I would wait until it stops bubbling or slows down. If it's still working then there's still sugar in the wash that the yeast is still eating. Don't be in any hurry and let it work.

Hi Ikammer, if it's not finished working leave it alone and don't open it. Once it stops working it will need a couple of days to settle and then rack it off the solids, traub, and let it settle out another day or more. Sounds like your next day off should be about right.

Traub is the solids at the bottom of the fermenter, grains, yeast, and anything else that is solid. You don't want to leave your beer sitting on it any longer than it has to for fermentation. It can cause off flavors to develop if left to long. When your beer is siphoned into another container to settle the rest of the yeast will settle out, mostly. Does'nt have to be completely clear, like water, before you run, but as translucent as it will get is best.

Like Bushy said It can sit for a while no problems. sometimes mine will work for up to a month then i'll rack it off into another bucket and let it sit another week or two. It wont be clear as water but it will be smell strong like wine and there won't be any solids in it. Be patient.
