I brew with extract, and 5 gallon boils.
In the last batch I brewed, I added 1 lb of biscuit malt to the suggested steeped specialty grains. All the grains were steeped in the full 5 gallon volume.
The OG came out to exactly what the base recipe suggested. I had expected it to be higher because I had added a lot of steeping grains that the recipe did not call for.
Why wasn't there starch to sugar conversion from the extra pound of grain? Or, in a 5-gallon steep, is the solution too dilute to allow the enzymes to get to work?
