---------------------------------------------------------------------- Date: 31 Jan 97 12:14:15 EST From: "David R. Burley" <103164.3202 at CompuServe.COM> Subject: Esters, RyePA, Flaming Necks Brewsters: John Goldthwaite asks: > Lately I have found myself in need of some info pertaining to > esters. Esters are the reaction products of alcohols and carboxylic acids. They are apparently not formed this way primarily in a fermentation, but are the result of a metabolic pathway in yeast. They are the primary odorants in many fruits and in low concentrations in beer may make you think "fruity" without being able to identify the fruit. At higher concentrations you may smell ethyl acetate ( reaction product of ethanol and acetic acid) and think "nail polish remover" or "solvent". You may smell amyl acetate (amyl alcohol and acetic acid) and think "bananas". If you smell "cloves" or "spices" it is not an ester, but rather eugenol which is phenol substituted with an ether and an unsaturated side chain. Fusel ( higher molecular weight) alcohols are reputed to provide an oily, solventy smell sometimes. - ---------------------------------------------- > Alan Folsom sez: > > "I am interested in brewing a batch of IPA this weekend, but > experimenting with Rye Malt in the batch. Rye malt is gummy and will give you a slow lauter, as you know. Do a beta glucanase rest at around 122F as 95 -131 F is the active region for glucanase at mash pH, assuming the enzymes in rye are the same as barley . Although I didn't, you may want to do this rest at this temperature with just the rye malt ( a split mash) to prevent depleting your beer of head forming properties which come from the barley proteins. I recommend a thick mash to maximize these gum destroting enzymes' activity Even with this low temperaure rest for the entire grain bill, my rye beer had a big thick head, but I used a German Pils malt to simulate a Roggen. A split mash at the start of the mash is a good idea with fully converted malts like you would use in an IPA. My observation is that the wort viscosity in this mash is very noticeably temperature dependent, so run the lauter at a higher temperature than you normally do to reduce the viscosity. I have even drained the grain bed (gasp!) at maximum speed to prevent cooling, rinsed the bed with hot water and heated the wort up and then recirculated it to clarity, followed by a final hot water sparge. It worked great. This was more than 30% rye malt as I recall and was marginally slower than my normal sparge which I control to 45 minutes to an hour with largely barley malts. .--------------------------------------------- Tom Williams asked is it necessary (or advised) to flame the mouth of > the secondary prior to transferring yeast to storage? Personally, I think flaming of the surface has little to offer in way of sterilizing or even sanitizing the neck the of the carboy unless you get the surface temperature up there. It is possibly dangerous depending on how you do it. Above all don't put alcohol into the carboy or on the surface and light it. It will not heat the glass and you may get an explosion. I do it this way: Dampen a cloth or paper towel with *acidic* metabisulfite solution. The metabisulfite should be about 500 ppm. pH should be below 3.5, 3.0 is better, but it is not critical how far below. Use a food acid, say, citric or tartaric acid. Wipe the neck of the carboy with this cloth, removing any crud that may have somehow gotten there, but don't let the solution drip into the yeast. Since yeast can stand 100 ppm of metabisulfite, pouring the yeast out over this neck now will not affect them as the amount of metabisulfite is small and bacteria are killed above about 30 ppm with acidic metabisulfite. I cap it in a 12 oz beer bottle and put it in the refrigerator If this worries you, stop worrying. I occasionally wash my yeast in 50 ppm metabisulfite which is acidic, followed by cool boiled water twice and pitch into a starter. I've never done it, but I suppose the yeast will be stable in the water if placed in a refrigerator without pitching. Others have written here about using distilled water to store their yeast, minimizing the potential for bacterial contamination. Although some commercial brewers pitch washed yeast directly, apparently there is evidence that acid-washed yeast can sometimes not behave "normally" for the first fermentation (maybe because its uncontaminated??). Since I pitch the yeast into a starter before it goes into a batch, I have never seen this problem. - ----------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3202 at compuserve.com Voice e-mail OK Return to table of contents
Date: Fri, 31 Jan 1997 12:36:20 -0500 (EST) From: JohnT6020 at aol.com Subject: How does beer affect you? What is the feeling you get from drinking beer or any other alcoholic beverage. I'm serious. I would like to read some different people's description of the "feel-good" feeling they get from alcohol; not the drop-down-drunk feeling but the level at which the effect is pleasant. Can you describe this feeling? What kind of thoughts occur to you that would not happen without the drink. Does the drink make any unpleasant thoughts or feelings go away, become less important or become solved? Does the drink have any effect on physical pain. If you can put together a description of a beer drinkers "feel-good" I would appreciate an e-mail copy. 73, JET Return to table of contents
Date: Fri, 31 Jan 1997 11:38:46 -0600 From: milder at rs6k1.hep.utexas.edu (Andy Milder) Subject: Malting amaranth Hi, I had a dream of making a high-percentage amaranth beer which would require home-malting 5 pounds or so. I've just tried test malting a pound and all I succeeded in creating was an incredibly foul stench. I failed miserably and I think I know why: amaranth is small. After soaking, the grains are 1 mm of so in diameter. Unless laid out rather thinly, there will be no air flow between grains and they will rot/mold. And if they are spread thinly, they will dry out quickly (because they're small), necessitating frequent soaking or spraying to keep them wet. Needless to say, I used a tall container- soaked them for about 24 hours, changing the water every 8. Then I drained the water, and let it sit for a few days, soaking and draining every 8 hours or so to keep the grain wet. The smell just got worse and worse until I gave up and tossed the mess. Has anyone tried this? If someone has used it as an adjunct, how did you use it? Milled or flour? boiled for how long before adding to the mash? Does anyone know the gelatinization temp? I tried using 10 oz of flour, but I got no noticable flavor contribution and I'm afraid I didn't gelatinize it first. Amaranth has a unique kinda nutty flavor that I think would be a great addition to some types of beer. Thanks in advance for any help, Andy Milder Return to table of contents

