I have seen lower IBU, esters, higher alcohol (who knows how much FAN was used) with high pitching rates, BUT lower fusels with ALE yeast when I pitch big. I thought a higher pitching rate should give the yeast less chance for alternate pathways which produce the fusels in the first place.

Date: Tue, 6 Feb 1996 21:43:37 +0500 From: "Pat Babcock" <pbabcock at oeonline.com> Subject: Diacetyl: The Movie Greetings, Beerlings! Take me to your lager... The Drinkur Purdee Pico Brewery Demographics Department (me) called in the Statistician Department (again: me) and the Computer Information Services Department (guess who?) and the Gee What Did This Person Really Mean Psychic Department and slaved late into the night to enlighten you, totally free of charge, with the following conclusions. OK. So here they are: THE CONCLUSIONS: o Pronunciation of diacetyl is not regional. It is also not logical. o There are as many ways to pronounce diacetyl as there were respondents to the survey. o Some people get really uppity when answering surveys. o Some people have a lot of fun while answering surveys. o Some people will never ask a survey-type question again. OK. One person. Me. :-) o The people who write dictionaries must be required to not give the same pronunciation as a competing dictionary does. Must be a copyright or monopoly thing> MAybe they don't want to stifle creativity or something. o According to the results of this survey, if the sampling is valid, I have the distinction of being the Only Guy On The Planet Who Says Die - uh - seht - ul. I'm having a tee-shirt made as I write this. o You'd have to get up VERY early in the morning to beat Spencer! At least the morning of the 30th. Yikes! o Someone called 'The Lawyers' said that Jim Koch [TM] has trademarked diacetyl, and that by asking the question I was in violation. Mail sent to confirm bounced off their lawyer-bot. THE ANALYSIS... By far, the most popular pronunciation is die-ASS-it-il; seconded by Die-UH-seet-il. There were many other pronuciations offered, which I have "grouped" according to similarity (that was part of the Gee What Did This Person Really Mean Psychic Department's job). Only the group total is shown (in percent). The most representative pronunciation 'defines' the group. 47 respondants providing 57 responses Die-ASS-it-il 32% die-ASS-uh-til 12% die uh SEET ul 12% die-uh-cetyl 23% die-ass-a-teal 11% die-ass-see-til 11% Dictionary responces: di-a-suh'-tuhl DIE-uh-seet-il die-UH-seet-il die UH set-eel di'e-set'l di-as'i-tl die'-uh-seet'-l di' <schwa> set" <schwa>l (Is that a LONG e in set, Scott? Mebbe I'm _NOT_ alone...) di' as" i t<schwa>l die-uh-SEET-ul die-ASS-it-il Die-ASS-eet-il Well, there ya have it. My apologies for the bandwidth - I'll never, never, never ask this type of question again. And, I'll pronounce diacetyl like: that-but'-<schwa>r-<long e>-fl<long a>'v<schwa>r See ya!

Date: Tue, 6 Feb 1996 22:31:07 -0500 From: denisb at CAM.ORG (Denis Barsalo) Subject: Garden Brewery Plans Hi guys and gals, I'm planning on building a new garden shed this summer and I just got the O.K. from my SO to build a brewery as well if I want. I'm trying to determine the minimum space I need for brewing 5 gallon batches and leave myself a little extra room for storage and eventually larger batches if it ever gets to that point. I would buy a propane burner (maybe eventually two), I would install a sink with a weeping tile type of drain and run a garden hose from the house to the shed for washing and for the CF chiller. I always buy a couple of plastic carboys full of RO water for each batch I brew. The homebrew store where I buy my supplies sells them for $1 each when you buy the supplies for a batch (kit or grain). I've decide that I shouldn't go any smaller than 6' x 9'. (Check out first attempt at asci art below.) The door is on the left of the 6' wall with the garage on the left just behind the opened door. What I'm thinking of doing is having a counter with a sink run up all along the right 9' side. On the other end along the 6' wall I would put the burner with a vent. I'm not sure if I'm going to build a tiered system or use pumps. At the moment, I use a zapap lauter tun and I mash in my brew kettle. Eventually, I could see myself buying another kettle for mashing and attaching a homemade easymasher type of thingy to it. I've also built a bruheat type of thing for heating 20 liters of sparge water, so all I really need room for is one burner. This is mostly a three season set up, with the odd batch on winter days that are not bloody freezing! What do you think? Do you have any great ideas? How powerful of a vent do I need to evacuate the CO2? Denis Barsalo P.S. Is there any sort of FAQ or paper on building a brewery? | Garden Shed | | | |________________________________| | | sink | counter | |--------------------------------| | b | | | u | | | r | \ | n | \ | e | \ |__r_|__________________________ \ | | | Garage | | | Return to table of contents

The SO and I are planning a trip to Fort Myers, Florida in the next few weeks. I hope to take her to a nice restaraunt or two, and _by accident_ discover that they serve great beers there, too! So, how 'bout it--anyone know of any nice restaraunts down there that also have a nice selection of beers? Private e-mail preferred TIA Kevin A.

