So my Peanut Butter Brown Ale has been fermenting for about 3 weeks now. I took a sample and it has this great peanut butter aroma and nutty taste. The only problem I ran into, and I had this with my ESB when using the same yeast, a dry almost astringent flavor that lingers in the finish. And its not off setting, but it is not a flavor I pull from drinking an ESB or Nut Brown by a microbrewery. Has anyone had the same problem with this yeast strain?

So I had White Labs email me back today after posing this question. They responded with...
"It could be a lot of things, including contamination. But if it is just
with WLP005, perhaps it is fusel alcohols. The British Ale yeast produces
more then other strains, so this may be coming through in the beer. Lower
fermentation temperatures reduce fusel alcohols. Hope this helps and if you
have any other questions don't hesitate to write."
