When crafting something takes years, and the result is worthy of the effort, the opportunity to make more can be quite satisfying. This is certainly the case for Brooklyn Brewery’s Bel Air Sour Ale.

Originally brewed as part of the Brewmaster’s Reserve Series during the course of 2016, Bel Air Sour Ale is the result of two years of work. Many months were spent isolating the particular strain of lactobacillus used in Bel Air, now a house culture at Brooklyn Brewery.

Upon noticing that fewer and fewer taps of the Brewmasters Reserve version of Bel Air could be found around town, Brooklyn Brewery “decided to say the hell with that, brewed more, and put it in bottles” according to its website.

The dry hopped sour ale features American 2-row and pale wheat malts, in combination with Amarillo, challenger, Mosaic and Perle hops. The release comes in at 5.8 percent ABV and will be sold in 12-ounce bottles in 12- and 24-packs.
