---------------------------------------------------------------------- Date: Mon, 16 Mar 1998 14:31:07 -0500 From: AJ <ajdel at mindspring.com> Subject: pH & Temp/Microscopes/Rolling Rock RE: Temperature and pH. I can find authors that say pH is always specified at the temperature of the reaction and other authors that say it's at room temperature. Readers need to be careful. The issue here is, of course, the mash where we are focused on the effects of enzymes. I believe in the enzyme biz the pH is specified at or close to the temperature at which the enzyme is most active. Steve? As we know that room temperature specs are sometimes used I agree with Dave that we should always specify what we mean when writing ourselves. Dave's post had a couple of interesting data points on the distilled water pH of mashes and I'll add one. M&BS says 5.8. I find 5.6 - 5.75 for the DWC light malts I've measured (at room temperature... almost forgot). Dave gets around 5.6. Ken Schwarz (as reported by Dave) got 5.3 but Daves's post said "malt", not what kind. I have to believe it was crystal or carapils or something higher kilned than the usual base malts. The significance of all this is that the distilled water pH depends on the malt (patent will give pH's well under 5). Also significant is that the rise in pH as wort cools depends on the grist. DeClerk has some tabulated data (for a particular grist compositions and water types) which suggest an increase 0.3 over the typical span from saccharification to room temperature and and that's probably a reasonable rough number. Just bear in mind that the smaller the temperature delta, the smaller the increment. Since I started worrying about this I have been measuring all pH's at room and mash temperature. I have yet to see a rise of as much as 0.3 pH; 0.2 pH is more typical for me. Dave commented that pH papers and meters work best at room temperature. I don't see why a pH meter would work any better at room temperature unless the reference were calomel and we don't use calomel electrodes in our brewing. Right? Calomel melts at about 55C (if I remember correctly). For brewing we want a double junction reference (see earlier in this post). Granted an electrode will last longer if operated at lower temperature, even if it's spec'ed to 100C. I think it's the thermal stress on the glass in changing temperatures that shortens life more than exposure to the high temperature and I don't think mash to room temperature changes (as opposed to kettle temperature, which exceed 100C, to room temperature changes) are that stressful. With papers I really don't know what to think except that they rely on dyes whose colors depend on the degree of dissociation (i.e. the dyes are acids). As the dissociation constants depend on temperature the response has got to change with temperature as well. Whether the color change from this effect is significant or not isn't something this color blind brewer should be commenting on. In any event, by the time the strip has been dipped and removed for reading, it will have cooled. Will high temperature during the dip destroy the dye? * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Ray Estrella asked about microscopes. This is another expensive item with the major issue being that yeast are hard to see unless they are stained or a phase contrast microscope (read "extra $") is used. Now Ray mentioned viability studies in his post. This is done by staining with methylene blue so if that's to be done one might get along well enough with a bright field 'scope. Unfortunately it's the dead cells that take the stain so that those would be the ones that would most easily examined for morphology. You wouldn't be able to make out the interior structure of the living cells as well and one does sometimes look at things like vacuole size to determine how well fed yeast are. Now you _can_ see interior structure to some extent with bright field. It's just harder. For enumeration only bright field is fine. The count is usually done at low power and there is no question of looking at morphology. This is also true for viability where one counts total cells distinguishing the colored from the colorless to compute the viable fraction. I'd try to find the best microscope I could get used. A microscope is definitely one of those things where "the bitterness of poor quality remains long after the sweetness of low price is forgotten". Scopes are expensive but optics don't wear out no matter how much light you run through them (though the mechanical parts - focusing mechanism, slide