So I brewed my first AG batch today, a Kolsch. Assuming 65% efficiency I calculated all my volumes and weights. In the end, I only achieved 55% or so, but since I also boiled off more than I expected to, I ended up with a specific gravity within 1 point of what I was aiming for.
How can I get my efficiency up?
I mashed 10.3 lbs at 148 (struck at 160) for 60 minutes at 1.5 quarts/lb. Then I sparged with 4.8 gallons at 170F. I lost about 1.5 gallons due to absorption (about 2/3 of that) and system (1/3). I'm using a 10 gallon cooler with a false bottom.
A friend of mine has the same set up and I saw him get 60% his first mash. What am I missing?
