No boiling, no cavitational collapse but certainly >isomerisation was going on, you could taste it in the beer. It has been my experience (as a brewer ) that altitude, ie.. ambient atomspheric pressure does have an impact on the out come of a boil, especially hop utilizations. The lower the atmospheric pressure above the boiling surface of the wort the more rapid and efficient the isomerization will be, up to a point. Pressure reduction maybe natural (elevation change) or artifical (force venational). Expeimentation has shown that there is a cut off in improved hop utilization at a boil temperature of 103F (aprrox 7500 ft.) Interestingly your German friend seems to be going the opposite way with his concept of what is going on. As the old saying goes, every one in a pub is an expert on beer. In any event, a master brewer should be able to brew anything, anywhere, without excuses. Not boiling the wort at all is likely to have other, perhaps more interesting effects over time.

Anyone know anything about this? Translation below. The original is at http://www.bier-selbstgebraut.de/wwwforum/messages/395.html hallo leute ich hoere schon seit einiger zeit geruechte ueber neue braumethoden. es ist von brauen ohne malz nur mit gerste und sehr niedrigen energieaufwand mit gleichzeitig sehr guter qualitaet des bieres die rede. ich hab auch schon bier im handel gekauft mit dem vermerk "nach neuer braumethode" . wer kennt diese neuen methoden ??? Bitte um info === BEGIN === Hello people, I've been hearing for some time noises being made about a new brewing method. Something about brewing without malt and only with barley with very low energy requirements and at the same time with very good beer quality. I've also bought commercial beer with "according to the new brewing method" on the label.

