Block 15 Turbulent Consequence Premiere Annee
While American craft brewers release wild ales and beers fermented with “brett” around the clock nowadays, brewers who utilize spontaneous fermentation are still a lot rarer. Block 15′s Turbulent Consequence Première Année is a “spontaneously oak barrel fermented ale” that is brewed each fall and spring according to Belgium lambic tradition. That means a turbid mash, unmalted wheat, a long boil, aged hops, and cooling of the wort in a coolship before barrel aging. This bottle is a 2012 selection of two barrels and bottled with honey (!). As such, the beer is an interesting approximation of a Belgian gueuze, albeit a little on the younger side.
The beer pours a cloudy, burnt / golden orange; the head disappears quickly after pouring, producing a flat appearance. The aroma is fairly complex. Lactic notes dominate in addition to sweet, lemon, funky, “wet cellar,” and brettanomyces notes. The taste is dry, lemony and puckering. Despite its flat appearance, carbonation is moderate, mouth feel is moderate, and there is some astringency from the barrels. This is a dry, light, and refreshing beer. Despite its low alcohol (5.8%), I would not characterize this as a session beer. It’s quite sour (at least the bottle I had), even for people who enjoy this kind of thing (me).
I cannot praise Block 15 highly enough for their ventures into spontaneous fermentation. I’d say that this beer is still a little young and raw and it lacks the complexity and depth of Belgian lambics but spontaneous fermentation and blending is an art that takes many years of experience to perfect. Strangely enough, I would say that this blend could have benefited a little from “something else” (a stronger oak note, botanicals etc.) to take some of the edge of the puckering lacto but that would have made it a different beer. I don’t know if the sweet aroma came from the honey that was added to the bottle, but I do like this natural approach to create carbonation because it adds a little complexity and allows the beer to ferment to dryness.
