The title of this list is (at least as it has appeared on the last thousand or so HBD's that I've received) FORUM ON BEER, HOMEBREWING, AND RELATED ISSUES I'd say that a post on Beer in times past--in and outside the Bible or any other text--is on topic.

Date: Wed, 27 Jan 1999 09:30:13 -0500 From: "Penn, John" <John.Penn at jhuapl.edu> Subject: Defusing Those Bottle Bombs Well I was trying to bottle a couple of batches last night, a 6 gallon batch of Rocky Raccoon (Papazian) using Nottingham dry yeast, and a 4.5 gallon batch of Dubbel (Rajotte) using yeast salvaged from a Duvel bottle for a second time. Both had been in the fermenters for two weeks. The Rocky Raccoon dropped from an estimated 1.052 OG to 1.008 (measured 1.010 with priming sugar (5/8 cup honey) minus 2 pts for the sugar yields 1.008--same as previous batches of this recipe). The bottling of the Rocky went fine but when I went to measure my Dubbel which had an estimated OG of 1.070 and an expected FG in the low teens, the FG was a whopping 1.030 (1.032 - 2 pts for the 1/2 cup honey). Uh, Oh I said. I checked the hydrometer for air bubbles and took a second measurement, still 1.032. I couldn't believe the FG and I certainly couldn't bottle it. They would be overcarbonated about tenfold if I bottled now! So I quickly rinsed out my carboy from the Rocky Raccoon batch and siphoned the Dubble back into the fermenter for a couple more weeks. For extra insurance I pitched a pack of Munton's dry yeast on top of the fermenter. I couldn't aerate the beer and I didn't have a handy active yeast starter so I wasn't sure how healthy these dry yeast would be tossing them cold into a 5% abv beer (should have been 7% abv when done). At any rate I'm happy to say that there was about 1/2" of krausen this morning and about 1 bubble/4 secs in the airlock. Not sure what the flavor of dropping 40 pts with the Duvel yeast plus hopefully dropping another 15-20 pts with the Duvel/Muntons combination will taste like but I think it will be OK and mostly match the Duvel profile. The beer at the bottom of the bottling bucket tasted very sweet and thick confirming the high SG measurement. I checked my notes from the last batch I did using the yeast from the Duvel bottle and I had left it in the fermenter for three weeks. That was a rather tasty Belgian White (Sierra Blanca/Rajotte). The Duvel yeast seems to be a little slow in fermenting compared to say Nottingham but it stays fairly active for about a week both times and then slows down. The ferment temperature is in the low 60s so I guess I'll be OK if I just wait a couple of weeks. Never had this happen before, but then every yeast is different. 2 Responses to HBD Questions: Regarding the overattenuation question with Wyeast 1084, I seem to recall that it is not that great of an attenuator (maybe 65-70%). Maybe your batch is infected, I'd recheck your measurement and taste it for off tastes. Check the bottles at the top for a sign of infection too and let us know if you find out anything. Regarding the 48 hour lag time with not allowing your Wyeast smack pack to swell. Your beer may be OK, taste and time will tell. But the chances of allowing something besides the yeast to gain a foothold in your beer is increased during long lag times. The idea is to use a large yeast starter or lots of dry yeast and get into fermentation quickly. You want the yeasts to multiply and eat up the available food before the nasties get a foothold and once the yeasts start to convert the sugars into alcohol that tends to attenuate those undesirables also. If you are lucky you beer is fine, if not drink before it gets worse. Chances are better if you let your smack pack swell and pitch it into at least a quart or more starter. Rule of thumb is 5X step increase for lager yeasts and 10X for ale yeast. John Penn Eldersburg, MD Return to table of contents
Date: Wed, 27 Jan 1999 09:37:56 -0500 From: Dan Listermann <72723.1707 at compuserve.com> Subject: Blue Beer and Old Malt Syrup Spencer Thomas writes: <Blue color in veggies is usually produced by a pH-sensitive compound (sorry, I don't have the name at hand). Unfortunately for the prospect of making blue beer, it is reddish in an acidic environment, and requires a neutral or alkaline environment to turn blue. (QDA - Questionable Data Alert:) I don't know for sure that this is the same compound that makes blue corn blue.> <Unfortunately, beer is inherently acidic, so it seems unlikely that one could make blue beer using blue corn, or potatoes, or whatever.> Another data point. I found something called "Black Rice" in the oriental section one day and thought that it would be cool to make a "Swartz Budweiser." The bag said that the pigment was soluble. The mash took on a grape juice purple color, however the boiling of the wort destroyed this and the color was more amber than anything else. The only odd thing about the appearance of the beer was that the head had a slight pink cast to it. From: Michael Valencia <ranger at centuryinter.net> Subject: Old Malt Syrup <I opened an old jug of bulk malt syrup today only to find that the jug had a bit of mold around the cap and neck. Being in the brewing mood and not wanting to waste, I used the malt to brew anyway just for kicks. The question is, did I waste my time in using the syrup with some mold in it or will it be ok? I boiled for 1.5 hrs and added 2.5 oz of hops. Understand, did not want to waste this bulk jug because I still had about 22 lbs. of syrup from the 33 lb. jug.> I found an infected 33lb head pack in my store. It was inflating. I thought that I could throw it away or attempt to make something out of it and then decide whether or not to throw it away. The whole 33lbs went to make a 1.120 gravity barley wine - why not? When it was young it had an interesting Flemish brown horsyness which I enjoyed. However it seemed to disappear over time. I iced half of the batch it three times removing about half of the water. It is really nice. Dan Listermann dan at listermann.com Return to table of contents
