Norm Pyle hat trouble with a line that Al K wrote about Iodophor, specifically wheather or not it was 12.5 ppm free Iodine or 12.5 ppm titratable Iodine. In my original post about it I indicated 12.5 ppm titratable Iodine for a no rinse sanitization. This equates to 1/2 oz per 5 gallons or 3 teaspoons. This is from Ecolab's trade literature on Mikroklene, their Iodine based sanitizer. -Lee Bussy | The Homebrew Television Workshop Presents: | leeb at southwind.net | The 4 Basic Foodgroups...

Date: Thu, 22 Dec 94 09:12 EST From: "Lee A. Kirkpatrick" <WPSSLAK%WMMVS.BITNET at VTBIT.CC.VT.EDU> Subject: two questions: carboys and bags I've received some very helpful replies to some questions I've posted recently about brewing techniques, so thought I'd ask for advice on a couple of other issues. I've been extract- brewing for a couple of years and have been very satisfied with my results, but I'm looking to improve my technique in various ways. Here are the questions: (1) Until recently I've been using a simple, single-stage process with a plastic fermenter, but I finally broke down and bought a 5 gal. carboy to use as a secondary (for all the obvious reasons). How important is the fill level in the carboy when I rack the beer to it for secondary fermentation (or just storage until I have time to bottle)? My understanding is that one advantage of the carboy is that you can fill it to the bottom of the neck (in the secondary, not the primary), thus minimizing the air space and the surface area to reduce contact of the beer with oxygen. However, does this matter much, or is the important thing just to get the beer off the layer of spent yeast and into glass? The first batch I racked to secondary didn't fill the carboy quite this high, and I'm wondering if I should make an adjustment in the future to ensure that when I get to the secondary my fill line is at the neck of the carboy. (2) I just discovered grain and hop bags, and it was like a religious experience. I've previously used adjunct grains by slowly heating in the cookpot (or second pot) and straining them out when the water begins to boil; to remove hops, I've poured the concentrated wort from the cookpot through a strainer into my primary fermenter. The latter is a real nuisance when I use hop pellets because they clog up the strainer. And, in any case, this process results in all sorts of splashing and a big mess. So, in my last batch I put my adjunct grains in a grain bag and used it like a tea bag, and was impressed with how convenient this was. I later emptied the bag and put my pelletized finishing hops in it. (The grain bag was a little large for this purpose, but worked fine.) It now seems to me that if I got some hop bags and did all my hop additions this way, and also used a grain bag for the adjunct grains, I wouldn't have to use a strainer later on, which would have a number of other advantages. I like this a lot. My question is: Is there anything else I need to know about the use of grain and hop bags to use them properly? How important is it to run extra water through them to extract the last of the goodies from the grain or hops? Does a bag work as well if you're adding finishing hops for only a minute or two, or is it important to stir the bag around to ensure extraction of all the goodies? Are there disadvantages to using bags that I haven't thought of? Thanks for your replies. Private e-mail probably best. --Lee Kirkpatrick wpsslak at wmmvs.cc.wm.edu Return to table of contents

Nor can I get it from 122 to 150. I even >add full boiling water! My best results have been when I start with a >very small amount of water and a thick mash. Then adding hot water >produces the greatest movement. But once I have more water in there, >then it becomes harder for further movement. I have experienced the same problem. I use an insulated Sankey keg for a mash tun with a perforated screen on the bottom. It does a good job of holding a temperature, but raising the temperature after mash in is tough. I have tried steam infusing through the valve under the mash screen. This did raise the temp. To move from 150F to 170F it took 25 minutes and requires stirring to avoid hot spots. I was concerned about HSA with this method. It seams like allot of bubbling is going on as the steam moves through the mash. I do mostly infusion mashing at 150F +-. I pretty much gave up on trying to raise the mash to 170F for mash out. Since the main purpose of mash out is to get the grain bed warm enough for the 170F sparge, I just started sparging with 180F water to compensate. I have considered building a RIMS setup to raise the temp at the end of the mash and also for the occasional step mashes. I have hesitated to move on this since the only way to obtain the electronic temp controller is to build it from scratch.

I'm sorry that it doesn't' have a cute name. Maybe we should have a name-that-yeast contest here on the HBD-something PC, obscure, that gives only the slightest hint to its true origins ;-) The culture was purchased a few months ago at the request of a micro who's name I don't recall at the moment. I don't have much experience with this one yet,although I am doing my best to try to convince people to use it. Jeff Renner (among others) has, and will probably speak up. Here is what I know: Max. Temp. 37.0#161#C, Min. Temp. 13.4#161#C, Optimum Temp. 32.0#161#C. moderate attenuation, fast fermentation, high flocculation. From my experience it does not produce much top crop. The taste seems rather neutral, but this could be that I am comparing it in a split batch with Shepherd Neame and Gales cultures, both of which are far from neutral. 1187 appears to be excellent primarily from mechanical standpoint.

