I think we owe our guests and mentors, the honored men and women from the Siebel Institute, a grand round of applause...... To my mind, this has been unparalleled....the convergence of the best minds in the professional world of brewing with the best minds, and the most eager beginners, of the amateur brewing community.... To paraphrase Laurel Maney, I think that the world of professionals has been as impressed with the quality of thought from the homebrewing community, as the home brewing community has been with the quality of information that the pro's so freely give.... So, as a close to the Siebel participation in our world, I offer my thanks....You folks are the best...and doing what you have done...only proves it..... In conversation with Mr. Siebel, the door remains open for this to become an annual event....time will tell.... But some doors have to be shut eventually....and I suggest that any questions to the Digest for Siebel, that aren't posted by the Friday, May 28th edition, will simply have to be asked next year...if we haven't worn them out, and they agree to visit with us again..... But as far as I am concerned, we can not even begin to thank them enough... Rob Return to table of contents

Date: Wed, 26 May 1999 09:29:34 -0700 From: mike rose <mrose at ucr.campuscw.net> Subject: Malt flavor in beer >Kyle wants to achieve more malt flavor in his beer. Kyle, I have had this problem for some time. You probably have all the malt flavor, but you're probably lacking the mouthfeel that causes different flavors to be highlighted. The malt (or whatever flavor that I'm looking for) is dull and blended in my beers. I think it has to do with a lack of protein creating the proper mouthfeel and separation of the different flavors involved. I have seen several posts on this recently but haven't seen any solutions. I share your frustration, Mike Rose, mrose at ucr.campuscw.net Return to table of contents

Date: Wed, 26 May 1999 14:06:03 -0500 From: "WILLIAM R. SIEBEL" <SIEBELINSTITUTE at worldnet.att.net> Subject: Yeast strain's affect on head retention Hi Steve Jackson, Your question: Do different yeast strain's have an affect on head retention? Yeast strains per se do not have an affect on head retention. However, the growth characteristics of a yeast strain can affect foam. If a strain grows very vigorously, you may have unusual foaming in the fermenter. As you know, if you foam excessively in the fermenter, this is foaming potential that is lost. Additional yeast growth could also mean loss of bitterness units.The more yeast you have, the more of the bittering compounds will "stick" to the yeast and be lost as compounds to enhance foam. The last affect could be an early settling of the yeast, (finished fermentation, floc's out) and if you are treating this fermentation the same as a fermentation that may not be as rapid, some yeast autolysis may occur. This is obviously also bad news from a foam point of view. Yeast vitality ( or lack thereof) can have the same affect. If your yeast strain was not in very good shape, autolysis could occur, leading to poor foam. Choose a yeast strain that suits your purposes. Cheers, LYN KRUGER Return to table of contents
Date: Wed, 26 May 1999 14:13:41 -0500 From: "WILLIAM R. SIEBEL" <SIEBELINSTITUTE at worldnet.att.net> Subject: CO2 toxicity and it's relevance to small scale brewing Hi Mark Bayer, CO2 toxicity is not normally of concern in small scale brewing. But, bear in mind that this assumes that you are venting your fermentation vessels adequately and are not building up any back-pressure on your vessels. Back pressure on the vessel will increase dissolved CO2 levels. Another consideration is not to "cap" or "bung" the fermenter too soon in order to carbonate the beer. 1-2 Plato fermentable extract is plenty to carbonate your beer.If you are looking after these issues, CO2 toxicity should not be an issue. Happy Brewing, LYN KRUGER Return to table of contents
Date: Wed, 26 May 1999 14:30:02 -0500 From: "WILLIAM R. SIEBEL" <SIEBELINSTITUTE at worldnet.att.net> Subject: Yeast Questions Hi Stephen Alexander, Your list of questions would require my writing a book on the subject!! We have a lot of questions that we are trying to answer and unfortunately attempting to answer all your questions would require too much time and take up too much space on the forum. I will answer your first question. 1. Temperature vs ester You are correct when you point out that the information contained in W.Kunze, Technology og Brewing and Malting has some errors on pp 330-331. A classic way of increasing ester in a beer is to ferment at elevated temperatures. Ester production is influenced by: the amount of fusel alcohol, the amount of acyl CoA compounds and the activity of the enzyme(acyl alcohol transferase) that catalyzes ester production. Higher fermentaion temperatures stimulate enzyme activity and also increase (as with any chemical reaction) the reaction rate of ester production. I think that in any book (particularly if it has been translated ) there are bound to be a few typing errors or mistakes. You may have noticed another error on page 330. The ratio of higher alcohols to esters should normally be in the order of 3:1 NOT 1:3. Mistakes happen! I do not want to get too commercial, but if you want answers to the rest of your questions, you may consider taking our Advanced Microbiology Course (running in August) that covers all these aspects of yeast and fermentation and more!

