---------------------------------------------------------------------- Date: Thu, 07 Jan 1999 19:57:03 From: william macher <macher at telerama.lm.com> Subject: Steam and cooler wall damage potential HI all, In HBD 2920 Jon Sandlin asks whether steam will melt his rectangular cooler...and if CPCV is an OK choice for a steam injection manifold. If your steam source is a pressure cooker (with all safety devices still in operation), and you are feeding the steam directly into the mash tun without further heating, then the steam temperature will be a bit higher than the boiling point of water at your elevation. This is because there is some back pressure in the steam line. It will not be that much higher than the temperature of boiling water though. The actual temperature will depend upon the back pressure and the temperature loss as the steam proceeds down the tubing from the pressure cooker to the mash tun. It is important to remember that when injecting steam into the mash tun one must do something to keep from overheating the mash in spots. In other words, continuous mixing of the mash is necessary while the steam is being injected. The steam will not bubble up through the mash and disperse evenly. It will condense at the injection point and raise the grain temperature in the area of injection to the boiling point if continuous mixing of the mash is not done. Just a review for new potential users of steam... as I understand them...:-) If you position your manifold in the plastic mash tun so there is some space between it and the plastic surface of the tun, and you stir continuously while injection is occurring, it is likely you will not damage the floor or walls of the cooler if they are able to withstand the normal mash temperatures you currently use. The real answer depends on the temperature rating of the plastic the cooler is made from. Is this specification available? Probably not. If the rating were about 220F you would likely not have a problem even in the worst case scenario... As to whether a CPVC manifold will work for steam injection...Maximum temperature rating of CPVC pipe in one catalog I have is 180 F. Another catalog has high temperature CPVC rated to 212F. This is a specialty item and something you probably do not have. Since the steam will likely be between 212 and 220 F, CPVC would not be a good choice for a steam-injection manifold. RobertJ's <pbsys at pbsbeer.com> recommendation: >You may have a problem with the CPVC softening. PVC melts >(softens at about 140F). I think CPVC does the same at about 170F. >I suspect you'd be better off if you make your >manifold from copper is a good one. Fabricating a copper manifold is probably the best solution.

Jokingly someone asked me if I knew where he could get some fruit flies for his starter because they were rather scarce in his climate. I answered with some off the wall joke and we had a good laugh. WELLLLLL ! ! ! Guess what I found.. A company that actually sells them. Check it out, seriously. http://drosophila.herpetology.com/work.html These are Drosphilia Melanogaster and Hydei Sturdivant, two types of fruit fly, shipped to your door. They are shipped as eggs in a medium that keeps making more and more flies. They are genetic mutants and can't fly, they just hop. They are meant to be food for herps (you know, snakes, frogs, lizards, etc) But we all know that they belong in yeast starters, don't we. Just kidding. The site is real though.

Beer, they say, may protect against certain carcinogens that are produced in food when it is cooked. Japanese sake, red and white wines, and brandy were also effective, but whiskey was not, nor was ethyl alcohol in the concentration found in beer. The researchers conclude that something in beer, possibly the hops, the plant phenols or some other component yet to be discovered, are responsible for the popular drink's apparent anticarcinogenic powers. . . . . . . . . . . . . . . . . . .

"I must preface this with the fact that I am not a customer of St. Pats, nor am I affiliated with them in any way. But, I find this lack of respect to customers to be terrible.... Frankly I find your comments and Lynn's response a perfect non sequitar. The complaining letter was a bridge burner from beginning to end and her response was about as patient, explanatory and dignified as one would expect. I have heard many complaints about Lynn's treatment of customers but this is the first I have seen spelled out and I now understand the problem. Cliches aside, the customer is frequently wrong and only the best of sales people are able to keep their cool. You folks just have no idea what happens to this business around Christmas time and how we sometimes feel when we have to take out time from producing product explain to phone callers that we can not ship a mill so Honey can have it under the Christmas tree or a dozen to a dealer who should have ordered months ago.

