How Long is Too Long?

[rsa]

My 6gal juice of Sangiovese is still fermenting for over a month. Here's the particulars:

10/8 Started with Lalvin 212 SG 1080
10/13 SG 1025
10/20 SG 1012 Racked to carboy
10/28 SG 1002
Vacation
11/12 SG 998

Temperature steady at 70 degrees

Granted the activity has slowed way down, nevertheless it's still going.

How long can this go for?

Are you sure it's not just degassing?

Keep checking the SG. Once it goes three days without changing, then you know it's done.

Maybe that's it. I'll keep checking SG then degass.
