Did 3 single batches yesterday. Boil one, mash another, no chill the middle one.
A long day, a bit like work in some spots and you find your concentration waning on simple matters like 'does that alarm mean 20 minute hop addition or mash-out time?
Nonetheless, they all came out ok with rough efficiencies and volumes being met.
All single infusion, batch sparged.

Ran out of gas during the third boil but few other dramas apart from that. I might stick to 2 batches per day in future but at least I know it can be done. I have new boil pots now - I used to do a batch in two boils/chills with a 10 L and 15 litre pot which took the better part of a day just for 1 so I was pretty stoked.
