375mL bottle drunk 12/31/18.
Good clarity, leaving sediment behind. Deep chestnut-to-auburn with light mahogany. Dark buttery-beige head fizzles quickly to nothing.
Nose shows strong wood tannin, mineral, strong acetic and lactic acid with good Brett fruitiness. Overall it's a mix of aggressive and enjoyable (though I don't mind the aggressive, really). Doesn't remind of vinegar or balsamic, thankfully. Seemingly very well-attenuated with hints of tart cherry, raisin, other dried red fruits and strong cereal/biscuit underneath. No alcohol or flaw.
In the mouth it's highly acidic/sour initially, though the palate does accustom itself quickly. Cherries are brilliant and nicely attenuated/integrated with other red fruits, hints of dark bread, cereal and tons of lactic and acetic acid. The Brett is there and maybe not quite as strong/prominent as I'd like, but it helps take some of the focus off of all of this strong acetic character. Dry, biscuity-to-malty texture with fine carbonation and lingering oak and light mineral/grape character. Very complex indeed and nicely done, though it wouldn't hurt to tone down the sourness just a bit here.

Bottle - pours reddish tan head - nose and taste of wine, cherry, oak, funk and cherry pie - medium body

Bottle at the Side Project Cellar. Pours mostly clear, reddish brown with a frothy, light tan head. Dense tart cherry in the aroma, with hints of wood, cinnamon, faint toffee; it smells beautiful. Light sweet flavour with rich, true and lightly chewy tangy cherries, some wholegrain bread, impressions of cocoa perhaps, grape. Light to medium bodied with spritzy, massaging carbonation. Tart and refreshing, with further meaty cherry notes, moderate tartness, faint earth and wood, currants. Wow, superlative. The depth and balance of the cherry character is phenomenal.
