...or why im adding a grain mill to my Christmas list.
Picture says it all. Left is MoreBeer, right is Northern Brewer:
I had the grain on the left as leftovers from my last batch. I had been using MoreBeer for about 6 months and just before I started all-grain brewing. I was shocked at how the crush was so much finer on the Northern Brewer grain.
10min into the mash right now. Will be interested to see if my efficency goes up (have been steadily getting in the mid-60s for all-in efficiency).
