Full disclosure, in my haste of ordering ingredients for an upcoming brew I picked up a kit recipe, Palmer Premium Beer Kits - Harold is Weizen - Hefeweizen, not realizing it was an extract recipe. Not wanting to discard the kit and waste more money I dug around looking for posts that might shed some insight on what to do if you wanted to plan an extract brew using BIABacus. I did find one that mentioned changing the Kettle to Fermenter Losses (KFL) in Section X. to 0. Although I don't agree that there will be zero, it will likely be very minimal given that DME dissolves completely and this recipe only uses 1 oz/28.35g of hops (Hallertau). Having done this Biabacus tells me that I need 5.56 pounds/2.52 Kg of DME. The kit comes with 6 lbs/2.72 kg of Briess Wheat DME. Not a huge difference and I often find that when I brew recipes from Brewing Classic Styles, where this recipe comes from, I often achieve higher O.G. when using what they call for and have learned to adjust for this. I'm also assuming rather than using Total Water Needed (TWN) I'll add the Volume Into the Boil (VIB) minus probably a half gallon or so to account for what the DME will displace. So my question is, what am I missing for values that need to be changed in the defaults to get this recipe right having never brewed this one before? I have attached the Biabacus file below. As a sort of side note, you'll notice I split the DME in the substitution column to ensure that Biabacus adjusted things correctly and annotated that the DME would be a boil addition only.
