So I did my first all grain brew today using the beer in a bag method. I mashed with 4 gallons in my cooler with 11 pounds of grain in a jumbo grain bag. I hit my temperature of 155 initially but within about 10 minutes it had dropped to about 150, where it remained for the rest of the hour. Not too bad I hope...
Then I batch sparged with 190 ish water...about another 4 gallons. Then strained the whole lot through another mesh bag.
Did my boil...4 different hop additions in a hop bag, Irish moss. All good. Then put the chiller in and brought her down to 75. Almost to temp, the tube popped off my chiller and dumped unsanitized tap water into my beer that I just spent hours mashing and boiling.
Now we have a pretty substantial water treatment system here at our house involving a water softener and additions of chlorine and some sort of acid. So I'm hoping no infection will result. But the lesson here is USE CLAMPS ON YOUR CHILLER!
The other thing I wanted to ask was if I was computing my brewhouse efficiency correctly. Here's what I did:
11 lbs of grain X 36/5 gallons into the fermenter =79.2
OG was 1.052 (1 point off of my anticipated OG according to the beer recipator). So then I did 52/79.2 to get 65.6566% brewhouse efficiency. Is that right?