positioner, etc. do wear). A used 'scope in good condition should be absolutely as good as a new one. For enumeration and viability 60X should do. To see morphology and check for bacteria in yeast samples 400 - 600X is enough. Higher powers (real high power - not the "empty magnification" found in cheap microscopes) usually require oil immersion objectives and you don't want to have to mess with that if you don't have to. Another big price swinger is monocular vs. binocular. Binocular is much more comfortable but it's something you have to pay extra for. Louis Pasteur didn't have a binocular 'scope (or phase contrast) and you don't need it either. * * * * * * * * * * * * * * * * * * * Jason asked about how to make Rolling Rock. With tongue only partly in cheek I advise brewing up a light lager with a hefty percentage of adjunct and boiling for a fairly short time with the lid on. Do not use a wort chiller but rather allow the wort to come slowly to pitching temperature. (I use 'Rock to train BJCP candidates in recognizing DMS). Return to table of contents

HBDers, Anybody know where I can buy a SS pizza pan like the ones you see made of aluminum? I've been using an inverted aluminum pizza pan as a hop filter on the bottom of my boil tun, but it's starting to look all beat up. Thanks, Mike Spinelli Return to table of contents
Date: Mon, 16 Mar 98 14:17:40 est From: paa3983 at dscp.dla.mil (Mike Spinelli) Subject: Bleach and SS/Lactic acid HBDers, Can someone out there (like John Palmer) tell us the real poop on how really bad bleach is to SS and other metals? I know all the "books" say bleach is a no-no, but I've also heard that bleach is OK when the contact time is kept to a minimum and the solution is weak. I've been submersing my copper helical coil heat exchanger CF chiller in bleach water for about 5-10 mins. prior to use. Am I wreckin' it? - ---------------------------------------- Dan Johnson asked in #2660 about the proper use of lactic acid to adjust sparge water pH. Don't know if it's proper, but here's what I do. Heat sparge water to around 150-160. Squeeze a bit of lactic acid in the tank and stir around. Take out a colorpHast test and dunk it in the tank. Check the color. I usually adjust til the strip reads in the mid 5s. I've read that water temp. can afffect the reading so I'm probably wreckin' this too.

Date: Mon, 16 Mar 1998 15:10:44 -0600 (CST) From: Al Korzonas <korz at xnet.com> Subject: mead myth Jon writes that boiling makes their meads clear faster. There is a tradeoff here... boiling also reduces the aroma of the finished mead. I do not boil my mead musts at all and, yes, they do take more than a year to become clear (some never clear at all), but the mead I made that won in the AHA Nationals was (and still is) rather cloudy. It's not as pretty as some meads, but it sure smells and tastes good! Also, just as a datapoint, my winning mead was only five months old in the first round and around 7 months old for the second round. I feel that my rather cool fermentation (around 62 or 63F, I believe) helped keep the higher alcohol production down, which meant less need for aging. Al.

Date: Mon, 16 Mar 1998 17:10:51 -0500 From: John Varady <rust1d at usa.net> Subject: Porter: Brown or Robust Who can tell me major differences between a Robust and a Brown porter? I posted a couple of months ago about a porter that I brewed using a Bavarian lager yeast. So far I have entered it in 3 competitions, twice as a brown and once as a robust. Here are the results and the judges ranks: ** Keystone Hops ****> Entered as a Brown Porter: Second Place BJCP Certified: 35 BJCP Recognized: 33 BJCP Recognized: 34 ** Brooklyn MBAS ****> Entered as a Brown Porter: Second Place BJCP Recognized: 37 Unknown: 36 BJCP Certified: 34 ** Boston HBC *****> Entered as a Robust Porter: No ribbon BJCP Master: 40 Experienced: 38 BJCP Certified: 39 BJCP Certified: 33 Honorary Master: 37 So apparently, not even BJCP certified judges can tell the difference between these two styles. Not one comment to the effect that the beer would have been better entered as the other type of porter. Are they considering adding yet another style of porter to the list? So while I don't know which type of Porter to call it, I know it is a damn fine beer. Gulp, John John Varady * New email address ***> rust1d at usa.net Glenside, PA Return to table of contents
