I always say if I'm not mashing in by noon the brew day is canceled. Instead I'll spend a few hours doing as much prep as I can to get a jump start on brewing the next day and wake up early to get going. Fill the kettle, add the salts, crush the grain, even fill out my brew sheet and all that. Did this last weekend and even pre-heated the water overnight holding it at 130 with a block of pink foam in place of the lid to slow the heat losses. Only took a few minutes to warm it up to strike temp and I was brewing. Finished by noon and got even with myself for lollygagging.
