---------------------------------------------------------------------- Date: Mon, 09 Sep 2002 00:48:20 -0400 From: acez at mindspring.com Subject: Barleywine Fermentation Scott, If you had significant fermentation in the secondary, you probably have mostly C02 laying over the beer anyways, so it's most likely not much of an issue. If your still worried though, you can either use a clarifier or filter to clear it, then bottle, or you could transfer to a glass carboy flushed with carbon dioxide. If you fill a tertiary carboy with C02 very slowly, allowing the gas to sink to the bottom, then rack very carfully below it, it will expell any oxygen out of the top as the beer fills the carboy (for the most part), preventing significant oxidation. C02 is heavier than air and will layer like oil and water as it sinks. If you are having siphoning problems I would recommend checking out Fermetech's autosiphon available pretty much anywhere. Anyone who uses it (myself included) knows how much easier it makes the transfering process. The C02 process mentioned above will require investment in a C02 tank and a regulator, but if you decide to move into kegging (if you aren't aleady) you will be that much ahead. You can also buy C02 flushers that use little 12 gram C02 cartridges and save yourself some cash, but at the cost of turbulent expulsion into the carboy, requiring longer time to separate (I would imagine). Just my two cents. Good luck! Casey Return to table of contents

I bought in a supermarket a sixpack of the 6 vol% blond version on Friday 6, September (a 8.5 vol% brown version also exists). The crowncork mentions May 2004. My wife used to like this beer. But after a first sip she said, she didn't like this one. Color is a little darker than Pilsener beer. Foam is stable. The smell is a little sweet with some maltiness. Fruity ester flavors and aromas are moderate to strong. No diacetyl. Taste: first a little sweet, than fruity. Low bitterness, not lingering. The label mentions 6 vol% alcohol. Fermentation in the botlle. I measured 6 degrees Brix (with alcohol, so this doesn't tell a lot (FG approx. 1.024). In my opinion you can make this beer with Pale Malt (enough to get 6 vol% alcohol). Maybe a few % wheatmalt (5 %). Maybe with some sugar. I think the most important thing is the yeast. <http://www.trabel.com/brugge-ta-brouwerij.htm> <http://www.halvemaan.be/english/home.html> Greetings from Holland (Europe), Hans Aikema <http://www.hopbier.myweb.nl/> Return to table of contents