Date: Thu, 07 Jan 1999 23:39:10 -0500 From: Rod Prather <rodpr at iquest.net> Subject: Thank to all. Boy was I red! Thanks to all for the comment on my turning red. I think I have it under control. I got a ton of responses and I know I didn't answer most of them. Several of you mentioned alcohol flush or some reaction to alcohol. My ABV is around 5%, and I've never had the situation with any other alcoholic beverage. I drank a Bass Ale and a Sam Adams later that night with no reaction. I think Robert Waddell may have hit it. It is highly possible that I produced some fusel alcohols in the early fermentation. The beer is very young. I'll let it sit in the secondary for 4 or 5 days then bottle it. I'll let everybody know if it changes. The other possibility is hopping. I think the IBU is quite a bit higher than I planned. The hop tea may have extracted some chemicals I'm not used to. If it is the hops, which I doubt, the final product will have the same affect. Return to table of contents
Date: Fri, 08 Jan 1999 06:47:14 +0000 From: AJ <ajdel at mindspring.com> Subject: Beer Color Lars Bjornstad had some comments and observations on beer color. What a fascinating subject! Unfortunately, its also a complex one if any degree of precision is required. Perception of color depends on lots of things such as the physical properties of the beer in particular the relative degree to which light passing through the beer is absorbed at different wavelengths which in turn depends on the length of the path through the beer as well as its chemical makeup. Also in the physical domain in the spectral energy distribution of the light source. But color perception is actually a psychological thing and the measurement and description of color represents a near unique marriage between the arts of the engineer and the psychologist. Perceived color depends on the particular individual (extreme outliers are persons who are "color blind"), on other colors in the visual field (background) , the size of the colored object being observed and and the color of other things which the observer has been looking at recently (adaption). Thus determination of beer color by observation is iffy and brewers have tried to come up with instrumental methods not subject to the shortcomings of the flesh. The ASBC method is based on experiments done about 50 years ago with 34 American and Canadian light beers (the darkest was about 5.97 SRM !). The spectral absorbtion is measured at a wavelength at which the beer absorbs a lot of light (430 nm). Another measurement is taken at 700 nm. If the ratio of the absorbtions at the two wavelengths is too small the sample is considered either atypical or turbid and the SRM value is considered invalid. It is not surprising given the foregoing that the SRM method (and similar EBC method) have some limitations. The worst flaw in my opinion is that one finds beer pairs in which the lighter appearing beer has the higher SRM value. Even with it's limitations the SRM scale is surprisingly good at telling you how light or dark a beer is when viewed via transmitted light in a glass of average diameter (5 cm). SRM correlates quite well with the so called CIE Luminance. If I plot SRM vs CIE luminance of a 5 cm sample (light quality: CIE illuminant C - another detail which must be specified) of beer (sample size: 65 beers) and fit a straight line to it the agreement is quite good. With a little scaling and offset I can obtain a "pseudoSRM", as I call it, which is quite close to the actual SRM value (for example Lars's post cited Guiness as having an SRM of 65 which I measure at 61.5 giving a pseudoSRM of 69.3). The pseudoSRM values do not ever assign higher values to lighter beers. By adding two additional meaurements (the CIE chrominace values) we have a complete discription of the actual color of the beer. For Guiness these values are x = .7190, y = .2180 which can be transformed into other terms which say that the color of Guiness is red (dominant wavelength of 640.2 nm) and 99.9% pure (highly saturated). This statement evokes surprise (and sometimes outrage) but anyone who is either surprised or outraged should pour some Guiness in a glass of about 5 cm diameter and shine a penlight throught it. It is a beautiful deep, pure red (as are all beers if the path is long enough). But it doesn't look red when they set the glass in front of you, does it? It looks black as you typically see it (mostly by reflected light) and so all this about 5 cm depth, illuminant C etc. is pretty meaningless except in a laboratory setting or unless you always drink your beer in a 5 cm glass and always look at it while holding it up to the light. I do advocate use of the CIE system for description of beer color simply because so many other industries use it, because it is not befuddled by beers with weird (compared to the 34 standard) spectral distributions (try to measure SRM on a Kriek) because it gives a complete color description rather than just a light/dark indication and because it is measured using the same instrument that is used to measure SRM. But it has its shortcomings. But you know, now that I think of it, I haven't had any calls from the ASBC, MBAA, EBC or any other organization soliciting my opinion on this.

