Did a parti gyle for the first time yesterday, splitting a batch (66% 2-row, 17% each white wheat and flaked wheat) 50/50 1st and 2nd runnings to make an IPA and a Berliner Weisse (12 gallons split to 6 and 6).
Everything went perfectly, including hitting all the numbers I was aiming for (1.052 gravity split to 1.067/1.034), except for one thing: I realized I had calculated all my numbers based off PBG rather than OG. So I guess I'm going to have closer to a DIPA and a slightly stronger berliner than I planned. At least the boil times on each of them are/were short.
The IPA is also my first attempt at doing a 0 IBU beer. I let it free drop to 190 after the boil, then pitched 3oz of mosaic and let it stand for 20 minutes before chilling. Doing several big drop hop additions of mosaic over the next week, including one today into active fermentation.