Date: Mon, 23 Aug 1999 07:34:03 -0500 From: Louis Bonham <lkbonham at hypercon.com> Subject: Ice Brewing Hi folks: Contrary to conventional wisdom (as articulated by a few folks in today's HBD), the "ice-brewing" process actually *is* more than marketing hype. First, let's make sure we understand what "ice-brewing" (as that term is used by the big guys) actually is. It is *not* the process of concentrating the alcohol in the beer by dropping it to freezing temps and periodically removing the ice which forms. This process (used in producing eisbocks) is ancient, but is verboten in the US (at least for commercial brewers), as the BATF and most states treat it as a form of distillation which requires a distiller's permit. "Ice brewing," OTOH, refers to a specific process patented a few years ago. The process involves chilling the beer to about 30F, and racking the beer off the ice slurry just as it begins to form. By so doing, the alcohol is not materially concentrated (indeed, I believe that the big boys add a bit of water back to the beer so that the alcohol level is utterly unchanged). George Fix acted as an expert witness in a patent infringement case involving this patent, and is our resident expert on this subject. The benefit of the process, according to George, is that the ice traps a number of protein and other compounds that would normally drop out in extended lagering, and thus this process dramatically shortens the required lagering time. George gave a technical presentation on this at the MCAB in February, and says his split batch experiments demonstrate it does in fact produce significant beneficial effects for lagers. Perhaps if George has settled in in his new digs at Clemson he could comment a bit here . . . . . Louis K. Bonham Return to table of contents
Date: Mon, 23 Aug 1999 12:59:16 +0000 From: AJ <ajdel at mindspring.com> Subject: Acid Testing Jack S asks about acid test kits. The basis for the kit that you are using is that one milliequivalent(meq) of acid requires one milliequivalent of base to neutralize it. What's a milliequivalent of acid? For the purposes of this discussion it is 6.02E20 hydrogen ions. 0.2N sodium hydroxide contains 0.2 meq per milliliter so that if you put 15 mL (cc) of wine in a container and it takes 5 mL of 0.2N sodium hydroxide to neutralize it then the 15 mL of wine contained (0.2)(5) = 1 meq per 15 mL. If you dilute the wine with any reasonable volume of water you dilute the acidity but it's still 1 meq and it will still take 5 mL of sodium hydroxide to neutralize it. Thus it is the volume (or weight) of the sample that is important - not how much you dilute it in the course of making the measurement. The milliequivalent is a very fine unit of acidity but various industries can't seem to accept this and want their acidities expressed in terms of particular acids that are relevent to their industry. In brewing it's lactic, in the water industry it's carbonic and in the wine industry it's tartaric for the total and acetic for the volatile (also acetic for beer when beer volatile acids are measured). For cheese? Don't know. Expressing the acidity "as" one acid or another gives you a percentage value which would be the fractional weight of the particular acid based on the assumption that it is the only acid in the sample. Expressing acid "as" something requires multiplication by a factor which depends on the acid designated. and the weight or volume of the sample titrated. Thus if your kit reads percent as tartaric from a 15 mL sample of wine its factor is innapropriate for other volumes. It would be best, therefore, to use the milliequivalents (0.2 times the number of cc) and divide by the volume thus in the example above of 1 meq/15 mL report 1/15 meq/mL or 16.7 mEq/L. Using the same kit for milk with a 10 mL sample report x meq/10 mL or 100x meq/L. The last two questions... Both methods call for the same 3 drops of phenolphthalein. Why not 1 or 10 or why does not the amount of this effect the measurement. What is the relationship between t.a. and pH? ...are related. pH is merely a way of telling when the acid has been "neutralized". pH is a measure of the number of hydrogen ions in a solution. Low pH means high H+ concentration and high pH low (there is a reason for this). Neutral is defined in terms of water whose pH is 7. If you measured the pH of a wine sample with a meter you'd find the pH quite low (3? - I never drink wine) and as the NaOH is added during the titration you'd see it go up. The "end point" of the titration is when all the excess (over the number found in pure water) hydrogen ions have combined with OH- ions from the lye to form water. At this point the pH would be 7 and the acid would be said to be neutralized. Phenolpthalein has the property that it turns red at a pH of about 8.2. It is, thus, used in place of the pH meter (and as a laxative). It requires you to go a little past neutrality to get the color change but not very far so that the results are not very different from those that would be obtained with a pH meter titrating to true neutrality. In any event, the formal definition of total acidity is by titration to the phenolpthalein end point. If you use a pH meter instead of the indicator you would titrate to pH 8.2, not true neutrality (pH 7). As an aside, alkalinity of brewing water is defined in terms of a titration with acid to pH 4.3. As phenolpthalein is only a pH indicator the proper amount to use is just that amount that lets you see the color change easily. - -- A. J. deLange Numquam in dubio, saepe in errore.

Date: Mon, 23 Aug 1999 13:05:32 +0000 From: AJ <ajdel at mindspring.com> Subject: Ice Beer Can't agree with Eric Lande's asessment of ice beer. Ice beer is beer brewed by a patented process in which the fermented wort is brought to cold enough temperature that a bit of slush begins to form. This is removed thus pulling out some condensend polyphenols and some water. The beer is thus slightly more alcoholic and smoother. Have the patent in this clutter somewhere and will look for it if anyone is interested. - -- A. J. deLange Numquam in dubio, saepe in errore. Return to table of contents

