I'm a very new brewer and I need some help. I have only done kits so far, but I want to Make Orfy's Mild Mannered Ale. The problem I'm having is with conversions. Orfy says to use 4.89Lbs of Light LME. My LHBS has them in 3.3Lb containers, so I thought, Okay, I'll get one of them and some more DME. I believe I should be using 2Lbs of DME and the 3.3Lbs of LME to get to an equivalent of 4.9 LME. Is that correct? Thanks!
