Butterscotch Smell

[mresa641]

I just finished a batch of cream ale from NB. The taste is really great but it has a distinct butterscotch smell. Is this a sign of green beer or should I expect something that hasn't come down to the flavor yet?

I used honey malt, biscuit malt and 2 row. American Ale Yeast (harvested and washed)

Sounds like diacetyl. Is it still in primary? If so, just let it sit for a little while longer and it should (hopefully) clear out. Here's the wiki article: https://www.homebrewtalk.com/wiki/index.php/Diacetyl
