I’m a batch sparger. When brewing kits from NB, I typically meet or exceed the OG by a bit.
Now, I’d like to brew the Oatmeal Cookie Brown recipe kit. It only comes in a 3-gallon BIAB version, but I’ll be brewing it with my batch-sparge setup.
Here’s my concern, and my question: Does NB count on a different mash efficiency when formulating BIAB recipes? If, for example, NB assumes 75% efficiency when formulating their AG recipes and 65% efficiency for BIAB recipes, then I might end up with a substantially higher OG than intended.
