I have heard that if your efficiency is too high you'll pull out tannins and that you never want to hit 100% efficiency. Is that true?
I have a series of questions and if they have all been answered before I apologize in advance.
First the set up: This is my third all grain brew. The first two had very low efficiencies 50's and 60's. I came to the conclusion that my crush was off so this time I cranked the grain mill way down. To add to that the recipe I was brewing called for a 90 min mash. I mashed a little higher than the target (154 degrees instead of 152). When I went to go batch sparge I got a phone call during my second sparge and I was tied up for about 20 minutes. So the second sparge sat at about 152 degrees for about 20 minutes.
I pulled 14 gallons. Split them into two kettles and boiled them down t 12 gallons.
The efficiency going in the boiler was 95%. The efficiency going into my fermentor was 99%.
My math may be a little off because I used flaked maize and minute rice and I am not 100% that I used the correct numbers for the minute rice.
Am I in trouble for getting off flavors? Should I worry? Which efficiency matters into boiler or into fermentor?