Date: Mon, 16 Mar 98 14:25 PST From: cburns at egusd.k12.ca.us (Charles Burns) Subject: Dubbel Yeast Gordon Strong <strongg at earthlink.net> asks about Dubbel yeast in hbd#2662: I am interested in determining what variety of Wyeast is best used for a Belgian Dubbel.<snip>, so I request comments be limited to fermenting a classic Trappist-style Dubbel using Wyeast. Last June I made a Dubbel with Wyeast 3787, Trappist. OG was around 1.080. I didn't like the results at first (clovey/spicy) but over time it mellowed big time. Yesterday afternoon I consumed the last bottle with 3 friends. I hadn't had any in at least 3 or 4 months. I was amazed at how good it had become. I have vowed to make the recipe again, bottling it and storing it for a year before consumption. YMMV, Charley (with no more belgian beer) in N. Cal Return to table of contents
Date: Mon, 16 Mar 1998 17:02:35 -0600 (CST) From: Al Korzonas <korz at xnet.com> Subject: Priming Dave writes: >To repeat, prepare a priming starter using beer and yeast >from the secondary. Add priming sugar and a tablespoon of >malt extract which have been dissolved in a minimal amount of >boiling water and the mixture cooled. Allow to come to >kraeusen in about 12 hours and bottle by adding a fraction of >this to each bottle to minimize HSA from bottling .

Before you give >me the notoriety of making me part of your webpage - try it. It is controversial because I (as a relatively experienced hombrewer) can tell just from reading it, that it *can* result in inconsistent carbonation. One need not actually try something to know that it has potential problems if it has obvious flaws "on paper." I don't have to try Garetz's hop utilization formulas in practice to know that they will give me 50 to 75% more bitterness than the formulas I use now. I didn't want to get into this, but you have introduced a new twist and I can always use this text for my webpage. The reason I feel that this method will result in inconsistent carbonation is because you cannot really be 100% of how much of that sugar and malt extract will ferment away during that "about 12 hours." My fermentation area and my living space both fluctuate as much as 15 degres F over the course of a year. Even 10F is enough to make a *BIG* difference in how much of that sugar and malt extract ferments away in those "about 12 hours." I presume that you are doing this because it somewhat imitates the time-honoured tradition of kraeusening, used by German brewers. In a way it does, yet there is a big difference. The German brewers are repeatedly making a small number of recipes which they make consistently (with typical German precision). They always have a batch of beer fermenting when the time comes for carbonation on an earlier batch. What they do is measure the SG of a fermenting batch and (because they know what the FG will be) calculate the residual fermentable sugar very accurately. They now can prime the finished beer with the fermenting beer *BUT* they *VARY* the volume of the fermenting beer (this is the kraeusen) that they add based upon the residual fermentable sugar. In your method, this can vary significantly and therefore carbonation can vary as a result. Secondly, I have had absolutely rock-solid, predictable carbonation in all but one of my 200+ batches of beer in which I used standard batch priming techniques. In fact, I started using corn sugar for priming, but changed to malt extract after a year or two. My beer took *longer* to carbonate. There was also a ring of material around the neck of the bottle at the beer line. I contend that this was protein because it disappeared when I went back to corn sugar (and has not reappeared in the last 7 years of corn sugar priming). I feel no need to change my priming method if it has worked so *reliably* for me all these years. Note that the one batch that took extremely long to carbonate was a 1.120 OG Imperial Stout and the issue there was the high alcohol content and not the sugar or lack of FAN. In this case, I should have pitched some fresh yeast. Thirdly, you say that you do this to provide sufficient FAN for the yeast. FAN is needed for growth. The fermentable material we add at priming time is between 1/35th and 1/100th of that in the primary ferment. Presuming that you had sufficient FAN in your original wort and gave your yeast enough oxygen, they will not need more FAN to produce carbonation. There is no need for growth during carbonation (and, in fact, it is undesirable... I want the minimum amount of yeast in the bottle, not more growth). Finally, you say that you add the primings to each bottle to minimize HSA from botting. I suspect that you mean oxidation because HSA is associated with hot wort. Indeed priming each bottle does eliminate the need