Trois IPA

So this is the 3rd iteration of the Brett IPA I first brewed in August of 2014 using WLP 644. Since then, those rascally microbiologists have discovered that WLP 644 is not in fact a type of brettanomyces but rather "Saccharomyces 'bruxellensis' Trois". Regardless, the last two brews of this beer were some of my best IPAs, so I've decided to brew it again, this time with a full 5-gallon batch, and, continuing the slight tweaks, using Lemondrop Hops instead of Cascade.

Notes:
After flame out and addition of Whirlpool hops, recirculate using March pump, allowing to whirlpool for 5 minutes at ~210F. Then cool to 180F and allow to whirlpool at 180F - 160F for 30 minutes. Apply gentle heat if needed to prevent it sinking too fast to 160F.
------

2/10/16 - Made starter with 60g of DME, 1100 ml water, yeast nutrients and a little bit of leftover Citra hops.
2/13/16 - Brewed. Hit my mash temps well. For some reason I got lower gravity than expected. Pre-boil was ~1.044, Post-boil ~1.054. Probably a bit over volume. Need to adjust my equipment profile in Beersmith for about 0.5 gallon of dead-space in my big MLT. Otherwise brew-day went fine. Also it was VERY cold (~10F) so maybe that messed up my refractometer.
After whirlpool and cooling, racked to 6 gallon fermenter, leaving most of the hop gunk. Wort at ~90F. Set in 65F ambient to cool. Pitched most of the starter a few hours later after oxygenating for 20 seconds. With starter, 5.5 gallons in fermenter.
2/14/16, 2pm. Good krausen going. 

2/15/16, 5pm. Very active fermentation. Constant airlock bubbling.

2/20/16, added dry hops directly into primary vessel. Fermentation appeared complete. Moved vessel to 70F ambient.

2/27/16, crash cooled. Will keg tomorrow.