Date: Fri, 08 Jan 1999 07:54:54 -0600 From: Nathan Kanous <nlkanous at pharmacy.wisc.edu> Subject: Cleaning Phil's Chiller Greetings everyone. I've got a friend that is concerned about his new CF chiller. Seems he's had a couple of batches go south on him since he started using it. He's concerned about sanitation. I usually just run a gallon or two of "near" boiling water through mine after I'm done chilling the wort. Turn it a zillion times to make sure that there is no water or wort left in it and cap it until next time. Next brew I just run a gallon or so of boiling wort through it, recirculate that, and then turn on the water. I haven't had any noticeable problems with this. I still get good flow and haven't noticed any off-flavors I would attribute to poor sanitation. How do you folks clean / sanitize your CF chillers? Thanks. nathan in madison, wi Return to table of contents
Date: Fri, 08 Jan 1999 02:52:49 -0500 From: Rod Prather <rodpr at iquest.net> Subject: Scotch Ale/Scottish Ale Spencer, please note that the BJCP guidelines refers to the style as having "A faint smoky character from the use of small amounts of peat-smoked malt is sometimes present." The AHA guidelines makes no mention of smoked malt or a smokey flavor. Perhaps I am wrong but many years ago, before I even heard of the AHA, I was told that the distinction between Scottish Ale and Scotch Ale was that the later contained smoked barley. Remember that in Scotland, Scotch refers to the drink, not to the place of origin. Thus the name, Scotch Ale. Any Scots out there to qualify this. > As typically made in Scotland, neither has peat-smoked malt.

Date: Fri, 08 Jan 1999 10:06:40 -0800 From: "Michael P. Beck" <stilts at usa.net> Subject: Astringent Porter I transfered my first all-grain brew to the secondary last night and it tasted a bit astringent. Here's a rundown of what I did: Not Yet Name Porter Recipe for 2.5 gallons: 3.8# British 6-row (a "gift") .4# 60L British crystal malt .25# chocolate malt .5 oz of Norther Brewer leaf hops (9 AAUs) I mashed for 90 minutes at 152 degrees with 1.5 gallons of very soft water treated with 1/4 tsp of gypsum. Sparged with 2 gallons of 168 degree water. Brought wort to boil, added hops after break and boiled for 60 minutes. Chilled with immersion chiller (wow, was I impressed with that!). Pitched 1 qt. starter made from dry M&F ale yeast (another "gift"). I had a nice vigorous fermentation within 8 hours (I went to bed after pitching and when I woke up there was a 2 inch thick krauzen head). Fermented for 6 days at 66 degrees. Transfered it last night to my old Mr. Beer 2.5 gallon plastic wannabe barrel thing (finally found a use for it). Now, I know that too high a sparge water can add an astringent taste but that certainly was not the case...I had trouble keeping it at 168. I did notice a few (and I mean "few") husks in the cold break. That probably contributed to the astringent taste. Im just curious as to what I can do to bring the astringency down. I know age will help, but is there anything else I can do to bring the tannin level down? cheers, mikey. BSSC/121 Return to table of contents
Date: Fri, 8 Jan 1999 09:50:23 -0500 From: Dan Listermann <72723.1707 at compuserve.com> Subject: Home Malting Clifton Moore writes: <I am in possession of a large quantity (by home brew standards) of Harrington malting barley that was grown here in interior Alaska this past summer. I can not for the life of me contrive a steeping schedule that will get these devils to sync up in their germination. Some seeds wish to bolt, while others are content to sit there for days prior to first chit.> Poor boy.... I have malted off and on for a number of years. I am going through a process similar to Clifton's now with buckwheat. It won't germinate evenly either. Barley needs a peroid of dormancy after it is harvested before it will sprout. My grain comes from Briess and it has always germinated well. This may be his problem. Mary Ann Gruber of Briess suggested a germination test when I questioned the age of my grain. (I bought too much and have had it around for three years - just made a wit with it and got 28 pts / lb /gal - not bad for heimgemacht) Count out 100 corns on a sheet of paper towel, cover with another towel and wet. After a day or two, count the ones that didn't sprout. You should get at least 90%. I am told that freezing the seeds can help speed the dormancy process. As for seeping, I use an Rubbermaid cooler with a Phil's Phalse Bottom ( surprise!). I pump compressed air through the bottom for 24 hours , drain the water and repeat for another day. I pile the grain on a box screen and stick a thermometer in it. After a day or two the temperature will start to rise. I then thin the pile too keep the temperature down around 70'F. The grain must be turned at least daily or it will form a solid brick of roots and corns. After about 4 or 5 days the roots are about 1.5" long and the sprout is 2/3 to 3/4 along the length of the corn ( use a razor to split the corn). I haven't worked out a proper kiln yet. ( I did the oven thing and still hear about it to this day - I thought it smelled nice) My malt is air dried "wind malt." I am told that it is used in wit beers. I just set my box screen on two box fans and block in the sides with cardboard. It takes about two or three days for the malt to get crunchy. Then I put about 5 lbs at a time in a denim bag ( wife's pant leg ) , wait for to go to her mothers and chuck it in the family dryer for about 45 mins. Shake it out on the screen box to remove the rootlets and "viola" malt! Crystal malt can be made with the undried malt ( called greem malt) using a microwave. Just put it in a mason jar with a saucer for a lid and microwave as low as possible for about 30 minutes. It is really cool to see the crystals!