Dan McConnell & Ken Schramm of the Ann Arbor Brewers Guild visited her a few years back in their search for Shaarbeek cherries. She did not have any, but she did provide Dan with some cherries from a Polish variety named something like Oblaschinska (spelling probably wrong!) She thought that this variety was probably the closest one that she had to what they were seeking. These cherries are almost black and intensely flavored. I've got a mead working with some of them in it (but haven't sampled it yet.) Dan made a pie with some and said that you could eat only a tiny slice at a time without overloading your mouth. Also, Hilltop Nurseries seems to have moved their web site, it's now at http://hilltopnurseries.com. I didn't see anything in their catalog that looked like it was close to Shaarbeek, but they do have a number of alternatives to Montmorency, anyway. =Spencer Thomas in Ann Arbor, MI (spencer at umich.edu) Return to table of contents
Date: Wed, 26 May 1999 16:52:42 EDT From: Radzan1000 at aol.com Subject: Siebel response to responses on position on HSA I apologize for my simplistic blow-off on the question concerning Hot Side Aeration. There have been some papers given on the dangers of hot side aeration, yes. Equipment manufacturers panicked and designed new systems to help eliminate this so-called problem. The industry cannot agree on whether it is a problem or not. The most educated and most technical minds in the industry cannot agree. Some major brewers claim it isn't and don't spend much time worrying about it. Some major brewers panic over it and have spent megabucks on elimination. Some major brewers use it as a stripping tool. The effects are hard to identify and measure. But we are all agreed that cold side aeration is detrimental to beer. We agree that air/oxygen must never come in contact with beer after the air/oxygen that we injected into the wort has been used up so quickly by the yeast. We can, and we do, identify and measure the effects of cold side aeration every day. We know and agree that it is so much more dangerous to the flavor and shelf stability of our product. Fermentation produces more than 1200 identified organic chemicals. Some of these when they become oxidized produce horrible flavors. If you would take the time and effort that some of you seem to spend on HSA, and redirect the time and effort to the elimination of air/oxygen from your product, you will be much better off. That is what I meant to say. That is what I should have said. Dave Radzanowski Return to table of contents