I might >be inclined to do some "yeast washing" but that sure sounds like a lot of >work for little gain. There was obviously a little residual activity continuing and the yeast flocs with their attached CO2 bubbles were not bouyant at pressure. When you opened the bottle and released the pressure the CO2 bubbles expand and the yeast flocs rise. You may not need to acid wash your yeast for reuse, but washing the 'sludge' with sanity water to remove the wort/beer will prevent this problem and then storing the yeast under pure water should improve the survival of the yeast (see HBD article last 1996). See 'the brewery' website for washing details. Steve Alexander Return to table of contents
Date: Fri, 31 Jan 1997 10:06:50 -0800 From: Mark Riley <mriley at netcom.com> Subject: Aeration (are we still having fun? ;-) Hello HBD, While I personally haven't adopted an aggressive aerating regime (yet), I thought the following might be pertinent to the current thread: I know from my aquarium days that aeration is best accomplished with the largest air to water surface area and a mechanical means of moving water in the tank so that it flows past this surface. The air stones you see in an aquarium contribute relatively little to directly aerating the water since the bubbles have a small surface area compared to the top of the tank. It is the motion of water created by these air stones that keeps the water moving past the air/water interface (basicly the top of the tank) where the water can pick up oxygen. With that in mind, perhaps it isn't necessary to have the air stone going full blast, but instead, set at just the right speed to get the wort in motion. There would be the benefit of less foam (who needs it ;-) and for those using oxygen, less oxygen bottles to buy. So... with that all said, a crazy thought pops into my head. Picture this: A small impellor on a long shaft is driven at moderate speed by a small DC motor (kinda like those things they make milk shakes with but not spinning so fast). This gets the wort in motion but doesn't generate (much) foam. After an initial blast of oxygen to purge the head space with the pure gas, set the oxygen on trickle. Less foam, less oxygen to buy (and hopefully happy yeasties). This really is a great hobby... ;-) Mark Riley Antelope, CA Return to table of contents

