Therefore interrupting the circuit when the switch is off and >completing it when the switch is on? Yes this is the correct way. The terminal screws on the switch should both be brass. If you look at an outlet, one will be brass and the other nickel. The brass is for black wire and the nickel is for the white wire. An easy to remember this is, dark screw=dark wire and light screw=light wire. I believe this a industry standard. In my line of work, I've had the opportunity to wire various equipment. Sometimes other colors are used but usually dark colors are hot and light colors are neutral. I've never seen any color but green for earth ground. If the outlet to which you are going to connect the pump it not GFI get a GFI outlet and install it. This will help protect you from electrical shock. The breaker in the electrical panel protects your wiring and a GFI outlet protects you. John Schnupp, N3CNL Colchester, VT 95 XLH 1200 Return to table of contents
Date: Wed, 19 Aug 1998 01:39:37 -0400 From: "Timothy Green" <TimGreen at ix.netcom.com> Subject: RE: Imperial Stout Victor Farren Writes: >Can I add fresh starter from the dregs of the 2ndary and use the newly fermenting yeast when bottling or will the high >alcohol in the IS have made them too loopy to do a good job? Will they be prone to giving off flavors? I know that it is not >a good idea to ferment another batch with yeast that has fermented a BIG beer b/c the alcohol content mutates them, but I >don't know if that would hold for bottling where there is a small addition of fermentable sugar and thus not a lot of new >fermenting going on. I don't see that you should have any trouble using a fresh starter made from the secondary dregs. I have done the same a number of times. About the idea of not reusing the yeast from a BIG beer, I am still searching for where this information has been coming from. As a mead maker before I began to brew beer, I have often pitched a fresh must onto the dregs of a previous batch with no ill effects what so ever. The SG's of my meads are invariably 1.090 or greater and normally around 1.110. I have seen no change in the flavor characteristics produced by the yeast being reused. Now before someone jumps in saying wine yeasts are different from beer yeasts, I have done the same with ciders and I use ale yeasts almost exclusively in my ciders. The only difference I have seen in reusing yeasts is that sometimes they ferment out to their limits much faster than a new starter will. I have come to believe that this is because there is a much larger amount of active yeast in the yeast cake than in a starter. I hope your stout turns out fantastic! Tim Green Mead is great... Beer is good... (But beer is much faster) Return to table of contents

Both of these go to Australians reading this as they are about getting equiptment in Australia , but Hi to all those international readeres any how. I was interested to find out if anyone knew where to get those 19l (5gallon) soft drink kegs they used to use from post mix drinks. A friend tells me they dont use them any more and I would love to find a few to experiment with kegging. ___________________________________________________ On the yeast issue, I was wondering if anyone knew of a lager tyle beer with a live yeast sediment. Having just aquired more fermenters I am keen to try adn make a style of beer with a lower fermentation temp while its still cool at home and I can do it with out having fermenters in the fridge. Any help appreciated Cheers Darren Robey Return to table of contents

My apologies to all. Truth is, I shot from the hip, wrote poorly, and posted out of sheer boredom whilst awaiting a long overdue (insert fanfare here) ARRIVAL OF A NEW BREWER (wwwwrrraaaahhhhh!!!!! ...the crowd goes wild! Let's see if we can't get a "Wave" going...) Sara Ann, born after a long and difficult labor, is already showing signs of exquisite taste and an appreciation of fine brewing; having insisted on lagering far longer than Mom wanted. Funny how a quiet, prune-like creature can captivate your heart after only a few minutes... The dreams are already there; teaching her to count (1.010, 1.020, 1.030), how to tell time (Sara, when the big hand reaches the nine, open the sparge valve like a good girl, okay?) and all the other important things that Dad knows about life; how to properly tip a gondolier, which button shuts down a helicopter, why you should never freeze basil... Please join me in raising a glass in praise of a fine team of gentle and caring physicians, a brave Mom, and a beautiful new prune -er, brewer. May we prove to be kind and worthy parents. -Bill Anderson Prague, Czech Republic anderson at ini.cz P.S. Thanks for allowing such sentimental drivel into an otherwise excellent resource.

