. Throughout the process, I was chanting the mantra... Relax... Don't Worry... Have a Homebrew... (And I did) On to my questions. 1: Is hot side aeration going to seriously affect my brew. 2a: The recipe called for 1 lb. brown sugar. I mistakenly added this to the mash, and I'm afraid it all got filtered out during sparge. Will I lose the flavor the Brown Sugar was supposed to add? 2b: My Starting Gravity was Way low. 1.034 instead of 1.047 predicted. I believe this may be due to 2a, or poor extraction during sparge. Will this seriously affect the flavor, or simply lower the Alcohol content? The batch is now in the primary fermenter, and appears to be progessingnicely despite all my attempts to kill it... :-) PS: the recipe was the Partial Mash version of the (Southern) Brown Ale as listed in the back of Dave Millers CHOHB. Basically as follows.. (working from memory) 3.5 lbs British Pale Malt Extract Syrup 1.5 lbs British Pale Ale Malt 4 oz Med British Crystal 4 oz Black Patent 1 oz Norther Brewer Hops (bittering) 1 oz Fuggles (Aroma) Start 8:30 PM Mash in 132F 5 min Starch Conversion 155F 1 hour Mash out 168F 5 min Sparge with 2 gals 168F 1 hour Boil 1 hour NB hops at begin, Fug Hops at end...