I already have >a mash/lauter tun and this pail is kind of small for a fermentor. What >can I use this for? decoction mash? decorative planter? milking cows? i think you might be able to make a grant out of it, if you can drill a hole in the side near the bottom and affix a valved outlet. this piece of equipment is used at the outlet of the lauter tun during recirculation. basically it allows you to keep the output of the lauter tun running at a constant flow rate while you recirculate. depending on the quantity of liquid and grain in your mash, it allows you to maintain the level of the liquid in the lauter tun at whatever distance above or below the grain surface you desire while vorlaufing. judging from the dimensions you gave, it would probably hold nearly five gallons. this is plenty of capacity for a typical five gallon batch, and would be enough for even a 10 gallon batch. if you wanted to get fancy, you could even heat it *gently* from the bottom to keep the mash liquor warm as you recirculate. if you do use it as a grant, run a hose from your lauter output to the bottom of the pail to avoid splashing during recirculation. additionally, you could use it as a small open fermenter for 3 gallon batches. you might be able to make a flotation tank out of it. you could do all three, actually. for a flotation tank, you may want two valved outlets. since stainless is a relatively poor heat conductor, it wouldn't be an ideal "turn on the heat and let it go" decoction vessel, but you could use it if you kept an eye on it and stirred often. i have a very thin bottomed stainless pot for decoctions and it's not a huge hassle. if it has handles, that's even better. sparge water reservoir? put a valved tap on that sucker and you could do nearly anything with it. brew hard, mark bayer Return to table of contents
Date: Fri, 31 Jan 1997 16:24:03 -0300 (GMT-0300) From: Jorge Blasig - IQ <gisalb at elmer.fing.edu.uy> Subject: Wheat malting and wheat and extract recipe Dear Friends: I am planning to prepare a new batch of homebrew using my malt extract and wheat malt. I have prepare a couple of batches and did it good (the second one is better than the first). Anyhow, my beer did not have nice head retention. It presents good carbonation and head, but retention is poor. At least, this is my opinion. Taste, flavor and aroma are good, though I do not have any other homebrew to compare with. I believe I will improve head retention in my beer if I use wheat malt . However, there is no chance to obtain wheat malt here, so I need to malt it myself. I will have no problem to obtain raw wheat and will malt it if I can get the correct procedure to do it. I wonder if you can send me some information on malting procedures, in particular on wheat malting. As you know, my malt extract composition is: maltose 45-55%, dextrins 20%, proteins 5-6% and xBrix 80-83 (1.47 specific gravity). I have used a recipe with 5kg of extract (OG 1.055), ale yeast and got a FG of 1.010 and a alcohol content approximately 6% in volume. IBU is approx. 25, using Northern Brewers for bitterness and Cascade hops for aroma. I had some problems with temperature during the second batch. Temperature was around 25 to 30C during fermentation and I wonder whether I will obtain better brews when temperature decreases. I would appreciate if any of you suggests me a recipe using wheat or wheat malt and this extract. I will use the recipe you suggest for my next batch. Thanks. Jorge Blasig Return to table of contents

Description: Gambrinus has re-introduced an old German malt style called "bruhmalt" under the name Honey Malt because of it's unique honey-like aroma and flavor. Adds an intense malty sweetness with a hint of red color. Color: 18 degrees L. Certainly sounds like an interesting addition to my next brew. Tom galley at sperry-sun.com Return to table of contents

There have been several posts about having a sticky mash, due to grains like rye. If you were to put several pounds of barley malt than add corn, wheat, or rye, than on top of that add the rest of the barley malt, would it help or make it worse? _________________________________________________________________________ Arnold J.

I plan to put a tap on >the front of it to dispense my beer from cornelius kegs. Question: how >do I figure out where to drill the hole for the tap shank without >drilling into the cooling coils? Ray, I just got a similar freezer, and am in the process of doing the same. The best way of doing this is to drill into the lid, where there are no coils. You have two options. 1)Drill on the front face of the lid (usually about 2 inches high) doing this puts the tap at a reasonable height, and still allows you to fit the kegs in, without having the taps in the way. -or- 2)Buy chrome columns and top mount them. I just ordered 2 columns, with faucets, for $165 each. Each one has 2 faucets, allowing 4 beers on tap. If you do top mount, realize that the freezer is constructed with thin sheet metal, and support, plywood works well, should be used inside the lid. Also, don't buy a cheap thermostat, if it stops working, how can you pour frozen beer? Best of luck with the modification.

Date: Fri, 31 Jan 1997 12:15:20 -0800 From: Charles Rich <CharlesR at SAROS.COM> Subject: Forecasting Final Gravity Regarding "hot" fermenting (75-80F) a sample of pitched wort to predict a batch's FG Dave Burnley says: > You used the correct word "approximation". It may well be that the higher > temperature fementation will go to a lower FG than the lower temperature > fermetation, depending on the yeast, OG, etc. Besides it is unnecessary. If a lower temp ferment 'overlooks' any sugars (what else would account for a significant difference in gravity) sugar test strips will indicate the same unfermented sugars. So whether using test strips or a fast fermented-sample you have the same result; you know you have some unfermented sugars. In practice I find very good agreement between predicted and actual FG's **to the resolution of a hydrometer reading** (emphasis mine). A hot ferment might be a little more complete than my batch ferment mainly because I don't always need/want to wait for the batch to ferment the last little bit, but I know pretty well what fraction of potential gravity I'm trading off.

