Date: Tue, 22 Nov 1994 12:35:12 +0100 From: Fredrik.Stahl at mathdept.umu.se (Fredrik Stahl) Subject: Colour Formulas Hello everybody, I hope you can help me out on this one. Looking at colour formulas in my different articles, books and programs, I realized that there seem to be at least two different methods to estimate the colour of your brew from the colour potential of the grains. Dave Miller (in The Complete Handbook of Home Brewing) uses: potential * modifier * %grain * OG / 40 summed over all the grains, where potential = colour potential of the grain, unit L modifier = factor giving the darkening of wort during boil, estimated as 1.25 %grain = percent of total grain weight OG = original gravity of wort in points 40 = gravity of laboratory test wort used to obtain the potentials. Darryl Richman (in The Brewer's Worksheet, Excel spreadsheet available at Sierra) uses: potential * grain_weight / total_volume summed over all the grains, where the potential now has the unit L * gallon / lbs. MPM (sample excel spreadsheet found at Sierra, origin unknown) uses the same as Darryl Richman, except for a correction if the colour estimate is >10: corrected colour = 14.6713 * Log(colour_estimate) - 4.6713 Here are colour potentials for some grains from the different sources: Miller Richman MPM ???? L*gal/lb L*gal/lb - -------------------------------------------------------------------- English Pale 3 3 3 Roasted Barley 530 397 500 Chocolate 350 397 400 Munich 10-20 5.5 13 2-row 1.6 2.0 1.7 Of course, the colour potential may vary for a specific grain but Richman's values seem to be generally lower. (Please don't show this to the people at the mathematical statistics department - they'd beat me blue and yellow and I'd end up competing with the Swedish flag :-{O> ) Well, sorry about the length of this. It may not be so important (the colour is just a very rough estimate anyway) but I'd really like to get things sorted out. Response by private e-mail is fine - I'll post a summary.

He called it "Rick's Wicked Ale." I would like to say that I used Rick's recipe with only minor variations and at bottling time last night, it tasted GREAT! I can't wait to dig into it. I would highly recommend Rick's recipe, which I have included below (with credit to Rick of course). The only change I made really was to dryhop with a little leftover cascades I had around the house.

A few months back I asked anyone with suggestions for a Pete's wicked Ale clone to comtact me. I received a few recipes, but as usual, I adapt them according to my own intuition. I respectfully submit, then, my attempt to clone Pete's. I call it... Rick's Wicked Ale 8.5 lbs American 2-row pale malt 1 lb Crystal malt (40L) 1/2 lb Cara-pils malt 1/3 lb Chocolate malt 1/2 ounce Cascade hops (boil) 1/2 ounce Brewer's Gold hops (boil) 1/2 ounce Cascade hops (finish) 300 ml yeast starter- Wyeast 1056 Mash grains in 3.5 gallons of water at 75 degrees Celsius (brings temp to 67 degrees C). Hold at 67 degrees C for one hour until conversion is complete. Sparge with 5 gallons of water at 77 degrees C. Boil sweet wort for one hour with boiling hops. Turn off heat, add finishing hops and steep for 15 minutes. Cool, strain into fermenter, bring volume up to 5.5 gallons. Pitch yeast. ***Notes*** Someone suggested I use Chinook hops, but my bottle of Pete's said that it was made with Brewer's gold hops. The o.g. was 1.050, f.g. was 1.015. After two months in the bottle, a side by side comparison was made, and I proudly proclaim that my beer comes close. The chocolate flavor was very fresh. Others suggested dry-hopping, but I preferred the chocolatey aroma to the beer in this case. Return to table of contents
Date: Tue, 22 Nov 94 09:27:24 est From: Robert_Ser at ceo.sts-systems.ca Subject: A Beer In Search of a Style (or Name) CEO file contents: Greetings, fellow HBDers!, Following Ulick S.'s recent request for more posts to the HBD, I thought this might be a good time to submit my first post... I hope you'll find my question amusing, if not challenging. Last week I brewed, well, a beer. Kind of a leftover thingy... After buying an 8 Kg (about 18 pounds for the metrically challenged) bucket of Edme light LME at the incredible price of 30$ Cdn, and brewing a bitter and a brown ale two months ago, I found myself with about 1.5 Kg (3.25#) of leftover malt. I also found a beer kit can (Armstrong's Pilsner) that had been lying around my basement for about 9 months. My wife, who was getting tired of having this mostly empty bucket taking up a lot of room in the fridge, suggested that I combine the beer kit can with the leftover Edme LME to use up the old malt and make room in the fridge... "No!" I cried out in complete horror! "I can't combine English malt with a Pilsner kit! That would ruin the style!"... But to no avail: she convinced me (she has quite a pretty smile and can be very persuasive ;-) ). I wanted something 'German' tasting, and this is the recipe I came up with: For 5 US gallons: - 1 3.75# can of Armstrong's Pilsner beer kit (well hopped) - 3.25# of Edme light LME - 3/4# of Munich malt (steep in 150F water for 30 mins) - 1/2 oz of Hallertauer hop plugs (bittering at -60 min) - 1/2 oz of Saaz hop plugs (flavour at -15 mins) - 1/2 oz coriander at -7 mins (yes - I fell for that coriander thing. I brewed the day before Al K. mentioned that the whole thing was somewhat of a joke) - 1/2 oz of Hallertauer hop plugs (aroma at -2 mins) - Wyeast 1338 (European Ale yeast) OG: 1048 Here is my problem: I have no idea what style of beer this is! Not bitter enough, too light colored and too hoppy for an Alt. Can't be a lager of any kind because of the yeast I used... Would someone be kind enough to help me out? If this is nothing else but an 'Ale', how about helping me come up with an interesting name for it? (I don't know... Leftover Ale? Empty the Fridge Brew?)