Date: Mon, 1 Apr 96 09:25 PST From: fpf at gasco.com (Frank Ferguson x3584) Subject: Advice on getting that "bitter" flavor My brewing partner and I have been fairly successful so far in the brews we're putting together. We've not tried grain brewing yet, but will get there eventually. One problem we've had is getting a truely sharp, bitter taste in our bitters. By and large, we've wound up with a tendency for a somewhat sweet and gentle bitter. What's the secret? We've certainly let things ferment to the end, and have applied what seems to have been the right variety and amount of hops. It there something we're missing here? Any help appreciated. francis ferguson fpf at gasco.com Return to table of contents
Date: Mon, 1 Apr 1996 12:26:43 -0500 From: KennyEddy at aol.com Subject: Carbonates and Water Analysis & Synthesis I've been in some discussions about water analysis/synthesis with regards to "carbonate" and "alkalinity" and am presenting the following for review and comment. In developing BreWater as a tool for massaging water makeup for brewing purposes, I've discovered that there are certain aspects of the problem which are simple and straightforward and certain others which are aggravatingly flaky. Adding one gram of table salt to a gallon of ion-free water DOES result in 104 ppm sodium ion and 160 ppm chloride ion. Adding one gram of chalk DOES result in 106 ppm calcium ion and 158 ppm carbonate. The difference is that in the case of table salt, what you see is what you get. It's it and that's that. In the case of chalk (and baking soda), the "carbonate" has its own plan... "Carbonates" exist in water as a mixture of carbonate (CO3--), bicarbonate (HCO3-), and carbonic (dissolved CO2). with the relative concentrations of these "species" depending on the pH of the water. In the case of water synthesized with only chalk and/or baking soda, the concentration ratios and the resulting pH is actually predictible from the amount of chalk and baking soda added. On the other hand, the pH of a "natural" water may be further influenced by any number of other water components. The problem is compounded by the fact that published water profiles may give the carbonates under either "CO3" or "HCO3" labels. This may be based on an assumption that at the pH of the "natural" water, there is a predominance of one or the other. It may also be a default, blind "lumping" of all three carbon species into one figure for "simplicity". In any case, it's only part of the story. The "buffering" capacity ("alkalinity") of a given concentration of *carbonate* (say from chalk) versus *bicarbonate* (say from baking soda) is different, and it's the *buffering capacity* that we are really interested in, since this is what counteracts the mash's ability to acidify to "optimum" pH levels. If one profile gives "carbonate" and the next "bicarbonate", is the author blindly "lumping" all the species under one label or is s/he assuming a predominance of one over the other based on other water characteristics? Or perhaps s/he is giving the equivalent (bi)carbonate concentration which gives rise to the water's alkalinity? How should we deal with the "carbonate", "bicarbonate", and "alkalinity" figures in working with BreWater (or any other water adjustment plan)? For additions of chalk and baking soda, BreWater adjusts the alkalinity contributed by them based on the fact that bicarbonate (from baking soda) is half as "alkaline" (half the buffering capacity) of the carbonate contributed by chalk. 100 ppm "CO3" from chalk is twice as alkaline (166 ppm) as the alkalinity from 100 ppm of what's labelled "CO3" (actually HCO3) from baking soda (alk = 83 ppm). Whether the alkalinity exists as carbonate or bicarbonate doesn't matter as much as the solution's alkalinity or buffering capacity. The label "CO3" in BreWater could perhaps be more accurately labelled "HCO3" since water synthesized only from BreWater's salts will have a pH in a range where bicarbonates dominate, but in "natural" water further treated with salts, it's not an easy task to determine the mix without lots of additional information. In either case it's not going to be totally right since it will always be a mix anyway. The use of the "CO3" label arises from the desire to express "as CaCO3", which is typical of a municipal analysis. Bottom line is that if the alkalinity is kept under control, the number under the "CO3" label is not that important. In a few rare cases the target profile's alkalinity is given, but in most it is not. Fortunately, the *total alkalinity* of "your" starting water (tap water or whatever) is usually given in the municipal supplier's analysis. The additional alkalinity supplied by additions of chalk and/or baking soda will yield a final alkalinity figure that should accurately represent the resulting *alkalinity* of the brewing water. But how does that relate to a target profile giving only "carbonate" or "bicarbonate", but not "alkalinity"? If a target calls for "75 ppm CO3" without stating "alkalinity", what's the synthesis plan? This is where I get dizzy and begin wheezing, so if I'm off-base here, I'd appreciate some help. The following will result in rough estimates rather than exact figures, but should at least put you on the right planet. One very rough approach might be to assume that the resulting water will be in the range of pH where bicarbonate predominates, and to go with the equivalent 1 ppm bicarbonate = 0.83 ppm alkalinity. So "75 ppm CO3" means "75 ppm bicarbonate" which equates to 62 ppm alkalinity. This will most likely be "wrong" but in the absence of other information it should give you an order-of-magnitude figure to use. Once you have the alkalinity figure, use it as a target rather than "CO3" when adding chalk and/or baking soda. What about dealing with a municipal analysis in terms of deriving "CO3" and "alkalinity" figures for starting water makeup? In situations where neither is given outright, you'll have to play some games too. Using the "total alkalinity" figure for "alkalinity" should be accurate. In the range of pH < 8.4, the "bicarbonate" and the analysis' "total alkalinity" figure would be roughly the same. Above this pH the picture changes. But realizing that municipal analyses are averages and often vary greatly over time, this is probably as good a "guess" as any, and again will give you a starting figure which will give you an idea of where your water is on the brewability scale. So using "total alkalinity" for both "alkalinity" and "CO3" would be reasonable. Now you have both beginning and target estimates for alkalinity, so add your chalk and baking soda using target alkalinity rather than target "CO3" as a guide. In any event, it's a good general "rule" to minimize alkalinity, so view this estimate as a maximum in any event. For straight synthesis from ion-free water, BreWater equates the bicarbonate from baking soda to the equivalent amount of CO3 by accounting for the extra hydrogen atom in bicarb (it multiplies HCO3 by 60/61). The 2:1 ratio of alkalinity between CO3 (chalk) and HCO3 (baking soda) as described above is also accounted for. So the resulting calculation yields an "as CaCO3" figure for CO3, and an adjusted "alkalinity" figure.

