This made me think. I use my noncontact IR theromometer for lots of things and it is pretty darn accurate. I'll have to try it on wort next time and compare to my floating one.
FWIW, I have a friend in the health department and he told me that tap water is fairly dirty if you don't take precautions. What is in the lines is fine but our taps get wet and dry and harbor lots of bacteria, especially in the aerator. He suggests letting the water run for at least 1-3 minutes...
It varies. I bottle a few in PET bottles for testing over time, but have found 3-5 months is about right. The batch I bottled in March, people I gave it to loved it and want more.
I ran into that, so I made her a batch of wine. She enjoys it and loves passing out bottles to her friends. So twice a year I'll make a batch of wine and no problems, because all the new equipment can be used in the winery, or so I claim. :D
I started with a Mr. Beer that the wife got me one year for Xmas. It is functional and produces a drinkable beer, some of their recipes are even quite good. But you get small batches. The following year the wife bought me a 5 gal. setup and we haven't looked back. You can also use the 5 gal. rig...
I thought this was interesting...
ALBANY, N.Y. - A line of taps pouring elegant brews from Bass to Blue Moon beckon twentysomethings packed into Bomber's bar. But 21-year-old Elliot Cunniff orders something homier for himself and a friend.
``Two Yuenglings,'' he tells the bartender...
If it was pure acetone it should work and be residue free. Any scratches inside, if so pass on it. But I would spend a few bucks for a food grade bucket.
FWIW, I have 2 coils, one goes in an ice/saltwater bath and the second in the wort. For maximum heat transfer you want to find the sweet spot in the flow rate that transfers the maximum heat. Heat exchangers are magic beasts that require a black candle, a knife and a goat to get dialed in just...
For the chiller, it is difficult to bend the copper without kinking it. Fill it with sand first and that makes it a bit easier to bend a radius without kinking. Use a form to wrap it around. I use 1/4" myself, it bends easier and works quite well, but I would not go over 3/8" as it gets unweildy...
I always put the primary in front of the cold air return for the central A/C which tends to produce a nice breeze and keeps the coolest air in the house flowing over it. I has slowed down somewhat but is still banging away, should be ready for secondary by Thursday I suspect.
The state is actually the least of your concerns. You do not want to get crossways to ATF. If you sell homebrew you are no different than a moonshiner in their eyes, with all the attributes that come with that distinction.
The wife bought me a set of 16 oz mugs a couple months ago. They live in the freezer and come out when I want a cold home brew, which is every night. :D
