I don't claim it to be the last word by any means but most of the issues regarding how much carbonation one can expect for a given amount of glucose and sucrose are covered; in addition, I report some experimental data showing that water adsorption increases the weight of sugar by wholly trivial amounts, so that weight *is* better than volume-- and these trials were done here in Sydney where it is Bleedin' humid during the summer too.

I have enjoyed this beer on many occasions but it is really hard to find with any regularity in these parts. I am new to homebrewing, having brewed two batches with Coopers kits.

From: Jay Williams <jayw7 at airmail.net> Date: Wed, 17 Jul 1996 17:57:30 -0500 Subject: Refrigerator vs. Upright Freezer Maxwell McDaniel asks: Which is better, refrigerator or freezer? And if it's a freezer, do I go for upright of the other kind (coffin style)? Can anyone give me guidance on how to hook up taps and CO2 lines without disturbing any freon coils? Reply: Since I own both an upright freezer, and a refrigerator for brewing purposes, I will give you the pros and cons as I see them. The pros of an upright freezer: With an appropriate add-on temperature controller, you get a better range of temperature control than with a refrigerator. There is no wasted space as in contrast to a refrigerater, which has the freezer space above, which is not really usable. The cons of an upright freezer: The upright freezer owned is a not a frost free freezer. This means that that during the hot and humid days of summer in Texas, you have an unreasonable amount of condensation that accumulates on the freon coils that are under each shelf. Anything in the freezer made of something that will mildew, will do so. You cannot store six-pax holders in the freezer for this reason, and the bottle lables will end up less than pristine for the same reason. However, if you store your fine cigars in a ziplock baggy on the upper shelf, the freezer makes a reasonably good approximation of a humidor, at least during the summer months :-) Once the heat breaks in October, condensation is usually not a problem. The shelves on a non-frostfree freezer are fixed because they have coils underneath them. I have read, in the Homebrew Digest, about people bending the coils and shelves down to make for more headspace, but each time I decide to attempt this project, tommorrow always looks like a better day to start this. I was unable to find a freezer that would allow room for anything except for plastic brewing bucket, so at least on a non-frost free freezer, you will have to re-engineer to accept upright Corny Kegs. An upright frost-free freezer eliminates most of the problems mention above. While I do not own one, it is believed that the shelves are adjustable. For this reason, your Corny kegs will easily fit. You have no condensation problems. You have the extended temperature range that refrigerators do not allow. Unfortunately, they are generally more expensive. Chest type freezers would be a problem for me because bending over at the waist to lift 5 gallon containers out would cause back problems. The pros of a refrigerator: Almost all of the used ones left on the used market, are are frost free. Unless you wish to lager below say 40 F, extended temperature range is not a problem. They are cheap. The cons of a refrigerator: The freezer space is wasted. Conclusion: Buy a frost free upright freezer, that has adjustable shelves. You will pay more, but you will have a more versatile brewing apparatus. In fact, I would buy one for myself, but my wife is currently watching my homebrewing budget very closely :-) Hoppy Brewing, Jay Williams Return to table of contents

From: Daniel Louis Lanicek <dll0001 at jove.acs.unt.edu> Date: Wed, 17 Jul 1996 19:45:43 -0500 (CDT) Subject: Gelatin Homebrewers, I recently read in BYOB that by adding gelatin to secondary fermentation you can increase the clarity of the beer. The directions say to boil 1/2 to 3/4 of a packet of unflavored gelatin in a cup of water, then add it to the carboy. Does this work? Is it worth it? I recently tried this with a stout I brewed, but it's a little difficult to see if it worked with a dark stout.

SO is having major fit about the bottles that are filling the house and wishes me to rid our house of these **** things. Little does she know that kegs will take up more room if you include the refrig. Well, I would like any info/ suggestions on how to cool the kegs. I would like to build a bar on one end of my living room to house the fridge and kegs along with glasses and other beverages. Would not like an upright fridge in this area, just something small enough for say, three kegs. Has anyone built such a beast? Have seen the advert for a "beer home" which looks about like an old Ice box with the taps on top. Would you tear the guts out of an old fridge and build a new cooler for this application.

