YEAST
Wyeast 1056 – American Ale
Made a two-stage starter on a stirplate a few days before.

FERMENTATION
3 Weeks @ 17.5 C (63.5 F)

NOTES
Needed a blow off tube for the first week+ of the fermentation. Blew off a lot of yeast. Had in ambient of 17.5 C (63.5F) for the first week and them let it rise a degree or two. Once ferment calmed a bit I replaced the blow woof tube with an airlock. Fermented for another week or so with bubbles in the airlock and movement the carboy. Kegged at near four weeks. Wanted it for the weekend so I put it at about 1 C (33F) and at 32 psi for 48 hours – had good carbonation – removed headspace pressure and put 10 psi for serving.