It has occurred to me that while counter-flow chilling my wort, the hop utilization may be increasing beyond the desired level. Is hop bitterness still being extracted at sub-boiling (but hot) temperatures? I assume that hop volatiles are still cooking off, reducing their flavor and aroma contribution (except when FWHing?) I typically brew in twelve gallon batches, so the time difference between carboy 1 of wort and carboy 2 could be about 1/2 hour. Has anyone found a reliable way of adjusting their recipes for this?

The darker malt flavors were very subtle, however. You really >had to look for it. One thing I didn't mention in my suggestions for cloning Prior DD and Yuengling is that many dark American beers were (are?) colored with caramel syrup such as Porterine (tm). This allows for the very dark color of DD with the mild flavor such as Thomas remembers. If we put enough dark malt in to get the color, we may end up with too much dark malt flavor. >From http://brewingtechniques.com/library/styles/sidebars.html: "What exactly is Porterine? According to Bernard Black of Mangel, Scheuermann & Oeters, Inc. (Huntingdon Valley, Pennsylvania), Porterine "is a trade name of a caramel color derived strictly from corn syrup. This product was originally formulated by The U.S. Malt Company to provide colloidal compatibility with malt beverage protein." Mangel, Scheuermann & Oeters is the current trademark holder and continues to supply Porterine to the brewing industry. Porterine's function today is still to convert regular beer into porter. Some brewpubs and microbreweries use the product to make color adjustments to their beers as well. Porterine has a dark brown color (878 L) and a specific gravity of 1.386." I have made caramel in the past from table sugar to color rye bread. It is a bit dangerous, so wear long sleeves, gloves and eye protection. Maybe a welding face guard. Put 1/4 cup of sugar in a thick pot and heat until it melts. After it melts, it will begin to boil. Stir (a wooden spoon works well) to prevent burning (carbonization). When it reaches desired darkness, quench it with water. tThis is the dangerous part - it will splatter, especially if you do it too slowly and that stuff is 450F and sticks like napalm! - don't blame me if you don't wear protection and burn yourself. It's also messy, be sure to clean up after yourself or you'll lose beer bullets. Stir to dissolve the hardening caramel. If you don't stir while it's hot, the caramel will stick to the pot, costing more beer bullets. I don't know if you could pressure cook a thick corn sugar syrup (in a separate pot in the pc) until it darkened enough. I think I'd just accept a little more flavor or a little paler color than the original. Or try to get Porterine. Do any HB suppliers carry it? Jeff The only problem with this is that it can have a bitter flavor which I suspect commercial products don't have. -=-=-=-=- Jeff Renner in Ann Arbor, Michigan c/o nerenner at umich.edu "One never knows, do one?"