Harsh) Subject: Force carbonating 5l mini-kegs In HBD 1999, Bob Bloodworth asked: >Question for the HBD: Has anyone out there tried to build an adapter to force >carbonate beer in one of these 5 ltr cans? Force carbonation in these cans is simple. All you need is a tap that accepts CO2 cartridges and a Liquid Bread carbonator cap. The carbonator cap screws onto the threads that hold in the CO2 cartridge and you can connect your ball lock fitting from for CO2 cylinder. Fill the keg, chill, carbonate as usual. One word of warning - the newer version of the carbonator cap has a ridge around the inside that helps the seal against the PET bottle. You will either have to cut/chip the ridge out or use an old version for force carbonating. This works great - its an easy way to take some of your beer to a party with minimal brain damage and bottle transport. And its a lot easier to shake a 5l keg to force carbonate that it is a soda keg! I've actually kegged a portion of a batch and dispensed it this way connected to the CO2 line instead of using the cartridges. Thanks to Ed Westemeier for originally describing this technique in an article for the Bloatarian Bulletin. As always, void where prohibited, your results may vary, observe safety precautions when handling compressed and/or liquified gases, don't blame me if you hurt yourself trying this.

There's a solution to your problem that involves a bit more time and expense than you would normally want to expend to recover a stopper from your carboy. The trick is to find a mathematician who is a glass-blowing hobbiest. Have him (CAREFULLY!) re-configure the carboy as a Klein bottle (more-or-less the 3-D equivalent of a Moebius strip). Once that is done, the carboy will no longer have an "inside" or an "outside", and you should have no difficulty removing your hand. Of course, a "Klein carboy" may pose some unique problems for filling and sanitizing, but I leave the solution to those as an exercise for the student. :) _John_ Return to table of contents

The answer is a very simple yes. At the auto supply shops, one can buy rubber tire air valve that will just fit into the press out bung hole in the mini-keg stopper from the inside. By fitting your CO2 tank with and tire air filler assembly (again from the auto supply store) you can then force carbonate the mini-kegs. When you get ready to tap the keg simply push in the air valve into the keg as you would the normally push in the bung. Works like a champ. My original concern with this was that the rubber in the air valve would add an unwanted flavor to the beer, but having tried beer dispensed in this manner, I can report that it worked and didn't taste any different. The cost to try this is only a few dollars. Dave Houseman Groundhog Brewery Return to table of contents

Unmalted Rye will give you -no- color and a -lot- of flavor. I have no experience, firsthand or otherwise, with malted rye. If you want to use unmalted rye (which can be great in some recipes), try to find "flaked rye" from a healthfood store - already gelatinized and much easier than boiling rye berries or something like that. -R Return to table of contents

If I had to take a guess, I'd say it's not what -is- in those beers, but rather what is -not- in them. First, most of "cheap beer" you buy is going to be heavily filtered, which will take out the zinc and B vitamins and other nutrients you might get from yeast in -some- good beers. Second, most cheap beers have very little in the way of protein and residual sugars, compared to Guiness or a good bock or a homebrew. A serious deficit in any of these things can influence behavior, and people vary in their sensitivity to them. However, all of them can also be found in a good meal. So, have your wife eat while drinking. Do some experiments. :-) The one thing that some really cheap beers will have more than "regular" beers, but less than many homebrews and exotic beers, are fusel alcohols. I mostly associate those with a "harsh" taste, a headache (both before and during a regular hangover), and a 'confused' feeling. I don't know if they'll make someone resemble a squirrel or other small mammals, but it's feasible. -Russell Mast copyright 1996 Bat Pabcock Return to table of contents

(I mash the adjuncts with the base malt) Definately. Adjust your expectations of extraction based on the different content of your mash. btw, crystal malt is a 'specialty grain' which is very different from an adjunct.

I would never waste my time with a hydrometer during a sparge. Taste the stuff. If it tastes bad, don't use it.

I have a ballpark idea of my rather variable extraction rate, and I use that to figure how much grain I'll need. Beyond that, I don't worry much about it, and I don't really know why anyone does.

