I have left washes for up to 7 days unattended with no problems. Back
thanksgiving week I had a wash that was about half finished and had to
leave for a week. I simply put the top on the bucket with an air lock
and left it. It was just fine when I got back and it was another 3 or
4 days before it made it to the still. Turned out pretty good
actually. Probably because of the long settling time. Just for
reference it was a wheat germ sugar wash (10 lbs). I do not normally
like the use of air locks but this is a case as is your where I would
recommend the use of one. It will also help keep the smell down if
you have nosy neighbors.
Damn its been a busy week.
Missed you guys.
