Wort in at 200 - 210 F. i would like to use less water and get the temp of the wort lower. i have seen other posts regarding water usage in the 3 times range. what i would like to know 1) would adding another 50 feet of chiller help get temp down to 65-70 F range (water in) and also would it cut down the water usage?? i am assuming with the current set up the performance is a little low - hot water out is prehaps to cold?? 2) does anyone have the "rocket science" part - formula for modeling the flows(wort and water), lengths, temps.... etc?? thanx in advance joe rolfe Return to table of contents

Now, I don't have a 42 gallon bucket, ..... On this issue I have good and bad news to Mike, but good news to everyone else using the "immersion in ice" type chiller where the wort is siphoned into a copper coil which is immersed in ice water. The bad news is that when phase changes occur (solid ice to liquid water) the formula that Mike used, which he derived from the averaging formula Vc*Tc + Vb*Tb = (Vc + Vb)*Tt (1) is no longer valid. The good news is: the actual target temperature will be much lower than prediced by (1) due to the latent heat required to change (melt) 32 degree F ice into 32 degree water. For example, if you "mix" equal amounts (by weight) of boiling water at 212 degrees (F) and ice at 10 degrees (F) (a typical temperature inside a freezer) you get water in equilibrium at about 52 degrees (F). The formula for computing the equilibrium temperature (assuming the equilibrium state is liquid and the wort has the same thermal properties as water) is Tt = (Tb*Vb + (0.453*Ti - 73)*Vi) / (Vi + Vb) (2) where Vi and Ti are the volume and tempurature of the ice. In this formula, 0.453 is the ratio of heat capacities of ice to water, and 73 is the value for the latent heat required to change ice to water divided by the heat capacity of water. Of course, for equation (2) to have some validity, the ice will have to be constantly stirred so that the equilibrium temperature approximates what is actually occuring in the wort chiller. Also, if you initially add water to the ice in your bucket, you can approximate the effects by first modifying the volume and temperature of the "boil" (as if the water was added to it) using (1), and then apply (2) with the modified values for Vb and Tb. The bottom line is that you need only about 6 gallons of ice to reduce the temperature of boiling wort to 50 degrees F. Bill Szymczak Return to table of contents

Date: Mon, 3 Aug 92 09:47:32 PDT From: sami at scic.intel.com (Sam Israelit) Subject: A question, a warning, and ... My new arpartment only has an electric stove so I find myself in the market for a "cajun cooker". Can anyone with experience with these devices make a recommendation on performance, cost, availability, etc...? I was at a garden party last weekend and got into a discussion on the golden hops (not a brewing variety) that the owner was raising. He made a comment that I thought might be of interest to all of the hop growers on the net. It appears that when some varieties of hop vines are cut open, the "sap" (for lack of a better word) can react with the sun. If the grower brushes the hop vine with bare skin (ie, an arm) and doesn't wash off the "sap", it can react with the sun light to cause a rather severe burn on the skin (Maybe "photocaustic" is the right word, but I don't know for sure). These burns can be very painful and can cause scars. It's not the kind of thing that is going to happen immediately, though I have been told that with some plants it can occur very quickly. It's probably early still to start thinking about cutting down your hop vines, but I thought it would be worth passing on the info. This isn't something to be paranoid about, just be careful if you are like me and you don't wear a shirt when you spend the day "cutting back" the garden during the final sunny days of the season. To be on the safe side, though, I'll wear a long-sleeved shirt and gloves when cutting down my hops in the future . . . And, finally, in a recent HBD issue, Ken Johnson wrote: > If your beer quality goes down when switching to full mash beers, then > you are lame. Whoa Ken! Reach down deep and grab the reins!

