I heard White Labs had some issues with WLP002 recently and stock was in short supply for the past few months. I finally got my hands on some and pitched it into a recent batch last week Saturday. But first, a little background:
With my fermentation equipment and setup, most of my batches hit FG within ~2-3 days. I'm at 3.773 days and it would appear that we have stalled out at 1.027 (with 10 points to go until target FG). I'm holding at ~52.63% apparent attenuation which is just not enough.
I lightly rolled the fermenter a few times to rouse the yeast, and you can see that I raised the temp to encourage the yeast to finish up. I even pulled a sample to test with my refractometer, and it confirmed that I'm at about 1.025-1.027 (pending some variables).
I'm sure if I let it sit for a week or two, it'll drop a few more points, but I have a hard time seeing this drop another 10 points.
Does anyone know what kind of problems White Labs was having with this strain? The tube I bought arrived off the truck that day and was packaged maybe 2-3 weeks before it was pitched. Is it possible that I might be experiencing some of the issues that caused WL to hold off distributing this strain?
Any thoughts/tips?
- I ferment in a stainless steel Anvil bucket fermentor
- My fermentor sits in a temperature controlled chest freezer
- I own a Tilt hydrometer, so I know exactly what's going on with my fermentation
- I always aerate my wort with pure O2
- I always use yeast nutrient in every batch
- I almost always hit max advertised attenuation
- For the first time in 2 years, I did not make a starter, but my OG was only 1.057, so I thought it was safe to skip just this once.
