I'm not sure how long I've been hoarding this bottle of Alvinne Kerasus, but not as long as the "Vintage 2009" designation on the label might suggest. I've probably only had it since about 2011. Unhelpfully, no best-before is given on the bottle, nor even an ABV: on the unlawful side of artisanal, then.
It presents in my kriek glass a hazy maroon with no head to speak of, just a smattering of lazy bubbles breaking the millpond surface. On the nose it's a classic sour kriek, all saltpetre and balsamic, with barely a trace of fruit. The taste begins with a puckering tang followed quickly by a deeper brett-like funk, though I'm not aware that there's any brett involved in Alvinne's proprietary souring yeast strain Morpheus (more on it here). And then the cherries roll in at the end, warming and rich, like the filling in a hot fruit tart.
It's a beautiful sipper and while perhaps not as classically clean as the big-name Belgian krieks, it has a depth and complexity all its own. Worth waiting for.