Date: Mon, 03 Aug 92 09:55:23 -0700 From: mcnally at wsl.dec.com Subject: mill experiences I brewed with grain crushed in my own mill yesterday for the first time, and I'm pleased. It may seem amazing, but I've brewed lots of all-grain batches (maybe 30) and I've never had a mill. On my last two brews I crushed with a marble rolling pin (laugh away). I have a Marga Molino, fitted with an extended hopper and an output chute fashioned from some plastic scraps picked up at a local plastic store. It's fitted to a board with a hole cut through to match the geometry of the chute. The collection bucket is positioned on a shelf below the hole. I drove the mill with a 3/8" boring bit fitted to a variable-speed power drill. The crush took a little longer than I thought, but overall I did a little over 10 pounds of grain in just under an hour. For a significant portion of the time I had the mill adjusted a little too tight, so next time I'll probably finish a lot faster. Even when the mill was too tight, the crush seemed very complete, much more so than that achieved by my former source of crushed grain, the Fermentation Settlement in San Jose (which is not to bad-mouth them). The husks came through very nicely, most completely intact. I did get a lot of flower, but since the husks were there I didn't worry. When I loosened up the mill I noticed that I still got flour, but less. At mash-in, several big starch clumps formed. These I broke up with a wire whisk with little effort. The mash went fine and I had complete conversion in a little over an hour. Sparge was not unusual, perhaps a little on the quick side. When it ran clear, it ran *real* clear. The best part was that my extract efficiency was *way* better than before. The OG of the five gallons was about 64, giving a utilization of about 31. Previously, I had never gotten better than maybe 27. Thus, if you don't have a mill, get one. The Marga is OK, and I'm sure the MALTMILL is too. _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Mike McNally mcnally at wsl.dec.com Digital Equipment Corporation Western Software Lab Return to table of contents

Date: Mon, 03 Aug 92 18:08:14 EDT From: Jay Hersh <hersh at expo.lcs.mit.edu> Subject: Mouthfeel >I read the article from the Summer isue of Zymurgy by Michael Tierney on carbonation in beer titled "From Carboy to Beer Glass: A Note on Froth." A very interesting article that I am sure to read many more times. One fact he mentions in his article is that mouth feel is the word that professionals give to a properly carbontated beer that tingles on the tongue a little. My interpretation of mouth feel up to this point was more a measure of body. My question is: does mouth feel refer only to carbonation and its sensation? Hmm, for myself and other judges I know of these are both correct, i.e. mouthfeel is a measure of smootheness and fullness of the beer, and how well blended the carbonation is. In other words how the beer feels in your mouth. This is a complex sensation, and comprises an interplay of the factors of body and carbonation (poor carbonation feels prickly or sharp and "bites" at your tongue). JaH Return to table of contents
Date: Mon, 3 Aug 1992 15:20 PDT From: BOB JONES <BJONES at NOVAX.llnl.gov> Subject: Dry hoping & All grain brewing from Micah Millspaw Dry hopping, a different approach. I have recently begun dry hopping my beer after fermentation and after kegging. I take my beer filter canister and a cheap ($2) 5 micron filter put the filter in the canister and shove 1\2oz of aroma hops into the canister around the filter. I then use CO2 to push the beer thru the hop filled filter into another keg. IMHO this gives a very noticable hop bouquet and adds no bitterness, it also eliminates some of the messy problems that occur with normal dry hopping methods. ====================================================================== All grain brewing. I do it because its way way cheaper than using extracts. Malt extracts at retail prices are about $3 per pound in my area, I pay about 21 cents per pound for barley malt. As for the time it takes, my brewing equipment is semi-auto mated, but even with that I see about 4-4 1\2 hours for a 16 gallon batch. Most of that time does not require my presence, I pop into the brew house for the mash in, go eat breakfast, come back for the mash out and sparge ( the sweet wort is being pumped into the kettle as comes out of the mash tun) as soon as a boil is achieved I leave again come back in an hour make hop additions, for the rest of the boil the only times that I go near the kettle is to add hops. I do clean up the mash tun and prep the primary fermenter during the boil time but doesn't take much. I usualy get a lot of yard work done while brewing.

