Is it possible for gravity to drop from 1039 to 1010 in 4 days?

Hi all, is the gravity dropping too fast ? The kit does say fermentation should be finished in 6 days. It's coopers lager kit

It's not only possible, but fairly likely, depending on fermentation temperatures and an adequate yeast pitch.

I routinely have brews that go from 70-75 points down to 18-20 points in under 72 hours, and hit terminal gravity by 5 days.
As long as you keep the wort temperature within the yeasts' neutral range the rate of SG drop is probably not an issue....

Cheers!

That's perfectly normal.

Don't be worried, be proud! It sounds like you did a great job setting your yeast up for success. Great job!

 

[odie]

well we need to know OG, type yeast, ferm temps, etc...

But I've seen beers finish in barely a few days. It is possible.

 

[Calder]

Yes, that drop in that time is normal.

yes
