(Or maybe my imagination.)" I've noticed the more "foaminess" too... I believe it may have to do with increased nucleation sites (hop particles) in the brew. I would doubt that it's an infection since the hops, if anything, drop the pH even more... If you're using a muslin bag (with T-90's), try switching to a tighter weave cotton drawstring bag that has been sanitized in boiling water or vodka prior to adding the hops to it. You may also notice, that the need for some type of weight is now necessary... Possible choices: stainless steel rod or bearings, ceramic or glass marbles. I prefer the marbles/bearings when working with a carboy's narrow neck, since they move around enough so that removal is easiest. Return to table of contents

Almost approaching a serious answer. "marbles in a dry hop bag" seems to be a technique that's been used as long as home brewers have dry hopped, and I haven't heard any complaints yet......"marbles" made out of baked clay (this may predate many readers) or the material "marble" (as in rock) would not be a good idea.

As long as you take care in pouring in the sparge water you are fine. The danger comes when you pour too briskly and starge digging holes into the grainbed. When I first got rid of my sprinkler system I kept a very close eye on the top of the grainbed to determine just how vigorously I could pour without causing holes in the bed. As it turns out, the pour does not even have to be all that gentle if you move your hand around as you are pouring. cheers, -Alan - -- "Brewers make wort.

It's actualy two real words: Fob -- (noun, akin to the dialectic German Fuppe, meaning pocket) a chain, strap, or ribbon attached especially to a pocket watch. Fob -- (verb transitive, from the Middle English fobben) to cheat or deceive. Often follwed by the preposition "off." To offer something bogus as genuine: to fob off forgeries on some unsuspecting soul. What this has to do with beer or brewing, I do not know (unless one was fobbing off spurious theories on innocent brewers). Jim Larsen Brewer and pedant Omaha Return to table of contents

I would rather use 150 >proof ethanol, but I have never found any on sale for a reasonable >price. 150 proof ethanol (70% abv) is the standard reccomendation when using alcohol as it is the most effective concentration. I buy a quart of Everclear (grain alcohol) at the local liquor store and dilute that to 70% with water. For those of you contemplating using alcohol as a sanitizer, shy away from any alcohol which is not meant for drinking (as if Everclear ever was ;-) because it will either be denatured alcohol or isopropyl, both of which are not natural to beer and may effect the flavor of your beer. Use that for wiping down table surfaces, keg connectors, taps, etc... If you want a slightly more effective sanitizer (especially good on stainless surfaces) then add about 3-5% phosphoric acid. I'm not sure if 3-5% is the optimum concentration for phosphoric, because typically hydrochloric or nitric acid is used in the lab - but these acids aren't good for stainless steel's health. The addition of acid lowers the pH which increases the effectiveness of the solution and broadens the range of what it will kill. Plus, it's more "natural" to beer. Spray it on and just let it evaporate. Long shelf life in a closed container. Great to use on rubber stoppers, working surfaces, etc... >I bought some hydrogen peroxide for pickling brass and it was on >sale for 50 cents a pint. It seems to me that I could use this as a safe >sanitizer as long as I didn't get it into finished beer or anything else >that you want to protect from oxidation. The pickling solution you made was probably 1 part H2O2 to 2 parts vinegar, right? This is peracetic acid and is an effective sanitizer as well. Again, the acetic acid in the vinegar lowers the pH just as in acid-alcohol. This one is nice to use since the ingredients are readily available at the supermarket or pharmacy. Commonly used in spray form, but only effective for a short time after being mixed. >I use iodophor for normal sanitation. I worry about getting it into >small yeast starters. I feel that it might hurt the yeast. It also >won't last in an airlock. I'm with ya, Mike. My large flasks and small jugs are too big to fit in the pressure cooker, so I've gotta sanitize them chemically. I always use iodophor to do the job and if time does not allow for air drying, I use cool boiled water for a rinse. I have never trusted iodophor residue even though I know it is diluted when the vessel is filled and will have at worst, an insignificant effect on flavor or yeast health. Carpe cerevisiae! Glen A.