Date: Wed, 19 Aug 1998 08:45:23 EDT From: Jebbly at aol.com Subject: Calculating increases in batch size Phil, Thanks for your response to my questions on increasing my batch sizes. All of your information was very helpful. I am still in the dark on how to calculate the amount of grains (ie increase them). I'm reposting this on the hbd, but would also like to pick your brain a bit more. I have also had time to think of more questions. Basically, I have worked hard to develop some very fine (in my mind) 5 gal all grain recipes and now want to brew larger batches and sock them away for the winter. I've tried brewing back to back batches in the same day which is far too time consuming. HBD: I posted this question a few days ago, but maybe I wasn't very clear. I have been mashing 5 gal batches and now want to increase the size of some of my recipes to 10 and 15 gal sizes. Can anyone give me some >>detailed<< guidance on calculating the increase in grains, hop scheduling, yeast prep and sparge time: 1. Is a one pint starter of yeast enough for a larger batch, or should I start a quart or more? 2. How do I figure the proportional increase in grains? 3. Hop bitterness doesn't seem that tough to figure out, but I could use some advice as well as for hop aroma. Thanks again. Dave Grommons Return to table of contents
Date: Wed, 19 Aug 1998 09:44:11 -0400 (EDT) From: Aaron Banerjee <aaron at mirror.his.com> Subject: Measuring alcohol content with salt Recently I read in a very old chemistry handbook (which discusses brewing beer, making wine, and distilling spirits) that one way to determine the alcohol content is by dissolving common table salt before and after. As the wort ferments, less salt will disolve. For mixtures which are purely alcohol and water, you only need to do this after distillation, because the amount of salt water will disolve is known. Does anyone know if this works? Has anyone tried it? I'll supply more details if anyone wants them. - Aaron Banerjee p.s. I know there are better ways of determining alcohol content, but this sounded kind of neat. Return to table of contents

It all makes sense now. Bottling Imperial Stout-- Thanx to those who sent me emails. I think I will wash the dregs of the 2ndary and 'freshen' them up w/ a some 'normal' gravity starter. FYI I took a gravity reading last night and it was at 1.020, down from 1.090! Woohoo! I guess that 2 liter starter really did the job! For those who are interested, I used Wyeast Thames Valley for this one. Good to know it won't konk early b/c of alcohol content. Return to table of contents
Date: Wed, 19 Aug 1998 07:55:51 -0700 From: Charley <caburns at egusd.k12.ca.us> Subject: re:Yeast Data Regarding Mort's excellent post (hbd#2802) on volume of yeast slurry (in fl oz) to pitch to reach optimal rate. It was me. Asking for how much slurry should I pitch, hopefully in liquid oz measurements. I can see that with the jillions of variables involved that's not a very realistic question, unless we have the equipment needed to take a few measurements. Thus, if I had a centrifuge I could use the data you provide to get much closer to an answer. But I don't. I do follow some similiar procedures when I recover and wash yeast, storing under boiled distilled water. What I don't know is how much liquid is lost during centrifuge (so I can adjust the calculations). What I see from your excellent post is from .77 oz up to 3.26 oz. Now the post says its fl oz, but it appears to be very close to my standard conversion of 28 gm to 1 oz. Is this because almost all of the water is gone? I guess I'm curious as to how the conversion from weight to volume was accomplished. (probably a stupid question so my flame shields are up now). Next question is for what volume of wort is the volume of yeast for (approx) comm. pitch rate given? ie for yeast cake A, .77 fl oz of yeast into how many gallons of wort? Last question is, if I assume that my slurry is at the lowest end of your discovery regarding viability and density and accumulate enough slurry to reach the commercial rate, what happens (to the beer) if my slurry is _actually_ at the high end? Based on the table presented (assuming this is the entire universe of possibilities and my slurry falls within them) I could potentially be pitching 4 times as much yeast as is needed (optimal?). What impact will this have on the beer? Is this serious over pitching or only a "little" overpitching? What is the expected impact of pitching say 10 or 20 times the "nominal/optimal" rate? And what about Mary Lou.... Two bazillion and 1, two bazillion and two, two bazillion and ..... Charley (still counting) in N. Cal Return to table of contents
Date: Wed, 19 Aug 1998 11:15:22 -0400 From: "Zierdt, Cpt John" <Zierdt at jbc.js.mil> Subject: Kegging with Nitrogen I have been lurking since I started brewing in April and this forum has helped me to make some great homebrew. Now I need some help with a topic that I have not seen covered here or in the archives. I am getting ready to buy equipment to start kegging my beer. I would like to serve all of my beers with nitrogen ala Guinness. I have tried 10-12 different beers served with N2 and I love the creamy mouthfeel on everythig from IPA to stout. My question: Is it possible to do with a cobra faucet or do I need to get the actual Guinness style tap with the restrictor plate? I do plan on buying the taps at a later date but I would like to start out with just the picnic tap. I believe I can get the Mixed gas and the N2 regulator fairly easily and would prime the kegs with sugar instead of force carbonating. Has anyone out there ever done this or seen it done? Any hints or suggestions would be greatly appreciated. Thanks, John Zierdt Virginia Beach Return to table of contents
Date: Wed, 19 Aug 1998 11:21:44 -0400 From: Mark_Ohrstrom/Humphrey_Products at humphreypc.com Subject: Pump Wiring Disclaimer: I am not a licensed electrician, nor have I played one on television ... >Now my question. Can I simply wire the ground to the ground, the White to >the White, and then Wire the Black wires one to each of the connections on >the switch? Therefore interrupting the circuit when the switch is off and >completing it when the switch is on? Yep, you've got it right, but maybe not for the right reason. The green IS ground, the white is "neutral" (also connected to ground -- go figure), and the black is "hot". Positive and Negative changes wires in an *alternating* current circuit. If you look at the screws on your switch, one is green (for the ground wire), and the others either silver-colored or brass. The white goes to the silver, and the black to the brass (this way, you are switching the "hot" wire on or off. If the neutral were the one being switched, a circuit could still be completed (through YOU -- ow-eee!) from the hot to ground, or to another neutral.) Loop the wire clockwise around the screw so that it tightens as you tighten the screw. I would recommend getting a Reader's Digest Do-It-Yourself manual from the library (~$20 to buy), or a copy of "Practical Wiring" for about $5 (it used to have a cool hole drilled through it so you could hang it on a nail) - -- especially if you are a homeowner. Also, watch the Radio Shaft ads for a cheap VOM (volt-ohm-milliamp) meter. They are really handy for everything from checking for hot circuits to testing batteries. Also, get one of those $3 plug-in devices that checks if the outlet is wired correctly! If it isn't (and too often they aren't) you can still get zapped -- brewing water and electricity DON'T mix!