From: Wallinger <wawa at datasync.com> Date: Wed, 17 Jul 1996 22:12:52 -0500 Subject: Too Much HBD OK, so we'll waste gobs of bandwith decrying the length of the HBD. I for one second this motion, and have decided to be hypocritical and waste your time and mine to get some issues off of my chest. The fate of my prior message to the 'janitor' is unknown, so I offer these comments to all. I was gone for two weeks and it took me two weeks to catch up by one of those two weeks. After two weeks of saving each and every HBD I decided to jump ahead to see if Al and Dave (and Steve and Tracy) were still at it. This is like watching a soap opera - if you miss watching a few days you find that you really haven't missed anything. One reader advises that this forum is like a newspaper, just page down through items that are not of interest. Unfortunately, journalism isn't what it used to be. That advice takes the heat off of the contributor to make a useful contribution. I say bring back the days of limited throughput so people who submit comments have to THINK about what they are saying before saying it. By the way, I have trouble picking up my newspaper anymore because so-called journalists have more political crap to offer than real news. Where does this leave us? Well, I for one am beginning to question the value of the HBD. After all, I may have time to tackle reading all of the reference books on brewing in the time I would otherwise spend on this dribble. That way I would have more confidence in the information I was receiving than much of the heresay that is published here. I can only suggest that folks show a bit more restraint and thought when they post publicly. I personally trust you all to work through your differences of opinion (and observation) privately so that you can reach concensus (or an agreement to disagree), followed up with a summary of the pertinent facts, issues, opinions, datapoints, etc that you raised with each other prior to the public post. And now I must apologize for this. Yes, this was extremely hypocritical of me.

From: Todd Kirby <mkirby at bgsm.edu> Date: Wed, 17 Jul 1996 23:18:42 -0700 Subject: pH Meters In reference to Esbitter at aol.com questions regarding pH meters, it would probably be a good idea to store the electrode in a buffer with a pH as close to the middle of the range you typically measure as possible. Don't store the electrode in dH2O, especially if it is the membrane type. You might try Fisher Scientific as one source. Obviously, make sure the solution is non-toxic, and rinse well with dH2O before using. If your meter can be calibrated, it's probably a good idea to keep some around anyway to insure your instrument is working properly. OK, I guess everyone can get back to such relevant brewing discussions as Beer in Spaace. (Geesh, and people are complaining about HBD being too long). TK Return to table of contents

If the hops are not thoroughly dried, they will rapidly mold (believe me!) and spoil. Hops apparently gain in quality from a period of storage; as I recall, oxidation in the bale is a necessary step in producing good flavor (once again, check a good text, but this was garnered from conversations with hop growers in the Willamette Valley). There may be good, non-obvious reasons why hops are still dried instead of being frozen. >>>>>> In addition to mold decomposition, poor levels of hop oasting can also result in that (rapid, rabid?) other form of oxidation -- combustion. Hops have quite a high redox potential (read: signifcant stored energy), and microbial decomposition has been known to lead to smoldering combustion, which then leads to flaming combustion, which then leads to end of warehouse. I beleive HopUnion has lost two hop storage facilities to this evil. Also seems that this process is effectively eliminated below 10% moisture content (dry weight basis). Hop bales are routinely cored and checked, and if 10% or higher they are broken down. Ideal storage moisture is around 6-8% if memory serves, which is unlikley. It is, however, below ten percent. Homebrewers needn't worry much about this though, as baling appears to be a requirement for creating microsites capable of spontaneous combustion (a process that is quite poorly understood from a fire research point of view). So if you aren't baling them things, dry them well anyway and watch for mold. Interested parties are encouraged to search past HBD (late summer 1994) for a study of dryhopping fresh vs. dry homegrown hops. In this instance, the dried materials were judged a superior form, albeit with some obvious control variable differences other than moisture content possibly confounding the (percieved) effects. cheers, - --dave Dave_Sapsis at fire.ca.gov "Think you used enough dynamite there, Butch?" - --Sundance Return to table of contents

I spent 10 days in Belgium a couple of weeks ago, and tasted over 50 different beers. Most of them are not available in Norway, where I live. I took a special liking in the hoppy trappist ORVAL (I brought with me a few), and would like to brew something close. Another hoppy belgian beer I would like to imitate is DUVEL. Any recipies? I'm an extract/specialty grain brewer, and have produced 7 or 8 batches so far, most of them good. BTW, Belgium is really Beer Heaven. Great beers, great cafes.

