Firestone Walker Brewing Co.’s Velvet Merkin is returning to the Proprietor’s Vintage Series in bottles for the fifth year in a row.

The Paso Robles, Calif.-based brewery will once again be releasing Velvet Merkin, an 8.5 percent ABV oatmeal stout brewed with fuggle hops as well as maris otter, 2-row pale, roast barley, English dark caramel, medium caramel and carafe malt malts before being aged in bourbon barrels. The stout originally debuted in 2008, but was first bottled as part of Firestone Walker’s Vintage Series in 2013.

In addition, while Velvet Merkin and the other members of the Proprietor’s Vintage Series have historically been packaged in 22-ounce bottles, all of the releases will be sold in smaller 12-ounce bottles in 2017.

Velvet Merkin will join five other beers in Firestone Walker’s yearly bottle releases of the Proprietor’s Vintage Series, three of which have already been released:

  • Bravo 2017 — barrel-aged imperial brown ale (13.5 percent ABV) — February
  • Parabola 2017 — Russian imperial stout (14.5 percent ABV) — March
  • Stickee Monkee 2017 — central coast quadrupel (13.4 percent ABV) — May
  • Velvet Merkin 2017 — barrel-aged oatmeal stout (8.5 percent ABV) — September
  • Helldorado 2017 — imperial blonde ale (13.2 percent ABV) — August
  • Anniversary Release

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Velvet Merkin 2017 will be packaged in 12-ounce bottles, and there will only be 8,000 cases produced. A post on Firestone Walker’s  website indicates the beer will be released in in September.