Date: Mon, 9 Sep 2002 08:35:00 -0400 From: Eric <edahlber at rochester.rr.com> Subject: Flandersweizen? I was hoping I could get some opinions (quickly of course) on what I should try with my latest brewing boo-boo. I have been brewing since January doing extract and specialty grain/extract. I have also been trying as many different styles as possible and recently fell in love with the few Hefeweizens I've had. My wife bought me the German Wheat Beer book from the classic beer style series and I decided to try the recipe for Hans' Hefe Weizen on p. 103. 4 lbs pale malt extract 4 lbs wheat malt extract Hallertauer hops (used pellets) 2.6 HBU 1.5 qts. Speise for priming Wyeast 3068 Weihenstephan Wheat Brewing went well except for the multiple boilovers (2 pots). I overshot my gravity a bit at 1.060, but figured I could water it down a little when bottling. I did notice the wort was considerably darker than I had expected Here's the problem (FINALLY KID GET ON WITH IT) I was using Muntons and Fines (light and wheat) extract and didn't realize that the wheat extract is only 55% wheat vs. the 100% I assumed. So I am nowhere near what I wanted and am probably even way past a Dunkelweizen. It's been in the primary 5 days and is starting to slow down.Then I get to thinking about the discounted (slightly old) pack of Wyeast lambic blend I saw at the brew store. So here's the probably lame and completely guessing plan -1) buy Lambic blend and 2) pitch into the speise I had reserved for priming. 3) wait a few days (weeks?) for Lambic critters to wake up etc. 4) rack beer and lambic speise onto maybe 5 pounds of cherries - Ta Daa - Flandersweizen in 6 months to a year? What do you think? My main concern was not being sure how well the slightly old Lambic blend might do up against a healthy supply of 3068. Is this blend hearty enough to catch up? Am I even close to a Flanders brown this way? I have only read 1 article (All about Beer march 2002) on this style. I picture - Clove, banana, cherry horseblanket -sounds good huh? Let me know - public or private - Eric Dahlberg p.s. I plan on dumping a fresh batch of Hans' Hefe onto the yeast left over when I rack Return to table of contents
Date: Mon, 9 Sep 2002 08:38:31 -0400 From: "Philip J Wilcox" <pjwilcox at cmsenergy.com> Subject: Re:Disolved Oxygen Research Demonick: Thanks fore your interest in my research. I will answer your questions as best I can. Unfortunately, I cannot carry out the experiment exactly as you requested. My D.O. meter is limited to 103 degrees F. Going to the boiling point of water would result in inaccurate results and possibly damage the oxygen-sensing probe. Oxygen content in water constantly decreases as the temperature decreases. It is an exponential relationship. That is, the rate of decrease is more or less constant (percent change/degree F) to about 170 degrees F. At about 170 degrees F the rate of decrease becomes even more rapid. At the boiling point of water no dissolved oxygen remains in solution. It might seem surprising that at the boiling point of water there is no oxygen in water. In "normal" exponential relationships the concentration gets less and less, but there is always some. As it happens, there is no solubility of the other major gases at the boiling point of water. I cannot say with certainty that there is some gas with limited solubility at the boiling point of water, but I doubt that any gases have any solubility at the boiling point of water. You may wonder why this is the case. As best I can determine it is due to that fact that one gas displaces another. For example, sparging water, beer, etc. with nitrogen will displace the oxygen, carbon dioxide, and trace gases. At the boiling point of water, water vapor is constantly being formed. Thus water becomes a gas and displaces other gases. I did boil some water and after it cooled to about 100 degrees F measured the dissolved oxygen. It was 0.82 ppm, which is about 8% of normal saturation. I feel that at the boiling point there was no oxygen left in solution. The conclusion is that the water cools, is picks up oxygen. It is doubtful, though, that the oxygen would return to saturation levels without considerable agitation or sparging with pure oxygen. I hope this answers your question. Good luck on your future endeavors. Phil DeVore ped at qdm.net Return to table of contents
Date: Mon, 09 Sep 2002 08:24:00 -0500 From: Mark Linton <cryptcl at earthlink.net> Subject: Diacetyl woes, can you help diagnose? Hi all, I just tasted my Bohemian Pils that I kegged about two weeks ago. Granted, it's not *really* ready yet, I'd like to give it a month or so to lager at refrigerator temps. However, couldn't help myself on Sunday and hooked it up to the tapper to pour out a half beer to assess its progress. I posted a question about this batch several weeks ago, when I was concerned about protein haze since I didn't do a protein rest with the Weissheimer Pils malt. I had just been drinking a Veltins pilsner, so the conversion on the palate should not be too extreme. At first, I thought I nailed it. The bitterness was dead-on compared to Veltins, but then the diacetyl reared its ugly head. Can anyone tell me the best way to avoid this in the future? I made a Munich Dunkel back in the Spring, and while it was good, there was some diacetyl in there that spoiled the party too. I've made other lagers, and never noticed them though. My method of brewing is the standard 2 x 5 gallon Rubbermaid coolers, generally using a single temp infusion (in the summer when I'm trying to speed things up), cool with an immersion chiller to the low 80's/high 70's, transfer to a carboy and leave it in the chest freezer until temps are down into the low 60's and dropping before pitching the yeast. I think I pitched the 1500 ml starter of the WLP802 Czech Budejovice Lager at about 60F, and it was in the low 50's just a few hours later. I'm pretty sure that the temp never rose above 54F, mostly residing in a tight range of 52-53F. White Labs claims "low diacetyl" in the description, so since I didn't do a diacetyl rest this time. Big mistake? I've done them in the past, but they just don't seem to do much - maybe I'm doing them at the wrong point of the initial fermentation. Too late in the process and the yeast has gone dormant, and too early and you'll probably *make* diacetyl, right? I'm wondering if I should pitch at around 50F, and ferment in the 40's F. Anyway, I'm perplexed why it happened this time, I thought I did everything right. Will this diminish with time, similar to the way sulphur goes away? Anything I can do now to improve this (otherwise) good batch? Attached below is the printout from ProMash, if that's of any help. Any guidance on any other item would be appreciated. Thanks!

