A few days ago I did my first partial mash. The grain bill was:
3 lb. Maris Otter
1 lb. Flaked Oats
.5 lb. Pale Chocolate
.5 lb. Roasted Barley
.25 lb. Flaked Barley
.25 lb. Crystal 60L
.25 lb. Crystal 40L
I used 1.5 quarts of water per pound of grain and hit my temp of 155. After half an hour it was dropping below 150 so I added a quart of boiling water to bring it up. A half hour later I drained it and sparged with water around 170. I collected 3.25 gallons which is as much as my pot can hold. I got a SG of 1.057. Added a 3.3 lb. can of liquid extract, boiled, cooled, added to fermenter and topped up to 5 gallons. I got a SG of 1.041, quite a bit lower than the estimate of 1.054. I knew one of the readings had to be wrong so the next day I took another one since there weren't any signs of fermentation yet, and got the same thing. I added 1.5 lb. of dry extract to get it to where I want, but this means that the SG of the 3.25 gallons that I collected was probably around 1.027 which would put my efficiency at something like 45%. How can I get better efficiency?