Date: Fri, 08 Jan 1999 10:58 -0800 From: "George De Piro" <George_De_Piro at berlex.com> Subject: Home malting Hi all, Clifton is having some trouble malting his Harrington barley. In particular, he is getting very uneven germination and a disappointing % of germinating seeds. I have malted Harrington and found it to be a quick and relatively even germinator. Problems you may be having: 1. Dormancy: the seeds need to experience an appropriate period of dormancy before malting can be attempted. This time should be about 2 months. If you try to malt grain without giving it an appropriate dormancy period you are likely to experience highly variable germination. It should be stored cool and dry during this time. 2. Improper storage of the barley: the seeds are alive and respiring. If they have too high a moisture content (>20%) and are kept warm (>5C; 41F), the barley can only be expected to survive a couple of weeks (Kunze presents a table of barley survival rates on p.113 of _Technology Brewing and Malting_). Of course it won't all die, but you will lose a lot of viability and weaken some of the seeds so that they do not germinate quickly. If the barley is stored in a large mound the interior will get much warmer than the outside (due to heat of metabolism) and it can be expected that seeds from the interior will suffer more damage than those in the cooler part of the pile. This would lead to uneven germination and poor viability. In an extreme case (very moist barley) the heat of metabolism can keep the barley warm enough to support mold and fungal growth, even if the surrounding air is relatively cool. The seeds are then ruined. 3. Not enough removal of CO2 and/or supply of oxygen during germination. This is dependent on your steep schedule and equipment. I believe that this is possibly the most important factor in achieving good germination. The germinating seeds are undergoing frantic metabolic activity and generate a lot of CO2 and need a lot of O2. Bubbling air through the water is not adequate to meet the seedling's needs (Kunze, _Technology Brewing and Malting_ p. 118). It is best to minimize the time the barley is covered with water. I got good results (very fast, fairly even germination) by steeping the barley for 2-4 hours (completely changing the water every hour and pouring the barley between buckets to ensure good mixing and aeration) and then draining the water and performing an "air rest" for about 20 hours (rinsing and turning the seeds every couple of hours to keep them cool and well-aerated; yes, I even got up in the middle of the night to do this; yes, I take this stuff too seriously). The seeds will absorb the moisture that clings to them during this air rest. Don't allow the barley to dry out. After the first air rest the barley is again covered with water for a couple of hours and then given another air rest. According to the books, it is towards the end of this second air rest that you should see rootlets forming. My home-malting experience was different: I had rootlets growing during the first air rest! The folks at Briess that I was talking with postulated that my overly-anal attention to keeping the barley well-aerated was the reason for this rapid germination. Some people may recommend the use of gibberellic acid to stimulate germination. Gibberellic acid is found in small amounts in barley seeds, and is a metabolic product of Fusarium mold. It can be used to shorten germination time, but it will not help you achieve more even germination. Gibberellic acid promotes the formation of proteolytic enzymes faster than the diastatic enzymes, so care must be taken not to overdose the barley or it may end up producing a darker wort than desired (overly intensive protein breakdown forms excessive amino acids which are than available to form melanoidins which will deepen beer color). I don't like the idea of using additives in stuff destined for my beer, so I wouldn't use gibberellic acid. Maltsters in Germany are not allowed to use it in the production of malt for Reinheinsgebot beers, and they do just fine without it. We can, too. In my admittedly limited experience, intensive aeration will produce quick and even germination. If you do want to use it, it is best applied to the chitting malt after the last air rest at a rate of 30-80 mg per metric ton of barley. How you do that is up to you. Clifton mentions that he soaked the barley in iodophor because he was concerned that micobial activity was hindering germination. While there has been work done that links microbial activity with reduced germination, soaking the barley in halogenated santizer is likey to spoil its flavor (Siebel notes). It may also inhibit germination; I don't know for sure. As a final note I will mention that it is useful to track the moisture content of the barley throughout the malting process. This is easily done: accurately weigh a barley sample. Spread it in a thin layer and gently bake it (~100C, 212F) for a short time. Weigh it again. Bake it some more. Weigh it. Continue this process until the barley is at a constant weight (should take an hour or less). If you crank the heat too high you will start to scorch the barley and it will lose weight as it burns. Don't do that. The difference between the original weight and the dry weight is the amount of water you drove off. If you need more info about malting at home search the HBD archives for some posts of mine from early last year. I know that a few others out there (like Jeff Renner) have also malted at home, so they may be able to add more info. Have fun! George de Piro (Nyack, NY) Return to table of contents
Date: Fri, 8 Jan 1999 11:46:25 -0500 From: Brad Trowbridge <trowb at tsp.sheridan.com> Subject: yeast cake I have a question about using the yeast cake from a prior batch. I quickly browsed through the archives and read that several people do this, but couldn't find any specifics about this process. First off, I currently have an IPA in the fermenter which used wyeast 1056 american ale, and would like to use the yeast cake for my next batch. I plan on cooking up my next batch the same day I bottle, so there won't be any storage time involved with the yeast. My first question concerns procedure. Do you just dump the fresh wort into the fermenter with the yeast cake and all the gunk left over from the previous batch? I wouldn't think this would be a good idea, especially since my next beer is going to be a cranberry ale, and I don't want it to be overly hoppy tasting. Any thoughts? Can I simply scoop out the yeast cake and place it in a sanitized container while I scrub and sanitize my fermenting bucket? Should I do anything to the yeast while its waiting (add water or wort or anything)? Will the fact that I fermented a strongly hopped IPA with the yeast have any effect on the taste of my cranberry ale? Thanks in advance for your help. Brad Return to table of contents

