According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Lagunitas Brewing Co. is working on releasing Sonoma Farmhouse Brett Stout, an 8 percent ABV imperial farmhouse stout brewed with brettanomyces, lactobacillus and the brewery’s house yeast before being aged in red wine barrels from Sonoma county for “up to four years.”

The stout will be packaged in 22-ounce bottles and will join Lagunitas’ OneHitter Series, which is made up of seasonal releases.

An email sent to the brewery for additional information was not immediately returned.
