I used to use thier grinder but I found that my efficiency was not consistent. I bought my own mill and this cleared that right up. As for thier malt, I don't know if I love Cargill, or Shreier, which is what they used to carry. They always seem to have all the hard to find hops in both leaf and pellets. I see Citra, Simcoe and Amarillo there on a consistent basis.
