Til it's dry, I guess. Hopefully 2-3 weeks. I know I should've left them flat because then I'd be guaranteed it would dry without problem, but I just had to roll them. Did my best to get a very tight roll, the idiot who butchered them (me) didn't trim the belly very well. Fingers crossed. Need to rig something up with welded wire to keep the critters out, too.
The only thing worse than dumping beer is serving beer you should have dumped.