Date: Tue, 22 Nov 94 09:39:06 EST From: Allan Rubinoff <rubinoff at BBN.COM> Subject: blow-off In HBD #1585, Steve Tinsley (stinsley at ti.com) writes, regarding the use of a blow-off hose: >you are blowing off active >yeast through your hose (this applies only to top-fermenting ale yeasts). >A few months ago, I broke my primary fermenter, narowly escaping major >lacerations, and had to purchase another one.

Any rebutalls >to this line of thought? Do the "bad hop oils" really make a difference >here? This seems to be a religious issue among homebrewers, but I'll throw in my two cents. I ferment 3-gallon batches in a 5-gallon carboy, with no blow-off. I used to use a 3-gallon carboy with blow-off, but switched because I thought the head retention of my beers was suffering. I don't know whether you lose much yeast using a blow-off, but I believe you lose a lot of the proteins responsible for head retention. The krausen that forms on the top of the beer during fermentation is the same stuff that makes the head on your finished beer. During blow-off, you lose a lot of krausen. I have not noticed any detrimental effect on the flavor of the beer since I made this change. (I brew only ales, so the beer never sits on the trub for more than two weeks; perhaps it takes longer for the off flavors to develop.) And though it may be just coincidence, my beers have had better head retention since I stopped using a blow-off. I know most commercial brewers use blow-offs, but I wonder where the hose is attached to the fermenter. I suspect at the bottom, not the top. If that's so, this would mean that trub would get blown off, rather than krausen. Allan Rubinoff rubinoff at bbn.com Return to table of contents
Date: Tue, 22 Nov 1994 09:55:12 +0500 (EST) From: Edward Bockman <ebock at telerama.lm.com> Subject: Low S.G. I attempted to brew a white beer this weekend, and am afraid that my mash didn't go too well. The mash contained 4.5 lbs of German Pilsner, 4.0 lbs of unmalted wheat, and .5 lbs of oats. Mashed in at 120F, rested for 20 minutes, converted at 150F for 1.5 hours, and mashed out at 176F. The reason I let the conversion go for so long was that it didn't look like anything was happening. The sparge (5.5 gallons) went very quickly. After boiling, etc. my SG was only 1.028. I'm pretty sure that I did not get good conversion. Does anybody have an explanation... Was enzyme concentration too low? This is the first time I used the Phil Mill to crack the grains... The husks all looked cracked, but could it have left the inside to whole? Any suggestions welcome.