Date: Wed, 7 Feb 1996 00:16:00 -0500 From: bob at carol.net (Robert Rogers) Subject: keging i use a corny keg and i love it. i have used both the priming and gas injection systems one time each. for the priming method, i used 5oz of sugar (just like for bottling). i gave it a little gas to seal the o-ring and let it sit for a few days, and it got up to 20psi and i started drinking it. for the injection method, hook the gas to the _out_ side of the keg. that way the gas will bubble up through the beer. pump it up to 30psi and let it sit a day or two and it will be carbonated. remember: the colder the liquid, the more CO2 it will hold in suspension. i think i have just come up with the ultimate entry level homebrew conry system. seem like it would cost around $20 or $30 for a 2.5 gal system. here's my idea: those of you with friends who use drugs will know what a whippet machine is. basically, it is a piece of machined brass with an o-ring and a spike that screws together to discharge small NO2 cartridges. as best i recall, NO2 and CO2 cartridges have the same form factor (the CO2 cartridges that are used in air guns). OK take the whippet machine and solder it to a small piece of copper tube. crim the tube to vinal tube. attach the vinal tube to one of those ball connectors. when you put the primed beer into the keg, you could hook up the hose and discharge a CO2 cartridge. you should be able to drink a considerable ammt. of beer before another CO2 cartridge would be required. any thoughts on how much beer could be dispensed with one of those cartridges? bob rogers bob at carol.net "Why, Fritz, alcohol is a gift from God..." --young Fritz Maytag's Mom Return to table of contents

[snip] > I have some beer which was brewed at least 10 years ago by my > ex-wife's grandfather (I don't remember what it is. It is amber in [snip] i read a technical report on bottling technology a few years back. they determined that the shelf life of beer in bottles in the best of circumstances was about 6 months. that's from a high tech bottling line. they reported a micro brewery was doing good if it could bottle beer that would keep for 2 months. given those rates, it seems like us home brewers can probably count on our beer going bad just before it has aged properly :) :) that said, i would say open it and try it. if it tastes bad don't drink it. let us know how it turns out. bob rogers bob at carol.net "Why, Fritz, alcohol is a gift from God..." --young Fritz Maytag's Mom Return to table of contents

Is there anyone who has done such a thing?=^) I'd love to hear from the tropicaal meadsters about open ferments.

Date: Wed, 7 Feb 1996 06:08:25 -0600 (CST) From: d2dtinfo at inlink.com (CCGDTWO) Subject: Skimming Friends During the open ferment discussion I decided I would give it a try. I've made three beers so far using open ferment. I have a BIG (1074) porter or old ale fermenting like crazy now. I've skimmed it 5 times in the last two days it makes such huge krausen. I sorta lost track of how much or many times or days to skim. Is there a point where you quit and let the krausen fall back into the beer. I don't want to lose all the bitterness as the green beer was quite sweet going in. I tasted the skimmed krausen and it was rather foul tasting, really bitter. Am I losing bitterness by skimming?

I have had similar results with grain bills of various sizes. The water additions for 10 pounds of grain and the extrapolated ones for 11 pounds of grain gave me the very same results. (140F instead of 150F) The last two batches I've made I just "rested" the mash at 140F (60C), stepping up from 122F (50C) and eventually going to 158F (70C). This basically recreates George Fix's 50-60-70 schedule for well-modified grain doesn't it? I think your suggestion to bring the mash up to 132F before adding the water is a good alternative to using more water and ending up with a thinner mash. If I did use more water, would I need less sparge water? Under which conditions would I want to use a 40C-60C-70C mash schedule? Is this for a specific style of beer, or for less-modified grain bills? How would you recommend I step the mash up from 40C to 60C? More water? Denis Barsalo Return to table of contents

