A mixed fermentation bourbon barrel aged blend of flanders reds...yes please! This one is limited batch and going to be special just like the last barrel aged flanders red I had from them. A merky ruby colour, less brown than other Flanders red brews I've had before, it's actually red this time! It's very fruity in the nose absolutely bursting with raspberry. I'm not picking up any bourbon...maybe a slight hint of oak at the end. But then these barrels aren't freshly taken from a whiskey producer, no, they've been used for other barrel aged beers before this one. So less whiskey more funk I guess. Ooh that's sour! And sharp as fook! It disappears quickly though so isn't terribly uncomfortable. Second sip is fine, though still sharp on the teeth. It's very dry is my first impression and yes loaded with raspberry to the extreme. I'm getting the oak, not very pronounced mind you, it's more adding to the dryness, giving a woody feel that's expressing itself slowly. I'll have to come back to the barrel aged element. As for Flanders style...the salt sits on the tongue and accumulates quite rapidly actually. And the balsamic vinegar side merges with the raspberry making it sharper, in an extreme but pleasant way. It's rich with raspberry and that overshadows the other influences on this brew for me. I've taken a dinner break and come back to it...now is say it's sourness hasn't depleted and also the dry wood finish is still true and call me crazy but it's doesn't taste like bourbon barrel wood but old sour beer wood with a touch of vanilla of the original oak. So really it's a massively raspberry sour with oak. Kind of disappointing compared to a more explicit bourbon influence or other brews but it's still an amazing brew and more than a raspberry sour.
