---------------------------------------------------------------------- Date: Tue, 26 Mar 2002 01:16:47 -0500 From: ensmingr at twcny.rr.com Subject: light-struck beer A HBD'r recently asked "... what type of light causes skunkiness in beer? Incandescent or fluorescent? Would the red bulbs used in photographic dark rooms have the same affect?" UV and blue light are the worst. In this part of the spectrum, incandescent light typically has less output than fluorescent. However, there is great diversity in the spectral output of fluorescent lights. There's warm white, cool white, and many others. Red light would have little or no effect on beer skunkiness. For the more technically minded HBD'rs ... 1. Look at: http://home.twcny.rr.com/geomanagement/ensmingr/menagerie.html#a07 . 2. See the recent article (abstracted from MedLine below): - --- J Agric Food Chem 2002 Mar 13;50(6):1548-52 Role of riboflavin in beer flavor instability: determination of levels of riboflavin and its origin in beer by fluorometric apoprotein titration. Duyvis MG, Hilhorst R, Laane C, Evans DJ, Schmedding DJ. Laboratory of Biochemistry, Wageningen University and Research Center, Dreijenlaan 3, 6703HA Wageningen, The Netherlands. A method for the quantitative determination of riboflavin levels in beer was developed. The method is based on the quenching of riboflavin fluorescence, which occurs when riboflavin binds to the aporiboflavin-binding protein from egg white. The method does not require any pretreatment of the beer before analysis, other than dilution, and proved to be simple, reliable, and sensitive. The lowest concentration that could be detected was approximately 10 nM riboflavin. The possible interference of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) with the determination of the riboflavin content of beer was excluded, because beer contains only a very small amount of FAD (0.03 microM) and no FMN. The riboflavin levels of the types and brands of beer investigated were in the range of 0.5-1.0 microM. The origin of the riboflavin in beer proved to be the malt. Hop and yeast hardly contributed to the riboflavin content of beer. Besides its use in the determination of riboflavin levels, the aporiboflavin-binding protein also provides a way to remove riboflavin from beer, which reduces the light sensitivity and the related lightstruck off-flavor formation in beer. - --- Cheerio!

From > what I read, however, that company will do some/a lot/all of that for > you, but I did not see price information on that aspect. If someone > gives this a try, I surely would like to hear the story! This is what TMS quoted me for modifying their conical hoppers: Cut out bottom or drill hole = $30 ($5 each / $25 setup*) Weld customer supplied ferrule or nipple = $80 ($30 each / $50 setup*) *Setup charges divided by the number of units ordered. An alternative to the expense of welding would be to invest in a stepdrill bit and go to a place like www.bobbrews.com that carries Zymico weldless hardware. If you do that, the big problem you're left with is making a suitable stand for your conical. But as Brian Lundeen, <blundeen at rrc.mb.ca>, notes, "brewers who are serious about improving their beers will spend their money on temperature control before buying a conical." After wrestling with "to buy or not to buy" conical, I'm inclined to agree with Brian.....with the super hot summers we get here, I'd be wise to go that route first.

Date: Tue, 26 Mar 2002 06:49:30 EST From: Brewmiker at aol.com Subject: Barley Wine Ale I have been fermenting a Barley Wine Ale for about three and a half months and I think it's about played out. I want to bottle this in 7 oz. bottles. I have never so thoroughly fermented a beer before and am worried that there is no live yeast left for carbonation. What would be the best way to ensure I get some carbonation in this beer? Although I have the ability to keg beer, I don't have the equipment to bottle from my keg.