Date: Wed, 27 Jan 1999 10:07:19 -0500 From: "Stephen Alexander" <steve-alexander at worldnet.att.net> Subject: dextrins/proteins/head/sweetness George DePiro back in #2930 and Scott Murman more recently takes up causes that I had been pushing last October Namely the contributions of protein to body and foam and the relative unimportance of residual dextrins. >It seems that far too many brewers (both pro and hobby) lose >sight of the fact that proteins are VERY important to body and >head retention. Producing a dextrinous wort is not going to >give the same effect as producing a wort with adequate levels >of foam and body-building proteins. I totally agree, but lets' not stop the iconoclasm there ... */ I am not aware of ANY commercial pale malt that deserves a sub 55C "protein rest". Generally you're just making thin unpalatable beer by resting at 45C-55C. */ Proteins and glycoproteins are primarily responsible for body/mouth-feel and foam. Similar HMW class of proteins involved are also responsible for haze. Haze vs body is a balance which *may* require higher temp (55C-60C) protein rests and/or fining techniques. */ Dextrins' major contribution to head+body is in that they add to viscosity more than alcohol (the alternative) and that this is a secondary effect for normal gravity beers. Making dextrinous beers is a crummy way to get body or head retention and should be left to Monks who otherwise fast during Lent. */ Dextrins are not directly responsible for "sweet" flavor profiles in beer. The flavor recognition threshold (point of perceptible sweetness) increases for increasingly larger sugar molecules) for maltose it's 0.080Mol/L (2.7P, 1.011SG). The dextrins (17%-27% of the extract) require yet higher concentrations in order to be recognized. So 15P of very dextrinous wort might give 4P of dextrins with a recognition threshold well above 4P. If you taste these at all it's as smaller sugar breakdown products that occur in the mouth. To expand on what Scott Murman says, caramels, certain peptides, esters, alcohols and even calcium ions are involved in sweet flavors. As they wrote in M&BS, vol 1, pp 269: "The caloric food value of beer is principally due to the ethanol and unfermented carbohydrates, but it is doubtful whether the latter contribute significantly to any other beer character, although glycoproteins may act as foam stabilizers". Mark Bayer adds that he want's malty flavors without sweet ones and wonders how ... As George pointed out, fermented wort is naturally sweet, but the balance of other flavors impacts the perception of sweetness. Decreasing hopping and decreases roast malt/black patent content increases perceived sweetness. Scott Murman correctly points to Maillard products, and melanoidins as the source of malty flavors but let me add that there are other heterocyclic compounds (molecules that appear as rings of carbon AND either oxygen or nitrogen) which are not the result of the classic strecker degradation and Maillard processes are also implicated in malty flavors. Maillard products - particularly those derived from leucine, isoleucine and valine are involved. The other heterocyclics are also probably the result of the same precursor molecules (sugars and amino acids) changing structure as they are heated. The heterocyclics include pyrazines, pyrrolines, pyradines. They are very much involved with nutty, malty and bread crust flavors. Some have flavor thresholds in the 0.1ppb range (!!!) and many are volatile (meaning select fresh malts). How do you control/increase these in your beer ? A lot was written in HBD about 2 years ago regarding Maillard products. These flavor products are likely to arise at temperatures from 80-150C and the mix and extent is temperature dependent. These can be formed during decoction and especially by pressure cooking wort. The non-maillard heterocyclics are most likely to form at yet higher temperatures and so are mostly controlled by the kilning of the malt. Selecting malts that contain these at the outset must certainly be considered. Munich and Vienna malts are obvious, but there is a big difference in the pale malts, which I suspect is due to final kilning temperatures. Kunze suggests very large proportions of "bruhmalt" can be used in some of the styles I've come to associate with maltiness - including dunkel(30%), marzen(20%), alt(50%). If I knew where to get my hands on European bruhmalt I'd try it. Oddly yeast seem to have a big impact on an aspect of flavor that is sometimes called maltiness. To my mind this is different than aromatic maltiness, but I'm not sure that I can characterize the flavor any better than that. Yeast choice matters when it comes to malty character.

