Although I don't use all of my spent grains this way, I have used them as bedding in a bait box for nightcrawlers when going fishing. Only problem is that you can't keep it very long before it gets mouldy. Jerry Zeidler Williamsport, PA Return to table of contents

I probably have the recipe around here somewhere but since it was posted on HBD some years ago it may be in the archives. If you have a cow, horse, goat or sheep, the spent grains can, and often is, fed to livestock. A number brewpubs and micros provide their spent grains to farmers. Without livestock, and one can eat only so many muffins, alas the spent grains now go into my compose bin. I'm glad that Dave reminded me that there had been a recipe for dog biscuits made from the grains. Now that I have a dog, this is a must. My wife is excited to make the biscuits. A two-fer!!

Where the 1/2" copper pipe passes through the wall of the cooler to mate up with the ball valve, it's snug....but as I'm concerned about some leakage I'd like to seal that area with something. I've managed to find some "aquarium safe" silicone, but there's no mention of FDA. I'm guessing if it's good enough for fish, it's safe enough for me. Does anyone have any expertise on this subject?

Its about 50% phosphoric >acid, and 50% surfactants, dyes, and other. I use milk stone remover periodically to clean my boiling vessel and kegs. I use about 20 cc and a gallon of water to clean my boiling vessel. You can wipe the beer stone out immediately. To CIP my kegs I use 20 cc, 5 gallons of water and soak overnight.

Date: Sat, 6 Sep 2003 15:38:24 -0700 (PDT) From: Eric Starkey <ericox at yahoo.com> Subject: Sparging Help First off, I am farily new at brewing. I have read books and various posts but I still have some questions on sparging. The system I am using is 2 five gallon buckets, the first having the bottom drilled to resemble a false bottom and the second bucket having a spigot for draining (the first bucket setting inside of the second). My questions start here. How exactly am I supposed to sparge the grains. Do I recirclulate the grain tea through the grains? Do I separate the grains, then sparge them with the clean sparge water and then add this back to the tea? If someone out there could walk me through this process I would greatly appreciate it. Many thanks and happy brewing. Eric Starkey San Jose, ca Return to table of contents
Date: Sun, 7 Sep 2003 07:58:05 -0500 From: Clayton Carter <crcarter at cs.indiana.edu> Subject: First Post / Stuck Fermentation / `Safe' SG Hi All, This is my first post to the list, which I've found immensely helpful (if a bit overwhelming sometimes). Anyway, I'm in the Boston area and my second batch is just winding up fermentation. My first was a True Brew pale ale kit it was really, REALLY good. This time I've made a brown ale that the brewshop had on record as `Down South Brown Ale'. I've had a really good time with both batchs and I think that I'm going to upgrade to glass for my next batch. What I've found so impressive about homebrewing is that, no matter how specific and technical the directions get about being sure to do this or that, so long as everything's clean, it's really hard to screw up the beer. I used tap water in the first batch and fermented it around 83F and it worked fine. I did the same this time, but I also had the top blow off the bucket (I guess I hadn't attached it as tightly as I'd thought) during the night and had krausen all over the table. I tasted it last night and it seems to be coming along nicely. Anyway, my point is that I'm wondering if this batch is stuck at the very end of the fermentation. I don't think it is, but I thought I'd ask. I brewed and pitched on Wednesday and the airlock was bubbling within an hour. Like I said, the top blew that night, but I did some minor cleaning and replaced the lid to see that the airlock was still going quite vigorously (1-2 bubbles / second). I'm not worried about infection from this since I figure that there was a good layer of foam on top to block any nasties initially, but also becasue the yeast was outgassing so much that not too much air had a chance to get in. ANYWAY, bubbling has stopped now, and it's been very sluggish for the few days leading up to yesterday. Last night, I sanitized a glass, popped the top and took an SG reading of around 1.025. Big deal, right? I thing the OG was around 1.058 or 60. The recipe doesn't give OG or FG, but it does explicitly say -- and this is what gives me pause -- that the beer isn't safe to bottle until the SG is below 1.020. My common sense says to go ahead and bottle, but I thought I'd ask you folks. I'm about 95% certain that fermentation really has completed, but that stinking line in the recipe about the 1.020 figure has me worried. Thanks so much.