Date: Tue, 22 Nov 1994 10:33:41 -0500 From: dsetser at nttfsrv.gsfc.nasa.gov (Dave Setser) Subject: Kegs to Bottles I've just purchased all the equipment necessary for kegging my homebrew, and love the convenience. The one problem that I've encountered is that of bringing samples to club meetings, friends, etc. Does anyone know of a method whereby I can condition my beer in the keg, and then use the keg to fill a limited number of bottles? Common sense tells me that if I just dispense to the bottle and cap it, I'll have problems. I'd appreciate any response - the more detailed, the better. Thanks in advance!

Date: Tue, 22 Nov 94 10:43:58 EST From: uswlsrap at ibmmail.com Subject: Old extract / persistent bubbles - -------------------- Mail Item Text Follows ------------------ To: I1010141--IBMMAIL From: Bob Paolino Research Analyst Subject: Old extract / persistent bubbles Peter at BCIT asks about old cans of extract: I wouldn't use them for beer, particularly not for a batch I cared about. Now, if you were going to make a batch of generic non-descript beer for a party of non-beer types, you might use it if you were willing to risk the time and effort that it may or may not be very good. If the people who are drinking it usually swill down Buttwipers/Miller/Coors/Molson Light, they might think it's great even if it isn't your best effort. That'll have to be your call, of course. But here is a possible use for them--yeast starters. Boil up a can of this stuff (with some hops), diluted to give you about 1.040 or so, and can/bottle the wort. I don't go to the bother of canning jars and that process, although it's said to be the preferred method. When I make a batch of starter wort to put away for future use, I half-fill (okay, 1/2 to 2/3) sanitised 22 ounce bottles and cap them. I keep them refrigerated, but that probably isn't absolutely necessary, particularly if you "can" them. When I'm ready to get some yeast going, I pull out a bottle of wort (far enough in advance to let it warm to room temperature), flame the top of the bottle,and pour the wort and the yeast (either from the plastic vial it's sold in or yeast previously saved from primary fermentation) into a sanitised 1/2 gallon bottle. After aerating it, I cover the mouth of the bottle with a few layers of foil As for using _old_ extract, it ought to be okay for that purpose. But look at/smell/taste the extract or the wort you make from it. If it seems off, get rid of it. - - - - - - - - - - Bruce at Virginia asks about the airlock that won't stop: It's hard to know what to tell you without knowing more, but here are a few things to consider. 1) What's the fermentation temperature? Warm liquids don't hold CO2 in solution as well as cooler ones. 2) What's the gravity? Is it still pretty high or is it in the expected range for a finishing gravity for the style you're brewing? If it's low enough, go bottle it. 3) Do you have an infection or a wild yeast fermenting what should be unfermentable? Does it taste/smell okay? Other comments: don't follow instructions on a can of extract. Brew it right instead! Don't use corn sugar in your beer unless you have a good reason to use it. Use two cans of extract, or supplement it with some plain dry or liquid extract. Don't prime by putting a spoon of sugar in the bottle. Instead dissolve the corn sugar in boiling water (I use 1/3 to 1/2 cup for a 4-5 gallon batch. 3/4 cup is typically recommended, but I find that too carbonated. YMMV.) and put that in your bottling bucket as you begin to rack from secondary. You'll get more consistent results. Hope something here solves your mystery.