One of the other members of the brewing club I belong to has indicated that the "carbonator" adapter (designed for 2L PET bottles) can also be attached to the 5L mini-keg tap.

I saw a nice idea. Mike O'Brien of Pico Brew showed me that the "Carbonator" (a little device that uses the snap on connector that goes on a corney keg to carbonate PET bottles) screws right onto the mini keg tapper where the CO2 cartridges go. The tapper he showed me was one of the metal (i.e. higher priced) models. Make sure that they are compatible before buying. No interest in either company blah blah.

Date: Mon, 1 Apr 96 13:04:32 CST From: korz at pubs.ih.att.com Subject: Wyeast Strains Remember a while back when Tom Fitzpatrick said that he spoke to Dave Logsdon at Wyeast and got the origins for many of the yeasts? Remember when I posted that Dave usually doesn't give out the the sources and that I was suspicious of Tom's confidence in the yeast sources. Well, I just got off the phone with Dave and asked him straight up if he told Tom that Thames Valley Ale (#1275) is from Henley and that Belgian Strong (#1388) was from Duvel. Dave responded just as I remember him responding when I asked him about sources three years ago: He said "...well, Tom may have gotten the impression... we don't usually give out the sources... these may or may not be the sources..." I'm not saying that they are the sources of the yeasts, nor am I saying that they are not. Furthermore, I'm not saying that Dave is not telling the truth nor that Tom is not telling the truth. What I suspect, is that Tom asked Dave point blank and that Dave gave a half-yes-half-maybe answer (as he has always done with me) and Tom interpreted that as being a yes. I have talked to Dave about sources many times over the last six years or so and he has always been rather protective and non-committal. I don't blame him. I don't blame Tom for thinking he got a definate yes from Dave. I thought the same thing when I first talked to Dave about sources. So, if you think that you know where a particular yeast is from and it makes you happy and you can brew a killer Duvel clone from #1388, great! But, don't take any of the matchings of Wyeasts with sources too seriously because there is an awful lot of speculation infused into those matchings. Al.

I have had great success with the Alexanders Sun Country Pale Malt Extract. I have decided to use this in a base for most of my future brews because I understand that most brews begin as pale. The eventual color, taste...of the finished product depends on where you go from there(hops, grains...). Anyways, I can elaborate on a real easy recipe for using an unhopped malt extract (Alexanders or otherwise) if you want to e-mail me. We don't want to plug up the bands with Extract gibberish now do we??? The finished product comes "close"(I use quotes because I don't want to degrade my brew anymore than needed) to the taste of a comercial brew you want to serve your non adventerous/handcrafting appreciative friends.

Date: Mon, 01 Apr 1996 20:29:41 -0600 From: Dave Corio <dcorio at inav.net> Subject: Wort Cooling Hi, Clay. Had the same problem here, as house is kept fairly warm for tropical birds. This tip from the local Brewmeister did the trick for me. I keep my 6 gallon carboy in a plastic (metal would work) tub, with about 3 to 6 inches of water in the bottom. A good sized towel wrapped around the carboy and touching the water will act like a wick, sucking up the water, and cooling the wort by evaporation. That kept the wort temp down to about 68. I picked up a cheap ($7) clip-on fan at Target, and on low setting aimed at the towel, the wort stays a nice chilly 60 degrees! Just a couple of warnings! I go through about a gallon of water a day, and that's here in Iowa. You'll probably go through more if your part of Texas is arid. Also, if you use a water-filled airlock on top of your fermentor, set this up prior to adding the yeast. If you drop the wort temp with the yeast added, it can (and has) sucked the water right out of the airlock into the wort. This cooling will also extend the fermentation time, and also result in much less violent fermentation. I've CC'd this to the collective, just in case I really have taken leave of my (few) senses and someone wants to set me straight! On the other hand, this may be a valuable hint! Good luck.
