---------------------------------------------------------------------- Date: Tue, 18 Jan 2000 12:41:41 -0900 From: Clifton Moore <cmoore at gi.alaska.edu> Subject: converted keg fittings I have two kegs that I use for brewing. The first is set up with a 1/2" union welded through the lower rim with a dip tube through a false bottom. The second has a brass bulkhead fitting in the base of my boiling keg. I have never in the years of use had any trouble with any of the fittings. If I were to do anything different I would make the boiling kettle fitting size 1/2" inside diameter so that it might more easily pass whole hops. As it is I tend to strain most of the hops out of the kettle near the end of boil. Clifton Moore Return to table of contents

Date: Tue, 18 Jan 2000 17:14:55 EST From: MaltHound at aol.com Subject: Zapap Bum Rap? In HBD 3223 Brian Dixon spoke thusly: <> Brian, Actually, yes, I do remember that Zymurgy test article. However, my recollection of that experiment was that all of the devices tested were very serviceable and that the differences in extraction were essentially insignificant. The amount of variation in extraction yield is likely to vary more batch to batch than the difference between these mashing systems. Quoting from the article: "This is not real science. The measurement errors in the distribution of the grain and the measurement of the volume of runnings are enough to account for the 3.32 points between the highest and lowest extractions..." I also don't think that one should make broad conclusions based on a sample of one test. One particular flaw that comes to mind about this test is that, unlike Listermann Phalse Bottoms, not all Zapaps (or copper manifolds for that matter) are created equal. I would hypothesize that if you drilled out a Zapap with exactly the same hole size / pattern as a Phalse Bottom it would/should lauter essentially the same. Also, as noted in the quote above, the way the mash was split between lautering systems tested is suspect. I would be interested in any theories of reasons why a Zapap is inferior. Not so much because of the inherent utility of a Zapap (I don't even use one anymore) but because it would be useful in determining what the important parameters are that need to be considered in lauter tun design. In any case, I think we would both agree that the easiest thing for a homebrewer is to just throw in another 1/2 Lb of grain when presented with a potential extraction difference as small as this.

Date: Tue, 18 Jan 2000 16:28:31 -0600 From: Susan/Bill Freeman <potsus at bellsouth.net> Subject: Re: converted keg fittings I think all I said was that IMHO fittings on stainless kegs and stock pots are better welded than threaded through the side. Brass works, but must be treated to recuce the lead leaching into the brew. BTW 1/2 ball valves have only a 3/8 interior hole. 3/4 ball valves have a 1/2 hole through the ball. "the perfesser" uses a long version of the EasyMasher to strain hops out of the outflow of the boiler. The whole hop bed also filters a lot of the hot break out at the same time. The science of brewing is not finite. Nor is the way each of us chooses to deal with ourt equipment.

Date: Tue, 18 Jan 2000 20:37:38 -0500 From: "Steve Postek" <spostek at voicenet.com> Subject: Oxygenating wort and high final gravity I have several related questions: First can anyone tell me how long an APA should ferment at about 68 degrees? I am new to brewing and it seems it is finished after about 10 days (six in the primary and four in the secondary with the finishing hops). The SG is steady but higher than expected. Started about 1.050. Now about 1.022. The recipe calls for 1.015. I am guessing if I bottle now I am going to get a very malty flavor in there which is quite uncharacteristic of an APA. I know that there has been a long discussion on early racking but aside from that is six days too long in the primary? Is there any standard? I have seen people say anywhere from a day to a week. When the final gravity reading is high but steady and I know it should be lower, is there anything I can do after the yeast runs out of gas? Can I pitch more yeast? That doesn't sound like it will work if I can't oxygenate after pitching. My last question is what is the best way (cheap) to actually oxygenate? I tried two consecutive times to use a slotted spoon and a whisk (egg beater). I guess maybe I did not do it long enough. I see the more expensive fish tank aerators with the diffuser ends for sale. Is that worth it and if so how long do you aerate with that? Has anyone out there tried using an electric mixer? If so please share your method. I see in books that one selected method is capping a glass carboy and shaking. I am by no means a physics or chemistry expert but I don't see how oxygen will get into the vessel and mix with the wort if the end of the carboy is capped. Thanks for any help in advance.............. Steve Postek Limerick, PA spostek at voicenet.com Return to table of contents
Date: Tue, 18 Jan 2000 21:17:16 -0600 From: "Paul Smith" <pksmith_morin at msn.com> Subject: Dextrins and mouthfeel My experience differs from Daves Burley's regarding dextrins and mouthfeel. I simply cannot agree with Dave that dextrins do not contribute to mouthfeel. Dextrins may not be as effective a source of mouthfeel as (especially, medium-molecular weight) proteins, and may in fact contribute other, off effects, i.e., a "worty" taste, but all one has to do is mash two worts: one at 145 to conversion and one at 158 to conversion, and compare the mouthfeel to notice a difference. 158 is well outside the optimal range for proteolysis, so the comparably greater mouthfeel would be due to the longer chain effects of a-alpha amylosis. However, I do not have any data points to support this; I'd be interested to see the "many scientific investigations" Dave refers to show that "dextrins do not contribute to mouthfeel." Dave? I know in practice, both in my own endeavours and at breweries where I've worked, a mash at 158 is used specifically to lend body to, e.g., pale ales. Paul Return to table of contents

