And at the end of a busy brewday, what do you get? In this case, two half-barrel fermenters full of Interstellar Pale ale, just needing couple weeks of fermentation, thus the air lock. Very educational day for me; learned to smash a yeast pack, what a hop-spider is and how to connect the pump for a sparge of the mash. A tiring and satisfying day, to be sure. I'll let everyone know when the keg(s) are tapped. Upstate Craft Beer Co.
