There wasn't too much trouble with grain. 22 lbs in the Gott. 15 gallons in the kettle was a bit scary. I did use a defoamer, but I did have a small boilover with the first hop addition. I boiled for 90 minutes. Final output to two fermenters was a total of 11 gallons of 1.050 wort. With losses in racking I should get two full 5 gallon kegs.
