That’s so cool, thank you!!
The big dial turn to turn is the Carafa II. If you like a lot of roast, eliminate it and give those ounces to the Roasted Barley. If you like to keep the roast to a minimum, go the other direction. The % that you see there is my preference, but everyone’s mileage definitely varies. The wheat, I have found, is responsible for a nice sustainable head. My one, absolute must have is BRY-97. I have tried Stouts with various other yeasts, but this one works best for what I was going after...dry and sessionable. If I was making an Oatmeal Stout or a Milk Stout, I would choose a different yeast.
If you ever brew this, please let me know how it comes out!
