All I can say is that this method produced a beer that I found had a pretty good hop character but was woefully underhopped as far as bitterness is concerned for the style. I've been considering giving FWH another go and so have been reading up on it. I now realize that the recommendation is to use the flavor and aroma hops for FWH and not the bittering hops. Also, the literature claims that although there is a greater total IBU contribution through the use of FWH, the nature of that contribution is different and doesn't lead to overhopping. My one foray (so far) into FWH would appear to support this. In regard to your particular question... While it would be interesting to know the degree to which the 'bitterness' of bittering hops is affected through the use of FWH (and if anybody has quantitative info about that rather than my qualitative data I'd love to hear about it), on a practical level it would appear that FWH should be done w/ the flavor/aroma hops and that the bittering hops should be used as usual to hit the target IBUs. How's that for drawing conclusions from a single data point? :-) - - Joe - ------------------------------------------------------------------------ Command, Don't Demand. - ------------------------------------------------------------------------ Joe Shimkus shimkus at sw.stratus.com Stratus, VPG TPF/FIO 508/490-6705 (ph), 508/460-0397 (fax) - -------------------- Stratus disavows my opinions. --------------------- Return to table of contents
Date: Tue, 17 Dec 1996 10:36:38 -0500 (EST) From: Todd Kirby <mkirby at bgsm.edu> Subject: Re: Depressed Homebrewer Bob, I also have a well and had similar infections my first few batches. I was confident in my sanitizing and concluded it was my water as well. After switching to Iodophor, all my problems were eliminated since I was able to eliminate the rinsing step. You don't mention your sanitization technique, but if you're not already using Iodophor, I highly recommend you give it a try. It's fairly cheap, easy, and faster than most other sanitizers. Others mention rinsing with boiled water or even cheap beer, so maybe you could try those methods as well (or other no-rinse applications). Good Luck and Happy Holidays, Todd Kirby. P.S. I'll be thinking of all you homebrewers as I'm downing a few Guiness in Ireland over the holidays! Can't Wait. Return to table of contents

I >haven't had it checked in about a year or 2 but in my first 2 years of brewing >I did not get one infected batch. Now almost every batch gets infected. I am >thinking of going out and buying bottled water for my brewing. >Does anyone have any words of wisdom? Bob, I also use well water from the next door neighbor, since my house is newer and is on county water. However, I boil the well water for 10 minutes as well, unless I am doing a full 5 gal mash. Then I only do a couple of gallons, usually a few nights in advance, and place the water in sanatized plastic milk jugs with caps. This way I always have some sterile water around. Bacteria from the soil can fall/creep down the well casing and into the water. There are a lot of factors that affect this, and it may not affect you or your family by drinking it, but the beer however.. I also do not know what your santization techniques are, but I sanatize EVERYTHING in iodophor. Bottles, tubing, airlocks, etc. sometimes twice, if I touched it. Worst case, I rinse with boiled water. Yes, everything has a nice brown tint to it, but I really don't care that everything look clean, I care that it IS clean. I hope you find this info helpfull. I posted this to HBDV2 for others who may have similar problems.

I would like to ask those who _use_ or have knowledge of plastic, what would be an appropriate plastic 'kettle'? What do most people use? The reason I ask this is that the working temperature of polyethelen is listed at only 88C and the only containers I have found are 1) HDPE barrels which have been used for other things and I would have to try clean them. and 2) LDPE roto-moulded buckets. Material 1 is stronger I believe, but the container is 1/3 the thickness. How well would either of these materials tolerate boiling wort(temp ?) inside? And would the material become so soft as to worry about any fittings used in them failing? Please don't bother telling me that: stainless or copper is the only thing that should be used, the wort will scorch using an imersion heater, the kettle will melt when placed on the stove/cajun cooker especially if it covers two burners...