The staff was quite helpful and prompt. The lab tech that I talked to was interested to know that water chemistry was important in making Real Beer (not tm BBC). Most of their inquiries, I gathered, were from health nuts and fishkeepers. I mentioned that I also kept fish, and he replied that the water in my area was treated with chloramines. The use of chloramines is increasing all over the country, from what I understand. Apparently chloramines are not removable by boiling. I do have chemicals that will convert them to something that the bacteria in the fish tank can eat, but I doubt that I want them in my Real Beer. Any suggestions on what I can do to remove them from my brewing water? (I'm an extract/speciality grain brewer right now.)

Michalski, MD" <michalski_jm at rophys.wustl.edu> Subject: Anderson valley products Recently a local supermarket has begun carrying products from the Anderson Valley Brewing company in Mendocino California. I initially tried their Barney flats oatmeal stout which was incredible! Well worth the gold medal they received last year. I've also tried their Boont amber American style pale ale which was equally terrific. It had a dominant caramel aroma and flavor with a great hop aroma and flavor. Their porter was also very good. I noticed when drinking the porter that the beers appear to be bottle conditioned. I am curious if anyone has had success cloning these beers. If you have been succesful, did you use the yeast sediment in the bottles to make a starter? Does anyone have any other information about the hops, and grain bill they use? These are great beers but at $4 for a 22 oz. bottle I would like to take a crack at brewing my own! JEFF M. MICHALSKI michalski_jm at rophys.wustl.edu Return to table of contents

From reading other posts on this (Jack Schmidling, Maribeth Raines) it seems there is tremendous variability based on how you do it. I think you have to analyze the beer to know what you've got. I put one bottle in a 2 qt. pot, if I had put 2-3 bottles in the same pot I don't think the reduction in alcohol would have been as great because the surface area to volume ratio would be smaller. Based on some lab work I've done in the past on volatile compounds I know this ratio can have a big impact on evaporation rates. You will have to lose a fair amount of water to significantly lower the alcohol content. That's why I included the volume loss in my post. Another question was did I correct for evaporation of water. The answer is no correction was needed. The GC measured concentration of alcohol of each sample taken right out of the pot. What was analyzed is what I would have drank had I taken the solution and carbonated it. I did not take the heated liquid and add water back to the original volume. But this brings up an easy short cut - heat your regular beer for awhile, then dilute with water to lower the alcohol content further. I also want to re-emphasize that the absolute numbers in my post shouldn't be taken as is. The original alcohol content of the pale ale was listed as 6.1%, but I know from the gravity readings (1.043 OG, 1.006 FG) that this was high. Even with 20-30% error on the high side the alcohol levels were clearly reduced to much lower levels than the original concentration. If I had more time we could maximize the accuracy of the chromatography, but this was a favor in a very busy commercial lab so I don't think I'll be doing much more work.

Then I take the iodine and put a few drops on the tile close to the mash liquid but not directly in it. Tilt the tile and let the iodine slowly run into the mash liquid. Take your reading from the interface of the iodine and mash liquid. This is kinda what it looks like: (use a mono-spaced font to see this) ---- ---- - --- Mash --- ||--Iodine--- - ----------- ||----------- - ------------||------------ ------- -- Judge the conversion by the color between the || where the liquids meet.

The answer seems to be that the krauesen dries to the bung/glass interface, effectively glueing it in place. It doesn't release before the glass breaks, in some cases. I've never seen this problem myself, thank God. ** Kevin Fons writes: >Can anyone create a WATER.FAQ, it would be very useful. There doesn't seem to be great interest in doing this. I suspect it is because nobody is much of an authority in this area, or perhaps just because it's a boring subject. Questions on water often go unanswered, so I'll give it a shot: >Hardness 143ppm Moderate hardness, I would say. >Ph 7.5ppm Meaningless. The pH of the water has no bearing on the pH of the mash or runoff. Buffering action of the mash ions controls the pH. BTW, it isn't "ppm". pH is used like a unitless number, although it somehow stands for the hydrogen ion concentration (a log of it, hmmm, I'm grasping at straws now...). I _do_ know it means "power of Hygrogen". I think. >Chlorine 1.2ppm Pretty normal, or at least similar to mine. >Calcium 96ppm Again, moderate hardness. The difference between the 143 ppm total hardness, and the 96 ppm calcium hardness is mostly magnesium, or so I'm told. >Floride 1.1ppm Also similar to mine. >Chlorides 16ppm ? >Sodium 7ppm Nice and low. It is always good to have less of something, than too much of it, as it is easier to add ions than subtract them from water. >Which additional measurements should I request? I would ask for numbers on carbonates, sometimes called alkalinity, or temporary hardness. I'm guessing what they call "Hardness" above is only permanent hardness. You might also try to find out numbers on sulfates. The bottom line is you want as much info as possible on the ions that contribute to permanent and temporary hardness: calcium, magnesium, potassium, sulfates, carbonates, and bicarbonates. As far as adjustments, do nothing at first, and take pH measurements of the mash and runoff. You probably don't need to do anything to your water, since it seems to be pretty "middle of the road". I'm no expert in this area BTW, not by any stretch of the imagination. I highly recommend you read Dave Miller's "Complete Handbook of Home Brewing". He has a very good chapter on water that explains things much better than I can. And he's probably right, to boot! Cheers, Norm Return to table of contents
Date: Thu, 22 Dec 94 11:27:12 TZ From: Daniel Cook <dancook at microsoft.com> Subject: Damn that Chlorine! Fellow brewmakers, Admittedly, my routine for cleaning bottles has usually been to stick as many as I can in my plastic bucket, add water and bleach, and leave it overnight. Sometimes I am busy and overnight becomes next week. Typically I need to do this twice to clean enough bottles for one batch, so I'd calculate I've done this 16 times with one plastic bucket, which is also my primary fermenter. My most recent batch, a nifty Christmas ale with nutmeg and raspberry, was first tasted on 12/17, and it seemed a little young but certainly on its way. Last night, 12/21, the 2nd tasting was hopeless. Like a wheat beer gone bad. After much reading, I suspect CHLOROPHENOL. I've seem to recall postings about chlorine leeching into the plastic of a fermenter and then back into a fermenting wort. If thisis true, I'm certain to experience it. It does seem like my last few brews have tended towards that phenolic taste. Should I just get a new bucket and use the old one strictly for cleaning? My guess is Yes.