Can a pail that held vinegar be trusted? > No hard data on this, just the usual morass of half-remembered factoids: Vinegar certainly *used* to be produced by bacterial action on alcohol. When I was a boy, mumblety-odd years ago, I recall instructions on how to culture the slime at the bottom of a vinegar bottle ("mother of vinegar") to produce one's own vinegar at home. (This was a really dumb idea for a kid's experiment, BTW: "Hey, Dad, can I have a gallon of beer, I want to try and make vinegar"). Presumably, some vinegars (as wine vinegar, balsamic vinegar, etc.) are still produced this way; I do not know how such vinegars might be pasteurized (deliberately or inadvertantly) so as to kill off the bacteria involved. "White" vinegar (the common stuff that's essentially acetic acid diluted in water) is now non-biologically produced; no bacterial action is (deliberately) involved. Assuming that the pickles and/or olives are not preserved in some sort of yup-scale product, there should be no more (and no less) fear of bacterial contamination from the bucket than if it had held, say, margarine. - -- John W.

Date: Wed, 07 Feb 96 09:14:00 EST From: "Taber, Bruce" <BRUCE.TABER at NRC.CA> Subject: removing break vs. clarity / sucking on hoses Hi folks, On Wednesday the 7th, Marty Tippin stated that he thought his latest batch was exceptionally clear because he did a better job of removing the cold break before the wort went to the primary. I have trouble getting my mind around this concept. When my beer is finished its active stage, after 2 - 4 days, I rack to a secondary. There is a huge amount of trub (break material) in the bottom that I leave behind. I feel that if I did a more anal, opps, I mean a more thorough job of leaving the cold break in the boil pot, it would simply result in less left behind in the primary. What's the difference? Maybe the fluid dynamics types can provide a scientific expatiation, but I assume that after the active ferment stage, when things calm down, the heavy particles settle first and the very fine particles follow. Is it not true that very fine particles will take the same amount of time to settle out regardless of how much heavy stuff settles first? In other words, removing the break material prior to the primary ferment does not result in clearer beer. I know there are other arguments for removing the break material but I am only addressing beer clarity. On another note, I always start my siphon by sucking on it. I started doing this before I "knew better". I will stop if I find it causes a problem. I've been brewing for 5 or 6 years now and have never had an infected batch. So, relax ........ you know the mantra. Bruce Taber (in Canada's capital) taber at irc.lan.nrc.ca Return to table of contents

Date: Wed, 7 Feb 1996 08:44:36 -0500 From: BF3B8RL at TPLANCH.BELL-ATL.COM Subject: Price to wholesalers for new brewery HBDers: BEGIN FLAME PREVENTATIVE DISCLAIMER: I am writing this to the HBD since there are many avid readers who are also working in the beer industry. I am helping a friend put together a business case for a micro (about 15,000 barrels annually). My question skirts the appropriate/non-appropriate border for the HBD, but since the brewery is still the figment of our imagination, I'm hoping it won't offend any HBDers. My appologies to any who find my questions inappropriate. END FLAME PREVENTATIVE DISCALIMER: That said, I am looking for a "reality check" on what price a micro can expect to sell to a distributor. The only data I've been able to gather is from "The New Brewer", which showed a mean wholesale price of about $4.75/sixpack. I've spoken to several area distibutors, and they are all over the place. Some have quoted me as high as $5.00/six, and other have quoted no more than $3.75/six. Now the distibutors on the low end feel that a new micro needs to compete on price with the Sams (TM) and Pete's of the world. I disagree. A small micro need not price compete with contract brewers pumping out hundreds of thousands of barrels a year. The small micro, provided they can differentiate themselves via either product or marketing, should be able to charge a premium above what the dominant craft brewers charge. After all they are delivery only a few thousand barrels to a select market. I see this effect in the beer stores around me today -- Sam's (TM) sells for roughly $4.75 to $6 per six, and the local ane West Coast micros sell for $5.75 to $7.00 per six. (NOTE: this is not an effort to revive the Sam Adams love'em or hate'em thread!) My questions are: 1. Can anyone educate me (or point me in the direction of some literature) on the cost structure of the beer distribution value chain? 2. Does anyone have any experiences they can share on dealing with distributors? 3. Does anyone have any experiences/thoughts on what is a reasonable wholesale price range for a small micro for the next two years or so. I'm guessing that private reponses would be best here -- I will send summaries to anyone who requests. Again, my appologies to anyone offended by my business-related questions.

