BrewBlog: Chocolate Covered Cherry Russian Imperial Stout
Specifics
General Information
Method: All Grain

My first attempt at a Russian Imperial Stout.  To get the "chocolate covered cherry" I'm going to add cherry and chocolate extract to the keg.

Comments

Tasting SG sample @ 11 days.  Even though I fermented at 60F there are fruity notes in both aroma and flavor.  The yeast is coming through, not "earthy" as White Labs said for lower fermentation temp.  However strip thermometer on bottle did read almost 67F during peak of fermentation so maybe I should have fermented in the basement where temps were closer to 56-58F.  Sweetness is also coming through but hopefully I will get a little more attenuation over the next week or so.  Bitterness is not as much as I hoped.