Date: Tue, 22 Nov 1994 11:01:15 -0500 (EST) From: "nancy e. renner" <nerenner at umich.edu> Subject: Priming, blowoff (From *Jeff* Renner) There have been several questions lately about long bubbling secondaries, high FG, over/under priming, etc. Let me offer my ideas. First, batch priming is more precise than adding sugar to each bottle. It does carry some risk of varying carbonation levels due to poorly mixed priming solution. I boil my priming sugar or malt in a couple of cups of water and let it cool (covered, in a water bath sometimes) in an oversized container while I set up my siphoning and bottling equipment. Then, mmidway through racking from my secondary to my priming container, I stop and siphon a few cups beer into the priming solution, then siphon this into the priming container, then finish racking. This avoids much of the problem of thermal and density stratification. Then I gently stir the primed beer. You don't have to worry about oxidation. The beer is probably giving off CO2 from the agitation and this blankets the surface. Besides, O2 will be quickly metabolized by the yeast. As far as waiting until the bubbles completely stop, don't bother unless you want to age the beer anyway (and I think there are advantages to this -clearer beer being one). Once a minute can go on forever. Two causes that come to mind are (1)the slowly fermenting sugars that some extracts have (or some mashes produce), and (2)wild yeasts that may slowly ferment some complex sugars. Either way, you may want to cut down on your priming sugars if you expect to keep these beers a long time. Over time, they will become drier and more carbonated. Unless your bottles are weakened from abuse, the worst that will happen is gushing. Adam Rich mentions a Laaglander beer that has stopped at 1020. This is typ[ical of this extract. It is good as part of a recipe for increasing final gravity/residual sweetness, but if used 100%, you may get an unbalanced beer. Eric Jaquay primed with a cup of blackstrap molasses and hates the flavor. IMO, blackstrap tastes like what it is, the waste product of sugar refining. If you have to use molasses, use one of the milder types, and a lot less than a cup. Good luck with the flavor going away. I think you are in a better position to find out if it does than anyone else. **** About blowoff. I like it. I think it may reduce my bittering slightly, but it seems to result in cleaner tasting, smoother beers. I like to adjust my final volume in the primary so that I get less than a cup of lost beer. Most of the brown residue sticks to the top of the carboy or Sankey. Soakiong in bleach removes this. By using a one inch hose in the neck of a carboy, I eliminate any danger of clog and explosions. Potential clogs are from whole hops. When I ferment in a Sankey, I attach a small hose to the stopper with a short piece of broken racking tube and make sure I havent siphoned any large hop pieces. Cleaning a large hope can be done with a carboy brush, but I alway soak either size in bleach water. They always seem clean. Then I boil them before reuse.

Date: Tue, 22 Nov 1994 11:08:16 -0500 (EST) From: Jim Busch <busch at daacdev1.stx.com> Subject: RE:yeast stuff Randy writes: <I have used (and still do) trub to start a next batch but only from the primary. Just a nit, but while there is some trub in the bottom of the primary, we are a lot more interested in yeast. Some wash the trub away using "sterile" water or acid. <As I understand it, aeration is most important to achieving a quick and healthy start to fermentation. Which leads to more yeast cells and a faster healthier fermentation. It is also a significant influance on flavors in the beer as a result of yeast products, esters, alcohols, etc. Norm writes: <I've had this question for quite some time about stepping up your starters. <What's the point? For ales OR lagers, why bother stepping up the starter <size? If my final goal is two quarts of starter, I'll just make a two-quart <starter and pitch the Wyeast right into it. Going from a pint to a quart to <two quarts (for example) seems like wasted effort to me. If the answer is <"lag time in the starter", I can see some concern but not a big one. What am <I missing? The classic approach is to step up in 10-1 increments. So a Wyeast pack of 50 Ml should be stepped into 500 ml. This will result in more yeast cells per volume of sugar, which gives quicker growth/ferment. I dont see a big difference in doing a 20-1 step with 50 ml. John writes: <If you know what you are doing, and how to handle a high pressure O2 <cylinder, and realize how much O2 you are putting into your environment, <then I say go ahead and aerate your wort this way. I dont want to beat this dead horse too much, but I do want to emphasize that you absolutely have to have a O2 regulator on your tank. Once you have this, it is as easy as a CO2 tank to control. These regs do come in both psi scales for welding and Litres/min for flow rates. Al asks about stoves for brewing. This is something I have been looking into. Many people I have asked like the Superb, produces 35K. I use a burner I fabricated out of a line of burners from Solarflow in Ohio. I have also used cajun cookers but the deflector plate is important in heat control as is a lot of stirring when mashing. Jim Busch Colesville, Md Return to table of contents