Date: Mon, 23 Aug 1999 09:42:15 -0400 From: Marc Sedam <marc_sedam at unc.edu> Subject: [Fwd: ice brewing] A stronger version of bock called "Eisbock" was/is made in Germany by chilling the beer down to a slush and pulling off the ice crystals. Since alcohol freezes at a colder temperature than does water, a resulting increase in alcohol content (and corresponding decrease in overall volume) occurs. You can find more detailed information about this in "Bock" by Darrel Richman. There is a brewery in Canada, Niagara Falls Brewing (methinks), that still does this process once a year. Anecdotally, I've heard that the hella-megabreweries DO chill the beer down and skim off the ice...only to replace it with the same volume of water prior to packaging thus keeping the alcohol content and taste the same before and after the ice process. This process does shorten the lagering time somewhat (perhaps enough to be worth the extra processing cost?) as it's the most effective way to clear the beer (helps protein settle quicker??). Does it qualify as "Ice Brewed"? Well, Merriam-Webster says of brewing... Main Entry: brew Pronunciation: bru Function: verb Etymology: Middle English, from Old English brEowan; akin to Latin fervEre to boil -- more at BARM Date: before 12th century transitive senses 1 : to prepare (as beer or ale) by steeping, boiling, and fermentation or by infusion and fermentation 2 a : to bring about : FOMENT <brew trouble> b : CONTRIVE 3 : to prepare (as tea) by infusion in hot water intransitive senses 1 : to brew beer or ale 2 : to be in the process of forming <a storm is brewing> You could stretch English and say that it qualifies under the second intransitive definition, but seems to me that "brewing" traditionally has something to do with hot water. An oxymoron at best, brewing trouble at worst. ;-) Cheers! Marc Return to table of contents

Although Eric is correct that it is not a type per se. The technique involves high gravity lagers which are lagered below freezing. Over time, a layer of ice will form at the top of the fermenter. This (water) is removed, thus increasing the gravity of the beer.

I dont know, but marketing terms dont have to mean much at all. Sleazoid marketing of beer is not new and it will be interesting to see what new twisted phrases emerge in the coming years (how about Other folks will probably tell what "ice brewed" is (deeply chilled to precipitate out some smaller proteins due to filtering when slushy). High gravity brewing is a common technique among the majors because it yields more taste, but more importantly, it saves enormously on equipment capacity costs.

The problem is that the motor goes clockwise and the fan blade is counter-clockwise which results in the mash being pulled up from the bottom by the mixer. I don't think it really matters which way the mash circulates, as long as the mixing is througough and gentle. AC motors are not reversible.

Date: 23 Aug 1999 11:08:51 -0400 From: RCAYOT at solutia.com Subject: Dry Hopping and NEW Topic YEAST! Chaley Burns asks: "I've been aging this barleywine with an ounce of whole cascade on top for about a month now. Question is, at what point in time does it make sense to replace the hops with fresh ones? Assuming I want more and more hop aroma, at what point will all or nearly all of the aroma be extracted from the hops? 1 month? 2,3,??" I usually think about this in the inverted sense, that is how long must I keep the hops in to get any flavor? I think 1 week is barely minimal, two weeks seems to work okay, thre eor more is wonderful, I love the hop aroma from dry hopping. I would think that your one oounce is done, if there isn't enough hop aroma, flavor, then add more, you probably could have gotten more by adding more at the beginning, no need to go in steps. I also find that par-boiling hops - one or so ounces of hops one half cup or so water, bring to a boil covered, and transfer the whole thing to the carboy. I think I get a little less grassy flavor using this technique, but more importantly, I think the effect is more rapid. On to a new topic, how about Yeast! I would like to hear from people about the yeast they use, and the characteristics of the yeast, especially Ale yeast. I know thatt many people use Wyeast 1056, and I have too, but I really like some yeast character in my beer and 1056 is a little too clean for my taste. I have used Brewers Resources (no affil., yadda yadda) American Micro Ale #2 for some time, and I like it's fruity character, it also has very subtle diacetyl, although I am becoming so sensitive to diacetyl I am thinking about moving away from this yeast. Also, I would like to get some idea about yeast characteristics that don't necessarily come up in the promotional info. For instance this yeast throws up a really thick rocky head of yeast, a true top fermenter, makes for easy harvesting. Are there any other fruity yeasts out there that are also top fermenting? Anyone try the "Ringwood" yeast? What does it compare to? Is it available to homebrewers? Oh one more thing, a comment on the yeast lifetime discussion. I think I recalled something more like 6-8 buds as being more typical for a limit. In the information given that suggested 40 buds, was that in lab conditions with unlimited nutrients? I suspect that because critical cell wall components (sterol synthesis) are made with oxygen present, that there just won't be enough cell wall to go around for 40 generations. Another way of looking at it is: A broken leg may not be considered terminal, unless you have to chase down your dinner! Roger Ayotte Return to table of contents
Date: Mon, 23 Aug 1999 09:41:12 -0700 From: "Timmons, Frank" <Frank.Timmons at AlliedSignal.com> Subject: Re: Mash Mixer/Evaporative cooling Dana Edgell asks about reversing an ice cream mixer motor. Sorry, but on a small motor like the ice cream mixer motor, there is no way to reverse the rotation. Most single phase AC motors don't work that way. Some larger motors have dual windings, with a little panel allowing access to switch leads to the windings, but I doubt yours does. I would not advise trying to bend the fan blades, either. Fans are almost impossible to get in balance once the blades are bent. One of the best hints I ever got on cooling carboys in the summer was to use a Bundt-type cake pan (the ones with the hole in the middle) fill it with water and freeze it. remove it from the pan and set it on the neck of the carboy, and freeze another one. I go through one ring every 24 hours. the cold water runs down on a T-shirt, keeping it wet. Works great for me. Frank Timmons James River Homebrewers Richmond, Va. Return to table of contents