Date: Tue, 26 Mar 2002 07:07:18 -0500 (EST) From: Steven S <steven at 403forbidden.net> Subject: Re: Einen Kleinen I've actually got a Klein book, not for the flowery prose but instead the pictures of the beer. There is actually a good basis for this "style" of reviewing. Many credit J Gordon Holt for bringing it to the masses when he started Stereophile magazine way back in the fog of history. He felt the need for the magazine to describe in words what reviewers heard. One of my favorites is http://www.stereophile.com/showarchives.cgi?292:2 "Maura O'Connell's Wandering Heart (Hannibal HNCD 1410) makes a good case for the No.39's strengths. Her voice is unusually rich and vibrant, yet powerful at the same time. It has a richly layered complexity not unlike the taste of a fine Islay malt, a taste that can initially be overwhelming-but relax, and that first intensity is replaced with successive revelations of smoky warmth, then a hint of sea iodine and salt, followed by herbs and wildflowers that linger on the tongue. With McConnell, the initial strength of her delivery is supported by a smoky warmth of its own, and her intelligence and empathy also linger in the ear long after the song is over. That's how she sounds live-and it's how she sounds on the No.39. On some CD players that strength comes across as a touch of hardness, and the flowering subtleties are obscured in the digital opacity that our friend Fremer rails against every month." I dont know if we just heard a description of a song or something out of Klein's books. Hard to think he is reviewing a expensive cd player. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Steven St.Laurent 403forbidden.net steven at 403forbidden.net [580.2, 181.4] Rennerian _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Return to table of contents
Date: Tue, 26 Mar 2002 07:24:41 -0500 From: "RJ" <rjdn4 at msn.com> Subject: Attn Steven Alexander - Question on decoction mashing Hi Steve (& Everyone), I just finally finished reading Steve's article on decoction mashing in Zymurgy. Every time that I read about decoction mashing everything sounds great, except there's this one tiny little thing that always BUGS me. Every article, including yours, Steve, talks about the method as being a way to "step" mash before thermometers and that makes sense. But, what doesn't make sense, is that you all state that the decoction(s) is pulled and then held at 158F for so many minutes and then brought to a boil for so many more minutes. This is then added back to the mash to raise the whole amount to temperature X. Okay, so here's the question: If they didn't have thermometers, how'd they know when they were at the first rest of 158F, prior to boiling the decoction? What did they do, stick a willow branch in it and watch it curl or what? I'd would really like to know. Ciao, RJ Lakes Region of NH Return to table of contents

Date: Tue, 26 Mar 2002 09:35:16 -0500 From: "Dennis Collins" <dcollins at drain-all.com> Subject: Re: Fermentation Temps & Yeast Abuse First: Caryl Hornberger expresses some concern over the coming Indiana summer temps on the quality of his beer. Rightly so Caryl. High fermentation temps can have a significant impact on the taste of your beer. In fact, controlling the fermentation temp has had the biggest impact on the quality of my beer than almost anything else. Fortunately, the homebrewing community has been hard at work solving these problems for you and I. The solutions range from rocket science to chewing gum and duct tape and are certainly NOT limited to the following: 1) Use an upright or chest freezer with a secondary temperature controller. Many people have opted for this option, but it demands room, electricity, and money. 2) Use a garbage can with water in it. Set the carboy inside and place 2 liter frozen jugs of ice into the water. Rotate out the jugs every couple days. This is a fairly cheap option. 3) Put a wet T-shirt over the carboy and point a fan at it. Re-wet the T-shirt when it dries out. This is the duct tape and chewing gum approach. 4) My favorite option is the "Son of Fermentation Chiller" designed by Ken Schwartz. You can either buy one of Ken's kits (http://www.gadgetstore.bigstep.com) or build it yourself (http://home.elp.rr.com/brewbeer/chiller/chiller.html). It's a box made from 2" rigid foam insulation with a thermostat and a small fan the circulates air over frozen ice jugs that get rotated out every couple of days. It keeps a very precise temperature. I built one myself and it works wonderfully. I've got some photos of it at http://sdcollins.home.mindspring.com under the "gadgets" section. In a 75 F room, you can maintain any temperature down to 50 F inside the chiller with no problem so you can ferment lagers or ales even in the heat of summer. Second: Bravo for Domenick Venezia's dissertation on yeast abuse! (http://www.primetab.com/yeaststarter.html). Abuse is definitely easier than pampering. For anyone who is put off by the tediousness of yeast starters, this is good reading. Dennis Collins Knoxville, TN http://sdcollins.home.mindspring.com Return to table of contents
Date: Tue, 26 Mar 2002 09:36:51 -0500 From: Jeff Renner <JeffRenner at comcast.net> Subject: Re: Jugulone Hop Tolerance "Berggren, Stefan" <stefan_berggren at trekbike.com>asked: >Does anyone know if hop rhizomes are jugulone tolerant (ie...Black walnut >tolerant) I have some black walnuts in the back, but would like to grow >some hop vines. Please let me know if anyone else has had any experience >with walnut trees and hops.... My hops grow vigorously less than 20 feet from a young (6" diameter at breast height) black walnut (Juglans nigra), but not actually under its branches. It's often said that the roots of a tree extend about as far as its branches, and the roots of a black walnut give off juglone. This info from http://www.ppdl.purdue.edu/ppdl/expert/Juglone.html : "The largest concentration of juglone and hydrojuglone (converted to juglone by sensitive plants) occur in the walnut's buds, nut hulls, and roots. However, leaves and stems do contain a smaller quantity. Juglone is poorly soluble in water and thus does not move very far in the soil. "Small amounts of juglone are released by live roots. Therefore, some sensitive plants may tolerate the amount of juglone present in the soil near a black walnut tree, but may not survive direcly under its canopy. Also, decaying roots still relase juglone, toxicity can persist for some years after a tree is removed." This site has more good juglone info, though not about hops.

