Brewed a nice APA recipe (Tiny Bottom Pale Ale - I think the creator is on this forum). Used WLP090 - I'm using a swamp cooler to keep temps in the 60's. Went from 1.052 to 1.015 in 3 days. Then the next 10 days, went from 1.015 to 1.014 only. Keeps bubbling slowly, but maybe that's just gas releasing. The recipe and Beersmith indicates this should finish around 1.010/11. Tastes good, but a tad sweet to me. Used a 1.5L starter. I've also been rousing the yeast by gently rocking the carboy to bring some in suspension the last few days.

What do you think happened here? Is there anything I can do to finish this better, or should I just keg it?

Thanks,
Mark

Last time I used it it finished at 1.005, but there are just too many variables for comparison. I'd say let the beer rise to lower 70's (house ambient?) and rouse one more time. You get a diacetyl rest (though you shouldn't need one) and a chance to see if it kicks in again. If not, I'd say it's done.

I'm new to brewing but my last batch, a rye IPA, I used San Diego Super. OG was 1064 and it only fell to 1017. All the guys on here said it didn't finish and maybe it didn't, but it's been bottled for a few weeks with no bombs, good level of carbonation and tasted excellent last week. Just my 2

I've used WLP090 a couple of times and have had issues with it not finishing. I'm giving it one more shot and if it fails, there's one less yeast to worry about.

Yea, recipe is important. I've never had 090 peter out on me- my IIPA typically finishes fermenting in about 3 days. Are you using oxygen? If you want this yeast to ferment fast and clean as advertised you need to treat it right.

Here's the grain bill (5.5G batch)

8 lbs 8.0 oz Pale Malt (2 Row), Rahr (1.9 SRM) 78.2%
12.0 oz Caramel/Crystal Malt - 15L (15.0 SRM) 6.9%
12.0 oz Vienna Malt (3.5 SRM) 6.9%
9.0 oz Victory Malt (25.0 SRM) 5.2%
5.0 oz Caramel/Crystal Malt - 60L (60.0 SRM) 2.9%

I did oxygenate with oxygen tank and stone. I've just moved it out of the cooler and into the low 70's room temp, and roused the yeast quite a bit by sticking the end of my stirring spoon in there and stirring it up! I'll report back. Thanks for the comments!

I have a Black IPA going for 5 days now using San Diego Super Yeast. It was a 10 gal recipe with 1 pound carafa 2 special, 1 pound C/C 60L, 1 pound midnight wheat. Hopefully i can knock it down to 1.012 from 1.079. My last few beers have all finished higher than I would have liked and it would be nice to finally get a beer down to at least the low teens.

Are you using a refractometer?

Not a refractometer, but I am using a new more accurate hydrometer. It was $20 and marked from .0980 to 1.020.
