Thanks. When I plug that in to ProMash, I get an extract of 1.038. However, that doesn't jive with a formula I got from another forum:
SG = (DBCG - MC - .002) * 46.214
For a fine grind of 83 with a difference of 1.65, that would give me the following:
((.83 - .0165) - .04 - .002) * 46.214 = 35.65 or 1.036
Am I missing a variable? Which formula is more accurate?