Date: Wed, 07 Feb 1996 09:44:28 -0500 From: Spencer W Thomas <spencer at engin.umich.edu> Subject: Re: high temp hoses I faced this problem a couple of years ago, when I used a new vinyl hose on the "hot side" of my new CF chiller. The beer tasted like plastic & I had to dump it. I then initiated a search for food-grade, high-temperature tubing. What I found was silicone tubing. This stuff is hideously expensive in small quantities, and only expensive in larger amounts. I put together an order with the help of other HBD subscribers, and bought 150 feet for about $1.25/ft. (Before you ask, it's all gone, except for my personal bit.) This stuff is rated way past boiling (400F, if I remember correctly), and can be autoclaved or baked to sterilize it. It's not pressure rated, but is fine for siphoning. The tubing I bought was made by Norton Plastics (famous for their Tygon brand tubing), and I bought it through AIN. I've since lost the data sheet and phone numbers for AIN, but any well-equipped lab should have their catalog. I had to buy it in 50-ft increments. Fisher & other scientific catalogs should also have silicone tubing, purchasable in smaller lengths, but the price will be higher (like $2/ft and up). =Spencer Thomas in Ann Arbor, MI (spencer at umich.edu) Return to table of contents
Date: Wed, 7 Feb 96 09:57:34 EST From: Mark Stevens <stevens at stsci.edu> Subject: Old book, "Chemistry of Sake Brewing" Hi folks Last fall I came across several old books and other documents on various brewing-related subjects. I xeroxed these for my own reference, never expecting to find a real use for them. As luck would have it, Santa brought me a scanner for christmas. Since I had a bit of free time last month, I decided to see how hard it would be to scan some of this info, run it through OCR software, and turn it into some machine-readable form. My test case was a book published in 1881 called "The Chemistry of Sake Brewing" by R.W. Atkinson. It provides a detailed look at the composition and processes behind sake brewing, as they existed a century ago, and includes some interesting ideas about preserving and restoring quality using a pasteurization process. Of course, processes change over time and there are probably more sophisticated analyses that could have been done if the research took place today, but nonetheless, the book represents, in my view, a fascinating examination of what is, for most of us, an unfamiliar brewing process. I have the files as a series of PostScript files, each of which contain about 20 pages. I then created a tar file of the whole series and compressed it. I apologize to those who want the files but aren't conversant in Unix file formats---you will probably have trouble moving the files to and using them on PCs or Macs. I'll try to prepare some different file formats in the coming weeks and post them on the Brewery web server, but please don't yell too loudly if it takes me a while to get to it. For those of you who know what to do with compressed tar files and who can handle PostScript, here's where you can get the document: ftp://ftp.stanford.edu/pub/clubs/homebrew/beer/docs/ch_sake.tar.Z As always, many thanks to Stephen Hansen for putting this up on the archive and for maintaining the archive for all of us to use. If there's interest in these kinds of documents, I'll scan more as I get the time (otherwise, I'll save my time and disk space for more productive purposes).