This brought to mind the "Free to a good home: slightly used conspiracy theory" e-mail I got from a person who runs a couple of listservs. The AHA/AOB is an organization with money and they contracted with a provider to handle this stuff. Then Pat and Karl with their own time and effort resurrected things (check out the history at hbd.org). If the AHA/AOB really cared they would have hired somebody to fix things but they did not. The AHA/AOB deserved to get flailed. Karl and Pat made it work. Karl provided a judge list when the judgenet went down. Look at the machine this list runs on now. Can you say frankenstein? But it works. Because these guys care! So now the AHA has techtalk for it's members and it has largley failed. Killer factors have been reported to contain a glycoprotein that exerts its lethal effect by changing the integrity of the plasma membrane of sensitive strains. Killer strains of Saccharomyces contain a cytoplasmic doulbe stranded RNA that codes for an extracellular toxin as well as for an immunity factor that gives the ability for the infected cell to protect itself from the toxin.

Date: 19 Aug 1998 12:19:57 -0400 From: EFOUCH at steelcase.com Subject: Fresh hops HBD- I have a few questions regarding Joe Kish's admonitions to use fresh hops off the bine: From: "J. Kish" <jjkish at worldnet.att.net> Subject: Hops-Off-The-Vine To: Ian Smith You asked about using hops direct off the vine and into your beer. Do it! I did it last year, and it is beautiful! Outstanding flavor, and there is an improvement in the foamy head. I can hardly wait until my hop flowers are ready---any day now. I have seen posted here in the HBD about a grassy odor/flavor in finished beer as a result of using home grown hops. Is this because the hops may have been picked too soon? I originally thought it may be because they weren't dried properly. Here we have a data point indicating inadequate drying is not the culprit? Also- I have read somewhere that hops need to be a little oxidized. Sure, we want to store them in oxygen barrier containers to avoid gross oxidation, but I seem to have been led to believe (don't remember where) that a small amount of initial oxidation is desirable for optimal hop flavor. I don't think I'm confusing this with oxidized hops for lambics. Does anybody have references on this?

