Ugh. Just finished a brew. Got started a little late and mashed in around 9pm. Just finished at 1:20am and I still need to clean up. At least I assembled my new grill during the down times.
I voted Afternoon but usually start a few things a day or two before. I generally brew on a weekend or a holiday so I'm not pressed for time. My "normal" brew day is midmorning to midafternoon, sometimes into the evening. But no set barriers.
I typically start in the morning. I usually try to get my strike water going by 9 am. But if I don't get going by 10 am, I usually don't get going at all.
my next one is going to be around 8pm. For some odd reason my friend wants to join in and he can only do it then. Normally I like to start right after lunch..
