You're going to need more hops, then. You can probably make a decent 3 gallon batch, but any larger, and more hops and grain are in order.
I was planning a five gallon batch. What is a typical amount of grain for BIAB? I could purchase additional grains or extract- no problem. I guess I'm just wondering if any of this stuff would go well together.
I was thinking of using the Gambrinus, Crystal and Roasted Barley. I was planning to use all of the hops! I figured I'd use the higher alpha varieties earlier and end with the lower types.
