I'm responding primarily to watch the panic.
I should also note that the vast majority of my ale ferments are over within 72 hours of pitching. That's with proper pitching technique, of course, but consider that an 11g sachet of dry yeast is in most circumstances good cell count.
I've packaged after seven days in primary with no issues. My
Mild - which leans strongly on Uncle Charlie's
Cheeks to the Wind - often gets packaged after seven days; 48 hours, the ferment is done, 4-5 days after that, it's star-bright and ready for packaging. Tastes just as good as if I leave it sit for weeks. [shrug] YMMV.
In this instance, if they used the sachet in the lid of the tinned kit only, I'd say don some safety glasses. But since they knocked in
another sachet of yeast, it
better be done fermenting, or there's something
really put of whack.
One thing you really need to do is
, though.
Cheers,
Bob