I would suggest that you reevaluate your technique. Even in a moldy environment you should be able to do sterile technique with a HEPA flowhood. If you have mold it is also likely you have other bugs in your cultures. Use of chemical agents (antifungals, antibiotics) is not a replacement for good sound technique. So go back an reevaluate how you are manipulating your cultures. Look out how you are preparing everything prior to starting to do things. Bring all the equipment and media to ambient temperature and wipe any condensation off all items. Then wipe everything down with a something like 70% isopropyl or a quat sanitizer. If need be work on a towel that is soaked in quat sanitizer and wringed out well. Wear latex or nitrile gloves if need be. Jim Liddil Return to table of contents
Date: Wed, 26 May 1999 17:23:32 -0500 From: "WILLIAM R. SIEBEL" <SIEBELINSTITUTE at worldnet.att.net> Subject: Pilot Brewery Questions Our 15 liter, five vessel, steam jacketed brewery was designed by some engineers at the Hamm's Brewery in St. Paul, MN sometime in the 60's. We have made some slight modifications to the system (incorporated a whirlpool vessel rather than the wort settling tank, increased the copper steam coils on both mash tun and kettle, incorporated a condensation collection system to measure evaporation rates etc.) but nothing to drastic. We typically realize a brewing material efficiency of 95%, however, during various research projects some that have taken the time, slow run-offs, have realized 98% - 100%. We measure efficiency by comparing the amount of extract that was available from the grist bill to the amount of extract that was collected in the fermenter. Sparging times vary, however, as a rule of thumb I always keep the grain bed covered with around an inch of water, and keep my total run-off time under two hours. Lake Michigan water is a great source of brewing water with slight modifications. My first concern is to remove any aromas (earthy, chlorine) from the water with a carbon filter. Next due to its' alkalinity, I acidify with a food grade acid (phosphoric). Lastly to increase the calcium level (Lake Michigan has about 33 ppm) I add gypsum or calcium chloride depending on what style of beer I brewing. Hop utilization is another calculation based on an analysis of a beers iso-alpha acid content compared to the amount of alpha acid present in the hops added to the kettle. I'm not familiar with the three methods mentioned in your question, but I will tell you how we calculate ours. 1 BU = 1 mg iso-alpha acid per liter of wort (sorry about the metric) 25 BU's would = 25 mg IAA/liter My brew size is 15 liters therefore: 15 liters x 25 mg IAA/liter = 375 mg IAA Next convert mg to grams by moving decimal three places to the left. 375 mg IAA = .375 g IAA Next I divide the required amount of IAA by my utilization which for my system is 30% .375 g IAA/.30 = 1.25 grams of IAA required for target 25 BU's Lastly divide the 1.25 grams IAA by the alpha acid content of the hop you decide to use for this beer. Say Saaz at an alpha acid content of 4.8% 1.25/.048 = 26 grams of Saaz at 4.8 % alpha. An lastly about the purity of liquid yeast cultures available to brewers. YOU GET WHAT YOU PAY FOR. AND MAYBE SOME THINGS YOU DIDN'T. High extracts & clear worts, Christopher Return to table of contents

Would the person interested in getting and propagating Schaarbeek cherries please get a hold of me. I was intrigued by your post so I put my Father (a retired farmer who lives in the Netherlands) and my Uncle (a landscape architect in Holland) on the case, both beer lovers which helps. I have some leads that may be interesting to you. TIA. <<< Please share with the group! I can't be the only person who cares. (I'm not the one who posted the question.) In that spirit, a gardening friend of a friend in Belgium said they were "Prunus cerasus L." According to my Sunset Western Gardening book, that narrows it down to any varietiy of pie cherries. I'm hoping for something more specific.>> Tim: First of all, if you travel through these parts, stop in New Glarus, Wisconsin and treat yourself to a New Glarus Brewing Co.'s 'Wisconsin Belgian Red'. It is an award winning Belgian style ale, with a great cherry taste. It is made with whole Door County (Wisconsin) Montmorency Cherries. This is the best of the two sour (pie) cherries that are commonly grown here in zone 4 and 5. They both are listed at my local nursery as: Prunus cerasus 'North Star' Prunus cerasus 'Semi Dwarf Montmorency' Fruit is red skinned and has yellow flesh. Both are self pollinating, with the fruit ripening in late July in Wisconsin. It is listed as a heavy bearing cherry, good for cooking, canning, freezing and eating. I am not sure of your growing locations and conditions, but the genus Prunus is susceptible to a number of fungal diseases. They need regular tending and are not a long lived fruit tree. If you have a local County Extension Agent in your area, they should have publications with details and growing recommendations for fruit trees.