Date: Wed, 7 Feb 1996 10:14:25 -0500 From: Simonzip at aol.com Subject: Stout So last night I enjoyed my first taste of Murphy's Irish Stout from the 16 oz. 'Drought Style" can. Ummmmmmm creamy.........Just as any other maniac brewer would do with his/her first can; I cut it open to see how the nitrogen was introduced. I was surprised to see that there was nothing that physically activated it. Very close to the bottom was a small plastic cylinder of the same diameter as the can, just hanging there. So I'm guessing it must rupture (although I saw no evidence of an opening) due to some change in pressure. Anyone know the physics of this beautiful phenomena. And, why does it say on the can that if it isn't refrigerated for at least 2 hours it could gush, over-foam. And, is there any carbonation in that beer from CO2, or is it all nitrogen. I could not detect any of the carbonation I am used to. I will enjoy many more of these this evening whilst I contemplate the curiosities. Now, a brewing question: I have a stout fermenting that I will be adding lactose to at bottle time to make it sweet/milky/creamy. What amount is a good starting point. I know it depends on the amount of sweetness or creaminess you want, but I have not done this before and have nothing to compare to. I want it to be noticeable but not overdone. I'll bottle a full 5 gallons and it had an OG of 1.045. I had a recommendation of 2-4 oz. Also, what would happen to the finished product if someone added 9 oz. of lactose to the primary of a 5 gal. stout batch with an OG of 1.064? Thanks in advance (nothing witty to say today) Return to table of contents
Date: Wed, 7 Feb 1996 09:28:48 -0600 From: John Wilkinson <jwilkins at imtn.tpd.dsccc.com> Subject: Modified grains Perhaps some learned readers of this digest could enlighten me. I recently bought a bag of DeWolf-Cosyns Pilsner Malt with which I hope to brew a Classic Continental Pilsner this weekend using either Dave Miller's recipe from his book on world brews or C. Papazian's Crede Lily from his Homebrewer's Companion (if that is the title). Both of these recipes call for a single infusion mash but I wonder if the DeWolf-Cosyns malt is highly modified enough for this? Is anyone familiar enough with this malt to know? The home brew supply store owner from whom I bought the grain said it should be fine with perhaps a protein rest. Noonan said in an article in an old Zymurgy grain special issue that malts that were not highly modified must be decoction mashed. Noonan said to look at the acrospire of the grain to judge the degree of modification. I tried that but damned if I can pick out the acrospire. Maybe my tired old eyes are too far gone to see anything that small. At any rate, I have done a few single infusion mashes but no decoctions. I mash in a cylindrical 10 gallon Igloo water cooler and am unsure about trying multiple step infusion. It seems that the amount of boiling water needed to raise to each step would soon amount to too much. Any opinions on the DeWolf-Cosyns Pilsner modification level and/or the need for a decoction or multiple infusion mash? Thanks, John Wilkinson Grapevine, Texas Return to table of contents
Date: Wed, 7 Feb 1996 10:35:30 -0500 From: GSHUTELOCK at aol.com Subject: Extract Scotch Ale Recipes Needed This is my first time writing to the collective though I've been following the digest for a couple of months now. I am a relatively new homebrewer with three kit batches under my belt (brown, pale, porter) - my favorite being the Pale Ale. I've now freed up enough bottles to try something else. I enjoyed the Sam Adams Scotch Ale that came out around Christmas time and would like to try to make something similar - perhaps a bit heavier. I would appreciate if anyone in the collective has a good tried and tested extract recipe for a heavy or extract scotch ale. Background: My first two batches (brown and pale ales) were from Brewer's Best kits which I followed to the letter. They came out great - way beyond my expectations. The finished product was clear, nicely carbonated, good tasting, etc. The third batch was a Brewer's Best Porter kit which I modified to include some of the Goat Scrotum Ale adjuncts from Papazian's TNCJOHB. The results were again nice and drinkable in all respects except the spruce essence and maybe the brewers licorice I added seem to have overpowered the flavor. Is this just my personal taste or does 2 tablespoons of spruce essence seem excessive for a five gallon batch? I noticed other spruce beer recipes that didn't even call for adding this much essence. I wrote to I.D. Carlson who packages the Brewer's Best kits (Muntun & Fison products) and asked for info on their pellet hops and yeast. They were kind enough to send me the following: Classic Pale Ale: bittering hops - 1 oz Northern Brewer 6.9 Alpha Acid finishing hops - 1 oz Fuggle 3.6 Alpha Acid .5 oz Northern Brewer 6.9 Alpha Acid Brown Ale bittering hops - 1 oz Fuggle 3.6 Alpha Acid finishing hops - 1 oz Fuggle 3.6 Alpha Acid English Porter bittering hops - 1 oz Northern Brewer 6.9 Alpha Acid finishing hops - .5 oz Fuggle 3.6 Alpha Acid No good info on the Muntons ale yeast was provided by I.D. Carlson but as reflected elsewhere by people who have used this dry yeast I found it worked equally well dry pitched or rehydrated and pitched. Fermentations were extremely aggressive and over in 2 to 3 days after bubbling started. I'd tried open fermentation in a plastic bucket and also have used a 6.5 gal glass carboy with blow off tube for initial ferment and rack to a 5 gal with airlock for secondary. Both worked fine. I rapidly chill my wort to 80 deg. F (15 minutes max) with my homemade wort chiller (20' copper refrigerator tubing with hose fittings) and ice water bath. I aereate my 2 gal chilled wort as I siphon it into 3 gallons of room temp distilled water. Aereator wand is length of copper tube with T fitting - one end pointing up with cotton soaked in vodka in end (to keep out invisible nasties and dog hair) and siphon hose hooked to side coupling for wort to enter. I've primed with corn sugar or DME with equally good results - both in terms of carbonation and taste. Ferment at 68-70 degrees in dark utility room. Carboys/fermentation bucket soak completely clean with bleach/warm water solution - no scrubbing needed. I leave the the beer in the secondary carboy for another 5 days even if there is no further activity (that way I bottle on the weekend). I've bottled in 12, 16, 22 oz. bottles and 5 liter mini-kegs, all with good results (mini-kegs are a bit over carbonated as I cannot adjust amount of priming sugar when I split the batch between kegs and bottles). Any comments on my procedures - things I could improve or should change? My scotch ale will be an extract batch but not from a kit so please only provide proven recipes, I don't want a repeat on the spruce porter experiment. Also looking to try a liquid yeast (smack pack) - any recommendations for a good variety for the scotch ale? Has anyone tried using the Phil's Psyphon Starter?