Any rebutalls >to this line of thought? Do the "bad hop oils" really make a difference >here? No rebuttal, just a remark that an experiment I did and described about a year ago in the HBD, supports your line of thought. I pitched my yeast starter into a 6 1/2 gallon batch of SG 1.041 Special Bitter, then racked into two 5 gallon carboys, filling one to about 3 inches from the top. Active fermentation was visible in both batches after about 10 hours and the filled batch began blowing off after 12 hours. After 10 days (66F) the non-blowoff batch was finished with a SG of 1.011, while the blowoff batch was still at 1.020. I bottled the non-blowoff batch and reracked the blowoff batch and let it sit in secondary for another 10 days, then bottled with a FG=1.013. As far as "bad hop oils" there was only negligable differences in the two beers - some preferred the blowoff batch, others the non-blowoff batch, while I really couldn't tell the difference. Since then I have always used my 7 gallon carboy for primary and will use a blowoff hose if I either fill it with more than 6 gallons or have a high gravity wort. On the other hand, I feel the risk of infection using a blowoff is minimal, especially if your blowoff hose is soaked in a sanitizing solution (no need to rinse). Also, despite the longer ferment time, using a blowoff didn't hurt the beer either.

Date: 22 Nov 94 11:29:52 PT From: T1HALL at T4A.dot.ca.gov Subject: bulging extract cans You should never purchase bulging cans of extract syrup or other types of bulging containers with extract syrup. You should get them for free! The cause of the bulging is a wild yeast that was picked up during processing. >From what I understand, the store owner can remove the label or other packing information and get reimbursed from the manufacturer. This summer I managed to get two 6 lb packages of syrup that were bulging free. The first I put in the refrigerator and the next morning the soft container was still growing so I through it in the freezer that stopped the yeast cold. I used that pack in a stout and don't taste anything unusual. The second package unfortunately didn't make it to fermentation, since the carboy full of fresh wort decided the gravitational pull was too strong and turned into a slippery eel just before crashing on the garage floor like a giant pumpkin spewing its sweet honey all over the floor. It was ugly and what I missed was sticky the next day. Oh well, live and learn. Jim Hall Return to table of contents
Date: Tue, 22 Nov 1994 10:42:25 -0800 (PST) From: gbaldw at zaphod.usin.com (Gordon Baldwin) Subject: All grain process Here is my all grain brewing process. I use this process for probably 80% of my brewing. Total brew time is about 3 to 3.5 hours with a break in there for the mash. I realize there are probably lots of ways to improve this, but with this system I can turn out very good all grain ales or lagers quickly. I can even brew after work and be done in time to put the kids to bed. Materials: 5 gallon SS pot 8 gallon ceramic on steel pot zap-pap lauter tun long SS spoon Thermometer 1/2 gallon glass measuring bowl 6 gallon plastic primary 5 gallon carboy 10" strainer Add mash water to 5 gallon SS pot and bring it up to strike temperature. This is dependent on the recipe. Add the grains and add heat if necessary to bring it up to mash temperature. I usually mash at about 145 deg F. Wrap the ss pot in an old sleeping bag and go away and do something else. I start the mash sometimes before I go to bed at night to brew in the morning, or I come home at lunch and start the mash for an evenings brew session. When I am really ready to get brewing, I put the mash back on the stove and raise the temperature to about 150-155 and wrap back up in the sleeping bag. Fill the 8 gallon pot with sparge water and bring to a boil. Once the sparge water is boiling carefully ladle the mash into the Zap-Pap and add sparge water to cover the grain by 3-4 inches. Transfer the sparge water to the 4 gallon pot and put the 8 gallon back on the stove. (my 8 gallon pot almost covers 2 burners). The Zap-Pap sits on a stool and the 1/2 gallon measuring bowl sits on the floor. Recirculate about 1 gallon and then start carefully pouring into the 8 gallon pot. Turn on the heat once there is about 1" of wort in the pot. If you go slow the boil should be going when the pot is about 1/2 full. Shut off the sparge after each bowl-full until the wort is boiling again. By the end of the sparge the wort has already boiled down about 1/2 gallon and half your boil is already done. Boil for an hour. During the boil is a good time to clean everything from the mash. Near the end of the boil I start the sanatizing of the primary. At 5 minutes before the end of the boil I plop the chiller in to sanitize. When the boil is done I run the hose from the back yard into the kitchen and hook it to the chiller. Chill for about 25 minutes. Put the strainer on top of the primary and pour the wort through the strainer. This does a great job of aerating, but a lot of the break material ends up in the primary. pitch the yeast, clean up the boil pot, and you are done for the day. I transfer to the secondary after 2 days or whenever the foam falls back into the beer. That is my process. I realize there are lots of areas where HSA is a risk, but I have found that if I am careful HSA is not a problem. I have to splash a lot for HSA to be noticible. The benefits of this is it is quick and easy, and it doesn't take any expensive equipment. With the long mash the flavor profile is kind of a crap shoot, but I like it that way. When I am brewing "to style" I am a lot more careful about temp profiles and mash times. - -- Gordon Baldwin gbaldw at usin.com Olympia Washington Return to table of contents

