---------------------------------------------------------------------- Date: Sat, 29 Jul 2000 12:52:44 +0200 From: "Dr. Pivo" <dp at pivo.w.se> Subject: Some alternate views on hop and alcohol levels. Some recent postings on massive hopping rates awakened a response from Tom Logan. Responses to his posting were by and large negative, ranging from it's content to it's single paragraph construction (it's ok Tom, I misspell every third word, and generally lay out my sentences in non-English syntax). I must say that I agree in most part to at least the principle of his leading comments. I make a trip to the states about every other year, and my continuing impression of micro breweries there, is that their beers are "over hopped", or more succinctly, don't have enough other flavours to support the chosen hopping rate. I think this stems from my "three stages of brewing" theory. Stage I: Fumbling. The new brewer is really in a hit or miss operation, and can produce any odd flavour you might imagine, and amidst this will turn out some truly brilliant things.... but they won't be repeatable. They just don't have control yet. Stage II: Extreme. The brewer now has a bit of control over the process, and generally goes "pretty wide in the turns" in some aspect of the brewing. Some go for as high an alcohol content as possible, others try and pound as much dark grains as possible into the brew, but most opt for extreme hopping rates. Having been accustomed to the relative paucity of flavours in commercial brews, this is sort of a "backlash" reaction. Since hop aromatics are never present in long stored beers, this can be a pretty thankful area to proceed in to make a "unique" beer. Stage III: Refined. Getting a better hand on the whole process, the brewer now tries to keep a balance between sweetness, malt flavour, bitterness, hop aroma, and any esters and other tricky stuff that may be milked out. So... I consider the hopping rates at micro breweries to be a "childhood disease" of a relatively new industry (I am quite sure that some people will be getting their "8====>" in a "&" over that comment). I would stress that brewing at home, allows one to do exactly what one wants, in any extreme direction at all. I'm sure most people have had the experience of having someone home who "doesn't drink beer", only for them to find that they quite enjoy your richer flavoured version. It's hard to win over those virgin palates with half of Mount Hood in the kettle, and I think it is a pity that we are missing the opportunity to raise beer's status among a wider population. Having said that, I find hops reputation as a soporific highly overrated. Why just last weekend, I was sitting in the cellar of a micro, and we were tanking ourselves liberally. We had no problem chattering and solving the world's problems until 5 o'clock in the morning, and I was quite chipper as I hopped onto a bike and pedaled away. As to hops having any inhibative powers on either libido or performance... I've never heard that one....and as I started pedaling away yodeling "De la Sier-ra Moreno...." (Just warming up for the "AY-AY-AY-AY!" part). I crashed over onto the grass (who says you never forget how to ride those things once you've learned). I came nose-to-nose with a hedge hog, and I was really prepared to invite her home, until my friends came and convinced me that these trans-species things never work out. In fact, when I think about it, almost every time I've been guilty of "thinking with the wrong head", it seems to have been after quite a few beers, which tends to contradict the hop hypothesis and the limp noodle. Admitting my poor connotative understanding of English; I'll be willing to take on the "drunk" title that everyone seems to be shying away from like a booger on an hors d'oeu'vre platter.... why, as proof of that, I was invited to dinner the night after the brewery debauchery, and was served a glass of red wine (there was no beer). Now I am of the belief that the best thing to do with a bottle of good Bordeaux, is to make a "coq au vin" and eat it drinking a pilsner to it. A good sauterne makes a nice sauce with dijon, to serve to a freshly caught trout and some new potatoes cooked in dill..... (did I forget the pilsner part?)... but I drank that glass of wine anyhow, 'cuz THERE WASN'T ANYTHING ELSE.... what a sinner. There has been requests for some scienterrific evidence about blood alcohol levels and driving abilities. I've been involved in that kind of research, and I'll tell you it's mostly " at ~ " (this particular "nasty ASCII" must be read with the head tilted to the right, and one must imagine the sound of horses hoofs and a wind bearing from the right... admittedly a bit far fetched, but I already got in the "knot" one earlier). You see, alcohol is a complicated drug (toxin) and exhibits characteristics of both a stimulant and a depressant. The main "sooky-la-la" comes during the "rush" of increasing alcohol levels to the brain, while one accommodates pretty well as levels are falling. In other words, in all measures of "degree on drunkenness" such as reaction time, balance, short term memory, and something called "diadokinesis" which just means being able to rapidly change movement patterns, you'll score worse at a blood level of .05 on the "way up" than you will at .09 on the "way down". In other words it's a pretty crappy indicator of how impaired you are. Quite frankly, I think it was a better method for the suspecting officer to do his on site neurological evaluation, and if suspecting that the driver was impaired, doing an alcohol level. I certainly think I can recognize a drunk, and I think a trained police officer can as well.... but this would require "common sense", and trusting that a trained professional can do his job, and we are trying to outlaw those things at the moment... in fact there is a piece of legislature up for vote at this very moment which will require finger guards when nose-picking... why just last week in Vermin Ohio, a guy stuck his fingernail right into his brain. I suppose we will have to accept the breathalyser method since it is a "no-brainer", and besides, what else have we got? In the days when alcohol blood analysis was a hard thing to come by, we had to rely on such primitive methods as "open container" laws. And believe it or not, there are still some underdeveloped parts of the world where those laws are still in place. Dr. Pivo Return to table of contents
Date: Sat, 29 Jul 2000 19:35:20 +0800 From: Edward Doernberg <shevedd at q-net.net.au> Subject: drink driving limits i probably shouldn't continue this barely beer related thread that has no specific relevance to home brewing but i feel i should contribute. if for no reason other than to show that even if Australia is a land of relatively heavy drinkers (many people i know drink 1-2 every night) we don't all condone drinking while driving(and i suspect nobody hear dose either). in western Australia the limit is now .05% with an increased penalty if your above .08 and i believe this is good. i know at .05b i am not thinking as clearly as i could be. i don't think the limit should be any lower because i want to be able to have 1 beer at the pub and drive home (with full strength beer that's about all i would trust myself with) and there are considerations like liqueur in foods and the natural yeast in your intestine. mouth spray will already put you over if you use it immediately before the test but it dissipates quickly enough (some people think it will reduce the reading). what i think we need if anything is stronger penalties. especially above the .08 limit and more testing of drivers. Other than that there are some rules I relay don't get. E.g. it is legal to walk around the streets completely plastered (I work ate the serves station doing graveyard shift on Friday and Saturday so I see them all) but it is illegal to have an open bottle of alcohol with you even if your sober. The penalty is $50 but not cops will allow you to pore it out. Why do I have to deal with drunks trashing the shop and bleeding all over the place (did happen) and you cant carry a bottle from one party to the next. Edward Return to table of contents

