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...
This would be for each 5 gallons treated right? So if I want to treat 10 gallons at once for an english pale I'd add a grand total of 4 tsp calcium chloride and 2 tsp gypsum?