Date: Wed, 7 Feb 1996 10:35:34 -0500 From: GSHUTELOCK at aol.com Subject: 5 L Mini Kegging Systems In Homebrew Digest #1954, Scott Riley writes: >I really hate the idea of bottling. I think if I bottle I won't be as = >likely to brew as much. I really need some form of a "mini-kegging" = >system. The corny system is not an option. First I'd like to say welcome to a wonderful hobby. I've used the 5 L mini-kegging system for some of my homebrews with good results, but I have to admit that the wife and I enjoy the bottling routine and get a lot of satisfaction in popping the cap off a bottle and hearing that reassuring sound of escaping CO2. So don't discount bottles so fast. Besides, in a bottle you can see the clarity of the brew and the yeast residue at the bottom that lets you know that the aging is progressing okay. Mini keg pluses: - Fast and convienient, it only takes about 4 of these to do up a 5 gallon batch. The rubber bung is reusable. - Takes less priming sugar/DME (about 1/3 cup corn sugar for a keg instead of 3/4 cup for bottles. - Fits in standard fridge and normally easy to dispense. If CO2 cartridge is used to pressurize the keg the beer will keep for a few weeks without oxidizing or going flat. Mini keg minuses: - Tendency to generate a lot of foam, you have to be careful with that CO2 adjustment. - If you split a batch between bottles and kegs (which I often do) you pretty much have to prime for the bottles which means the kegs are going to generate lots of foam, at least initially. - Cost and short life span of CO2 cartridges. Hand pump pressurized kegs have to be consummed right away (good for a party maybe) or the beer goes stale. - Leaky bungs and CO2 cartridges. - Kegs may not fit back into fridge once the tapping system is installed. I find it comes out better if I let the excess natural CO2 escape as I tap the system. Then repressurize with just a little CO2 from the cartridge and shut it off again. If not enough pressure, repeat until it comes out okay. Don't crank the valve open and leave it open. The lowest setting that gives you a slight hissing sound seems to work just fine. I still get lots of foam which I attribute to over priming (1 inch of beer and the rest foam in a room temp or frozen mug) and have to wait for it to settle. You should have better luck with less priming sugar. If you're inpatient you can decant the beer into a pitcher, let the foam settle and then fill the mugs. All things considered, I prefer bottles and if you establish an organized routine for cleaning, sanitizing, filling, capping and labeling can add to the overall enjoyment of packaging your just brewed elixer of life.

When siphoning from a carboy I usually use a - carboy cap and sanitized milk jug (like suggested in - Brewing Techniques several issues ago). I had used - Charlie Papazian's "water in the siphon hose" technique - previously, but am leery of using it with unfermented - wort. Needless to say, sucking on the siphon hose is - also out. Try asking around at your local homebrew shops for a product called "The sucking thing" (standard disclaimers apply). It is IMHO a great tool for siphoning without risk of contamination. I used to use the water in the hose trick (what a pain) and have found this to be both cleaner and easier. The "thing" is basically a ventilated mini-baster that you use along with a hose clamp to start the flow. The clamp is used to pause the flow while you remove the sucking thing. Pricing should be around $12. Now for my question, Someone recently ask about a recipe for making a dry hard cider. Does anyone know how to make a sweet hard cider? When I tried one it automatically went dry since the fermentation eats the sugar. I am not fond of sweet and low or equal, so I don't want to add either to my completed product. Adding sugar to the final product just boosts the carbonation without sweetening it. Thankfully I don't ever try to make sweet beer. Return to table of contents

How do I start my own yeast cultures? I read the section in "The New Complete Joy of Homebrewing" on it but it didn't mention how to take yeast from a primary and re-culture it for the next batch. Also, can you just keep on doing this? Take yeast from each batch and hold it over for the next one? Thanks, Tracy Thomason 102472.1404 at compuserve.com Return to table of contents