Yes, I remember this quote, and I know from personal frustrating experience that these same measurement errors can make a huge difference in perceived extraction points (my 'yield' dropped from 85%-90% down to 70% after I calibrated my electronic scales, water measuring containers, and dipsticks for my pots ... this was due to measurement error!) I concur on this point. > I also don't think that one should make broad conclusions based on a sample > of one test.

Also, as noted in the quote above, > the way the mash was split between lautering systems tested is suspect. Very true also. Variance among copper manifolds and Zapap's are probably great (number of holes, size of holes, pattern of holes, size of buckets, manifold shapes/diameters/lengths/etc). > I would be interested in any theories of reasons why a Zapap is inferior. No good theories here. Your explanations seem to make sense to me. > In any case, I think we would both agree that the easiest thing for a > homebrewer is to just throw in another 1/2 Lb of grain when presented with a > potential extraction difference as small as this. Yes! Of course! [grinz] The only statement I was making was that I based my past opinion on that article. I've read other literature on lautering and am convinced that different systems do affect the efficiency of the extraction. I believe that the primary factors are temperature and rate. Keep the temperature hot enough and the rate slow enough, and you can get good extractions from a variety of systems. So why do I still bet on the Phil's Phalse Bottom (now Listermann's ... but I'm an old fan of the original name ... and owner)? Because a) it has an extremely good reputation, b) at least one article found it to be the best (even though repetition of the experiment may yield different results ... at least the Phalse Bottom didn't place last near the last), and c) more than one source (forgive my bad memory on which ones) claimed that lautering systems do vary. Call it a safe bet on my part. Like I said in the beginning, "go with a Phil's Phalse Bottom for $13 or so" and you won't go wrong. Yes, other systems may perform as well or even better. But the Phalse Bottom will get the original poster a known good performer, will remove doubts about his Zapap, and will also speed up the initial phase of his sparging ... the re-running of his wort to clarify it and to 'set' the grain bed. Or, for a lot more work, money, or time spent in the brewing process, he can match the performance of the Phalse Bottom. I weighed these pros and cons when I bought mine, and went with the Phalse Bottom and have had nothing but pleasure and good brewing since. Just my 2-bits worth I guess! YMMV. Happy brewin'!