The linear coefficient of thermal expansion of 304 stainless steel is 9.6 microinches per inch per 'F. Since I didnt know the exact dimensions of your pot other than it holds 50L, I took the cube root of 50 to give me a vessel of 36 cm on a side. This converts to 14.5 inches per side and when you multiply 9.6 x10^(-6) x 150F, you get a change in length of .0209 inches, which when cubed results in a change in volume of less than a drop in the bucket. So, by my mash calculations assuming a Mash efficiency of 85% which gives a yield of 32 ppg for the Pale Ale malt, 22 ppg for the Roast Barley and 28 ppg for the Flaked Barley and a final volume of 5.75 gallons, that would yield a calculated OG of 1.046. You got 1.055. BUT! You did not collect 5.75 gallons of runnings you sparged with 4.4 and collected an unknown amount and then added an additional gallon in the boiler. After the boil had cooled you measured 1.055 for 5.75 gallons per your calibrated stick. I theorize that either: a. you had a lot of trub still in suspension that really upped your gravity reading. or b. Your calibrated stick is way off or c. you were actually reading 4.75 gallons which works out to an OG of 1.056, based on my previous OG calc.

Bob, first go back through your process step by step concerning sanitation of equipment. If you are doing primary in plastic, maybe somewhere along the line the container has become scratched and now does not clean up properly. Possibly the problem is in the bottling process, caps, or bottles. I can't get behind the idea that the problem may be your water unless something drastic has happened to the aquifer supplying the well. I have been brewing with gravity flow spring water inwhich I know live newts and frogs (sometimes - they keep down the cricket population) without a problem.

Date: 17 Dec 96 12:45:44 EDT From: Bob Bessette/PicTel <Bob_Bessette at smtpnotes.pictel.com> Subject: Thanks for all of the infection responses... Fellow HBDers, I knew there was another reason why I enjoy brewing so much. Not only is it because when I do brew an un-infected beer it is a glorious experience but it is the sensitivity of the home-brewing community which makes this such a rewarding hobby. I received MANY responses from my brethren on why I am getting infected brews. There were a wide range of responses and I will try to synopsize here. One thing I did learn was that I was not alone. Many homebrewers have had "infected" brews consistently until they had modified their process or sanitizing procedures. Here are some of the suggestions that I received: > Soak bottles in bleach solution overnight and use the dishwasher afterwards making sure the heat button is turned on. (I do this...) > Replace all siphoning equipment including the bottling bucket (including spigot). (I will do this...) > Do not let any unboiled tap-water (in my case well water) get in contact with the cooled beer. (I still do some rinsing with the tap water, this could be a problem) > Use iodophor and do not rinse hoses etc with the tap water. Iodophor will dry without rinsing with water. (I will do this) > Use rubber gloves during the brewing process. (I will buy some) > Ferment only in glass, not plastic. (I only ferment in glass, never plastic) > Use only liquid yeast. (I only use liquid yeast) > Do not dry-hop with fresh hops, always boil the hops to sanitize first. (I boil my hops first) Out of the above suggestions I think that using iodophor rather than rinsing with my well water may be the solution. I am constantly rinsing with my tap water even after the colling down of my wort. I will rinse the hoses and use them to siphon from my cooling bucket into the carboy. This is unfiltered well water being introduced to my cooling beer. I do this all the time and was never really warned by others probably because they don't have well water. One email I got from Todd Kirby really hit home: >I also have a well and had similar infections my first >few batches. I was confident in my sanitizing and concluded it was my >water as well. After switching to Iodophor, all my problems were >eliminated since I was able to eliminate the rinsing step. You don't >mention your sanitization technique, but if you're not already using >iodophor, I highly recommend you give it a try. It's fairly cheap, easy, >and faster than most other sanitizers. Others mention rinsing with boiled >water or even cheap beer, so maybe you could try those methods as well >(or other no-rinse applications). I think the steps I will take are the following: 1) Purchase all new tubing, and a new bottling bucket. 2) Buy iodophor and only use this as a rinsing agent from cooling of my wort to bottling. I think I've pretty much been doing everything else as far as sanitation is concerned. It just makes sense that the untreated well water, even in very small quantities(rinsing of hoses), may be introducing bacteria into the beer. I want to thank all of you for your responses. I will keep you updated on my next batch. YES, I will be brewing again. If not for all of your very helpful,caring posts I don't know whether I would've jumped back into brewing so quickly again. Thanks again and hopefully in the near future I will be brewing the beer that I am accustomed to... Cheers, Bob "formerly depressed brewer" Bessette Return to table of contents

I've been thinking of starting the policy of doing my secondary fermentations in 5-gal kegs, but I had a few questions about how to modify them for fermentation use. 1) I understand that when used as a primary, I should have a blowoff tube. Is this really necessary for a secondary? Most of my batches, unfortunately, do not equal exactly 5 gallons, so there is a little room on top for any krausen that might build up. 2) What's the suggested way of attaching an airlock onto one of the valves? 3) Do I have to modify my "liquid out" diptube, i.e. cutting it off shorter? Should I leave this tube in while fermenting, or leave it out until I'm ready to rack off the beer? 4) I've read conflicting opinions on the effect of the physical size of the fermenter (i.e. tall and skinny) and the ability for yeast to flocculate, etc. Anything I should be worried about?