I'm not sure if these >carboys are up to the heat stress or not. Do it quickly, you shouldn't be holding a flame there long enough to really heat up the glass. Simple measures to keep your yeast clean are good things. On a yeasty note-does anyone know what strain of yeast used in Mad River Brewing's "Jamaica Brand Red Ale"? I made a starter form the dregs of one bottle, more out of curiosity as to their viabililty than intention to use them...but after watching the starter take off (and taking note of a delicate fruity aroma), I decided to use it in a batch of an all-Columbus IPA. It brought the 1.072 wort down to 1.015 in a week (65-68 F), and is dryhopping now in the cellar. Good to have the HBD back...let's keep the focus on the beer...

Strand" <sstrand at saul.u.washington.edu> Subject: Inverted fermentation In my quest to eliminate the secondary fermentation and cut down on washing up and other labor I am going to try inverted fermentation. Rather than the available commercial set ups for this (Brewcap and Fermitap), I am going to make my own stand for an inverted 6.7 gal carboy. The stopper will be clamped on and a long tube will go to the bottom (top when inverted) to allow CO2 to escape and a short tube at the top (bottom when inverted) will allow me to pull off the yeast when the fermentation is completed, preventing autolysis and overexposure to residual cold break trub. I'm going to add another intermediate length tube to permit me to sample during the fermentation. Can anyone offer some advice?

Our last 3 batches have had less than expected starting gravities. For all 3 we used "bulk" pale malt as the base. A porter with 6 pounds, a spice ale with 6 pounds, and an Octoberfest with 8 pounds. The original gravities were 1.033, 1.030, and 1.020!!! respectively. The first two tasted just fine, if a little thin. The fest is still fermenting. What gives?

Recently, lacking sufficient jars, I tried ordinary 12 oz. beer bottles with good results. I'd worried a bit about the seals on the bottle caps withstanding boiling temps. but, after one month at room temp., there's no problem with the worts. Method was the typical canning method- boil bottles, drain breifly and fill while hot with boiling wort, cap (I didn't preheat the caps) and process for 30 mins. in a boiling water bath. A caveat: be careful around hot fluids- particuliarly when capping the bottles of hot wort since the bottles you use probably weren't designed for this service.

My plan was to put it a pot of cold water and over 45mins-1 hour bring it up to ~170degF, treating it like Crystal or chocolate malt. I have heard two descriptions of the flavor that Rye imparts; some have described it as dry, others as sweet. I am sure this is due to different ways of treating the rye. Does anyone have experience which one you'll get by just steeping as a specialty grain and what quantity of Rye would a good upper limit to use this way? Also, could someone reproduce (even off-line) the recipe for Old Peculiar from the latest edition of Zymurgy (Old Ales are the cover story)? Extract and all-grain if possible.

I have been fortunate enough to inherit a home made SS pot. It is just over 8 gal. It has been welded along the bottom 360 deg., as well as, vertically where the top section was welded together to make a cylinder. This pot was used many times to steam C.B. Blue Crabs. It has sat for at least two years. When I found it, there was some slight surface rust around the welds. I cleaned them with a small stainless brush, all the rust was removed with little effort. I am concerned that this may be a "bad" pot to use as a brew kettle... Is this the case? Can I just clean and dry it thoroughly after I brew to prevent the rust forming? Any assistance with this matter would be greatly apprec -iated! I intend to brew my first batch of beer with it using extracts, and a full 5 gallon boil...

Date: Sat, 1 Feb 1997 08:51:57 -0800 From: Sharon/Dan Ritter <ritter at camasnet.com> Subject: planispiral chiller results I used my newly built "planispiral" wort chiller yesterday on a batch of special bitter. (For anyone who hasn't been following the planispiral chiller thread, it is basically an immersion chiller made of copper that is wound into a tight spiral - think of a heating element on an electric stove.) I admit to being somewhat skeptical of the claims that this design would eliminate the need to agitate. But, it works! My chiller is configured so that about 1/2" of wort covers the coils - in other words the chiller is suspended at the TOP of the wort. My wort chilled from post-boiling temps to 65F in 25 minutes (no stirring!). In another 15 minutes it came down to a pitching temp. of 55F. I cool my tap water before it enters the chiller with an ice bath - I'd guess the water enters the chiller at 45F. During the chilling process I could feel the temperature differential on the side of the pot. The bottom of the wort coiled first, gradually moving toward the top. I now have an extra half hour in my brewing process that I can devote to something other than hovering over the coiling wort. Very cool!

