Purchased this a few months ago and love it! However, I have been getting some pretty low efficiency on my last few batches (less than 60%). I don't have a mill, so I usually just have my LHBS crush for me at their standard crush setting. I'm assuming this is where my efficiency loss is coming from. Can anyone recommend what they crush their grains at using the anvil foundry to get good efficiency without having to deal with stuck mash? I'd like to try experimenting with a different size crush to see if that boosts my efficiency up. Ideally if I can stay in the 70% ^ range I'd be happy with that.