Nothing definite, but I heard speculation that it was a $$$ thing, Matt's wanted to up the cost of doing business with the Boston (tm) Beer Company and BBC balked. Considering that Stroh's has quite a bit of excess capacity, it probably wasn't too hard to get them to cut a deal. RE: the beers that BBC is having brewed under contract for the Oregon Ale and Beer Brewery, Jim Larsen is correct. I heard an ad on the radio today which claimed that the beers are produced in Lake Oswego, OR, (home of Saxer). I am not sure why the bottles indicate the brewery is in Portland.

Doing a full boil (the whole batch) is not necessarily bound to all-grain brewing as many extract brewers believe. Doing a full boil will give you better hop utilization, better hot and cold break formation, less darkening and less caramelization. It does, however mean that you need to use some kind of force chilling (wort chiller, sink full of ice, etc) or you won't be able to pitch for hours and hours. If you have a 8 or 10 (or larger) gallon kettle, then I recommend you build yourself a chiller and go to full boils. ******* Kirk writes: >In HBD 1609, Algis R Korzonas writes: > >>>Body is what I'm after here.

No. There are soluble proteins in CaraPils and since all the crystal malts add some head retention and mouthfeel, I take this as an indication that there are, indeed, small proteins (the good, head-retaining, body-improving ones) in crystal malts. ************** Allen writes: >In HBD 1609, Al Korzonas wrote: > >>MOST of the body of a beer comes from proteins not dextrins. > >Please quote your source(s) of this information.

Here's my source: Date: Wed, 10 Jul 91 12:34:04 CDT From: gjfix at utamat.uta.edu (George J Fix) Message-Id: <9107101734.AA11342 at utamat> Apparently-To: korz at ihlpl.att.com Status: R Al: Both unfermentable dextrins (alpha-glucans) and proteins Contribute to a beer's body. Of the two, viscosity measurements show that proteins are more important. This can be directly verified in small volume brewing experiments. Try a normally mashed all malt beer as the control. Then do a "diat" version with a long and extended low temperature mash. The finished beer will have almost the same protein spectrum, but much less alpha-glucans. It will be stronger in alcohol content but thinner in body. This illustrates the effect of dextrins. Next do a third brew where, say, 15% of the malt is replaced with a dextrin corn starch. The latter has no proteins and approximately the same carbohydrate structure as crystal malt. Compare the three test brews taking their different alcohol content into account. A point I forgot to mention in my last message is that the main reason I use crystal malt is for color and for its special flavoring. Mashing crystal malt is the best way I know to get both. Other procedures that have been put forward --e.g.,boiling-- tend to extract husk constituents that I find unpleasant in finished beer.

I I think that exploding carboys are a rare occurrance, but they still can be a hazard. No, I don't think anyone except the people using the *new* BrewCap *imitator* are actually "wiring down" anything onto their carboys. Note that the mess is no smaller when the blowoff hose/airlock ejects. The three times that my blowoff hoses have clogged, the pressure had built up quite high before ejection: 1-to-3 gallons of highly carbonated, sticky, partially-fermented beer all over the ceiling, walls and floor. No, you definately don't need the glass to break to make a big mess with a clogged blowoff tube. ************ Norm writes (correcting me): >This 5 ppm of *free* iodine can be obtained if you have 12.5 ppm of >*titratable* iodine. Does this sound better? Yes, I should have wrote 12.5 ppm *titratable* iodine. The "phor" in iodophor stands for "carrier" and my understanding of the way that it works is that the carrier releases *free* iodine as it is depleated. Hoppy Holidays. Al.