I just wanted to second this observation, and make a suggestion for anyone who may be looking for a mill to use in their brewery. I have used a Corona in the past, and would agree that it gives good results when used correctly. The best thing I have found to use, however, is an antique mill used to grind flour or coffee. These are the big old ones with a large motor in the back that turns a grinding wheel against a stationary front, adjustable wheel. (just like the Corona) You will usually see them with a large hopper feeding the grinder from the top. There is a knob for adjusting the crush on the front of the grinder. (Also just like the Corona) The one I have was actually used for grinding coffee. It was made by Hobart somewhere around 1930. (The knob on the front says "adjust for type of brew before grinding" cool - huh?) Anyway, I got mine for $25, and it is indestructable. A friend of mine uses an old flour grinder that looks exactly the same. I have found the crush produced by these grinders to be ideal, as well as cheap and efficient. (Turn on the motor, and feed it grain) Grinding the grain is now a joy, instead of a chore. If you can find one of these, grab it. You won't be dissapointed. Mike H. Portland, Or.

After many infected batches and a lot of time spent searching for the cause, I finally thought to disassemble the drum tap on my bottling bucket. I found the parts coated with a foul- smelling crud. My beer was fine out of the fermenter, but getting infected as I bottled it. I was sanitizing the bucket with bleach followed by a boiling water rinse, but either those liquids were not reaching all parts of the inside of the tap, or they were not they staying in contact long enough by just running them through the tap. When I started taking the tap apart and cleaning it each time, the problem was solved. Eventually I got tired of fooling with it, bought a bucket without a tap, and went back to siphoning. Maybe a different type of spigot would have worked too, but I didn't try that. Steve Christiansen Beaverton, OR steven at sequent.com Return to table of contents
Date: Tue, 17 Dec 1996 14:25:23 -0600 From: Algis R Korzonas <korzonas at lucent.com> Subject: Sticke Jeff writes: >First, Al piqued my interest in V2 #3 when running though beers he dry hops >he wrote "Sticke (a dryhopped version of Duesseldorfer Altbier)". Sounds >great! Al would you have a grain profile and hop/yeast suggestions? Sure, but forget about entering it in the AHA Nationals ;^). Sticke is a "special" batch of Duesseldofer Altbier which is brewed as a reward for the regular customers. "Sticke" in the local slang means "secret" and the tie-in with the beer is that there is no big ad campaign when the beer is on-line. If you are a regular, you get it, if not, then you probably lose out. It's brewed once or twice per year by the various brewpubs in Duesseldorf and each has their own way of making the beer special. Commonly, it is slightly higher gravity and has more IBUs than the brewery's regular Altbier and is often dryhopped. Based upon what I've read and spoken to brewmasters in Duesseldorf, Spalt hops are commonly used (Spalt and Spalter Select are the only two hops used by Zum Uerige). Standard Altbier is mostly Munich malt to about 1.050 OG, fermented cool and lagered cold. It is not strongly attenuated, so it has a hint of sweetness, but it is so intensely hopped that it can taste dry. It should not be decidedly sweet -- it must be refreshing. Typical hop rates for the most traditional Duesseldorfer Altbiers are 40 to 55 IBUs and they don't have any flavour hops added (although some flavour is bound to slip through with those kinds of hopping rates). Sticke is slightly higher in OG, say 1.055 or 1.057 perhaps. If you can do a decoction mash, use 99% Munich and 1% black malt. If you plan to do an infusion mash, I'd go with 89 to 94% Munich malt, 1% black malt and 5 to 10% DeWolf-Cosyns Aromatic or Weyermann Melanoidin malt. Hop the heck out of it: 55 to 60 IBUs, all for a 60 minute boil and all Spalt if you can get it. I would suggest dryhopping with 1/2 oz of Spalt. If you can't get Spalt hops, I would use Saaz, Tettnanger or Hallertauer. As for yeast, I really like the Wyeast European Ale #1338, which, to my taste, seems hauntingly like the Zum Uerige yeast. Ferment it at about 60F and then, after fermentation, slowly cool to 45F for a few months of lagering. I would add the dryhops for the last three weeks of lagering. Roger Deschner tells me that the Zum Uerige yeast is quite prone to temperature shock, so this is why I suggest *slowly* cooling the beer to lagering temps. Bearing this in mind you should really try to get the starter and wort around the same temperature. I, personally, have not experienced any temperature shock problems with this yeast, but I'm always very gentle to yeast in that respect, so I'm just going on suspicion. Coincidentally, I had a Zum Uerige last night. It was my last bottle, purchased at the brewpub. I was celebrating the sale of my retail store Sheaf & Vine Brewing Supply. The flavour is still very clear in my head. Yum! Al. Al Korzonas, Palos Hills, IL korzonas at lucent.com korz at pubs.ih.lucent.com korz at xnet.com P.S. To save myself a lot of private email and since I have absolutely no financial ties to the business now, let me take this opportunity to answer a few questions. Sheaf & Vine Brewing Supply's retail "branch" is now going to be called "P. T. Barley Brewing Supply" and will still be located inside Mainstreet Wine and Spirits in Countryside, IL. They currently plan to keep on all the current malts, hops and extracts and will probably be adding a few more. They may do mailorder (as I did back in 1992 and 1993) but not at least until after the Christmas rush. I sold the store because I need more time to be a better husband and to actually be able to brew more than once per month (although it usually was two or three simultaneous batches!).