From: Bill Ridgely FTS 827-1391 <RIDGELY at A1.CBER.FDA.GOV> Date: Thu, 18 Jul 1996 09:21:35 EST Subject: RE: Pre-Gelatinized Wheat? In HBD #2111, the subject of unmalted wheat in witbier was discussed: >John Varady writes: >Unmalted wheat should be boiled for a couple of hours >prior to mashing, and it will take all your strength to >mill it! Scott Bridges replied: >Is this correct? Does anyone else pre-gelatinize >unmalted wheat for a Wit? I've read that unmalted grain >adjuncts need to be pre-gelatinized before mashing for >other styles. However, I've made a number of Wits and >I've never seen gelatinizing as a requirement in any Wit >recipe. My brewing partner Wendy Aaronson and I had gotten several different opinions on this subject when we planned our witbier. We finally decided to pre-boil the unmalted wheat and steel-cut oats in the hope that it would help with lautering. These grains were boiled for about 20 minutes and then added to the mash tun along with the requisite pilsner malt. We also used a 45 minute protein rest at 120 degrees F per the recommendations in Phil Seitz's excellent Zymurgy article on Belgian brewing. The result? The wort lautered without a hitch, and the finished beer turned out crystal clear! For most other styles, this would have been a welcome result, but for an intentionally cloudy beer like a wit, it was a bit disconcerting. Nonetheless, the beer was extremely tasty and ended up taking 1st place in Belgian Ales (and 4th Best of Show) at this year's Spirit of Free Beer competition (beating out Jim Busch's illustrious Esprit de Boire by a hair). Next time we brew a wit, we'll skip the pre-boiling step and just go with a long protein rest. BTW, I feel the most important variable in brewing a witbier is the selection of the coriander. There are many grades on the market, so if you can find high-quality, fresh coriander in your area, use it instead of the industrial-grade McCormicks brand found in nearly every grocery store. Also, be adventurous and use a good ester-forming Belgian yeast. We used La Chouffe, and the aromatics produced by this yeast nicely complimented the coriander in the beer.

The reason I'm asking this is that I need to monitor the acidity of a mead as it ferments, and I would like to just take a quick pH reading instead of titration. My references suggest a final pH of about .60%, and that it is best to save adjustments until bottling to keep the yeast from being shocked (I'm using ale yeast -- not wine yeast).

By large I mean >10-20 gallons or so.. 5 gallons at a time just doesn't cut it anymore - >especially for wine, which ties up a fermenter for 6 weeks or so. I would try using a large plastic bag in any container that will hold the bag. After filling, pitching, and aerating, I would place a sterile cotton ball up top and gather the bag around it and tie it closed so that the carbon dioxide can escape through the cotton ball. To rack, I would punch or cut a small hole in the bag, insert racking cane, etc.. This would minimize any disturbance to the grunge from fermentation. Might be able to use a rubber stopper and airlock for the secondary fermenter if you can rig up some way to hold it upright. Don't know how sterile the new bags are but I read somewhere that they are considered fairly sterile. Would just try it and see how it goes. The main thing going here is CHEAP and easy. Also no cleaning needed, just toss when done. No - wait, do not toss yet, use for trash, fill, then toss! Ron Return to table of contents

That half filled bottles undercarbonate is no mystery, the added gas from priming fermentation will only half the gas per unit volume to a half filled bottle.

This doesn't correspond w/ my lager experiment posted here around the beginning of the year. I, and later AlK, found that very full bottles carbonate much more slowly than normal or underfilled bottles. Note that I'm NOT saying your wrong, just that we have three experiments w/ different results. Al determined that overfilled bottles undercarbonate. I strongly suspect that my final carbonation was a bit low in overfilled bottles, but not by a very obvious amount. That overfilled bottles can undercarbonate and carbonate slowly *may* be attributable to poor yeast growth at higher pressures. A known effect. Need more experiments here guys. Perhaps the yeast strain used has an effect. I used Wyeast 2308.. Al ? Brad ? >Bottom line for me; I now leave almost no head space (easy to do with ... >reducing oxidation potential. This has worked well for me for the I doubt the oxidation potential is a big issue with normal fill levels and bottle conditioning (I do attempt to eliminate headspace air). >From experience, bottle conditioned beer just doesn't oxidise much. I suspect that yeast drive the redox potential of the beer toward the reduced state, and consume some free oxygen along the way. How much oxygen might yeast reasonably consume in primed beer bottle ? Tracy ? OTOH bottles filled from kegs w/ various filler apparati do have the potential for serious oxidation problems, and I've experienced substantial oxidation in such bottles after as little as 4 weeks in a fridge. Commercial breweries back in the 1940-1960 era used to go to great lengths to try to eliminate oxygen including adding .25 to .5 Units of glucose-oxidase enzyme per ounce of beer. I suspect HB fillers are no better, probably worse than these old bottlers. Modern commercial bottling equipment is more than an order of magnitude better at eliminating included oxygen.

From: "Jim Hodge" <Jim_Hodge at ilsc.com> Date: 18 Jul 1996 09:20:48 -0500 Subject: Raw wheat and Wit beers Raw wheat and Wit beers A quick comment on whether or not to boil/gelatinize wheat for a wit beer. Others have commented that it is not necessary and this is correct. Among adjunct grains, wheat is relatively unique in that its gelatinization temperature is sufficiently low that it will gelatinize at normal mashing temperatures. There is a table that indicates this in de Clerck's book (or it may be the Practical Brewer, I'm playing hooky from work as I write this and don't have my books with me). One other point, the wheat pretty much does turn into cream o' wheat during the mash and lautering can be a tedious and painful experience. A way to help this out is to add a few handfuls of rice hulls at mash out. I now use this as part of my SOP when I brew with wheat and it works great.
