Imagine my surprise when I opened a bottle of my cream ale and found that it had picked up a clove-y flavor reminiscent of a wheat beer. It's not even presented as a risk in the BJCP guidelines for cream ale.
It's pretty clear that the flavor I'm tasting is 4-vinyl guaiacol, but it's not clear where the heck it came from.
I used Safale S-05 dry yeast and fermented at a pretty steady 65°.
By the way, it's delicious. I doubt I could replicate it, but I would if I could.