Date: Tue, 18 Jan 2000 22:04:38 -0700 From: Paul Dey <alldey at uswest.net> Subject: New brewery plans Brewers, Forgive me father for it has been many days since I've last brewed (and many more since last I posted). I've contracted a deadly disease that distorts priorities, alters time and limits fermented output. >From recent posts, it seems others may also have this plague. My version became evident following spawning for the second time, then a new house, then....ahhh. Get to the post. I intend to set up my milling operation in the garage where my none-exploding very nice MM (thanks Mr. S) will be set atop a bin of sorts to gather the grist and powered with the same electric motor I've used in my past home. I'd like to route the grist to the basement "brewery" which is right below and inside from the mill. I'll need some sort of smooth tube to conduct the grist. I'm thinking 4" round vent pipe or perhaps rain gutter. Comments and suggestions? I'd like to be able to grind all the grist and then go to the brewery and release a gate or something to drop the grist into the tun. I'm concerned that the grist will get hung up, especially in whatever vessel I use to collect to grist in the garage. I guess I need the grist to emerge from the bottom of a conical vessel to ensure all the grist goes to the basement? I have the water lines plumbed and will be running electric soon to power the RIMS (yep, GFCI all) and shed more light. Any suggestions on vent fans? I saw a 70 cfm? (forgot the unit, amount of air it moves per unit time) fan with a light the other day for $50 that seemed like it'd work o.k. hung over the kettle. And I need to run the propane lines. My Gawd, he's got propane in his basement! Nope, 500 gallons outside, furnace and water heater in the basement, gas snifter mounted next to furnace close to the floor which shuts the gas supply line off at the first hint of combustibles. I'm a bit concerned, however, that it may be so sensitive that everytime I go to light a burner the gas will shut off. That would make me thirsty.

Date: Wed, 19 Jan 2000 00:27:05 -0500 From: "George de Piro" <gdepiro at mindspring.com> Subject: yeast propagation / All grain advice / malta starters / Siebel Howdy all, Mike asks me for more details about why the volume of a yeast starter should never be increased by more than a factor of 10. The reasons are: 1. You want the yeast to be able to quickly ferment the wort so that invading organisms will not have any nutrients to consume. By pitching an adequate number of yeast cells you ensure a quick and complete fermentation. 2. Yeast are limited in the amount they can divide by sterol. Sterol is an important part of the yeast cell membrane. It is so important that yeast cannot live and divide with less than 0.1% of their weight as sterol. They can have a maximum of 1% sterol by weight. Sterol is made using oxygen (this is why yeast need oxygen; they do not use it for respiration in a brewery environment). Because of the above limitations on yeast sterol content, they can only divide three times before they fall to a level of sterol that prohibits further budding (when yeast divide each cell gets about half the cell's sterol). Unless more oxygen is added, the yeast will not be able to divide further. If you have pitched to few yeast cells, three divisions will not yield enough yeast to quickly ferment the wort. This is the cause of many stuck fermentations. If you underpitch the starter (or your batch) the result is a slower start of fermentation (which can lead to microbiological trouble) or a stuck ferment. Underpitching also does stuff like increase the amount of higher alcohols (the so-called "fusel oils;" alcohols with more carbon atoms than ethanol, which has two). This is a common homebrew flaw (and a flaw in some commercial beers, as well). - ------------------------------------ Bruce Carpenter asks for some first-batch all-grain advice: He asks if he can mash and lauter in the same vessel. The answer is a resounding "Yes!" In fact, most small breweries are set up this way. The combination mash-lauter tun is called, accurately enough, a "Combi-tun." It does limit some of your mashing options, but not terribly so. It is a great way to keep your first few batches simple. He also asks if foundation water (the water under the false bottom) should count toward the volume of mash water when figuring the amount of hot water to mix with the grain to hit a specified temperature. In my experience, no, it should not be counted. - ----------------------------------- Alan Tallman describes using Malta as a starter: "After one week the Malta beer tasted very sour and checked in at 1022. After one more week, (down to 1020) the sourness was gone." Some questions and comments: What was the OG of the malta? 1020 is kind of a high FG, too. I believe that this could be caused by a lack of amino nitrogen in the malta; it is made using a large amount of corn sugar and other low-protein adjuncts. Perhaps adding yeast nutrient to it would remedy the situation and make it more useful as a starter media? - ---------------------------------------- Rob Moline posts the closing of the Siebel Institute, where he and I were classmates two years ago. This is indeed a very sad day in the brewing industry. It may be arrogant of me to say this, but there are far too few craft brewers in the USA who actually know even the basics of brewing science and quality control. I have met countless brewers who cannot even culture their own yeast or figure out why their beer develops diacetyl on the shelf. To me this is inexcusable; when you choose a profession you should do your best to educate yourself about it. Ask your local brewer if they have read Malting and Brewing Science or Technology Brewing and Malting (or even the HBD for that matter!). More often than not, the answer is, "No." There are plenty of brewers out there in need of education. It is truly sad that Siebel will not be an option for them any longer. I do have one criticism about Siebel, though: their courses were very expensive considering that they were not offering accredited degrees. I would gladly pay Siebel's tuition (or even more) to earn an MS in brewing science. The certificates that Siebel offered are essentially useless outside of the brewing industry. Perhaps that can be something they consider in their attempt to restructure? Have fun! George de Piro C.H.