I have always been extremely careful when handling carboys, especially full. On Sunday night, one slipped out of my hands, hit the sink, and shattered. The result: 14 stitches in my foot, 4 severed toe tendons (only 2 could be reconnected), and 3 weeks in a foot cast. Fortunately, it only had water in it (I was cleaning it). Be careful. Todd Cincinnati I am truly sorry to hear of your ordeal. I used to brew bare footed just cuz it was easier and more comfy than brewing with shoes or boots on. So twice now over the years I have slipped and shattered carboys with no ill effects......untill last summer when I was moving a 12 gallon batch of boiling hot wort to an elevated position to make use of gravity flow thru my chiller.... my foot slipped and the wort splashed onto my wrist and forearm and foot.... as the wort cooked my flesh for the eternity that it took me to slowly and carefully set the keg down safely. Then I went and rinsed my burns. I even finished the brew session before going to the ER with 2nd and some spots of 3rd degree burns. It took 5 weeks before all of the bandages came off and another 4 months before the colour came back and for the hairs to slowly come back. Brew carefull. Joe Return to table of contents
Date: Wed, 26 May 1999 22:05:52 -0500 From: Dean Fikar <dfikar at flash.net> Subject: Siebel: Break Removal After the boil in a converted Sanke keg I use an immersion chiller, whirlpool with a pump, and then drain from the bottom of the kettle through a SS pot scrubber covered with whole hops which seems to effectively create a coarse filter while pumping to the fermenter. The filtered chilled wort is slightly hazy but is otherwise pretty clear. For the lighter beer styles is this adequate or should I go the extra step and rack off the residual break into another fermenter a few hours after settling? Thanks, Dean Fikar - Ft.

I like this arrangement because I can be messy and hose the floor of the brewhouse out into the driveway and at the same time be relatively dry, clean and humidity free inside the fermentation room. The fermentation room also doubles as a cellar, and this would be difficult if I was heating the place up with mashing and boiling.

Date: Thu, 27 May 1999 08:01:56 -0400 From: "Philip J Wilcox" <pjwilcox at cmsenergy.com> Subject: Ebullometry Revisited Dear Siebel and HBDers, In wine analysis ebullometers usually come with a correction table for wines with high extract (1). Or in brewing terms high terminal gravity. Actually, extract in this context is measuring Total Disolved Solids. (Residual sugars, dextrins, tannins, acids, ect.) The corrections used is for every 1% extract (*P)you should reduce the ebullometrically determined alcohol level by 0.05%. A published table in (1 & 2) relates the gravity (*P) of the wine with the measured alcohol level to get the % extract. Knowing the % extract and applying the proper correction you get a more accurate measurement of alcohol % abv. Can this method be applied to beer analysis? And if so, how accurately? I feel that compared with wines, the differences in beer's lower alcohol levels and higher amounts of residual extract in --like sweet stouts, porters and doppel bocks--might produce a significant amount of error. At a minimum they are off the published charts Is anyone aware of such a corrections calibrated for beer? Or, has any research been done in this area? What say ye???? (1)Wine and Must Analysis by M.A. Amerine & C.S. Ough, John Wile and sons, 1974. The table with the nomograph for extract as a function of alcohol and starting Brix also occurs in several texts.

Enjoy your > sleep at night. This seems frightfully similar to something a less wise person (myself) has said many times. You might recall, that trying to grab this wiley invisable goon by the tail, I did a little 'spurment last year with "HSA". I split a batch and let half go flying throught the air at boiling temperatures, the other treated gently as pie. When mature, I sent them through a "triangle test" (a sort of standardised way to see if there is a perceptual differnence). Now I do a lot of these things, and it is frightening to see how things like: fermenter geometry, air space in a secondary, and sheer volumes of ferment can make perceptable difference in how fast the beer matures, and where it ends up.... simply frightening. I can't pretend to say that I've got a handle on most of these variables, just that they are variables worth paying attention to, and which my tasters can pick out. Sometimes I even just "switch kegs" between glass fillings without telling folks, and the more sharp palleted invarioubly notice: "Say, this one has a more pronounced hop flavour", even when what I have done differently within the batch can be quite subtle different fermenting conditions. Knowing this, I was quite careful to keep all other variables exactly the same for these two beers except the "kamikaze ride through the air". I have NEVER in a tasting had such a unanimous "Sorry, I can't find a difference" than I did with this one. One persom took a "guess" (admittedly) and was right, and then 6 in a row just had to say "sorry".... This meant that statistically I was going to have to have 10 people in a row walk throught the door and pick the right one before there was any "significant difference", and I decided I had better things to do. Apparently people who defend the "dreadful HSA" didn't, and my reporting of this waked not a small ammount of derision. George DePiro seemed most adament that "I must have done something wrong", and scrambled for imagined things that that could be. Now I am quite SURE that the people at Siebel are not interested in getting dragged into this most boring of debates, and I think Steve Alexander has unknowingly hit the nail right on the head... > These contest entry beer are often bottled with concern, but less control > over entrapped headspace air than in commercial practice.