I'm not sure if this has been due to the "higher" temps that I ferment at(about 72F)/ wild yeast(fermenting all those "hard-to-fermentables")/or just letting it go too long. I thought that I had read somewhere that you could control the attenuation with temp. and pressure.(CO2) I tend to prefer my beers to have a nice FG instead of sporting the consistency of water!

Luckily, the assistant brewer was also a old time friend of mine, and I managed to get some information out of him on the recipe for their most excellent Extra Pale Ale. Here is what I could get out of him: during a 90 minute boil we have: at 30 minutes a charge of Eroica and Fuggle at 70 minutes a charge of Fuggle and Cascade at 80 minutes a charge of Cascade First of all, I've never seen additions of two different kinds of hops at the same time. Anyone have any info or experience on this? Second, Eroica hops are not all that prevalent in the recipes I've seen. Anyone tried 'em? Unfortunately, he wouldn't reveal the yeast strain. He rather cryptically said that the "secret to our beer is the yeast". Does anyone know what strain they use? I'll probably go with Wyeast 1056 for the first attempt, but it would be nice to use the real deal. Any information or recipes on Summit's Extra Pale Ale would be appreciated.

Date: Mon, 23 Aug 1999 13:09:49 -0500 From: "Christopher Farley" <chris at northernbrewer.com> Subject: Acid titration Jack Schmidling asks about acid testing kits: With a winemaking acid test kit you are performing a simple titration. The phenolphthalein is an indicator solution. It changes color at about pH 7, and it makes a great indicator solution. (It is also an extremely powerful laxative -- an old Chem prof described heinous practical jokes involving surreptitious additions to coffee.) The concentration of phenolphthalein should not make a huge difference; 3 drops should provide a high enough concentration for you to see a color change. When you are doing a titration, you are neutralizing all the acid in a sample. By carefully measuring the amount of the sample, and the amount and concentration of the neutralizer (1/5 normal NaOH), you can calculate the total acidity of the sample. This requires that you have a fairly accurate means of measuring volume (a syringe should be sufficient), and NaOH of known concentration. In my experience, the biggest cause of bad acid readings is people using an old vial of NaOH, because the concentration will change over time. Winemakers may add distilled water to a red wine prior to measurement because the pigment of the juice can make it very difficult to see the color change. Diluting a sample with distilled water will not affect the total acidity of the sample! Remember, you are neutralizing all the acid in the sample by reacting it with NaOH. The total acid of the sample remains unchanged even with added distilled water. I can't say why your cheesemaking kit calls for a lesser volume of milk. The acid testing kits we sell express the results in % tartaric acid. If you read British winemaking kits, they express acidity as % sulfuric acid. They use this standard even though sulfuric acid is not a normal constituent of wine, and should never be added to it. You might want to check your cheesemaking acid tester to determine which acid the results are expressed in. Christopher Farley Northern Brewer, Ltd.