Although I used a similar method on a pLambic last year, I would hesitate to try souring a whole batch of stout. I've heard it can turn quite quickly (QDA), and before you know it, it could become undrinkable. I recently attempted a Guinness draft clone (10 gallon, all grain, 1.041 OG) and when I racked to the fermenters, I held back about 3% of the wort. Actually, I saved back 48 oz, with the idea of adding back about 38 oz. The rest was for absorption by the malt, boiling loss, etc. I racked this to a sanitized gallon jug and added 1/2 lb crushed pale malt, which supposedly harbors lactobacillus bacteria. No yeast was added. I kept this on my mantle above the wood stove (probably around 80-90F) for around 5 days, and it had really become malodorous (it stank!) by that time. I strained, boiled, chilled, and added it back to the main batch when I racked to secondary, which went for about 3 weeks before carbonating. It finished around 1.015. The result was a slight "twang" which does make it more like a Guinness than any of my previous attempts. I wouldn't hesitate to do it again, though I may slightly modify the amount I soured, or my souring process. Good luck.

However, new plugs are often more expensive than a used keg If this doesn't work, IMO the easiest and cheapest solution is to use hose barb to 3/8" female flare fittings at the end of your lines and use connectors with 3/8" male flares rather than hose barbs.

From that page, scroll to the bottom of the page and click "Technical Quarterly;" scroll down about midpage to the Practical Brewer area, and go to the "PDF DOWNLOADS" link there. The files are chapter by chapter, not the book as a whole. (Thank you to the MBAA for providing this gratis). _________ Regarding the use of "burst sparging" as a technique (and the "coining of a phrase"): This is the term we used at Goose Island microbrewery, where I worked as a quality control technician. I have heard it used elsewhere. Kunze refers to it as "periodic sparging" (pp. 235-236). It is not the same as continuous sparging, and, yes, it did kick my extraction up from 85-95%. Since you are not maintaining a constant volume of water on top of the grain bed, but rather you are allowing runoff to proceed to the grain bed depth and then sparging until 3" or so is on top, you are setting up a sparge "pump" of sorts, since the density differential between the sparge water and the mash-entrapped wort is maximized. My apologies to whomever has a problem with my use of the term "burst sparging." As graduate students at Berkeley, we were accustomed to defining, then naming a phenomenon when we observed it in nature, providing we knew of no other name. When we did use the name, we promulgated it along with our methodology and findings. That way we could demand royalties when the term gained currency in the popular imagination. So everyone who wants to use this technique, please call it "burst sparging" and send your money my way... There is no doubt this method has increased my efficiency, as corroborated by several batches with the method as a control: New: Old: 1.5# munich 1.5# Munich 17.75# 2-row 20.5# Munich 1# crystal .75# Crystal 20.25# total 22.25# total OG: 14.1 14.1 12 Gallons 12 Gallons ________________ I would agree with Steve Alexander that Kunze's book has errors in it (due to obvious translation problems, as in "...it is therefore better to do without carbonation as much as possible...," when he probably meant to say that "...sterile forced-carbonation is difficult, as sinter candles are notoriously difficult to maintain clean..." (see pg. 432) >From everything I've read by Steve, he knows a universe more about chemistry than I do, and as I stated in my post there are other, more germane texts if you want brewing and cellar chemistry, especially in the areas of research. If you want this, as Steve suggests, look into magazines and other sources. I enjoy what issues of Technical Quarterly I have read. However, I still think Kunze's is a great text. By "thoroughly discussed" I mean enough chemistry is in there to provide the basis for practical brewing at a commercial level (my interest), and the discussions of malting, brewing, cellar and packaging technologies fill a gap left by other books.