Date: Mon, 3 Aug 92 12:48 CDT From: arf at ddsw1.mcs.com (Jack Schmidling) Subject: N-A, The Secret To: Homebrew Digest Fm: Jack Schmidling Cynic that I am, while pondering the discussions about low alcohol yeast and exotic processes used by the majors to produce low alcohol beer, I took the insipid taste and total lack of beer character this stuff has as a major clue to the secret. Having two gallons left after kegging a batch of stout, I added one "exotic" step to my N-A process. As a review, I heat the ready-for-bottling beer to 170F (uncovered) and hold it there for 30 minutes. I then let it cool (uncovered) to 150F at which point it is below the Pasteurization temp and must be covered and cooled for bottling or kegging. I then tap this into a keg and cool it in a bucket of running water. When room temp I force carbonate it. According to Jeane Hunter's gas chromatograph tests on samples I sent to her, this results in about 1.3% alcohol. The "exotic" step I added to this batch was to add a gallon of WATER prior to kegging. We had it last night with pizza (on beer bread crust, of course) and Marilyn and I agreed that it was the best N-A we have made to date. It has a nice creamy head, tastes like stout with just a hint of coffee from the roasted barley. The N-A usually takes about a week to lose the cooked taste for the heating but this stuff tasted great after 24 hours. I have little doubt that another gallon or two of water would still leave us with more flavor and beer character than the stuff from the majors and reduce the alcohol well below the .5% level required of N-A. I also have little doubt that this is the expedient the majors use to achieve the low alcohol level. The addition of water not only reduces the alcohol level but obviously also the calories. It reduces the body and total character but the basic "taste" is not lost and off flavors are of course, reduced as well. js js Return to table of contents
Date: Mon, 3 Aug 92 21:11:59 EDT From: gkushmer at Jade.Tufts.EDU Subject: One gallon mead? I have been thinking of making a one-gallon mead from a Leatherwood honey (made in Tasmania) that my housemate brought home. I have a package of Red Star Pasteur Champagne yeast that consistently yields me good results in larger batches - but I'm questioning the wisdom of dumping that entire package into one gallon of water/honey. Meanwhile, I have in a secondary in my basement five or so gallons of mead that has been inactive for at least three weeks. It's looking very clear, yet I was thinking that maybe I could take some of the mead from that carboy and dump it in the one galloner. Would the inactive yeast from that mead work in this new environment? Or is this a bad idea? Maybe I should re-hydrate the Red Star package and dump some of it in the one-gallon carboy? I could get a mason jar, sterilize it, and put the majority of the yeast in that in my fridge. While I'm at it - does anyone have a yeast strain they like that they could recommend? And I don't mean something that one of you chemistry goons made up on your research grant :-) I'm looking for some commercial alternatives that I can get.

