I actually have a checklist (I'm obsessive like that). First thing is first, I open a beer. With 50 mins left I grab the other stuff I will need (aerator, carboy, utensils etc) and sanitize them. 35 left I pull my hops out of the fridge and weigh them out. Grab another beer...Measure out my sparge water and by 25 mins left that is on the burner. Quick peek at the temp probe on the mash tun to make sure nothing went horribly wrong, grab the pitcher for vorlauf and refractometer for first running gravity. Set up the bench that I place the boil kettle on for the runnings. With 10 mins left I pace back and forth nervously and check the clock every 30 seconds until it's showtime.
