Call your nearest tractor/farm supply. It's not going to be "food grade" or "USP grade" (then, neither is RV antifreeze). It is used to prevent ketosis in cattle/goats.

I would agree -- it's not going to be considered 'flowable' through 1/16 or 1/8th lines. 1/2" lines though, with higher pressures from a much more powerful pump, and the fact that it only needs to move far enough to be heated -- well, that's why we don't buy new engines/cars every spring...

Good thought on the specific gravity, and you might be right on the freezer temp -- most start 0F and go down from there, but probably not -55F. All that said -- your original post mentioned that it froze solid but here you say slushed? I ask because the issue could be that your pump is a...

LOL. Propylene Glycol is in many foods, including flavor extracts and is used to thin medicines that can't be cut with water. It is NOT poisonous. OP: look for food grade or USP(pharmaceutical) grade PG. You can find it on amazon by the quart or gallon. I should add that I would only...

I agree with others that you may not have mixed it. A mixture of 40% water/ 60% glycol is required to achieve -55F freezing temps. This works because the glycol prevents the bonding of the hydrogen structures in water, hence the reason the mixture is required. BTW: Propylene glycol (100%)...

I would normally agree -- however, it would be important to me that the information is listed under a Creative Commons (or similar) license that seeks to keep the information free -- redistribution and attributed use like Wikipedia (and the two projects listed) is a good example. Also, HBT...

So I have an idea that I would like to share and, hopefully, get feedback from you fine people (you miscreants can share too). Feel free to skip ahead. Intro of sorts: For quite some time I've been interested in brewing, obviously, and have a few brews under my belt. By no means could I be...

Could you write it off? Probably. Would I? Definitely not. I wouldn't be as concerned with the IRS rejecting this "business expense" as I would the fines from city/state government for the production of beer without a license. Here's the difference as I see it: If you are buying the...
