Grain crush feedback

[grrickar]

You didn't see efficiency gains compared to what? Sparging of any type always increases efficiency compare to not sparging. Although in certain cases (like full volume mashing with bag squeezing in BIAB) the sparging gains in efficiency may be minimal.

Batch versus fly. I expect to see gains based on reading about fly sparging.

Are you unhappy with your efficiency? If your efficiency is down at 60% or below, there usually several actions you can take to improve it. If your efficiency is 80% or above, the amount of improvement you can achieve is more limited. There are people who can regularly achieve efficiencies of 85% - 90% and higher, but once you are at 80%, consistency batch to batch is more important than pushing efficiency. Of course, if you are OCD, and just want to get higher efficiency for the challenge of it, there's nothing inherently wrong with pursuing that, as long as the beer quality doesn't suffer.

Fly sparging doesn't automatically give you gains in efficiency. A well conducted batch sparge will give you higher efficiency than a poorly conducted fly sparge, and a well conducted fly sparge will give you better efficiency than a poorly conducted batch sparge. With either method, if your conversion efficiency is low, sparging still might not give the efficiency you are looking for.
