Using US-05 as the yeast type.
Per Jamil Z's book Brewing Great Beers, Use American for a drier / roastier version and an English for fruitier.
On this recipe I'm calculating at equipment setting of 1.5 gallons of dead space in keg. Seems 2 gallons as a figure also resulted in higher yield going into fermenter, I believe other figures were correct, so adjusting this. (once I though 3 gallons, I believe grain in keg effects my measurement.
original recipe was based on calculation at 70% efficiency.
Target OG: 1.064
Actual measurements: 1.046 pre boil grav.
Actual orig grav: 1.056 orig gravity<br />
Actual final grav: 1.011<br />
volume was just about on target with approx 5.5 gallons in fermenter. (its a bit hard to tell for sure).
If all else stays consistent that would put my final efficiency at 60% (research how to increase)