Pat Babcock pretty much hit the nail on the head with: >T'was a friend whose father worked for A-B that told me it simply >was a means to reduce the "lagering cycle". The explanation was that by >"slushing" the beer, they expected that it would take much less time to >complete the lagering of the beer. Labatt actually patented the process of "ice brewing". In the text of the patent they claim that the formation of the ice crystals is a way to speed up the lagering process because the ice crystals form around "impurities" and then get filtered out. >The slight increase in alcohol was, to them, but a bonus. Actually, to avoid problems with the BATF the volume of ice crystals removed must be made back up with water (to within +/- 0.5% of the original volume).

I was called to the mat on my reply by Nathan Kanous. My assertion was that there really was no such thing as "Ice Brewed" and that is was a marketing gimmick. I was actually thinking of the Coors Lite ad calling their process "Frost Brewed". There are, of course, "Ice Beers" (Bud Ice, Molson Ice, Labbat Ice, etc.) circa early to mid 1990's. This is a technique that I believe originated in Germany with the first ice beer being an EisBock. Basically, the process takes the beer down to a temperature where the water in the beer freezes and the ice crystals are removed thus leaving a more potent and, arguably, smoother beer. I had an EisBock about a year or so ago and I thought that I should have been drinking it from a shot glass. Steven I don't know which process you were actually looking for, but here are both. Happy Brewing. Eric Lande Brewery to be named when I finish it Doylestown, PA Return to table of contents
Date: Mon, 23 Aug 1999 15:23:20 -0700 From: "Dana H. Edgell" <edgell at far-tech.com> Subject: Ice Brew The explanation I heard for ice beer/ice brewed is that after high gravity brewing the beer is chilled until ice crystals start to form. These crystal alledgedly form around complex molecules in the beer (like nucleation sites for bubbles). These molecules are then filtered out with the ice crystals. This is supposed to create a smoother tasting (blander) beer by removing the molecules (taste, body, ibus anything that might make the beer good). While the removal of the ice does make the high gravity beer a little stronger, the final alcohol level of the beer is determined as always by how much water is added to the beer at bottling. Idea that the ice removal makes "ice beer" stronger is marketing bs.

I pose... a question... to you, O all-knowing Oracle of Cyberspace... I use a counterflow wort chiller (CWC) and love it. Here in Maine, ever in the "heat" of summer, my well water is always ice-cold (almost) and chills my wort to frigidity as fast as it'll flow through. The question is... how the hell do you clean the damn thing? I've sifted through my books and mags (Z and BT's) and haven't found an authoritative recommendation on how best to do it. I've used the chiller for years, actually, and have lived in less-than-blissful ignorance by running 5 gals of boiling H2O through in before and after using it. This has served me pretty well, as rarely does a batch end up funked, and then I cannot say that it wasn't from some other source (faulty yeast starter, long lag time, carboy contamination, etc.) I must admit I've dabbled with running through some of the same boiling water with a few droppersful of phosphoric acid (reagent grade) or some unknown powerful alkali powder a friend gave me in it (some hydroxide of one sort or another), but obviously I don't know what I'm doing. The tubing is, of course, copper. My well-intentioned efforts and the fact that my beers taste good have given me no comfort...as GOD only knows what's growing inside that thing. So, my HBD colleagues, what'd you recommend as THE right cleaner/sanitizer?? MANY THANKS P.S. Oh, by the way, let me announce to alll the 8th Annual Northern New England Regional Homebrew Competition being held in Rockport, Maine on Sat. September 25th.

I didn't, much to my regret. I figured it would be in his new book, but that has apparently been held up by his more. Or maybe not. But now I've forgotten much of the specifics. Anyway, ice brewing is a real thing, according to George. It, as I recall, reduces lagering time and increases stability by removing certain size proteins, and, I think, some maltiness, but this last is a real QDA. I also recall that it is not used to increase alcohol content. There is a very small amount of ice actually produced in the commercial procedure. It seems that this is a procedure that is easily adapted to amateur scale. I was convinced enough of the advantages that I intended to use it. Anyone?