Use a clutch or shear pin arrangement or if you attach the drill directly to the mill via that tempting 3/8' in. rod, be sure that you have some way to shut the motor off automatically. Eventually, you will find detritus in your malt, like rocks, chunks of rubber or bits of metal. I have found all three and didn't see them as I was loading the mill. Luckily, I had the foresight to loose mount my drill and have it so the power cord was shortened to the point that a stuck mill would rotate the drill handle and pull the plug. Simple and it's worked so far. Here's a needed gadget - a clutch or shear pin arrangement for the drill chuck. It may be as simple as a Teflon(R) sleeve with a metal tube around it that fits the chuck or vice versa. Anyone looked at how a drag on a fishing reel works? - --------------------------------------- David Houseman asks for a non-momily reference about Guinness' sour tang. If you have access to it, check out Malting and Brewing Science. If you can't find it let me know which edition you have and I'll try to locate it, as it is in an obscure place. I read it in the original edition and may have it marked. I believe I saw the 3% reference there. It was a two line comment sort of " Oh by the way.." Don't recall if Guinness was specifically mentioned, but the reference left little doubt, if I recall correctly. Adding sour beer would be consistent with the "stale" beer origins of Guinness and porters and "three threads" and "entire" and all that. It is also rumored that this sour beer was the secret additive that Guinness Dublin shipped to its breweries around the world to maintain quality. Just a rumor, AFAIK. Is that where Kentucky Fried Chicken got the idea? And I have had the sour beer taste in Guinness in the UK many years ago, but not recently. It did taste a little spoiled by modern standards, but was consistent from pub to pub, so I assume it wasn't handling and sanitation at the pub that was the problem. Things do change, whether we like it or not. Much as we would like to believe it, I sincerely doubt it if there are any commercial beers which represent how beer used to taste and why it became famous. For starters, we all know that the OGs today are a far cry from historical levels. Hopping levels are less, although some really early beers had low or no hops. I even doubt the Real Ale efforts have been successful as the commercial OG's are so low. Makes me doubt ( but still appreciate) the efforts of the BJCP to standardize tastes based on today's beers. Maybe they also need a "real beer" branch of categories utilizing historical OGs and hop levels dating to the 1800s, when I believe beer reached its peak.. Chances are good that Guinness would not be around if they made beers of the original strength and quality Too highly taxed, auto insurance companies and legislators ( the horse could find its way home by itself - cars can't) and two world wars with limited grain supply and, perhaps, a sour taste (Coke trained drinkers like it sweet and not bitter or sour) mitigate against that. Look for a blond Guinness at your supermarket in the future! Or have I seen one already? It may be the sour taste was needed to make the MUCH bigger beers of yesteryear less cloying. With the present shamefully low OG. perhaps Guinness doesn't need or can't withstand the addition of stale or sour beer, at least in this market. If you do use the sour beer, try an OG of 1.070 - 1.080 or thereabouts. I don't want insurance companies and laws and history dictating what I can taste. I'd like to try the original Guinness! Which is why I homebrew. - ------------------------------------- Keep on Brewin' Dave Burley Return to table of contents

The list is a great source for all things pepper (chile) related (especially growing peppers and making hot foods). There is also a couple of subscribers to the Chile Head list that annually conduct a habanero mash, where large amounts of habaneros and other ingredients are fermented. The resulting substance is strained, canned or bottled, and aged. Reportedly, it is very good. I was going to post the procedure, but I couldn't find it. If anyone is interested, I am requesting it from the makers and will post it here (or send it privately) when I get it.

