This gets incredibly complex as it warms up. I was a bit afraid of the brett besides the word "barrel aged" and "quad", but the balance is definitely there. Slightly boozy, but ripened plums with a nice balance on the sugar side. Unable to tell what the barrel was. Something like 2nd used cognac, maybe?
Can't say it's worldclass, but can't say it's bad either. Wouldn't drink this every week, but it's definitely a nice balanced beer that you can go through very easily.