Date: Sat, 29 Jul 2000 09:45:09 From: "C.D. Pritchard" <cdp at chattanooga.net> Subject: re: brazing copper to stainless? N.P. Lansing asked if any one knows of a brazing alloy that is compatible with both copper and stainless steel? Don't know about brazing but I've used StayBrite solder and the liquid flux that comes packaged with it sucessfully on knives (brass and nickel silver to SS blades and a 1/2" Cu pipe coupling to a hole in a < 1/16" wall thickness SS tank). It won't be as strong as a welded, brazed or silver soldered joint but if the joint has enough surface area and stress is not severe, it'll work fine. I like the stuff because it doesn't require alot of heat- a cheap propane or MAPP gas torch is usually enough and is stronger than ordinary lead/tin solder. Hobby stores that handle RC airplane supplies usually have StayBrite. Flux specifically made for stainless steel works a bit better than the flux supplied with StayBrite tho'. Sand the joint surfaces first and then degrease with acetone or something that won't leave a residue. c.d. pritchard cdp at chattanooga.net http://chattanooga.net/~cdp/ Return to table of contents

The term seems to be used with some ambiguity and inconsistency at times. At first guess, I would have thought that it was any fermented alcoholic beverage that was produced (largely or partially) from a "malted grain". Anyone with a good definition of this term wish to fling it at me? Thanks Scott Tampa, Fl. Return to table of contents

That would appear not to be strictly true. Steve Michalak of A/B wrote a couple of days ago: >Budweiser is mashed-in at 109F and converted and 147F. I have brewed at least two very successful, very well attenuated beers at 119/148F (followed by 162 foam stand and 170 mashout rests), and conversion appeared to be complete before the mashout. Like amylase activity, starch gelatinization is not a yes/no kind of thing at any one tempterature. Besides, I rather thought that the barley starch geleatinization temperature was in the lower 140s, but I don't remember. I s'pose I could look it up.

Date: Sun, 30 Jul 2000 08:33:23 -0400 From: Dave Burley <Dave_Burley at compuserve.com> Subject: Spanish Moss Brewsters: Del Lansing suggests using more Spanish Moss in his brews to reduce the haze. Really! Maybe I should just go out and pull some off the trees south of here! {8^) Of course, Irish Moss, normally used in Britsh ales, isn't moss but seaweed. All this discussion of tannins and haze and Del's comment that he never heard of a ( pure?) tannin haze reminds me that one item that has not been part of this running discourse is that tannins form hazy complexes with metal ions like iron, etc. This may also be a factor in your discussion. Don't know if the heating would improve by precipitating these hazes, but I assume so as it is a common technique in quantitative gravimetric chemical analysis ( boy, that was long time ago!) to age the precipitates by using heating and time to get a better recovery by growing the precipitates' particle size to where it could be filtered better. I suppose using distilled or deionized water might help in understanding this issue. Keep on Brewin' Dave Burley Return to table of contents
Date: Sun, 30 Jul 2000 12:45:15 -0400 (EDT) From: Some Guy <pbabcock at hbd.org> Subject: Re: Malt Liquor??? Greetings, Beerlings! Take me to your lager... Scott Church writes... > I have a question about the term "malt liquor". > The term seems to be used with some ambiguity and inconsistency at times. > At first guess, I would have thought that it was any fermented alcoholic > beverage that was produced (largely or partially) from a "malted grain". The explanation comes from "Tax Man", as performed by the Beatles (although SRV's rendition is quite appealing, too...), and is interpreted as follows: "Malt Liquor" is simply a political label intended to reclassify a beer into a higher tax slot. Generally, a beer is classified as a malt liquor when its alcohol content is above some number very scientifically set by the opinions of politicians. Also, generally speaking, the beverage is derived, at least in part, from malt. Note that there is another classification of "malt beverage" for those insipid things which don't classify as beer ("wine" coolers made from malt-derived ethanol and fruit juices, for instance, or "Zyma". Probably "Tequiza", as well.). It's arbitrary, it's assinine, and it's all ours (US). - -- - See ya!

