WLP099 Super High Gravity Ale Yeast

[bsegroves]

Herro,

I brewed a Russian Imperial Stout 4 weeks ago and pitched a healthy starter of WLP099 Super High Gravity Ale Yeast.
The O.G. was around 1.082.
4 weeks in the primary later, there is still activity coming out of the airlock.
I was thinking I would take a gravity reading today, but since it isn't done yet I decided to wait.
Does anyone have experience with this yeast?
I would like to transfer the beer to secondary to free up the bucket for something else, but I don't want to rush it.
How long could it go on?


cheers,
Brannon

You can check the gravity with no problems.

Yes but if it is not done yet wouldn't it be unnecessary?

I had to know.
It's 1.020 right now and it tastes delicious!
Still bubbling though so I think I'll let it sit for another week before racking to secondary.
Its 76% attenuated and the yeast can go as high as >80%.
Sound good?

74.3% AA so you are getting close. You could rouse up the yeast some, to get a bit more activity. Either GENTLY swirl the carboy or use a sanitized racking cane or sample theif to stir it up with. I would think you get get it down another point or 2. Then go to secondary when it is stable.

Thanks Brandon.
How did you do your math for the ATN?

I subtracted 82 - 20 = 62 / 82 = .756 = 76%

Did I do it wrong?

I used brewcalcs.com . Its a free site, I think one the posters either over here or at more beer's forum built that website

Allright.
Thank you!