Date: Sun, 7 Sep 2003 10:15:52 -0400 From: "-S" <-s at adelphia.net> Subject: Re: bitterness from decoction Marc Sedam notes, > [...] why a decocted > beer might be less bitter and I had a thought. I think there is > agreement that decocting a beer puts more tannins in the wort INITIALLY. > But these tannins get bound with other proteins in the wort and settle > out during the lagering process so that the final amount of tannins is > not presumptively different than in a non-decocted beer. > > Could the alpha acids be precipitating out with the protein-tannin > complex in the decocted beer?[...] This conjecture correlates with a note in M&BS that decocted wort contains more oxidizable and less oxidized polyphenols then infusion wort. Oxidized polyphenols are more likely to bind and end up in the break; oxidizable polyphenols are largely anti-oxidants - waiting to become oxidized then bind. The boil nearly clears he wort of oxidized polyphenols. Same for the decoction boil. . The factoids that I am not certain about is ... does post boil decoction wort really contain more tannins(tannoids) than infusion wort ? I *suspect* this is true. Then there is the question - does lagering sediment significantly trap humulones or other bitter principles ? Lagering certainly makes the beer smoother and (my guess) less harshly phenolic. I also have some doubts about the idea that decocted beers generally have reduced bitterness for a given hopping schedule. What does the collective think ? Is everyone seeing that it requires more hops to achieve a given IBU level in a decocted beer ? Obviously the lagering and general style considerations mean that lagered beers usually lack the full aromatics of hops and the very high IBUs of many ales. The principles of controlling hoppiness and bitterness are obvious, but in practice all the rules and detailed hopping formulae are nearly useless since minor variations in the strength of the boil, and the freshness of the hops will swamp any calculation. I suspect that getting beer IBUs w/in 10% of target is an achievement. Last year, after moving, I made a series of beers where each was a notch more bitter than expected. I started to suspect my new water supply or some other factor in my HBrewery was to blame. Then just as suddenly the problem ceased. Perhaps a couple bags of hops were fresher then usual of my nat.gas burner pressure a bit higher. Hops can lose 10% of their humulones (not total bitterness ) in a month of mediocre storage! Good thought Marc, -Steve Would somebody PULEEZE add an address mangler to HBD. I now get 75% spam on this HBD-only address. Return to table of contents
Date: Sun, 7 Sep 2003 07:28:46 -0700 From: Jonathan Royce <jonathan at woodburybrewingco.com> Subject: RE: Why prime with DME? Joe Berardino asked about why one would prime with DME over corn sugar. First, I will note that this post is being written while wearing my flame- retardant suit, so I'm prepared. Anyway, my answers is: I can't think of any good reason. I primed a batch of cream ale earlier this year with DME and the results were unimpressive. I believe Papazian mentions somewhere that (anecdotally) DME produces finer bubbles than corn sugar, but in my case it produced no bubbles at all. The entire batch was undercarbonated and while the flavor of the beer was great, I fizz. (It was basically flat). I also ended up with a lot of sediment in every bottle, which I also suspect is due to DME. In all fairness, the carbonation probably would have been okay, had I chosen to use WEIGHT rather than VOLUME as the method of measuring the priming medium. That said, my advice (other than using corn sugar and restricting DME to wort) is to forget the 1 1/4 cup measurement recommended by your book and to use HBD's recipator to calculate a weight of DME to use for priming. This would likely produce much better results. http://hbd.org/recipator Hope that helps and (as always) happy brewing, Jonathan Woodbury Brewing Co. www.woodburybrewingco.com Return to table of contents
Date: Sun, 07 Sep 2003 17:24:54 -0400 From: NO Spam <nospam at brewbyyou.net> Subject: Re: Spent Grains Perfect timing on this one, I was about to post the same question. How do the rest of you city guys get rid of this stuff??? I've found that even if I put the grains in a plastic garbage bag, put that inside of another plastic garbage bag, put that in a paper bag, then put that inside another plastic garbage bag, this stuff still leaks all over the place, right through the bags. I have no idea how. It makes a mess. Now I live in a development where we have an association and rules, and you can't just leave trash out anywhere or any time. And I wouldn't with this stuff, anyhow. It leaks all over, and the stuff stains concrete! I don't want to hold this in my garage again, I already have a huge stain on the concrete floor from the last batch. I've scrubbed it hard, and alot of it won't come up. And keeping it in the garage for up to week, (my garage is not air- conditioned, I don't know about yours) well, let's say it doesn't smell great, either. I have tried the garbage disposal before, but 10 lbs or more of grain is alot for that to handle. It puts alot of stress on the motor. Mine kicked off 2 or 3 times during the grinding, and had to be reset each time. I'm afraid to try that again, because I'm afraid that one of these times, it won't come back on. And that would s**k if it happened with a drain full of spent grain! I have been setting it out in the grass until trash day, but I'm not going not get away with that for long. I'm just waiting for someone from the association to complain. During the summer, I imagine it would be great compost for the garden. But during the winter? I don't know. What's the best way to store spent grain til trash day without having it leak all over and stain and stink up everything? Or is there an even better way to get rid of it? I'm not going to drive it and leave it on someone else's property, either. That's just wrong. Bill Return to table of contents

I was wondering if someone could point me in the direction of the article because I could swear I had it but I can't find it. If anyone has any tips as far as fabricating tap handles please let me know. I woule like to print some graphics up for my beers and then put them into the tap handle ManyThanks, Eric Tepe Return to table of contents
Date: Sun, 7 Sep 2003 18:43:46 -0700 From: "Scott" <sejose at pacbell.net> Subject: Help with Temp Control Hi I've been using an old electric blanket and a Johnson controller on my ferment fridge to control temperature accurately. But now I have a couple waterbed heaters which would be better than the old blanket, except for one small thing. This is where I need help. The controller for the waterbed heater starts at 70 degrees F and goes to 100. I need to modify the guts so that the controller will work from say 50 or 60 (or whatever I need) instead of the 70 degrees. I am not familiar with electronics such as are inside this controller, but if someone smarter than me can help me, I can figure it out. Can it be as simple as installing a resistor (or something) inline somewhere to affect this shift of temp control? Thanks for any input and help. Never too old to learn a new trick....