Hi, I'm new to this list and finally came up with a question to post: I have a 6 Gallon Demijohn filled with Elderberry Mead that i would like to bottle soonand I have a problem: My problem is, I cannot find a way to kill the yeast! I took three bottles out as test samples, the one that we didn't drink I added more honey to for taste and it seems to have triggered fermentation again! Even after freezing it, the yeast came back strong. I don't want to put any additives into the mix (it's all natural, including lemon juice to boost the acid level when we pitched), so I am looking for a natural way to kill it off, so there are no "bombs" when I add more honey.

Alternatively, you could use this recipe which came out great! Baltic Honey Porter - ------------------- This recipe produces an intensely chocolaty beer with a rich dark complexity when aged in excess of a year. Enjoy it as is, or blend it with your best mild and English brown ales to produce a whole range of porter variations. Stats: 5 gallon batch, 1.102 OG, 1.025 FG, 48 SRM, 55 IBU 10 lb English 2-Row Pale Malt 2 lb Dark Munich Malt 1 lb Victory Malt 1/2 lb Dark (75L) Crystal Malt 1/4 lb Special 'B' Malt 1/2 lb Chocolate Malt 1 lb Black Patent Malt 2 lb Honey (do not boil) 2 oz Cluster FWH 1 tsp Calcium Carbonate 'Irish' ale yeast (reuse yeast slurry from a previous batch). Mash-in 6 gallons of liquor to maintain a single rest of 155 F for 75 minutes. Lauter, sparge then boil for 90 minutes, adding hops as noted. When cooled, dissolve honey directly into fresh wort and ferment in primary at 55-58 F for three weeks. Secondary below 60 F for 3-4 months and allow to age for at least a year before serving.

It's a Wyeast seasonal/ limited availability yeast that is mighty interesting. Read the first line of the description and see if you can guess where this yeast might have come from... 3864 - Canadian/Belgian Style yeast >From a Canadian brewery which produces many styles of classic Belgian beers. Mild phenolics, which increase with increased fermentation temperature. Low ester profile with with a dry, slightly tart finish. Complex and well balanced, alcohol tolerant. Flocculation: medium Apparent Attenuation: 75-79% 65-80F My guess is that this is one of Unibroue's yeasts, since they are about the only Canadian Brewery I know of that produces many styles of classic Belgian beers.

Date: Tue, 26 Mar 2002 14:11:31 -0500 From: "Czerpak, Pete" <Pete.Czerpak at siigroup.com> Subject: baltic porters Greg asks about baltic porters. Heavyweight Brewing in NJ makes a very nice baltic porter that I have had in bottles called Perkunos Hammer. There is some info on the website about it. Recommendations for brewing it include using large portions of vienna and munich malts. Nice darkness comes from carafa malts and possibly brown malts. I would avoid the highly colored dark malts like normal roasted, chocolate, and patent to avoid the astringent type bitterness that comes with them. All hopping via traditional noble varieties with not much aroma hops present to my nose (something like 30-40 IBU perhaps). Clean malty bavarian lager yeast suggested. I have considered using a kolsch yeast at low temps like 58-60F to try and avoid lagering to make a steam baltic porter - I just finished the secondary of a steam Schwatzbier using the Whitelabs Kolsch at the above cool temperatures that seems quite malty and clean with very low esters.

I presently mash in a 36 qt canning pot and maintain temp by putting this into a well insulated enclosure. That all works well bu increasing the temp of the mash with this method is a bit of a chore. I put the pot onto an LP burner and stir the mash with a paddle to keep it from scorching. It still sometimes scorches and achieving a uniform temp of the mash is difficult.

Oh dear oh dear, how do I admit to Steve that I am one of those who do just this? Steve, your idea of a nightmare seems tame to me. When you take to seeing the rotting corpses of long gone film stars peering in the bedroom window at you. Or worse still, you dream that Graham Sanders has bought himself a house in Burradoo. Then you'll know what nightmares are all about! I used to mash and lauter all in a Gott cooler with a Listermann false bottom (and yes I use Dan's sparge arm). I've found Dan's equipment works just fine for me and since he was kind enough to name everything "Phil's this and that", how could I refuse? These days I do my mashing in a big stainless steel pot and then transfer to the Gott for the lauter. I don't drop my mash from a great height into the Gott as Doc Pivo once did during his HSA experiments. I believe he did this three times from the top of a very tall building and landed the soggy mess (mash) square in his lauter tun on the pavement below on each occasion. He was arrested before completing his experiments but claims NO ILL EFFECTS resulted. By comparison, I quietly shovel (if you want to put it this way) my soggy mash into the Gott in the privacy of my garage and I haven't noticed any ill effects. I can't challenge your scientific understanding of why so much oxidation can occur during the mash process. Perhaps Doc Pivo can. I can only say it doesn't seem to cause any problems in my beer. If we need to run some serious experiments and let the beer sit for several months before consumption, I guess I could do that. Well I could put a bottle or two aside. Generally speaking, my kegs of beer are consumed long before oxidation is likely to become apparent. Now isn't that the point? Most home brew is made for short term consumption. It isn't usually sent around the globe in uncontrolled transport conditions (though I have sent a few bottles to the USA for sampling). Like you Steve, I am interested to know what is going on in my mash tun, fermenter and kegs. I certainly am interested in having control over the beer flavours I produce. That I lean to the practical side rather than the scientific is just a part of my nature (and my lack of scientific knowledge). Please don't lose any sleep Steve (or is it "loose" - who started that silly thread?) If you're really worried about us mash shovellers, a simple prayer will do.