Date: Wed, 27 Jan 1999 09:26:44 -0500 From: Bill Jankowski <wjankowski at snet.net> Subject: Natural Carbonation in Kegs I haven't stepped up to kegging my beers yet, so I may be way out to lunch. If so, please forgive. But, if the problem with natural carbonation in kegs is having the CO2 leak out through the seal around access port in the top of the keg, could inverting the keg during carbonation use the beer to provide a seal? Gaskets tend to seal better when exposed to liquid instead of gas, and the weight of 5 gal of beer (~40 lbs) might help it seat as well. Granted, this brings up problems with having the yeast settle out on the top of the keg, but a brisk shake a day before serving would give it plenty of time to settle out.

A bag of 2-row malt that I had not yet used started to grow mold on th outside of the bag. I opened it this past weekend and found out the mold was also on the inside of the bag. When I transfered the malt to 5 gallon buckets for storage I noticed the malt on the perimeter of the bag also had mold on it. My first thought was just to throw it all out. Then I thought maybe it can be washed off before crushing, however I really don't want to to spend a brew day making bad beer from bad ingredients. Does anyone have experience with malt that has had some mold on it? TIA Kevin Brown Brewing on a Virgin Way south and east of Jeff Renner Return to table of contents
Date: Wed, 27 Jan 1999 09:39:05 -0600 From: Vachom <MVachow at newman.k12.la.us> Subject: eating crow, qualified I'll step up to the plate here and remind the assembled that I was one who made apocalyptic predictions for Jeremy's steam beer--the one in which he pitched an un-inflated smack pack of Wyeast 2112 on the advice of his brew supply shop owner. I further advised him not only to be suspect of this person's advice but to consider frequenting another supply shop. Even more, I'll confess that I dispensed this advice having never pitched an un-inflated smack-pack myself. The problem here is, in principle at least, the point Dick Dunn is trying to make. Passion and science are necessary but dangerous partners. The former can inspire absolutism, posturing, and uninformed generalization, pretty much the top three enemies of science. Without passion, however, science is a hollow and potentially static enterprise. That said, I'll qualify my advice to Jeremy. I should have said that whereas it's entirely possible his beer might begin fermenting, I do know that I've gotten much shorter lag times and consistently better beer from waiting for inflation, building a starter and pitching. With hindsight, now, I can say to Jeremy that the 48 hours it took his beer to begin fermenting is a long lag time, time enough for flavor-affecting bacteria to take over. We would all do well to remember on occasion that underpitched batch like Jeremy's or the one the baby puked in that was far better than any subsequent attempt at the same recipe during which every procedure came off like clock-work. . . .or to recall Danny Murtaugh's words: "Why certainly I'd like to have a fellow who hits a home run every time at bat, who strikes out every opposing batter when he's pitching, and who is always thinking about two innings ahead. The only problem is to get him to put down his cup of beer, come down out of the stands and do those things." Mike New Orleans, LA Return to table of contents