You are already defining horrific conditions for beer, and the reason that most of us brew our own (to avoid subjecting the dear subject to such things, and allow a much more flexable introduction of "less stable" tastes). You are defining "commercial beer concerns", and this wakes whole mountains of categories that are relevant there, but not to someone who can take care of their product right to the very moment it is served. Quite frankly, I've no interest in "home brew contests", and when I've visited them, invarioubly find the "winners" taste like a "poor cousin" of a commercial sample that I've already spurned. > still sleeping uneasily, > Steve Alexander As well you may be, if you are shipping out your beer to places that are beyond your control..... you don't need to spread your insomnia. Perhaps the people who insist on propagating this worry, could just do a little "'spurmenting" on their own. I don't deny that the stuff exists (I've tasted these cardboard beers, but have no idea how the brewer managed to achieve them---- I never have, even with my primative intentional effort). If you did this, had say, an objective "triangle tasting" to evaluate, then you could say just "how much O2" and "how long an exposure time" and after "how much storage time" a percetable difference became apparent.(?) This, instead of bringing it up time and again in the most rediculous of circumstances, and always leading the conversation away from the tonnage of variables that never get discussed in any detail.

Dave Radzanowski reminded us that the best methods are the ones that work for us. And he also spoke from experience: "....the breweries that I worked for always introduced an amount of water into the mash vessel before the introduction of the grain....The grain addition is then somewhat rapid in the same time frame as the run in of the rest of the doughing in water...." This topic has been discussed here before, of course. I am brand new to all-grain brewing and contemplating a 180 F mash liquor temperature to make sure I hit 150-155 F, starting with room temperature malt and mash tun. With no experience, I worry about dumping grain into water this hot. Of course after heating the mash tun the system might only be 170F, but still pretty hot while adding the malt. If I use 180 F strike water, get all the malt in in under 10 minutes, and the temperature stabilizes at 150-155 F, do I need be concerned with denaturing the important enzymes? What are appropiate time windows to work in? Thanks for any insights Matt Comstock in Cincinnati _________________________________________________________ Do You Yahoo!?

I'm sure you now realize what a pandora's box has been opened. Anyhow.... There has been some discussion on the HBD in the past regarding the potential for fermenting lagers under pressure. The idea being that if you could control the pressure in a fermenter, you could actually ferment lager beers at much higher "ale" temperatures. Some homebrewers have done some "experiments" (thanks Jeff) that suggest it's not as easy as it sounds. Is it possible to successfully ferment a lager beer at higher temp and pressure without dramatically altering the flavor profile (i.e., tastes like a lager fermented too warm)? Thank you for your kind contributions. nathan in madison, wi Return to table of contents

These seem like >great potential sources for oxygen contact and HSA. Does anyone else recirculate this much? 50%!?! Man, sparging takes long enough as it is. One of the "happy accidents" I encountered when I tried a modified version of the Fix mashing regime (rest at 104F, add boiling water to bring up to saccrification), was that my initial run-off is stunningly clear. I'm not sure why, the only main difference is that my mash is much looser than normal. Recirculation on 1/4 to 1/2 gallon is all that is required. While I'm on that subject, my clarity also improved dramatically when I got my MaltMill (I previously used a Corona). I don't always agree with what Jack has to say on this forum, but he does make a fine mill. And no, I don't want to restart the "my mill is studlier than your mill debate." >Because of the lack of finish filtration (and often slower fermentation), >homebrewed beer in my experience is seldom in prime drinking shape in less >than one month and often requires 2-3 months before it hits it's peak for >clarity and flavor. As far as clarity goes--two words: Irish Moss. Is this really that difficult? As far as flavor goes, maybe I'm weird (OK, I _know_ I am) but I always like enjoying the flavor changes that occur in very young beer until it reaches it's theoretical peak. Not coincidentally, my beers usually don't make it to the third month. >A quick review of some modest gravity homebrewed ales >winning national prizes shows an age range of 3 to 9 months.