Date: Mon, 3 Aug 92 19:38:11 PDT From: polstra!larryba at uunet.UU.NET (Larry Barello) Subject: Diacetyl Rest question Does anyone have any parametric experience with diacetyl rests and has a good handle on what limits should be respected? I seem to recall from the Practical Brewer, that temperatures in the range of 60-65f reduce diacetyl quickly to very low values. I have a lager that has mostly fermented out at 48f. I have moved it to my Ale fermentation box (e.g. the laundry room) and it is around 62f. Since it is mostly fermented out I am not too worried about excess ester production while the yeast completes the fermentation. After it completes fermentation I plan on kegging, carbonating and lagering at 40f for a month or until it clears. Oh, I am using a Pilsner Urquell D yeast. I don't know anything more about it than that. Thanks! Larry Barello uunet!polstra!larryba Return to table of contents
Date: Tue, 4 Aug 92 13:05:41 BST From: Conn Copas <C.V.Copas at lut.ac.uk> Subject: Querying the experts Hate to do it folks, but its amateur chemistry time again. First, the reasons behind head retention. Miller states that proteins reduce surface tension of CO2 bubbles, thus facilitating retention. This piece of reasoning was also repeated in a recent Zymurgy article. This doesn't sound altogether intuitive to me. Also, I distinctly remember a physics class in which we added detergent to water in order to reduce its surface tension; yet detergent is the nemesis of head retention. So what gives? Secondly, Rajotte (in "Belgian Ale") and formation of higher alcohols. He makes a rather vague claim that yeast activity increases said alcohols, therefore oxygenation of the wort prior to pitching reduces same. From my reading of Fix, I understood the opposite to be true. I presume there are complex interactions between a variety of factors such as yeast strain and health, free nitrogen, temperature, specific gravity, fructose content, fat content and dissolved oxygen, so is it possible to state a general rule? I seem to remember one of the Beer Hunter episodes in which a brewery used a technique to promote the formation of fusel oil late in the fermentation, whereas Rajotte seems to be more concerned with what happens during respiration. - -- Loughborough University of Technology tel : (0509)263171 ext 4164 Computer-Human Interaction Research Centre fax : (0509)610815 Leicestershire LE11 3TU e-mail - (Janet):C.V.Copas at uk.ac.lut G Britain (Internet):C.V.Copas%lut.ac.uk at nsfnet-relay.ac.uk Return to table of contents

I understood >that if you mash out at 170 deg.F you raised the temp of the mash >to 170 deg.F and then keep it at this temp for some time. That's a pretty accurate description of mash out. It's done to stop enzyme activity and to help avoid a set mash. >How could it take 2 hr to run water sparge water through your >grain bed unless the sparge was stuck(set mash?). Two hours seems a little lengthy to me as well, but it is certainly possible. My first all grain batch, I set the tap on the lauter tun for the merest trickle, i.e., if I just nudged it the runoff would stop entirely. Two hours of sparging later, the runoff still measured around 1.053. Anxious to get on with it, I opened the tap, and ran the remainder of the sparge water through quickly. I've done a half dozen batches since then, each time increasing the runoff rate and carefully recording the SG and final volume. At the moment, I'm averaging 5 gallons sparge water through 9-10 pounds of grain in just under one hour, and still getting 30-32 points/pound/gallon. The plan is to keep increasing the runoff rate until I see a significant dropoff in extraction, in an attempt to achieve a good time/quality tradeoff. I mention this because of the recent thread regarding sparge times. I think it's interesting that the times reported by other net.brewers vary so much. Anyone else out there drawn this sort of correlation between sparge time and extraction? >My plan is: >Fill my cooler with grain add hot water for a final temp of 155 deg.F This is single step infusion mashing, works well with highly modified malts. >Let this sit until conversion about 1-2 hrs. I'll use the iodone test Using iodine is a good practice, you want to be sure conversion is complete. I suspect it won't take 2 hours for conversion though, especially with highly modified malt. I'd start iodine testing at 45 minutes to 1 hour. >Recirculate until the run-off is not cloudly. >Run 170-175 deg.F water(sparging?) throught the grain bed keep the water level about 1/2-1 in about the grain bed untill the run-off is not longer sweet or I reach my 7 gal. volume. I use both the hydrometer and the taste test to determine when to quit sparging, and have found that the taste of tannin first becomes noticeable around 1.020. At about 1.015 - 1.010, there is no longer any detectable sweetness, this is when I stop. Surprisingly, these three events (no sweetness in runoff, 1.010 on the hydrometer, and full pre-boil volume achieved) all seem to occur at just about the same time. >Did I discribe this right?