Date: Wed, 27 Jan 1999 11:11:21 -0500 From: Andrew Stavrolakis <andrew_stavrolakis at harvard.edu> Subject: Ipswich Ale John Doherty asks in HBD: "Does anyone have any information regarding of the yeast strain used in Ipswich (MA) Ales?" The yeast is Wyeast 1028 London Ale. The folks at the brewery feel there are "house flavors" that may not be duplicated at home if using this yeast, however I have had excellent results. The grain bill is mostly pale ale with a touch of crystal 40 for color (I would guess no more than 5%). The hops are Willamette. "Furthermore, has anyone personally cultured said yeast from a growler or bottle?" I haven't personally, but have heard of many who have. "And lastly, has anyone heard rumors of the sale of Ipswich Brewing Company? After recently noticing a big drop in the amount of Ipswich in stores, I've heard from one source that Ipswich had temporarily ceased operations in order to complete their sale to a larger entity. I'm told that they will soon resume production of their full line of beers on an even grander scale, but my details are frighteningly sketchy at best." I haven't heard these rumors. I haven't noticed any lessening of it's availability where I shop. On the other hand, I currently have so much homebrew available that I haven't bought any in probably a month. It has been available in six packs as well as growlers for at least a year. Ipswich Ale in my opinion is one of the finest pale ales available in this (Boston) area, and I would be very disappointed if this business decision manifests itself in poorer quality beer. However, if it means more great beer for the masses at a lower price, then more power to them. Alas, it will probably be something in between.

Eric I hesitate to write because this is obviously a subject you feel strongly about, but I suggest you are wrong. HBD is about beer in general and related subjects [like whisky yeast ;-)], especially when traffic is low, as it is now. One of the great things about HBD is the broad range of expertise available in the members, ranging from microbiology, engineering, refrigeration, and now, biblical history. When someone makes a dubious assertion (or Spencer's new acronym QDA - Questionable Data Alert), someone is sure to correct it. This is what happened. I was glad to have an expert refute what were obviously (to me) bad assertions. The fact that you don't want to hear about it doesn't make the posting of it wrong. A lot of evil has been done in this world in the name of religion, as you no doubt are aware. Today in the US, especially, many use it to promulgate intolerance and bigotry of the worst sort. Perhaps it is this that has made it such a sensitive issue for you. I obviously don't know. But it doesn't make it an off limits subject when it relates to beer, as this did. >While I realize most subscribers have careers other than brewing, >wouldn't it be better to leave this forum as it is?

Been there. Jeez, what a hobby. He also writes: "I am brewing a steam beer using wyeast California lager yeast at ale temperatures (currently 70 deg) which I plan to rack off to a secondary in a few days and cool to 50 deg." Is a secondary necessary, and is 'lagering' at 50 necessary? Or can the 'Steam beer' just be worked up like another ale, but using lager yeast? For that matter, consider the two scenarios with the same batch of ale: 1. In the primary two weeks, then bottled 2. In the primary 4 days, in the secondary 10 days, then bottled. What differences would you expect - what would I gain from using a secondary. How long is too long in the primary - when does autolysis really start to be a problem? I could argue that transferring/siphoning and the use of another container (that required sanitation) would lead to oxidation and infection problems. I think I've seen AlK defending the practice of just using primaries, and should check the archives, but.... Hey, where is AlK.