to rack the beer once (from fermenter to the bulk priming tank), but I feel that the additional work of measuring the primings into each bottle far outweighs the possible additional oxygen uptake from the additional transfer *and* depending on how you do it, can introduce oxygen if the primings splash into the bottle. I bottled five batches yesterday, so my methodology is very clear in my head. I make up a solution of corn sugar (weighed) and water in an erlenmyer flask and bring it to a boil. I cover the top with a square of foil. I sanitize my priming carboy and purge it with CO2. I begin racking wort into it, via siphon. I delay the addition of the hot primings until there is a quart or so of beer in the carboy so that the nearly boiling primings do not crack the carboy. Beer is quickly running (gently... I keep the plastic bottle filling tube, minus the valve, on the end of the siphon tube so that the beer does not splash into the priming carboy) into the carboy, so there is a positive displacement of the CO2 out as I pour the priming solution down the outside of the bottle filler tube. Whatever splashing does take place is in a mostly-CO2 environment. Once the racking is finished, I switch the racking setup around, while removing the orange tip that keeps the racking cane off the settled yeast and putting the filler valve on the bottling tube. I then gently stir the beer and prop up one side so I can get every drop of beer. I have a carboy handle on each carboy, so I attach a rubberband to it to hold the racking cane in place, both during racking and bottling. I adjust the rate of filling by varying the height of the bottle relative to the level of the beer in the priming carboy (I start out high so the beer does not splash into the bottle and then lower it to speed up the rate). As a testament to my bottling technique (and the lack of HSA earlier in production) I had a 1.035 OG English Dark Mild that made it to the 2nd round of the AHA Nationals *18 months* after bottling!

Date: Mon, 16 Mar 1998 20:56:02 -0700 From: "Brian Rezac" <brian at aob.org> Subject: Big Brew '98 This year, the American Homebrewers Association celebrates its 20th Anniversary as well as the 10th Anniversary of National Homebrew Day, the only national holiday that celebrates beer and brewing. We felt that to properly celebrate these significant occurrences, we needed an equally momentous event. What we came up with is Big Brew '98. Big Brew '98 is the record-setting attempt of the simultaneous brewing of many small homebrew batches of the same beer recipe by homebrewers across the nation. Big Brew '98 will take place on National Homebrew Day, Saturday, May 2, 1998. The plan is to have homebrew shops, clubs or even individual brewers host and oversee each brewing site across the country. Then, on the day of the event, homebrewers would brew at these registered sites. We will gather information, such as, total number of participating brewers, total number of gallons brewed, total amount of hops and total malt used, etc. Currently, I have a proposal in front of the Records Committee of Guinness Media, the publishers of Guinness Book of Records for them to include this homebrewing record in the 1999 version of their book. However, we do not have a guaranteed commitment from them that this record attempt will be included in their book. Yet! The recipe that we will be brewing, "Big 10/20", is based on Little Apple Brewing Company's "Big 12" Barley Wine, created and brewed by Rob Moline and winner of the Gold Medal in the Barley Wine category at the 1996 Great American Beer Festival. We will have two versions of this recipe, an all grain and an extract/steeped grain version. We will be flying Rob out to Boulder to have him available to homebrewers via an online chat room on the day of the brewing. Big Brew '98 is being sponsored by Lallemand Inc., Briess Malting Company and Schreier Malting Company. Because of their support, there's is no cost to homebrewers to participate in Big Brew '98. We truly hope this event will encourage homebrewing at all levels by any and all homebrewers throughout the country. In addition, let me say that often in groups or forums, we homebrewers discuss differences in brewing levels, techniques and opinions. It's time we come together to celebrate our similarities and simply homebrew a batch together. I invite and encourage all of you to participate. For a more information on Big Brew '98, including the "Rules & Regulations", send an email to me at brian at aob.org with "Big Brew '98 Rules" in the subject line.