Date: Wed, 19 Aug 1998 12:52:20 -0700 From: George_De_Piro at berlex.com Subject: Yeast and oxygen Hi all, I read an interesting abstract in the Journal of the Institute of Brewing (July-Aug. 1998). It is an experiment in which yeast were grown under 3 different conditions: 1. With continuous aeration 2. Aeration for one hour 3. Anaerobically Under aerobic conditions the yeast's levels of fatty acids increased while under anaerobic conditions the levels of storage sugars increased (no surprise). In test fermentations with the yeast thus grown, the aerobically cultivated yeast grew to larger numbers, had higher viability, and higher levels of both fatty acids and storage sugars than the yeast cultivated anearobically (again, not too surprising, but important). There were no significant differences in fermentation performance between the yeast cultivated with continuous aeration or those with one hour of aeration (that seems interesting to me). Since I only have access to the abstract, I am missing certain experimental details that would be interesting to know. One thing that I'd like to know is if the yeast were aerated at all when pitched into wort for the fermentation tests (my guess would be that they were not). Also, how big was the test fermentation, and what were the pitching rates? How many times were the starters fed, and was the starter that was only given O2 for one hour given O2 at each feeding? Was pure O2 used, or air? Perhaps some others out there (with a good library) can enlighten us further (Jim? Mort? I'm always bugging you guys). This paper would have practical applications both at home and in larger breweries. If continuous aeration/oxygenation isn't needed, why bother with it? The paper is: Effects of aeration during the cultivation of pitching yeast on its characteristics during the subsequent fermentation of wort H Maemura, S Morimura, K Kida JIB Vol. 104 No. 4, pp. 207-211 Have fun!

Date: Wed, 19 Aug 1998 12:24:30 -0400 From: oberlbk at NU.COM Subject: Nitrogen and Refrigerators This is a two part question. The first has to do with converting a fridge or a freezer to a beer dispenser. In order to have more room in the freezer, I would like to have the CO2 tank outside. Is it a problem if you use a shank to go through the wall of the freezer?? If you do not use a shank, how do you get through the wall? You could just stick a hose through and foam it in place, but this seems like any tugging on the line would cause problems. My second issue has to do with using mixed gas on homebrew. I found a place with some quality "Guiness gas" and I would like to use it to create that magical head on my brew. Do you simply just force carbonate with the mixed gas and then dispense with it too? I have also heard that you lightly carbonate with CO2 and finish the job/dispense with the mixed gas. Which is correct? Finally, when it comes to the faucet to go on the front of the freezer, it appears that there are 2 types of "stout" faucets. One is called standard, and the other is a restrictor faucet. What is the difference and which one will duplicate that Guiness pour? I would guess the restrictor nozzle, but who wants to spend the money on a guess. Ooops, one more question. Do I need a special regulator to dispense mixed gas, or is my CO2 regulator good enough? Thanks in advance. Private emails work for me.

I have been following the recent talk of parti-gyle brewing and have a question of Dave Riedel (posted in #2801) and the rest of the group in general. Dave responded that he has done a parti-gyle double brew session based on 12# of grain, the first runnings yield was 3 gal. at 1.099 and the second runnings were 6 gal. at 1.048, when I do the math this seems to be a bit high in extraction. (3 X 99) + (6 X 48) --------------------- = 48 points per pound of grain !!! 12 Dave, what type of mash schedule were you using and what do you use for a mash tun? What were the final gravities of these brews, I've got to think you had some non-fermentables in there as the the extraction rate comes out on the high side. To the rest of the collective, what has you experience been with parti-gyle as far as amount of grain used and the yields for the first and second runnings.

