When I brew, 90% of the time it's in the evenings, with the bulk of it after i put the kids to bed. I try to weigh and mill grains the day before, as well as weigh out hops, then number the zip locks i put the hops into according to their hop addition. I can do all that in the living room with kids running around. it only takes them one bite on a magnum hop pellet to leave me alone to my thing.
My average schedule:
~7:30pm - setup burner, BK, add water to BK, fire it up
~8:15pm - add strike water to mash tun, then get one of the kids to stir while i add grains (they argue about who gets to stir, and I let them)
~9:15pm - stir up the mash tun, vorlauf, and collect first runnings. Fire up burner while collecting runnings
~9:30pm - batch sparge (and vorlauf), collect rest of wort
~10:00pm - usually starts to boil. While the boil is going on, I clean up the mash tun, dump the spent grains in a bucket to give to farmer for feed, sanitize fermenter and hose to drain to fermenter, clean up other things if necessary. I don't usually crack a beer until the boil is well under way.
~11:00pm - chill wort (IC).
~11:30pm - fill up fermenters with liquid gold, aerate while filling it up, pitch yeast.
~12:00am - scrub brew kettle and clean up.
~12:15am - go to bed.
About 5 hours for a 10 gallon batch. shave off about 30 minutes for a 5 gallon batch.