George de Piro says: "Maybe I'm too much of a cynical paranoid lunatic, but while I search for answers I can't help but think, "They dump the bad batches of malt overseas and on the homebrew market." Well I cant speak from Marris Otter experience but I can speak at great length about the poor service and quality that we receive from the big maltsters here in Australia. Over the 2 years I have been brewing I have yet (until recentlly) received ANY malt that would qualify as high-grade professional quality. I have used malt from Adelaide (The Coopers maltsters) and from Joe White maltings in both Ballarat-Victoria and Redbank-Queensland. On one occasion did I manage to obtain an analisys, whilst on all others did they effectively tell me to GET STUFFED. When I did get an analisys from Joe white in Queensland, the malt was so highly modified (Kolbach 53) that most brewing journals cited this in the region of "cattle feed". Needless to say the malt created the worst beers possible, with little malt flavour and poor conversion. I KNOW this was reject malt. I spoke to the former head brewer at Castlemaine Perkins, who assures me that an acceptable malt would have kolbach around 41 or so..... Now on to Adelaide maltsters Inc.... The malt that my brew-club purchased was oridinary to say the least. Size may as well varied from pin-heads to tennis balls. The bags were marked with "VIETNAM" and needless to say, we get these bags because the Asian customers rejected them on the basis of crap sieve assortment. On the various occassions that i have contacted Joe white in pusuit of any help of technical feedback, the moment that find out Im not from Carlton United breweries Australia, they dont want to know me. END OF STORY. Ive heard that our friends in New Zealand, HAVE TO import malts for Micro beers, as the big maltsters are not permitted to sell them any by the big brewers. SO MUCH FOR FOSTERING COMPETITION POLICY!!! Anyway its obvious that as homebrewers we are at the lowest point on the pile. I firmly agree with you George. Unless you want to purchase several million tonnes a year from them you are a NOBODY. If I ever win the lottery I will open a brewery and go to great lengths to get my malt from anybody, but Joe White. Vent Your spleens at the big boys on the HBD today!!!!

Date: Mon, 16 Mar 1998 23:00:55 -0800 From: Mearle Gates <mearle at orcalink.com> Subject: Brewer's WorkShop Software Fellow Home Brew Digesters: Specifically those who use Brewer's workshop (and probably other brewing software as well), you will want to be aware that many style definitions are now changed in the 1998 AHA style gidelines. For example Marzen/Octoberfest now has an upper gravity of 1.056 - down from 1.059, new styles are added like Oatmeal Stout (but still no rye beer!), and style descriptions are more lenient toward chill haze, while many many hop level descriptions are revised. Keep in mind I am comparing to Brewer's Workshop 4.04 specs. One should either tediously edit the style info in your software, disregard it entirely and keep a Spring 1998 issue of Zymurgy at hand when preparing recipes, or bug the software manufacturer for a revised copy. Beer judges had better review those AHA style descriptions again also! Mearle Gates Tumwater,WA http://www.gototem.com/Beer.html Return to table of contents
Date: Tue, 17 Mar 1998 00:45:51 -0600 From: "Rob Moline" <brewer at ames.net> Subject: Jethro Gump on George De Piro George De Piro.... I will confess to being way behind in my HBD reading of late, but was up late here and pulled down and opened the latest... I was appalled to see a comment on my friend George, claiming that his experience is insufficient to comment on a subject... Nothing could be further from the truth....in fact, while we were at Siebel together, I will allow that he and I were certainly the most interruptive of the lessons with our questions....I even asked Mr. Siebel about this...should one keep questions for the end of each session, such to minimize distractions, or just ask when the question occurs...I was told, "We are here to serve you, ask whenever you feel the need," and we did.... To the extent that one lecturer, who has spent decades in the business, both domestically and internationally, in