I figure that there aren't a whole lot of alive bacteria in an oven, anyway. >Cram as many as possible into my oven (luckily my oven holds exactly >enough for a 5 gallon batch). I stand them up I remove the top rack in the oven, then rest mine on the side and stack them all on top of each other. In my apartment sized stove, I can fit all 54 bottles. >Set the time bake to kick on at 3:00 am for 1 hour at 350 deg. >Take them out of the oven the next day and store them for whenever I need >them. > I preheat the oven to 200 degrees before placing them inside. Then I leave them in NO longer than 15 minutes at 200 degrees. I believe 180 degrees is the point at which bacteria dies. 200 is plenty safe. I have heard that higher temperatures and longer times in the oven my weaken the structure of the glass. Once done, I let them cool in the oven for awhile, then remove and put into my long-neck case boxes and cover the tops of the bottles with celophane wrap to keep air out until bottling. (Don't touch the openings of the bottles when you remove them. I use a clean dishtowel...it also acts as a hotpad). I've stored them this way for up to a week, but it's probably best to bottle sooner rather than later. I've never used any other sanitation method, and have done almost 30 batches this way. Never had a bad beer from a bacteria problem caused by a dirty bottle. I have experienced this in other homebrew...it's pretty obvious! As always, good sanitation in every other step is a must. I always rinse the bottle right after pouring into a glass and air dry upside down. This way, I don't allow the sediment in the bottom to cake on or start to mold, and the bottles are mostly clean already. On bottling day, I wash my bottles in regular dishwashing detergent and use a bottle brush to get them clean. Then, I rinse well and let air dry before putting them into the oven to "bake." The only down side is that if you do the baking on the same day as the bottling, you will have to wait 2 or 3 hours until the bottles cool. I've never done it, but I don't think pouring 70 degree beer into a 150 degree bottle would be good for it. Rod Wellman Sioux City, Ia. Return to table of contents

Now >the post says its fl oz, but it appears to be very close to my standard >conversion of 28 gm to 1 oz. Is this because almost all of the water is >gone? I guess I'm curious as to how the conversion from weight to volume >was accomplished. (probably a stupid question so my flame shields are up >now). Not such a stupid question. 1 gram of yeast slurry occupies a volume of almost exactly 1 ml (I have found this to be true for both centrifuged and gravity-settled yeast, and I guess this shows that yeast is mostly water). So, for our purposes a gram is a ml, and to convert ml to fluid ounces, just divide by 29.5727. For example: 22.6 g yeast = 22.6/29.5727 fl.oz. yeast = 0.77 fl.oz. yeast Note that I do not claim this is *exactly* accurate, but it should put you in the ballpark. >Next question is for what volume of wort is the volume of yeast for >(approx) comm. pitch rate given? ie for yeast cake A, .77 fl oz of yeast >into how many gallons of wort? Sorry. It should have said in 5 gal. of wort. What you should really do is just take the figures for cells/g of yeast cake and figure out how much you would need to achieve a rate of 1 million cells/ml per degree Plato of your wort. Also note that in the table for centrifuged yeast, the 5th row, Total Cells, is a complete mistake (the 3rd row accurately reflects the figures for total cells). I don't know how it got in there but it was not used for any other calculations and should be ignored. >Last question is, if I assume that my slurry is at the lowest end of >your discovery regarding viability and density and accumulate enough >slurry to reach the commercial rate, what happens (to the beer) if my >slurry is _actually_ at the high end? Based on the table presented >(assuming this is the entire universe of possibilities and my slurry >falls within them) I could potentially be pitching 4 times as much yeast >as is needed (optimal?). What impact will this have on the beer? Is this >serious over pitching or only a "little" overpitching? Probably would not be a big deal. Assuming the data I showed represents the whole range to be expected in yeast density (and I'm sure it doesn't) then you could expect to be pitching between 10 and 40 million cells/ml. I would feel much more comfortable in this range than in the 0.1 to 0.2 million cells/ml that many homebrewers actually use. >What is the expected impact of pitching say 10 or 20 times the >"nominal/optimal" rate? And what about Mary Lou.... The impact that is generally expected is that you would have very little yeast growth, a slightly slower fermentation than normal, and perhaps a different flavor profile. However, there is conflicting evidence regarding these expectations, and this is one of the things I'm looking into at the moment. I don't have any answers yet. Hope this helped.