Date: Tue, 4 Aug 92 10:50:14 EDT From: emeeks at unity.ncsu.edu Subject: breaking up hop plugs Hi everyone, I just started using plugged hops on my last few batches, and in my enthusiasm I just have to add my $.02. I break up the plugs quite easily with a pair of sharp kitchen shears. Rather than slicing it into pie-like wedges, I take advantage of the "cleavage planes" within the compressed plug. I have found you can start a notch in the side of the plug, then peel it apart into two thinner plugs (of course, the same can be accomplished by inserting a thin, sharp knife into the side and twisting a little). Once it is in thinner sections, you can easily fold (tear if you prefer) the layers and stuff them in the carboy. Other than fresh hops, nothing beats the smell of those inner plug layers. I just get the sections small enough to fit in (with a little force) the carboy. After just a few days in the secondary, the hop plug separates the rest of the way by itself. Gee, and I couldn't understand why all the "dull" postings on breaking the inner seal of a Wyeast package!

My question is this: If I use a grain bag in my Bruheat will it support the entire weight of, say, 10lbs of wet grain (how much would this weigh?)? I'd like to pick up the entire mass of wet grain and place it into the lauter tun in one easy step. What I don't want to do is rip open my grain bag and drop (pour?) the goods onto my kitchen floor (likely resulting in happy dogs and an unhappy wife). I suppose I'm just being lazy, but then "laziness is the father of invention". Norm Return to table of contents

I chill to a low temperature because I want a good break and I want to let the break settle for several hours (overnight). The low temperature improves the cold break *and* reduces the probability of contamination. I don't have any means of refrigeration other thatn the chiller which will drop the temperature so effectively. I like to ferment at 60-65 degrees anyway. I've had mixed results with the beers I've fermented warmer than that. _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Mike McNally mcnally at wsl.dec.com Digital Equipment Corporation Western Software Lab Return to table of contents

In his talk on wort chillers at the Conference, Jeff Frane said the most enlightening (to me) fact of the whole conference: that cold break begins at 65F. Wow! Since then, I've been chilling down to 60F with my immersion chiller, waiting a half hour or an hour for the cold break to form and then running very warm water through the chiller to bring the wort back to pitching temperature. Note that this is also possible with a counterflow chiller and the coil-in-bucket chiller, but you must siphon twice. I need to use only very warm water because although my chiller outlet hose is PE and can withstand a lot of heat, the inlet hose is only PVC and melted once when I ran 140F water through it (it buldged out and then burst like a bad radiator hose).

By boosting the heat of your mash to 170-175F and holding for about five minutes, you effectively end starch conversion. After mash-out you can begin the recirculation process and then move on to sparging. Some eschew the mash-out, just as others prefer not to use a protein rest. If you're happy with your results, that's cool, but I recommend both steps. But the fact of the matter is, there should be no confusing mash-out and sparging -- they are definitely NOT the same thing. - ------ Steve Hamburg Internet: stevie at spss.com SPSS Inc.

Date: Tue, 4 Aug 92 18:06 GMT From: Phillip Seitz <0004531571 at mcimail.com> Subject: Malto-dextrine I am certainly not the final authority on brewing, and most of my knowledge is still based on reading rather than experience. This disclaimer aside: I did an experiment at home to see what the results of using malto- dextrine and lactose would be in terms of flavor, mouthfeel, and added gravity. Two one-gallon batches of water were prepared, one with a cup of MD, the other with a cup of lactose. Both were boiled and cooled. Both added substantially to mouthfeel. The malto-dextrine added nothing at all in terms of flavor, while the lactose added a very slightly sweet taste--really rather mild, but noticeable. Each raised the gravity of one gallon of water from 1.000 to 1.014. If I'm not mistaken, this rise in gravity consists entirely of unfermentabe sugars, and would therefore remain after fermentation is complete. As for use of these, I'm still experimenting. My philosophy at the moment is that both serve as extract-brew equivilents of dextrine malt. Armed with the gravity results above, I therefore use the malto-dextrine to supply the same number of gravity points as the desired amount of dextrine malt (1/2 pound of dextrine malt is pretty common, with a whole pound for fuller, more substantial beers). I don't have my notes here, but this comes out to about 1/2 or 1 cup of the above. I've seen recipes here on HBD that use as much as 14 ounces of lactose. If I'm doing something wrong here I'll be glad to be corrected-- I hate wasting beer! Return to table of contents