These have a moderately peaty taste that is strong enough that I cannot believe that the peat flavor is from yeast alone. I've used the W-Yeast Scottish strain literally dozens of times, and its smoky quality is much more subtle than that found in these Scottish beers.

Date: Fri, 8 Jan 1999 12:42:02 EST From: NEWTRADBC at aol.com Subject: A different view of St. Pat's "Lynne, I guess maybe we all could do business elsewhere if you want to treat your customers this way. Marshall George Glen Carbon, IL" Exactly how did Lynne treat the customer poorly? She apologized for the shipping delay, which was only partly her responsibility. And she truthfully told the customer that if they found better business elsewhere they should take it there, and that would be best for both parties (the customer and St. Pat's). Hell, I think it's pretty good that a store is WILLING to apologize, yet not willing to kiss the ass of a customer that has already pretty clearly i ndicated they're taking their business elsewhere. If a business believes has done everything properly then there is nothing more to do, you can't satisfy anyone. I have ordered from St. Pat's on occasion, especially since they picked up the moravian and Weyerman products I have ALWAYS received the orders promptly. ONCE, they sent the wrong wyeast. They also promptly sent the right yeast to me when I called (and didn't ask for the other back). Since support of locals has been a recent thread, let me note that now that my local supplier [Flying Barrell, Frederick, Md] can get the Weyerman, I haven't ordered from Pat's in a little while. Sorry, I don't buy that this customer has been treated poorly at all, and I think you're slamming a business unfairly. T. Bergman, Frederick MD. Return to table of contents
Date: Fri, 8 Jan 1999 12:15:39 -0600 From: "Membership" <mship at mhtc.net> Subject: Decoction mashing I ventured into decoction land for the first time, wishing to compare the method to infusion for maltiness, etc. As I have already done this, the following query will be for future use...We'll see how this Dunkel turns out. I am using very well modified malts - S/T for DWC Munich is currently 45. I will thus forego a protein rest, doing only a beta-glucanase/enzyme rest (1.18 qt/lbs) and infusing for a beta rest at 140 (per George Fix) at 2.01 qts/pound, then decocting to 158 and mashout, respectively. Two questions: 1. Too thin on the beta rest? 2. I wish to have a fairly dextrinous wort, so I want 20 minutes at 140 and 40 minutes at 158. Easy enough with infusion, but when decocting, even if I pull the decoct portion as soon as I infuse to 140 (which I won't - I would assume it would be better to rest the rest you want, then pull), by the time I raise the decoction to 158, rest, boil for 30 minutes, the main mash will have rested considerably longer than 20 minutes at 140. How does this not result in a very thin, extremely high maltose/maltotriose ratio? Looking at Richman, Noonan, and others, and at the Weihenstephan "classic" triple decoction, their rests seem wildly long to me, the naif... (2 hours at 122, 140, etc...). Is it because pulling the decoction, by removing the thick mash, effectively slows the main mash reaction to nil, until the decoction is put back? Thanks for any and all help - Enjoy the news!