(My There is a direct relationship between temperature, CO2 pressure and volumes of dissolved CO2 in your beer. The best discussion of this relationship (as well as explainations of how to adjust your hose lengths for a given pressure) that I've seen is in the 1992 AHA National Conference Proceedings, in Dave Miller's section. I believe that some of this information may be in the kegging FAQ -- see the header of HBD to find out how to get the FAQs. You do not have to increase and decrease your pressure if you have your hose lengths and diameters correct for the pressure you are using. 25 psi was probably too high a pressure for the temperature you had and the volumes of CO2 you wanted, but the foaming had to do with not enough backpressure from the hose/faucet. I store my ales at 54F, have a 6-foot, 3/16"ID beer hose, ending in a Cobra tap and I believe that my regulator was set to 12psi (currently, I'm using my CO2 tank for something else and had to change the setting). *********** Peter writes: >I have several cans of malt extract that I have had for about 2 1/2 years. I >am wondering if they are still okay to use or if they should be tossed. Is >there any way to tell if the extract is usable? Any tips would be appreciated. You can use it, but I suspect that it will be quite oxidized unless it was stored at near-freezing temps. I regularly use old extract (stuff that has gotten too old to sell), but just for swilling beer -- nothing that I would serve to friends or enter in a competition. The resulting beer is darker than normal for that extract and has a sort of nutty/sherrylike flavour due to the oxidation. *********** Bruce writes: >Approximately one month ago I started a batch of dark English ale using a >canned extract.

I had It sounds like either the extract you used was deficient in nutrients (corn sugar has no nutrients), you did not aerate your cooled wort enough, you used a very old, weak yeast or some combination of the above. I'm assuming, of course, that you are not trying to ferment this "ale" at 50F. Actually, some ale yeasts (like the popular Wyeast American Ale) get sluggish at temperatures below 63F. I usually bottle when the airlock rate is down to about 1 bubble every 2 minutes, which takes about 1 to 2 weeks depending on the yeast, OG and temperature. It's hard to say if your batch is done (a hydrometer measurement would help, but only if you know the expected terminal gravity -- some extracts are not very fermentable and unfamiliar brewers are fooled by the high FG). If the majority of the fermentation was done in the first week, but then there was a three-week period of slow fermentation, then I would guess that you could bottle now (has the beer cleared, i.e. has the yeast settled out?). If the ferment never quite got going, then you should probably buy a hydrometer take a reading, and send me email. If the ferment is stuck due to poor nutrition, then you can make up a good, well-aerated, 2 quart starter with some dry extract, maybe a small amount of yeast nutrient and more yeast. Once this ferments-out, dump it into the primary and let this yeast finish the sugars in your wort (you can pour off the spent starter if you don't have room for it). The only ways of knowing which extracts are high in FAN and which are not are either experience or there is an article in the next issue of Zymurgy which does give the FAN for a number of popular extracts. If the ferment is stuck due to underaeration or due to an old or lame yeast, then use the same solution as for poor nutrition, but you can probably skip the nutrient. >been the case with other batches I had brewed several years ago.

I don't recommend priming each bottle, nor should you add any more or less priming sugar. I recommend siphoning the finished beer into another, sanitized container which contains all the priming sugar (1/2 to 3/4 cup of corn sugar, boiled a few minutes in a cup or two of water) and then siphon into bottles after stirring gently. Incidentally, I don't believe there is any physical benfit from using dried malt extract for priming and corn sugar is considerably more easy to use.

Which should I use/buy? 2) When people use the 5 gallon buckets, do they have a blow-off tube into a milk jug or do they just leave the fermentation foam (krausen?) in the bucket? I read that it is a good idea to have this bubble out to get rid of some nasty off flavors. Thanks for any help, Pat Humphrey New Brewer :-) Return to table of contents