Date: 04 Aug 92 14:36:25 EST From: Ruth Mazo Karras <RKARRAS at PENNSAS.UPENN.EDU> Subject: lauter/mash tuns Crhis Shelton asks why use a strainer/steamer if a grain bag is also being used. Although I have not experimented without both the steamer and bag, the theory is this: the steamer raises the level of the grain above the drain (which is set into the side of the tun) so that as the grain is sparged the sparge water drips from the grain bed with a horizontil cross-section equivalient to the daiameter of the tun and then collects beneath the steamer and flows to the drain; the grain bag provides a finer filter for the bottom of the grain and generally keeps the grain bed together to make clean up easier. Not using the steamer may lead to plugging the drain and not using the grain bag might lead to grain falling through the steamer and flowing through the drain. A collander filter in the bottom of the tun probably does much the same thing as I have described, but I would guess clean up is tougher than with a grain bag. With the bag, I just lift out the grain, set in in the sink to finish dripping and carry it out to the garden. Since I am keeping the sparge water to within a half inch of the top of the grain bed to keep it afloat, I have not had a problem with sparge water running down the side of the tun and not sparging the grain. At least I think I do not have that problem. Another reader aske whether a grain bag really makes it easier to clean up, since the bag has to be emptied and washed and what not. Putting the grain bag in the tun takes about 15 seconds and removing the grain in the bag less time. Rinsing out the tun after removal of the bag is quicker than it would be if the bag were not used, I think, since there is less grain to rinse out and cleaning the bag consists of dumping the grain in the garden, turning the bag inside out and rinsing it for a minute or so in the sink. I have not been sanitizing the bag as it is nylon and the wort does get boiled. I do not think this is a big deal, and makes it easier to move the grain out--but the $7 for the bag might not be worth it to everyone.

I seems to me that combining the two techniques would easily >allow for cooling to a reasonable lager pitching temp. > So, what is an appropriate pitching temperature for Lagers? I have seen brewers go through extreme lengths to make sure both the pitching yeast and the wort are at fermentation temps (e.g. 48f) and I have seen others (yours truely) just chuck the yeast (room temp or refer temp) into the wort that comes out of the chiller (~65-75f). Both work fine. In fact it would appear that my RDWHAHB method works better since the yeast goes through the lag time faster due to the higher temperatures. Of course, by the time the yeast gets really going, my beers are at 48f (~6-24hr depending upon the quality of the starter). >From club tasting results I can't see any reason to worry about pitching lager yeasts at fermentation temperatures.

There are two reasons for mash-out that I can think of: 1) stopping conversion (in some cases, as when making a highly dextrinous wort, you may want to stop conversion before all the dextrins are converted to fermentables) and 2) raising the temperature of the *grain* to 170F so the sugar flows more easily away from the husk material (this way, you don't use sparge water to warm the grain and the grist stays at 170F (or as close to it as your insulation allows) for the entire duration of the sparge). A 2-hour sparge does sound excessive, but too fast a sparge will also lower your extraction efficiency. Al. Return to table of contents

The grain bag gets set into it when dry, and tied down around the cooler top. Then I add water and grain, alternating and stirring. The grain bag really is no problem. In fact I think it makes cleaning a little easier. When I'm done I can carry the cooler out to the compost pile, lift the grain bag out, and invert it to dump out the grain. Then I simply rinse it and let it dry. I certainly wouldn't say it makes things any harder, and perhaps makes cleanup a little easier. While I know plenty of folks who use a collander or vegetable steamer false bottom and no grain bag approach with good results, using the grain bag what and slotted pipe combination as I have also works fine. > Am I missing something?