Date: Tue, 17 Dec 1996 15:44:30 -0500 From: Tim Martin <TimM at southwest.cc.nc.us> Subject: When to stop sparging question (Tim Martin) Hey Neighbors, Sorry to interrupt the no sparge thread but I am still trying to get the old sparge technique down. When I mashed and sparged recently my technique was to keep adding sparge water to my hot liquor tank until I collected my predetermined amount. My concern with this method is leaching tannins from the grain. I noticed that the last gallon of runnings were quite clear, which probably means no more sugars were being extracted so I was just basically running 170 df water through my grain and to top it off I forgot to add gypsum to the sparge water. I know that it is recommended to keep checking the gravity and stop at 1.010 or taste the runnings and stop when you can longer detect any sweetness but this seems like a real PITA. I suppose if one were to follow this method one would stop at this point and top off your collection tank with water. Is anyone still with me? Question 1) why would I start extracting tannins just because I reach the magic number of 1.010. 2) why does one extract tannins at all 3) would anyone take an educated guess whether I probably extracted tannins with that last gallon of clear runnings 4) is there an easier method to determine when to stop sparging that I have over looked 5) I'm I being too anal. The no sparge looks interesting but the calculations look to complicated. Well thanks for listening and any help would be appreciated. Y'all have a cool yule! Tim Martin Cullowhee, NC.

What I did was use what (I think)is called a "french whip," a common kitchen utensil [I think, since I know nothing about cooking, and the only thing that get me into the kitchen is the need to be there to brew], which I used to beat the cooled wort vigorisly, before syphoning it into the primary. There was three inches of foam on top when I started syphoning. When the primary carboy was about half full I pitched in the yeast, as the wort dropped in from the top. I had done a full boil, and had cooled the wort with an emersion[can't spell either] chiller down to about 70 deg. F. The frementation was the most vigorous to date. OG was about 1.046 and it was down to 1.014 in 24 hours. I pitched yeast which was 2 packs of Edme dry yeast, rehydrated in water only for about an hour as the boil was going on. Is beating the **** out of the wort like this advisable? Seemed to work good this time... Boy does my beer taste good after commuting to work and back on my bicycle 32 miles round trip!

Date: Tue, 17 Dec 1996 16:53:57 -0800 From: homebrew at ix.netcom.com Subject: Tiny bubbles Hello again, I was wondering if someone could comment on the following observations: When priming and subsequently bottle conditioning homebrewed alcoholic beverages, I have noticed that the CO2 bubbles produced are of the very, very fine persuasion. Does force carbonating said beverages produce a larger bubble of CO2 (and thus a bigger head)?? Additionally, at room temp the head is full, dense, rich and has great staying power. However, under refrigeration, there is virtually no head at all. It was explained to me, per the comments I recieved via the RCB regarding the head on my homebrew (pun? no pun?), that when refrigerated the CO2 has been absorbed into the liquid and when opened and poured is not expressed as readily as the room temp beer. So here is the question: When beer is force carbonated, does one add "additional" CO2 so that when a cold beer is poured, a full, dense, rich head forms?????????? Do any of you homebrewers experience the same condition??? Can this be resolved with say additional priming sugar (I use the published 3/4C corn sugar or 1-1/4C DME), or extended conditioning time (i.e. two weeks then consume)???? Maybe someone could explain or point me to a suitable reference. Kevin Return to table of contents