I have been reading the HBD since I began planning this project, and have learned quite a bit from the posts and links provided by some of you in your messages. Thank you all for the great information. My research and the many posts I've read have led to a few questions and I figured this is the best place to find the answers, so ... 2 questions (for now): 1- When using brass fixtures in my brewery does cleaning them with a 2:1 ratio of vinegar & hydrogen peroxide one time before installing them eliminate the danger of lead leaching into my brew forever, or does this cleaning process need to be repeated? 2- When building a bulkhead to attach plumbing to a HLT or a mash tun, will any rubber washers work well (not effect flavor), and are Zinc washers safe to use?

Date: Wed, 27 Jan 1999 12:24:40 -0500 From: Jeff Renner <nerenner at umich.edu> Subject: CAP update Brewers Interest in Classic American Pilsner (CAP) has really taken a jump, based on the number of emails I get on it. I think it is time for an update of my original article in Brewing Techniques http://brewingtechniques.com/library/backissues/issue3.5/renner.html (which was a rewritten HBD post and was inspired by BT articles by Jankowski and Fix). Since then I have learned lots and have modified some techniquwes, although the original recipe will still make a great beer. This is a first, very rough draft of what I will be working up for a BT update. I welcome discussion. There are a few basics as I see it: Base malt - US 2-row or 6-row, which is historic but Fix recently reported (HBD?) prefering 2-row as producing a more refined product. I've never used it in a CAP, but I certainly like my results with 6-row. I use a little Munich (~5%) if I'm not doing a cereal mash, and some people like a similar amount of carapils. Adjuncts - Corn is my first choice, although I'm going to use rice next time just for the experience (but I prefer corn based on tasting others). Some breweries (Rolling Rock is one) use both. If you use flakes, there is no need to pre-cook. If you use corn meal/flaked/polenta or coarsely ground rice, you need to cook first, and I like to do a short mash with 30% malt first as you have no doubt been reading about in HBD. I use 22% corn meal these days. I think you need at least 20% to really make it a CAP and I'd like to keep it under 30%. If you use flakes, smell them to be sure they're fresh. This can be a low turnover item in shops and get stale. Mash schedule - a step mash was traditional (see Wahl and Henius http://hubris.engin.umich.edu:8080/Wahl/), but it isn't necessary. You can do a straight infusion mash with flaked corn or cooled cooked raw corn/rice. Lately I have been using a step mash by boosting with a propane burner and recirculation - 40C mashing, boost to 55C, add cereal mash and heat if necessary to bring to 65, rest 30 minutes, then boost to 70 and rest for 20-30 minutes. The 65/70 rests seems to give me a slightly more attenuated and drier beer than the 60/70 I used before. Hops - Cluster is the only hop still available that we think was used in pre-pro days. It certainly was used by the 1940's, although it may be somewhat different now. Someone with access to hop history needs to look into this. The historic recipes I have seen only differentiate between "domestic" and "imported" hops. I certainly like to use Cluster for bittering. I think it's an important part of the style. There isn't much remaining actual flavor after a boil. I use noble hops, usually Hallertauer of some sort, for first wort hopping (FWH see http://hbd.org/~ddraper/beer.html) and finishing hops. Historic recipes used both domestic and imported late addition hops. I'm not aware of American records of FWH in preprohibition, but Fix reports that it was used in Germany at that time, and there was a great deal of German influence on American brewing. I FWHed once with Cluster and very much disliked the result. The "black currant" or "American" flavor of Cluster predominated in a most unpleasant way, almost like a berry beer. Bitterness - My original recipe used 25 IBU and no FWH. My standard beer now is FWH and ~35 IBU taking into account the FWH contribution. See Jankowski http://brewingtechniques.com/library/backissues/issue2.1/jankowski.html for some historic data on 1950's New York beers' bitterness. Gravity - It seems that pre-pro beers may have been stronger than post, but perhaps not so much as legend has it. See Fix http://brewingtechniques.com/library/backissues/issue2.3/fix.html. I will research this more. I find that I like 1.048 for a drinking CAP. Yeast - Any lager yeast should work, but friends have had diacetyl with Anheuser/Busch Wyeast (Wyeast 2007/ YeastLab L34) and California Common (Wyeast 2112/ YeastLab L35). I used New Ulm in my original (Wyeast American) and despite Wyeast's note that it is not a pilsner yeast, I liked it fine. The old Christian Schmidt (Philadelphia) yeast is reputedly Wyeast 2272. I really like Weihenstephan 34/70 (Wyeast 2124, YeastLab L31) as a good general purpose lager. I used Danish (Wyeast 2042) yeastss ago for all malt Northen European lagers and very much liked the crisp, hop empahsized profile it gave, and think it would do well for a CAP. My current favorite lager yeast is Ayinger from Yeast Culture Kit Co. (http://oeonline.com/~pbabcock/yckco/yckcotbl.html). See Scott Murman's yeast page at http://www.best.com/~smurman/zymurgy/yeast.html for more information on yeasts.