Date: Sun, 30 Jul 2000 16:19:03 -0400 From: Jim Bentson <jbentson at longisland.com> Subject: Coconut in Beer & Aussie Posts Darrell Leavitt recently asked about using coconut in beer. I made a coconut Porter from a Zymurgy recipe in 1998. The original recipe had won best of show at the AHA conference in 1998. One thing, get the dry coconut from a health food store as the supermarket type has propylene glycol in it and I would not put that in my beer. I had no problem due to oil using this type of coconut. In the recipe I used, there was 1 lb of coconut for a 5 gal batch. The coconut was first toasted for 10 min at 325 deg F. Use a baking sheet and stir while toasting. The coconut will have a golden color when done. Add to the secondary. The 1 lb in 5 gals gave a very noticeable taste. Too strong for myself and also many of my friends who appreciate good beer. I would try 3/4 lbs to start. Good luck! One problem I did encounter is that the coconut floats in the secondary. I lost more beer than usual when racking from the secondary to my bottling bucket due to the coconut blocking my syphon cap at the end. You could solve that by doing a tertiary fermentation and straining the coconut out of the secondary liquid at the end ( or just make an extra 1/2 gal). Concerning the spate of Aussie non-beer posts; I only go through the HBD once a month and am surprised at how much wasted bandwidth is being tolerated relative to the Aussie's attempts at humor. Come on guys, there are many pertinent posts being pushed back a day or two due to the constant stream of Aussie posts with nothing in them. I know I can "page down" but almost 1/4 to 1/3 of the latest issues are pure nonsense.What is really a problem is reposting something not related to beer just to make a one line comment. Now I have to skip the same article twice! Anyone else feel the same way or am I getting too old for the Digest??? Jim Bentson Return to table of contents
Date: Sun, 30 Jul 2000 18:34:21 -0400 From: Phil & Jill Yates [mailto:yates at acenet.com.au] Subject: Building Backyard Bathyspheres In Burradoo Rightly might you ask yourself the question : "What the hell is this lunatic up to now"? Well, Wes Smith and I have come to the conclusion that the only way to escape whinging wives and children, howling dogs and demented cats, and truly enjoy a peaceful homebrew, is to build ourselves a bathysphere in which we can sit and contemplate. The other great advantage is ultimate control over carbonation. But it is in this area that I have a few questions. Let's say you have gassed your beer up at 30psi, rather overdone to be sure. Sitting in our bathysphere, Jill struggles on the external billows until Wes and I (sitting comfortably in our smoking jackets) are enjoying an atmosphere at 30psi. What has happened to our beer? Will it now be flat? Conversely, Wes and I enter the chamber with our CO2 regulator carefully set at 15psi. In more predictable fashion, Jill pulls the big lever which immediately evacuates all atmosphere from the bathysphere (of course, Wes and I were not smart enough to incorporate oxygen masks - in short, we've had it chums!) My dying question, as we sip our last in a total vacuum is "what is now the reading on the CO2 regulator"? Sorry to be so inquisitive on a Sunday night. But I've run out of beer!!

Scrub any memories of the Port being a rough spot, it's been done up over the last ten years. The Port Dock is also a great place for a feed. I think there were four Brewpubs in a rush about ten years ago, one remains. Say g'day to the Brewer, Stephen Nelson, and give him my email address. Paul, I referred to Rankine's "Making Good Wine" on Sorbate. Maximum legal level is 200mg/litre, though apparently detectable at 130mg/litre. Sorbistat K is 75% sorbic acid and is 56% soluble at 20C. It doesn't work on all yeasts, so you may need to filter or pasteurise. Effectiveness is low when yeast concentration is high - so filter or rack thoroughly first. Geranium taint is caused in red wines that undergo a malo after dosing with sorbate. The rule here is also to ensure the wine is well protected with PMS and low pH - bacterial action on sorbate is apparently nasty.

I al hoping to do an extract batch soon with the addition of Maple Syrup to as Emeril say's "Kick it up a notch" that is why i was asking about the Champain Yeasts as the Syrup has a ton of fermentable sugars, we shall see how it goes. Now on to the other part of this post. recently one of you asked for details about Rail City Ale. as a Vermont resident I am familiar with Rail City in the following ways, it is a great series of brews, and, THEY CLOSED UP SHOP THIS MONTH!!! what a pain in the ..... if you can find the following beer where you are i suggest you try Otter Creeks Pale ale, not a bad sub. but certainly no Rail City. Sorry for the bad news and thanks again all for the help. Wishing you all Tight Lines, Russ Return to table of contents