Date: Fri, 8 Jan 1999 16:38:47 -0600 From: John.Wilkinson at aud.alcatel.com (John Wilkinson) Subject: Sports drinks I found Victor Farren's post concerning drinking beer after exercise very interesting. As it happens, I stumbled on this myself recently. Thanksgiving morning in Dallas there is an eight mile race downtown called the Turkey Trot. I have been running it every year since 1975 and usually by the time I get home I have stiffened up so I can hardly hobble out of the car to the hot tub. I usually sit in the hot tub and have my first beer of the day. This past Thanksgiving I ran the Trot as usual along with my son and daughter-in-law. Actually, "along with" is only in the sense of being in the same run. Their 24-28 year advantage age wise seems to help them get to the finish line considerably ahead of me. Anyway, this year we were going straight from the run to my daughter's house for Thanksgiving dinner. Since I don't expect others to know what my latest beer whim is, I had a cooler of Guinness and Fuller's ESB in the truck. When we got in the truck after cooling off my son said something about a beer being nice at that point. I had him fish out a couple of Guiness which we sipped on the way to my daughter's. Lo and behold, when we arrived and I got out of the truck, no stiffness or soreness! I thought I had discovered a new alternative to the hot tub. As with so many things, though, I had finally stumbled on something that a lot of others already knew. I had meant to post my discovery to HBD but, as with so many other things in my life, I never got around to it. Scooped again!

Date: Fri, 8 Jan 1999 20:26:02 -0500 From: pgarofalo at juno.com Subject: Prior Double Dark I responded privately to Kevin regarding my knowledge of Prior Double Dark, but seeing the level of interest, I thought I'd share some information with the forum: First off, Prior Double Dark was made by F. X. Matt (now Saranac) in the 70s and 80s, and maybe even further back. I have no knowledge of its having been made in the Philly area, but of course I could be wrong. It was, until very recently, a draft-only product, and one with a cult following (as Thomas points out). It was probably voted the best dark beer in the late 70s because it was the *only* dark beer around (not that it wasn't a good one...)! It may please you to know that it not only is still made (under the name Saranac Black Forest), it is also available in bottles. Check out www.saranac.com for more information. The beer is labeled as a "Bavarian black beer" (can you say "Schwarzbier?"). The brewery's web page gives precious little detail except the gravity and what food to pair it with. The label is a little better, proclaiming that "it is brewed with a delicate balance of slow kilned caramel and two-row malt, as well as five varieties of imported and domestic hops." The one I had last night had a definite hop bitterness, with a lightly hoppy aroma and a hint of caramel. The flavor is very clean, with a hint of caramel, but not too much. By the way--it has been written that the Saranac/Matt lager yeast is a descendant of the Christian Schmidt strain, so that seems on the mark. As for corn, I'd say no from the taste, though they do have a cereal cooker at the Saranac brewery... Cheers, Peter Garofalo Syracuse, NY--an hour from the Saranac Brewery, and a good 6-8 hours from Jeff Renner. ___________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

This started my mind ticking... I have been thinking about enzymes a bit and realizing how little I really understand. How big are these critters anyway? Can anyone give some physical measurements or some indication of typical size of the enzymes of interest for brewing beer? I am trying to get an intuitive feeling for the size of the knife needed to cut an enzyme in pieces. And we know enzymes are denatured at various temperatures. What is the actual mechanism? Do they dissolve? I mean, get mushy and just fade away? What actually happens to them as the temperature goes above the threshold they are able to survive at? I assume we carry the enzyme carcasses to the boil kettle during the sparge. What effect do they have on the finished beer? I stand up to be chastised with the "Oh yee of little faith" chant... ...but why have I failed to pick up the answers to these simple questions in my reading of the HBD, some of the archives, and the books on brewing I have accumulated? How fragile are these buggers anyway. Temperature can kill them...shear forces may cut them to pieces...can I devise a way to smash them into oblivion? At this point, I just can not even think of the right way to search the archives to find some potential answers! All comments highly welcomed. I really would like to learn more about this subject! Gee...I hope I am not the last one to know :-) Bill Bill Macher macher at telerama.lm.com Pittsburgh, PA USA Return to table of contents

I sincerely doubt that the open fermentation method that Dave Burley uses in any way increases the risks of wild yeast contamination.

Can anyone give any hints on what to do, if I wanted to take advantage of the local wild yeasts ? I tried this once where I juyst took the wort and left it out uncovered in the back yard for 24 hrs.