Anybody care to comment on the various yeast slants available, and/or your experience with them? I recently began using yeast cultured off of slant, and have had mixed results. I have been very happy with Yeast Culture Kit Co. yeasts. So far, I have used their Irish Ale and Belgian Ale yeasts (the Irish yeast is my new "Stout yeast of choice"). Both fermented stronly and quickly and flocculated well. Both yeasts have made positive contributions to the flavor profile. I have not had success with Brewtek's yeasts. I have had three batches (using two different slants) with the same problem -- poor flocculation, high final gravity, and a "solvent" like taste (I have never had these problems before). All three batches were made using Brewtek yeast slants -- their American Ale #1 and British Pale Ale #2 specifically. The only variable I can see that is responsible would be the new yeast strains. Currently, I have a brown ale aging in the keg, hoping that the aging time will reduce the thin, solvent-like flavor. I would like to hear any feedback about these or other yeast slant manufacturers.

Date: Tue, 17 Dec 1996 19:23:10 -0700 From: "Maribeth_Raines, Asst_Prof" <raines at radonc.ucla.edu> Subject: Shelf-life of yeast on slants Most of the published references on storage of yeast ( including those written by Barbara Kirsop from National Collection of Yeast Cultures) suggests subculturing slants after 1 year. I routinely check the BrewTek slants that are sold for viability, contamination, etc. After six months the viability is still well over 65%. I have successfully resuscitated yeast after 2 and 3 years on a slant. Viability does vary between different strains. There are also other factors which can also will affect the shelf-life such as the media on which they are stored and the amount of exposure to air. In our hands (and using BrewTek media), brewing yeast remains viable for at least a year. MB Raines-Casselman raines at radonc.ucla.edu Return to table of contents

Date: Tue, 17 Dec 1996 20:50:14 -0800 From: Sharon/Dan Ritter <ritter at web.camasnet.com> Subject: Decoction mash I'm attempting my first decoction mash after 30 all-grain batches - "Why has he waited so long?" you're probably asking. I've been in a blissful infusion mash routine but unhappy with the lack of background malt flavor in my pilsners. Here's my plan - any suggestions would be appreciated. (I'm using De Wolf-Cosyns pils malt for the primary portion of the mash (80%). DWC Aromatic, CaraPils, and Munich make up the remainder.) Strike temp at 145F. Rest for 20 minutes. Test and adjust pH if necessary. Pull 3/4 (or more?) of the thickest part of the mash. Heat decoction to 155F. Rest for 20 minutes. Bring decoction to a boil for 25-30 minutes. Add decoction back to main mash and stabilize at 155F. Rest for ~60 minutes. Add infusion of boiling water to reach mash-out temp of 168F. Sparge as usual. Call fire department to clean kitchen. I modeled this procedure after Marc de Jonge's micro FAQ on decoction mashing - <www.alpha.rollanet.org/library/decoctfaq.html>. What do you think? Will this procedure noticeably darken the final color of the beer? I'm right at the upper edge of the color limit for this pilsener if I were doing an infusion mash.

As with many tools it has to be set up >properly, > >I sold the Malt Mill cheap. I am back to using the poor old Corona >with wonderful result. Perhaps Mr. Noonan needs to have more attention >paid to his writing. When "Even Newer Brewing Lager Beer" comes out, Noonan will probably devote more space to roller mills. While you may be perfectly right, those percentage points you're getting aren't what's driving the market. A reasonably priced mill that's simple to adjust for a good crush, and can be driven by a power drill out of the box, is rightly considered a homebrew advance. The market will probably continue to move in that direction. The double-crush method works well if you really want ideal results with the inexpensive roller mills, but they're quite acceptable with a single pass as well. - -- Alex Santic - alex at salley.com Silicon Alley Connections, LLC 527 Third Avenue #419 - NYC 10016 - 212-213-2666 - Fax 212-447-9107 http://www.salley.com Return to table of contents
