I'm trying to figure efficiency by backing into the numbers, but I can't figure out how to (or if?) I need to adjust somehow for lactose addition in the boil.
I'm using BrewMate software, which tells me the OG on a Left Hand Milk Stout Clone should be 1.060 for a 5 gallon batch, assuming 75% efficiency. However, it has you add lactose in a miscellaneous spot with no potential gravity input. I've seen a couple of adjustments on the forums here - from .004 to .009 points - for 1 pound of lactose added in to the boil. Can anyone confirm the appropriate number?
Going into the fermenter, the adjusted gravity reading was 1.063, including the lactose.