Perfectly good question, but I, for one, was one vacation. Glad you persisted. While the conventional way of reducing diacetyl is with a higher temperature diacetyl rest, I seem to remember from discussions here several years ago that some German brewers actually do reduce the temperature of a cold fermented beer to reduce diacetyl levels, or perhaps it was that they just fermented it very cold the whole way, like maybe 42F? A search of the archives may be useful http://hubris.engin.umich.edu/cgi-bin/dothread. Here is what George Fix wrote in Brewing Techniques http://www.brewingtechniques.com/library/backissues/issue1.2/fix.html : "Diacetyl production and reduction are strongly influenced by temperature, and the rates for both increase as temperature increases. Thus, an ale fermented at 20 degrees C (68 degrees F) typically has a higher diacetyl peak than, say, a lager fermented at 10 degrees C (50 degrees F). The rate of diacetyl reduction, however, is much higher in the ale than in the lager, which is why most lager brewers prefer to get diacetyl levels below 0.10-0.15 mg/L at the end of the main fermentation. Some additional reduction occurs in cold storage, but at a very slow rate. For this reason, some brewers raise the temperature of a cold-fermented beer to 20 degrees C (68 degrees F) for a brief period following the end of the main fermentation, a practice that is usually called diacetyl rest. "One alternative is the so-called Narziss fermentation. In this procedure the first two-thirds of the fermentation is done at 8-10 degrees C (46-50 degrees F). During the final third of fermentation, the temperature is allowed to increase to 20 degrees C (68 degrees F), after which the beer is transferred to cold storage. Another alternative is to add freshly fermenting wort (kraeusen) to diacetyl-laden beer in cold storage." Hope this helps.

Wait don't tell me. The beer foams right? Is there a way to tell the difference between too-short beer foam and too-long beer foam?<< Right, too long of lines and the beer foams. The way to tell the difference is too long and the beer exits the faucet as foam already, too short and the beer exits with too much force and foams when it hits the drinking vessel. At 22 lbs I'd expect that beer to balance and pour correctly with 10 feet of 3/16 ID hose. That is using 2.2 lb drop per foot of hose; some people recommend using a "drop" figure of 3 lb/ft, then it would be a 7.3 ft hose. Rather than starting to chop up your lines you can test this by cranking up the pressure to around 28 to 30 lbs, if it pours better then the lines are too long. But too long of time at that pressure and the beer will overcarbonate; that is just to test to see if 2.2lb/ft works with your beer lines. Yes fob is a real word. A fob is easily described as one of those leather key ring-thingies that has the logo of the manufacturer on it. The way it became applicable to beer is that older bottling lines used a hicky that was shaped like a key fob to agitate the bottles so they could cap on foam. The fob was spring loaded and located in the path of the bottles immediately before the capping station; as the fob slipped off the bottle that was passing by, it slapped the next bottle in line, the vibration raised foam. The noun describing the thingie that did the action has become a brewers-verb that describes the action done. NPL Return to table of contents

Hi Mike - one way to get rid of the foam is to only use 1 ft of line between the tap and the disconnect, and then bleed off all but a couple of pounds of the CO2 when you serve it. I've found that beer loses carbonation very slowly, even without pressure on it, if it isn't agitated at all and there aren't any nucleation points in the keg (I left an airstone in the keg once and it lost CO2 in a hurry). Plus, you can always top it off with CO2 if you aren't going to drink it for a while, or if it has lost a bunch of CO2. Another thing - take apart your tap and clean it regularly. It only takes a few weeks for that yummy mold to build up in your tap and create a lot of beer turbulence. Dan in Minnetonka Return to table of contents

Schultz" <d2schultz at qwest.net> Subject: Diacetyl II Since lagers can include diacetyl rests by increasing the temp to the 60F range, I would suspect that yeast re-absorbtion would likely occur better at warmer temps. Since a yeast 's activity decreases with temperature decrease, it is probably safe to assume that some reabsorbtion of the diacetyl occurs even at lower temps. It'll just take longer. The key is to make sure your yeast is still active at the cold temps. Crash cooling does not bode well for the buggers. Some afterthought: When lagers are going through a diacetyl rest, the yeast also have a small supply of sugars to continue to eat upon. If all the sugars are gone as with bottled beers, will the yeast continue to work on the diacetyl assuming they are still viable?