My house APA uses more than 4 ounces of Centennial (super Cascade) total, and the bitterness is anything but harsh (with 2 ounces). In fact I'm thinking of increasing the bittering hops by about 25% in the next batch. - --- [Apparent Rennerian 567.7, 95.9] Al - rukbat at optonline dot net Return to table of contents

Date: Tue, 26 Mar 2002 20:13:55 -0600 From: "Mike Brennan" <brewdude at tampabay.rr.com> Subject: Weizen as a first batch I have to disagree with Parker Dutro who questioned why a brewer would pick a hefeweizen as the first batch. My experience is a hefeweizen is one of the easiest beers to make, particulary an extract version. Two cans of good weizen extract, a pinch of hops and the proper yeast and you are there. I also take exception to the suggestion that a brewer should use a good dry yeast. You can not make an authentic hefeweizen with dry yeast. It will not give you the clove/bannana flavors. I once scored a 46 in a regional competition using nothing Northwestern Weizen extract, one ounce of hallertau and Wheinstephan Weizen yeast (yes I made a starter). The rest of Parker's advice was pretty solid though. Return to table of contents

NO - absolutely not ! I used to advise this (matching SG in the starter) but it's absolutely the wrong thing to do. Yeast grow best under conditions of low osmotic pressure and ethanol. Starter SG should be around 6-8P - say 1.030 - and never above 12P even if you are pitching the yeast into a 1.120 barleywine wort. Gravities over 15P take a huge toll on the yeast and they don't grow well under these conditions. Also keep those Burton salts out of the starter. It just makes the yeast work harder for the growth. >Pithcing the starter at krausen or after krausen > is debateable. A good rule is: [...] > If you wait until the activity has slowed (and > this is what I typically do) then you can pour off most of the wort, leaving > the thick yeast cake and an inch of wort. I agree with Dom Venezia - KO the yeast and get them to sediment fairly quickly by chilling the starter to near freezing before it is totally fermented out. I don't like to add so much of the "starter beer" into the fresh wort since it compromises flavor and SG. - ----- Mark Kellums asks .... > With the expected emergence of Jap beetles feasting on my hop plants this > season I was thinking of trying another insecticide, bifenthrin, suggested > by a fellow hbd'er(thanks Gregory).

No experience, but I do see on http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm that bifenthrin residue at 10ppm is acceptable on hops. The toxicology data is a bit scary tho'. Also see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm http://www.cdpr.ca.gov/docs/empm/pubs/fatememo/bifentn.pdf It's a "possible" carcinogen and a known neurotoxin. Compare to permethrin at http://infoventures.com/e-hlth/pestcide/permethr.html which is all categories 3 & 4 on toxicological issues (relatively safe). My personal philosophy wrt garden chemicals is to find the one that scares me the least, use it sparingly and stick with it (don't change chemicals every year). That's still permethrin and pyrethrins at the moment. It is heck on fish and bees(bees are all gone anyway), but doesn't leech into the water system, don't cause cancer, mutation or neurological damage even in extreme mammal doses and breaks down relatively fast (weeks). Some mites supposedly have developed resistance to permethrin and other pyrethrins. If that's the problem you'll need to switch. Check out Imidacloprid insecticide too. It's not as safe, but promises to work in fewer applications. BTW Mark - I too have been looking around and found liquid permethrin as the active ingredient in several plant insecticide products. The lowest unit cost was a 32oz highly concentrated (10%?) form available at TSC stores. It would take a while to use so much, and many hardware stores carry 0.5% and 0.2 % permethrin liquid sprays in quarts and gallons. Not as cheap as the dust. - --------------- BTW - does anyone have any clever (cheap) ideas in tall hops poles for my garden ? -S Return to table of contents