Date: Thu, 20 Aug 1998 00:03:41 +0100 From: "Dr. Pivo" <irv at wireworks.se> Subject: cooling/ HSA I've got some good news, some bad news, and some very bad news. (I am presenting this in the perspective of the HBD tradition of vociferously chanting the cause, of industrial brewing literature). I have been experimenting with "chilled vs. nonchilled" and "non chilled normal treated vs. non chilled intentionally created HSA" batches. I have triangle tested these (thanks for that tip Mr. Louis K. Bonham). The good news is that there is "almost" a statistical significant difference between chilled and non-chilled beers ( sorry about that J. Schmidling). This points to me an obvious need for repetition and larger sample size. (What in the name of Pee Wee Herman's bicycle are all you homebrewer's out there doin'?) The bad news, is that of the individuals that could distinguish a difference, there was by no means any clear cut preference between the two. The very bad news, was that the intentionally created "HSA" (does that stand for Heirarchically Submitted Answers?) was so far from being "significant" that it does not bear repeating in that test format. When I get my backside removed from it's comfortable position placed on my left thumb, I'll try and write up some sort of "material and methods" thing, plus a critique of possible introduced variables, confounders, and the like that have occurred in this 'spearment-- That really is the meat of doing any of this stuff (look for your errors, and you'll likely find what is valid). As per usual, I'll not post here, but wave a flag when done, and point to it. I'll shortly mention that the "intentional HSA" was created by dropping a load, like Slim Pickens riding the bomb in "Doctor Strangelove", right out of the boiler, and letting it splash land merrily about a meter below. This will at least give the vanguards of dogma a chance to sharpen their argumentative pencils, and anyone interested in finding out what's really going on, to arrange their own experiments. It really would be nice with larger numbers, and more independent tests. Dr. Pivo Return to table of contents

Or just more authentic >First Mash Junipering (FMJ)? Please, do not use hops when brewing sahti. This is because if you boil hops you get bitterness in your sahti. This is an absolute no- no. Sahti should taste sweet - you don't want any bitterness, because it would balance (reduce) the observed sweetness. Many masters claim to use hops but not like they are used in brewing beer: first you boil the hops in plain water, discard the water and use the non-bitter hops in sahti. In addition, the amount of hops is very small, almost negligible, say a handful in several hundred liters of sahti. This amount is really nothing. Juniper is usually used as a lautering aid: hot, boiling mash is poured onto a bed of juniper twigs. Personally, I prefer late addition of juniper to the traditional lautering with juniper branches: you need less juniper and the effect is more intense. This method is more of less "dry-junipering": after the fermentation is over, cut and crush juniper twigs into your sahti, start trials with about 0.5 g of juniper per liter, let soak for a week, filter.

This seems rather odd since nearly all yeast have a latent capability for decarboxylation. I wouldn't necessarily expect 4VG producers to share many other properties in common. Got a source ? Also he writes ... > I feel that beer reviews here on the digest are of very limited > usefulness. Reviews of brewpubs are pointless to anybody outside of > the geographic region of the reviewer (i.e., almost everybody). I think that www.pubcrawler.com is a better, since this maintains the information collated and available for ready access. As for pub reviews (on pubcrawler) not being of value - I guess that depends on how often you travel. It was a godsend when I used to travel 15-20 weeks a year. >Reviews of beers are highly subjective, and many micro and import >beers do not travel and store well. All experiences in life are entirely subjective, only a shared experience gives the illusion of objectivity. Individual tastes differ. Even so, I think that over time and large sample spaces there is broad agreement about what generally constitutes a good beer or a bad beer I would much rather select from a list of 10 "might be goods" than from a sea of "don't knows" when I can only have one or two choices. > As a beer geek (and BJCP type) I think it is important to try as many > different commercial beers as you (and your liver) can afford. Gee, about 2 years ago I was given a Peach Lager (?) from Florida that tasted only of diacetyl and grass with a bit of "bandaid" in the background. If you really think it's important to try as many different commercial beers as possible you'll certainly want to sample this one. (note for the humor impaired - this is sarcasm). Not to disagree with the intent tho' - George is quite right that continuing to sample a wide range of beers, including imperfect examples, is a very important learning experience. I am not in advocating giving away judgment and choice to either "pubcrawler" or the written reviews of experts, yet I find such reviews useful. Since we don't have time to sample all beers it is necessary to make choices among the possibilities. I am only advocating that it is much better to make that choice based on limited information rather than choosing at random based on no information. Don't you agree ?