a lecture on beer styles was questioned by George regarding the differences between Northern and Southern styles of English Brown Ales. George felt that the notes that the lecturer had passed out and was referring to were in fact reversed, i.e., that the notations for Southern ales belonged to the northern ales and vice versa..... The lecturer took this in good spirits at first, but stated that George was wrong..... George then rephrased his comment, and it was easy to see, irritated the lecturer with his closing comment on the subject that he (George) must be mistaken, and he would look it up at break, but he had learned that such was so.... at the beginning of the next class with that lecturer, the instructor asked us to open our notes to the relevant pages and correct his mistake, and that indeed George was correct after all. "STANDARD DISCLAIMER....(.Insert Here.)...I make no money off George, and don't even buy his products...." I had never met him prior to the 2 weeks we spent together at Siebel ....... George De P is among the most talented and knowledgeable amateur brewers I have ever met....if I only had a fraction of his knowledge!.....why he is not brewing professionally is beyond me.... Indeed tonight, I sent him a question to ponder regarding my current situation regarding the water I brew with, prior to reviewing todays HBD. Shoot from the hip, if you will...but if you are shooting at George, you'd best know your stuff.......'cos George does.......

I want to motorise it. How strong must the electrical motor be and what is the optimum rpm speed to which I can let the rollers run ? With optimum I dont mean necessarily the fastest, I still want to obtain a good consistent crush. Thanks ! Braam Greyling Return to table of contents
Date: Tue, 17 Mar 1998 08:34:19 -0400 From: AJ <ajdel at mindspring.com> Subject: Pilsen from LA/Well Test This is a little old. The local POP pooped over the weekend and I had no desire to go into work. John Palmer asked about synthesis of Pilsen water from Sparklets and gave the following for Sparklets. Bicarbonate 5.8, Alkalinity 4.0, Ca 0.7, Mg 0.8, Hardness 5.1, SO4 3.4 presumably all mg/L as the ion except for the hardness and alkalinity which would be "as CaCO3". There is a problem with the alkalinity number. Pure water has an alkalinity of about 2.5 ppm as CaCO3 so that there is only 1.5 ppm carbonate alkalinity and that corresponds to 1.8 mg/L whereas if we assume that all the alkalinity is from bicarbonate we would have 4.8 mg/L carbonate. Neither of these numbers agrees with the reported number and this is not atypical. I arbitrarily decided to accept the bicarbonate number rather than the alkalinity number. I have three profiles for Pilsen on hand. Two don't "balance" very well and so I chose the third. I can't calculate balance for John's profile because there is no sodium or chloride data. I calculate the following when 11 mg/L calcium chloride dihydrate, 7.5 mg/L epsom salts and 6 mg/L calcium carbonate are added to each liter of Sparklets: Ion AJ Profile Result John's Profile Ca 7 6.1 10 Mg 2 1.5 3 Na 2 0 - HCO3 15 12.7 3 SO4 5 6.4 4 Cl 5 5.3 - A little CO2 would be required to dissolve the chalk and set the pH to a reasonable value. I doubt that it would matter very much to the final beer whether one made the mineral additions as calculated above to the Sparklets water or just added 25 mg/L calcium chloride which would get the calcium to 7.5 mg/L and the chloride to 12 mg/L plus whatever was already in the water. The residual alkalinity is so low (0.08 mg/L) that even 6 mg/L calcium is enough to neutralize it. A change of 10 ppm Ca amounts to a change of 0.14 mEq/L neutralizing capacity which moves pH only about 0.01 pH. Thus it doesn't really matter whether you add any calcium or not. Mashes with this water are effectively distilled water mashes. Mash pH will be set by the crystal/caramel malt component of the grist. * * * * * * * * * * * * * * * * * * * * * * Randy Reed asked about the results of his post softener well water test. By all means have the water tested before it enters the softener. We can't say much about what went into the softener based on a post softener test, at least about cations. Anions are undisturbed by