Date: Mon, 09 Sep 2002 09:09:47 -0500 From: "The Artist Formerly Known As Kap'n Salty" <mikey at swampgas.com> Subject: re: Lager Starter Question Steve Spaketh in HBD 4036 =========================== > Hmmm - well I generally agree w/ the comments of Marc Sedam and > Kap'n Salty (Cap'n Crunch's evil twin) but let's take it a bit further. > I don't know what the DME+water formula gives, but starters should be > around 10P and not above 12P. Also the Kap'n says your starter is > too small but so is his. You should pitch 5gal of lager wort with the > yeast from at least a half-gallon starter and preferably a full gallon! A couple of clarifications here: - Kap'n Crunch is, in fact, _my_ evil twin. I mean the man is obviously a pirate -- do I really have to point this out? - As stated in my post, one quart for 5 gallons is the barest minimum, with at least a one gallon starter preferred. Again -- as stated in the post -- I personally use a 2 gallon starter (decanted, of course) per 6-gallon batch, or pitch on the cake from a previous batch, tho I generally don't pitch more than two subsequent beers on the same cake. It _is_ possible to make a decent lager from a quart starter, though I have had only mixed success with such a small volume, especially when pitched into a wort cooled to ferment temperature (in my case anywhere between about 44-48F). Problems that I've seen in the past include long lag times (always), underattenuation and less than clean ferments. On the other hand, I've also made the occasional decent beer this way. The bottom line though, is that a larger starter will yield _consistently_ better results, which is why I go to the trouble of making a large starter. As a rule, the bigger the starter the less problematic a cold ferment will be. In theory, it is possible to overpitch a beer, but in practice this would be pretty difficult. And remember: my results are SO good that Eric Fouch took one sip of my dunkel, wept, and declared he would never brew again. And he hasn't, to this day! - -- tafkaKs ==== Teleoperate a roving mobile robot from the web: http://www.swampgas.com/robotics/rover.html Return to table of contents
Date: Mon, 9 Sep 2002 08:02:43 -0700 (PDT) From: Carson Saunders <carson_saunders at yahoo.com> Subject: First batch -- question about fermentation I just brewed my first batch of beer this past weekend (Saturday) and I'm hooked already. I had a little bit of trouble cooling the wort down to the recommended 70 degrees (Im too cheap to buy a chiller). I pitched the yeast and put the fermenter in a closet. Later that evening I checked it and say that is was fermenting very vigorously. So vigorously that the airlock barely had time to "fall" after a bubble escaped before another bubble was ready to escape. Here is my problem. The very next morning (Sunday), I checked the fermenter again and noticed no activity. I thought it had slowed down and thought nothing of it. I checked again Sunday evening and still saw nothing. This time I sat and watched for at least 2 minutes and saw no bubbles. I also noticed condensation on the inside of the airlock. We keep the house at around 74 degrees and I don't think the closet is any warmer. Is this normal behavior or is something wrong? Thanks Carson Saunders Return to table of contents

Try pitching onto the yeast cake from a batch of APA or some such, using Nottingham or Chico yeast, and oxygenate often for the first 12 hours of the ferment. I'll sometimes toss an actively fermenting 2 quart starter after a few days in the primary. Open fermentation has worked well for me, too. I would suggest watching the temperature pretty carefully, as violent fermentations can throw off quite a bit of heat. I rack from the primary after about 2 weeks, rack again after a month or 2, bottle after another 2 months. Add fresh yeast when you bottle. Return to table of contents

They discovered that men and women who have consumed a moderate amount of alcohol find the faces of the opposite sex 25% more attractive than their sober counterparts. And the study revealed that there was no difference in the beer goggles effect between men and women. Students at Glasgow University were shown color photographs of 120 male and female St. Andrews University students aged 18 to 26. Participants were asked to rate their aesthetic properties on a scale of between one -- highly unattractive -- to seven -- highly attractive. Half of the students had drunk up to four units of alcohol, equivalent to two pints of beer or two-and-a-half glasses of wine. The 40 who had been drinking rated the people in the photographs as broadly more attractive than those not drinking. "Everyone`s heard of the beer goggles effect but we wanted to measure once and for all whether a moderate amount of alcohol increases the judgment of facial attractiveness," said Prof. Barry Jone of Glasgow University psychology department. "The increase in perceived attractiveness appeared to be the same for the ugly people as the pretty people, he said. "Attractiveness provides a very important signal of mate quality, it shows you have good genes and a healthy body." The beer goggles phenomenon is caused by alcohol stimulating the part of the human brain which is used to determine facial attractiveness, the nucleus accumbens, he said. Return to table of contents
