This is a Mission Wine & Spirits Exclusive single barrel bottling. Barrel number is 16602 and says it was New European Oak (whatever exactly that means). Distilled 2/27/17 and bottled 11/2/20 - so what's that make it, 3 years and 7-ish months old? 64.2% ABV / 128.4 proof. N: Vanilla custard and torched brown sugar - yeah, it's creme brulee in a glass. And intense. Also, chocolate orange, toasted almond, just a hint of smoked meat. Ethanol in the form of cherry cough syrup, but far less than you might expect for the proof. Vanilla frosting on a yellow cake. Butterscotch candy. Basically, this is a bottling of all of the desserts. P: Sweet red apple dripping with caramel, then rolled in salt. Hints of vanilla, citrus, chocolate, and cooked brown sugar, all also salted. Salted dark red cherries and other red fruit. It's quite salty, but doesn't cross over into being offensive in that way. Finish turns oddly herbal with mint, menthol, and maybe a hint of rosemary. It remains quite sweet and salty and develops a bit of a papery quality - feels like the wood finally being a bit woody. I'll start by saying that it appears this barrel is gone from the world - Mission no longer offers it on their website, so I have to assume they've sold out. So there's not much point in thinking too hard about this particular pour, just happy I still have a third of a bottle left. I suppose though that this can/should be thought of as presenting one component part of the core Balcones line. I just realized while writing this that, well I've enjoyed many bottles of Balcones, I have not yet tried their core single malt. I can't compare it. But I would say the flavors here do show up in other Balcones malts, and some of their bourbons too. The vanilla in particular feels like a Balcones flavor that appears regularly in their bourbons. I'm not sure how to wrap this review up and end this. I guess, at this point, I've basically decided to try anything from Balcones I can get my hands on. They just really know what they're doing and every bottle from them I've tried has been quality. And this is one of the best I've tried from Balcones. _______ Please come join a bunch of regular Distiller reviewers are chatting spirits in real time on Discord: https://discord.gg/4nfePCdyKM.
