I have vigerous fermentation for 3 days very hard ferment and now at day 6 no airlock activity at all
was about a 7% beer do you think it would be done its fermentation ?

[Shawn]

It's probably done, but until you get a hydrometer, you won't know for sure.

[Kyle]

if it was warm or you racked onto a yeast cake, this is not surprising at all.

[Richard]

I agree with both Kyle & Shawn - it's almost certainly done, but you'd need to do a couple of concurrent days' SG readings to know with any certainty. Another caveat would be to make sure that the temperature drop lately didn't put the yeast to sleep - but as long as it's above 16C the SG readings are more than enough.

yea fermented at about 72 and then dropped to 65
