F.G. fermentation ?

[BeehiveBrewer]

I brewed a 'Brooklyn Brown' . It has been in the primary for 13 days.

My OG was 1.065 and I took my first sample reading tonight. It was 1.038.

That seemed high. Promash says that would be 3.58 % ABV. I used Wyeast's European Ale yeast 1338

I expected a lower FG and a higher alcohol content.

It has been fermenting at about 65 degrees the whole time.

Do you think the fermentation is stuck, done, or still working? There is a bubble in the airlock every minute or so. Should I do anything, or wait and take more readings in a few days?

Thanks!

that's only 42% attenuation by my calculations...far too low. i'd raise the temperature closer to 70, give it a nice swirl to rouse the yeast, and leave it in the primary another week. you may wish to repitch some dry yeast if that doesn't work.

Yeah, what he said...

At an OG of 65 your FG should read about 16. Then you know it's done and ready to rack to the secondary for clearing...

Agreed. Let it go for a few more days and see where you are at then.

Thnaks guys. The sample tasted good and very sweet (I'm assuming the sweetness comes from incomplete fermentation)

Yes, until the yeast converts the sugar to alcohol. But it'll also stay sweet if you underhopped.