the softener and so we can observe that the chloride level is very high at 130 mg/L to the point where one might suspect leakage of brine into the output stream but if you live in an arid area this might not be that high a number at all. Nevertheless, beers made with this water are probably going to taste salty dependent on how much sodium and potassium are in the input water. Sulfate is very modest at 13.2 mg/L, low enough that soft lagers (Helles, for example) could easily be brewed with this water. We can make a rough guess as to what the hardness of the well water might be by assuming that all chloride ion came from sodium chloride. The report shows 4.5 mEq/L sodium at the output of the softener and 3.67 mEq/L chloride. This would leave 0.89 mEq/L sodium exchanged corresponding to a hardenss of about 45 ppm as CaCO3. A couple of other comments: -the pH is at the USEPA recommended limit for pH i.e. 6.5 -iron at 0.08 mg/L is well below the USEPA secondary limit of 0.3 mg/L but dangerously close to the brewer's desired limit of 0.1 mg/L especially as this is at the output of the softener. There well may be a iron problem with this well. Iron can be removed by agitating the water to let CO2 out and let oxygen in. The combined effect will be to raise the pH causing ferric hydroxide to precipitate. -there doesn't seem to be a USEPA limit for sodium though the WHO has a guideline that it be under 200 mg/L and you are well under that.

Date: Tue, 17 Mar 98 05:40:14 MST5EDT From: Sharon/Dan Ritter <ritter at bitterroot.net> Subject: shipping beer with dry ice Those of us that will be entering beer in AHA's Nat'l HB Competition will once again face the daunting task of shipping temperature sensitive beer across the country IN JULY! Someday I hope AHA will heed the call and move the competition dates earlier in the calendar year. Until then I have been wondering if it is possible and effective to ship beer with dry ice. I ship my beer in a foam lined shipping carton designed specifically for beer (from the Case Place). There are usually one or two empty beer slots where dry ice could be wrapped in plastic and secured. They would be insulated from contact with the adjacent bottles yet might provide enough cooling to keep the beer from reaching the boiling point as it passes through Lubbock, Texas when the afternoon high is 105F. (My apologies in advance for those that live in or near Lubbock for stereotyping your weather. I have no idea about the weather there but you get my point. And yes, I know the NHC finals are in Portland this year but brewers in Austin will have this problem!) Has anyone tried this? If so, what quantities of dry ice did you use? Is it effective and what are the possible drawbacks (aside from the cost of dry ice)? Dan Ritter <ritter at bitterroot.net> Ritter's MAMMOTH Brewery - Hamilton, Montana Return to table of contents

Would'nt the smaller proteins that get "passed on to the wort" help to increase mouthfeel and head retention in addition to reducing the amount of break material?

Date: Tue, 17 Mar 1998 09:40:18 -0500 From: "Spies, James" <Jams at mlis.state.md.us> Subject: foam control All - I noticed with interest the recent mini-thread about the use of the "foam control" stuff available throug HopTech. I used to regularly use this in my beers, especially the big ones, to control the amount of mess that I made with foam spewage through the airlock (I now use blow-off tubing). Anyway, the long and short of it is that, unless you've got a really small beer (OG ~ 1.035 or less), the effects of this stuff will be long gone by the time you drink it. I've also noticed that on some bigger beers (Belgian dubbel OG 1.087), the effects of the foam control seem to peter out after the gravity drops into the .040's, and the kraeusen springs up again. I've never had a problem with head retention using this, even on mid-level 1.040 beers, and it's useful especially if you have a smaller carboy. However, I would instead opt for the use of blow-off tubing. One final note - if you oxygenate using a stone, USE THIS STUFF. Adding it to the wort beforehand allows you to literally blast the hell out of the beer with O2 for as long as you want without having foam mountains rise out of the wort.