You should always use a starter. - AND - The majority of responses that you will get from readers of the HBD will also be wrong. Especially the ones that indicate that you WILL experience dire results or that your beer WILL be ruined. Your beer MAY be ruined but, many people have made excellent beer by just pitching a smak pak without a starter. It is not a good idea and I do not recommend it, but people do it all the time and it can make excellent beer. >My fermentation has been so vigorous that I have been unable to keep a >fermentation lock on.

Physicswise I don't see >much difference between this setup and an airlock anyway. Let*s see if we can jump to another all too typical HBD opinion: *Your beer is ruined. Obviously, the activity you are observing is the result of an infection that was picked up during an abnormally long lag phase. I would dump it if I were you.* >Am I out in left field? No, keep brewing and do not worry. See what happens to your beer this time, take notes, and then decide if you need to adjust your methods nest time. - --------------------------------------------- Dick writes: >Of what value is "a good thought or suggestion" if it has no support? >We don't need a reference, specifically.

Despite what a few ego-maniacal, over-aggressive, frequent posters believe in there own minds, the HBD is NOT a scientific journal or forum. At best, it approaches it at some times. What if you are simply relying on experience and do not have any *references* to back yourself up? You are then left to throwing in a lot phrases like: *Based on my 10 years of brewing experience.......*, or *when I was at Seible.....*, or *while working on my Ph.D. in yeast mutation theory at MIT.....*. All of which is a big turn-off to the majority of HBD subscribers who are regular, working class (and some professionals) people who like to drink and brew there own beer. I for one do not want to keep reminding people that I have been brewing since 1985, have a college degree in engineering (from a well respected, accredited university), and have a very sophisticated sense of taste. (eeew, see how pompous that sounds?). Besides, having worked for a long while in the consulting business, if I really wanted to use references, I guarantee that I can come up with a reference to support my point of few on any subject, no matter how obscure it is.

Well put! There far too many opinions stating that if you do X you will get Y. (If you have a fru*tf*y you WILL have bad beer, if you under -pitch you WILL have bad beer, ect.). The real world just does not work that way. Brew on Paul Niebergall Return to table of contents
Date: Wed, 27 Jan 1999 10:54:13 -0800 From: Alan Dowdy <Alan at Auroracorp.com> Subject: Filtering beer Question(s): I tried using my cornie as a secondary and found that while the beer turned out pretty good(IMHO), it had a lot of chunks(trub?) floating in it. I figured this was a good excuse to experiment with filtering and purchased a the stuff needed to connect a filter between two kegs. I tried it by connecting it between the two kegs, setting the regulator to about 7 psi, and opening the pressure relief valve in the second keg as necessary to keep the beer flowing. What came out to the filter was nothing but foam. Fortunately, I had already consumed at least a third of the keg(chunks and all), otherwise I am afraid that I would have lost a lot of beer to foam shooting out of the relief valve. Is my procedure wrong? Is all the foaming normal? Thanks for your help. Alan Dowdy Torrance, CA(no idea how far from Jeff) Return to table of contents