That's a rather large assumption to be basing a general truth on, isn't it? >These contest entry beer are often bottled with concern, but less control >over entrapped headspace air than in commercial practice. They are then >shipped cross-country with little or no temperature control. Here's the main issue in my mind. If you are a competition hound, then yes, you will need to be much more careful. Instantly the agitation, temperature, and other problems that arise with shipping suddenly apply to you. For 90% of the homebrew produced in this country, this is a non-issue. >still sleeping uneasily, Get some rest, Steve. This is one bogeyman that's not worth losing any over. Matt P.S. I hope this doesn't sound like a slam against Steve. I didn't mean it to be. He probably has forgotten more about brewing that I currently know. But I believe that HSA is one issue where homebrewers need to apply Charlie P.'s mantra. - ----- Webmaster, Green Bay Rackers Homebrewers' Club http://www.rackers.org info at rackers.org Return to table of contents

Date: Thu, 27 May 1999 12:05:31 -0700 (PDT) From: Steve Jackson <stvjackson at yahoo.com> Subject: Seibel: Decoction mashing My question concerns decoction mashing only for its impact on flavor. When decocting only for flavor affects, does it matter at what point in the mash regime the decoction is done (assuming a single decoction)? In other words, since the decoction is not being done in order to raise the mash temp from, say 135 to 154, is it crucial that the decoction take place before or after the sacc. rest? I mash in a converted picnic cooler, so increasing mash temps is not easily done (water additions work, but not precisely). I certainly do not want to spend much (actually, any) time in the proteinase range, so my options would be to decoct either following a beta glucanase/acid rest or after the sacc. rest. In the latter case, the decoction would bring the temp. up to mash-out temps. Am I "safe" in doing a decoction following my sacchirifcation rest? I'm assuming so, since one customarily pauses for such a rest before boiling the decoction, but I'd like to find a definitive answer.

We will be judging all 1998 BJCP beer, mead, and cider categories. This is an AHA sanctioned competition as well as a qualifying event for the Masters Championship of Amateur Brewing (MCAB) II (see http://www.hbd.org/mcab for more details). Points will also be awarded for Midwest Homebrewer of the Year. The main judging will start at 9:00 am on Saturday, June 12th. Standard AHA rules apply: we will need three unmarked 10-16 oz brown or green bottles, with bottle ID forms attached to each bottle with a rubber band, a completed entry/recipe form, and $6 for each of the first entry, $5 for each subsequent entry from the same brewer(s). Entries must arrive between MAY 26 and JUNE 5, 1999. We will accept walk-in entries from judges at 8:15 am on the day of the competition (June 12th) as long as the completed paperwork and fee arrive by June 5th. Our special category again this year will be the "No One Gets Out Alive High-Gravity Brew-Off". In this category, we will judge any beer with a starting gravity over 1.070 purely on the basis of drinkability and octane. For this category, we only require two unmarked 6-16 oz brown or green bottles. We will allow any high gravity style, but if you wish the beer to be also judged in another category, you must separately enter it in that category. No fortification is allowed. The winners in this category will not be eligible for best of show, but will receive a special award. Entries should be sent to: Boneyard Brew-Off c/o Piccadilly Beverage Shop 505 S. Neil St. Champaign, IL 61820 For additional information, contact the competition organizer Brian Paszkiet (bpaszkie at uiuc.edu or (217) 352-2438(H) or (217) 333-9033(W)). Forms and rules are also available on the World Wide Web at: http://www.uiuc.edu/ro/BUZZ/contest5.html Online entry and judge registration are available NOW.
