According to the label, they literally threw coffee beans in barrels of Kentucky Bastard, so that would be bourbon. I had a sample and it was really good. A lot of coffee. Bourbon was quite subdued. I would need to drink more to give more insight, however, I definately recommend picking up a bottle. Pretty much the same price point per ml as most Bellwood's barrel aged beers.
Sounds promising.I think I prefer classic Bolshevik to Kentucky Bastard so I could probably get in on a more coffee-forward version. Not sure I'll be able to get out to Burlington in time though. Shame this one isn't headed to the LCBO.
