I just brewed a porter using a partial mash. BeerSmith tells me the OG should be 1.050 (assuming 75% efficiency), but I got a reading of 1.042 meaning my efficiency was a dismal 50%. What can be done to improve efficiency, or should I just expect this in future brews and compensate with more grain? I'm batch sparging, and I did a 60 minute rest at 154 degrees. The initial strike water was added at a ratio of 1.25 quarts per pound, and I used 5 lbs of grain. I did have to add an extra pint of boiling water at the beginning to get the temp up to 154 from 150, which I tried to quickly stir in.