Date: Mon, 23 Aug 99 23:19:40 PDT From: "George De Piro" <gdepiro at fcc.net> Subject: speedy maturation / ice beer / licorice Hi all, There are many factors that effect beer maturation, and I do not understand them all that well. I have posted in the past about stuff Kunze and others have written on this topic, so searching the archives could be useful. At the brewpub, we have a need to get beer into condition quickly (to keep up with demand). I have found that one way to get beer to taste "done" quickly is to follow brewing practices that produce good tasting young beer. The better the young beer tastes, the less time it needs to age to become sellable. The following practices are all pretty obvious: Yeast selection and management are big factors. The gravity of the beer and other aspcets of the recipe will also effect how quickly it comes into condition. Pitching an adequate (or close to it) amount of healthy yeast is of paramount importance. Excessive yeast growth will lead to excessive higher alcohol production. These taste fruity, harsh, and solvent-like. They take a relatively long while to age out. Avoiding them in the first place is desirable. Providing adequate oxygen for the yeast at pitching time is a big part of getting a healthy, fast fermentation. If you can get the primary fermentation done in 4 days instead of 10, you now get 6 days of maturation without costing you extra time. Choosing the right yeast for your needs is another big factor. If you use a yeast that is a big sulphur producer (and yet don't want a lot of sulphur in your beer), it will take much longer to mature than if you used a low-sulphur strain. Lower gravity beers generally come into condition more quickly than higher gravity beers, and certain styles, such as Bavarian wheats, are drinkable at a very youthful age (the one I serve at the brewpub takes about 10 days from brewing to serving, and is peaking about 1-2 weeks after that, at which point it usually kicks and I start over again). Highly-hopped beers can take a while to smooth out, and if you are planning on dry-hopping you are adding 1-3 weeks to your maturation schedule. Most homebrewers don't have a problem with this, but if you were hoping to have a beer ready for a party two weeks from now, IPA may not be your best choice. As far as fermentation schedules go, keeping the temperatures as low as reasonable for the yeast you use will help produce a cleaner beer that requires less maturation time. My ales typically get pitched at about 60F, then ferment at ~64-66F, sit for a day or two at ~60F and then get chilled by 5F per day until they hit 35F or so. So far, the beers are almost maturing fast enough. If anybody out there has some other ideas, please share them! - ------------------------------------------------- Ice beer: I was surprised that nobody has yet mentioned the late Reichelbraeu Eisbock during the discussion about ice beers. Reichelbraeu was frozen and the ice removed to produce a very malty, alcoholic beer. Other beers, like EKU 28, are also frozen during production, but only to remove proteins (according to M. Jackson). Some, like the mega ice beers, are frozen and concentrated but then diluted back to their "normal" strength. I guess this will remove some proteins, but it does seem like more of a marketing gimmick (since there is so little to remove from Bud to begin with). Molsen XXX is an ice beer that is left concentrated, and tastes fairly gross because of it (very high esters and higher alcohols, but an extremely light body and flavor, other than the esters). - -------------------------------------- There has been some discusion about the presence (or lack thereof) in Old Peculier. AJ cites a drinking session in which he easily discerned a licorice taste in the beer while some of his drinking buddies did not. Ethyl hexanoate can be the answer! Ethyl hexaoate, an ester, is perceived by some as licorice (that's how I taste it), but is found to be more like apples by others. This explains several of the points in recent posts: 1. Only some people taste it. 2. The brewery denies the licorice addition. Fermentation conditions and yeast strain will greatly effect the level of ethyl hexanoate found in the beer. Granted, it does seem to be relatively rare (I have only tasted it once in years of homebrew judging), but it could be what's going on in OP. Have fun! George de Piro C.H.
