Hey Alan, Long time fan of the Aeropress here. It's a life saver. I always take it with me on deployments and normally end up having to make coffee for the other guys after they give it a try. Just discovered your cold brew method. What kind of roast do you recommend for the cold brewing method i.e. light, medium, dark . . . .? – From John H.

I prefer medium roast. Light roasts tend towards sour. Dark roasts tend towards bitter.