In Dec I brewed a couple of California Common style batches--my first ever use of lager yeast. I used one and a half quart starter of 1.040 (probably over kill, but it kicked off like a son-of-a-gun). Primary fermentation was 5 days at 65-70 F, secondary was three weeks in basement at 45-50 F. I primed using 4 oz of corn sugar, bottled and put the bottles back in basement. Three weeks later, I tested one--FLAT! A week later--still flat. A couple of days ago I moved the bottles back to warmer temps in hopes of someday having carbonated beer. Now for the neophyte question--I thought lager yeast liked it cold? The yeast-faq says #2112 ferments well to 62 F. Is that up to 62 or down to 62? Was I just being impatient? I will now humbly bow before the monitor and await enlightenment from the masters ;) TIA Al Clement CClayworks at aol.com Return to table of contents

Date: Sat, 1 Feb 1997 12:35:11 +0000 From: spankstr at pe.net Subject: Filtering Flattus Hello out there! I have what may be a stupid question, but here goes anyway. I have been extract brewing for close to two years now, with much of my product being consumed by me. I have never really had a problem with gas and bloating until my last two batches. It's really bad! I have tried the gas-x, etc., but find no relief. I have read that the yeast ferments substances in your bowels, thus causing the extra wind. Would filtering the beer help in this situation? If so, what size (microns) would be the best? Has anyone out there fooled around with Diatomacious Earth filtration? I was wondering how D.E. would work. I have a DE filter on my pool, and have a endless supply of DE (and it's cheap). I can't bear the thought of having to give up my brew for a commercial beer just because the wife doesn't wan't to sleep in the same room with me anymore, although I have thought of giving up the wife too but, considered that too expensive.

Date: 01 Feb 97 14:50:23 EST From: "David R. Burley" <103164.3202 at CompuServe.COM> Subject: CO2 purge Brewsters: Val Lipscomb asks a question I asked myself many times, especially when purging cornies: > For my question of the day-I always purge my 5 gallon carboy with CO2 > when I rack to secondary. I've always used 15 PSI for about a minute. > Is that enough?? Am I wasting my time and CO2? Here's how I answered it for my needs: Psi is unimportant. Volume of CO2 per unit time X time is what is important. The real question is, "How many volumes of CO2 do I need for a given container volume?" You can determine your volume for your equipment by taking a 3 or 4 liter botte full of water. Invert it in a sink or large bowl of water. Put your gas tube in the neck and turn on your CO2 and measure how long it takes to empty the bottle of the water. This will give you the gas flow rate. Assume that your gas flows at the rate of 1 liter per second on your particular settings. A five gallon carboy is 20 liters. Assume that at any instance the gases are perfectly mixed, the CO2 is going in the bottom and pushing out the current mixture ( not quite true, but 5 gallons is a small volume and the gases are turbulent) If the carboy or cornie is open to the atmosphere, at the end of 1 second the mixture of gases will be 19 liters of air and 1 liter of CO2, At the end of 2 seconds it will be 19 X (19/20) air and 19 X (1/20) + 1 liter of CO2, etc. Air is 20% oxygen as you know. If you do this calculation as a method of approximation you find that once you have pumped in 100 liters (5 carboy volumes) of CO2, the oxygen content in the gas is about 1000 ppm. This is about a minute and a half of purging at 1 liter of CO2 per second. If you rack the beer into the bottom of the carboy without splashing and let it push the gas out you will have very little oxygen in your beer. To give you an idea of the curve shape: CO2 - liters Oxygen - 1000 ppms Container Volumes 0 200 0 10 120 0.5 20 68 1 40 24 2 60 8.8 3 80 3.6 4 100 1.1 5 Using the right hand column makes this a useful table for all size containers if the above assumptions are applicable. This is important when racking to cornies if you are going to force carbonate cleared beer or when moving beer into a cornie after filtration, since the beer is at its most sensitive to oxygen with no yeast around to protect it. However,when I rack into my secondary, my beer is still fermenting and I do not bother to purge at this point, since the combination of dissolved CO2 being released and an actively fermenting yeast population will prevent the oxygen from doing damage. In this case, I don't think you need to bother purging your carboy. I do, however, minimize splashing by racking into the bottom of the carboy.