This was not a problem until I started using the >floating mash approach in a combined mash/lauter tun. Doughing in is tricky >when the bottom floats, and I struggle to get a clear run off. Jay Spies gave me this tip which has turned out to work very well. Get a length of tubing (about 1/2 inch diameter or so) long enough to make it around the circumference of the false bottom. Cut a slit in the tubin lengthwise along the entire length of the tubing and thread it over the false bottom. When you put this cushioned false bottom down into the lauter it fits nice and snug - keeps the false bottom from floating up as well as the added benefit of keeping any of the grain bed particles from sneaking around the edges of the false bottom during sparging. Has worked for me. -Alan Meeker Baltimore, MD Return to table of contents

I am looking for a beer that I can't find anymore, haven't seen in four years, and can't remember the name of the brew. Now that you have all the clues, "The game is afoot!" Ha Ha!! Seriously, it was in a clear bottle, had a Jalepeneo pepper in each one, tasted strongly of chile pepper (as opposed to Jalapeneo), and if memory serves the label was yellow in color. based on my recently aquired brewing knowledge (and awarness of lack of same), I surmise it was a lager of some type as it was largely flavorless but fo the pepper, but it might have been a blonde ale of some kind.

Date: Wed, 19 Jan 2000 09:38:30 -0500 From: Marc Sedam <marc_sedam at unc.edu> Subject: sparging I, too, am a big fan of the Listermann sparge arm (no affiliation, yadda, yadda...). I use a Gott cooler to hold sparge water, mash in a keg with a SS screen on the bottom, and collect the runoff in my bottling bucket (attach the runoff hose to the spigot reduces splashing almost completely). The last time I brewed I realized that I didn't have enough propane to finish the boil. I put 5 gal of 175F water in the Gott, guesstimated the flow rate of the sparge water and tried to match the runoff from the lauter, and took off to get propane. When I came back 45 minutes later the sparge arm was just stopping (i.e. sparge water just finished flowing) and there was 6 gallons of runoff collected. 10 minutes later I had the last gallon of wort and was in business. See? Hands-off brewing for $1500 less than a 3-tier, SS, RIMS system. ;-) Cheerios, Marc Return to table of contents
Date: 19 Jan 2000 09:01:18 -0500 From: RCAYOT at solutia.com Subject: Burst sparging I have been reading a couple of threads here lately about "burst sparging" and the other one about using a collander when sparging. Most of the advice has been good, but I think that we are overblowing the need to "distribute" the sparge water. I personally use a technique known as "semi-continuous batch burst sparging" sometimes "with grain-cutting and recircualtion" ;) When sparging, I can't think of any possible difference it can/would make for the sparge water to be over the grain bed by 2" at one time and 1/4" at another and then go back to 2" etc. Especially when pouring in the sparge water usually disturbes the top of the grain bed by a few inches at least. Personally I don't worry too much, I use a pitcher and dump in about 2qts at a time, sometimes 2 or three pitchers full! GASP! Look, this is not rocket science, if you are lautering in a vessel where the grain bed is over 6" then I think it would be difficult to really screw it up by distiurbing the grain bed. When runn-off slows down on me sometimes I stir up the whole mash in the middle of a sparge, then allow to settle for 5-10 min, then recirculate until clear, and usually make uyp some time with smoother run-off for the remainder, I also often take my spoon and "redistribute" the top layer of grain to keep channeling to a minimum. I tried to use a sparge arm for years, what a pain in the ass, to try to keep the flow rates even between runoff and sparging, especially when the runoff rate varies over the entire sparge, I never got a "continuous" sparge with a constant level of sparge water over the grain, never ever, so I guess I just said to myself, why bother? Also, I found it easier to control the temeprature of the sparge water when I dipped it out of a pot on my burner, I could start out very hot to raise the temperature of my mash to mashout and mix in some cooleer water (or just let it cool off) to keep the grain bed temp below 75C. I guess I just want to explain to the newbies out there that they don't have to worry about the minor details so much, they don't make THAT much difference. when you have mor experience under your belt, then start to play around with your technique, this is what I would call "refining" your technique. Also, when the different mash tuns are compared, I was very impressed with the extract achieved with the ZapPap or double bucket system, I never got that high an extraction, but then again I was using it when I had little experience. Although the difference in efficiency was "significant" it was not so much, just add a little more grain. Roger Return to table of contents
