This yeast rocks. I used White Labs WLP051 (same, Anchor yeast) for the beer below and it came out simply awesome.

Fermented at 65, left in primary for 20 days total, then bottled. Drinking very, very nicely now at 7.5 weeks in the bottle. The hops really come out in this one, with those Nelson Sauvins giving a nice edge to the hop component. Malt comes through nice and rich with the melanoidin malt definitely giving this an extra kick. And the yeast works great with this beer. Didn't dry it out too much. Some nice mouthfeel left there and a nice fruity note from the yeast. This is my current favorite of my beers.
