Roughhouse Brewing may have unearthed a holy grail for Texas beer lovers who crave the weird and funky.

The San Marcos-based brewery’s Two & One is a blend of two separate ales aged in caves over a respective one-year and two-year period. That unusual fermentation process yields “wild, sour and funky” flavors, according tasting notes.

Roughhouse will debut Two & One at a Saturday, April 23 kite festival at the brewery, located at 680 Oakwood Loop in San Marcos.

The new creation is the latest release in the Roughhouse’s collection of beers fermented in a natural, underground limestone cave. The the brewery’s Underground series debuted in April of last year with Premiere Texas Cave Ale, believed to be the first beer aged in a natural cave in Texas. The series aims to showcase a complex process of natural fermentation guided by the microbes present within the cave, located on the brewery’s property.

The team at Roughhouse was alerted to the cave via a 2018 geological survey of the brewery’s property, set above the Cow Creek section of the Trinity Aquifer just outside San Marcos. After a long and careful excavation process, the small hole slowly gave way to an underground room, which the brewer eventually outfitted with a small slab, barrel-storing structure, dehumidifier and lighting.

Two & One is the third cave ale released by Roughhouse. The kite festival and tasting will run from noon to 9 p.m. and will feature free live music all day.
