2026 Still Austin Distillery Reserve Series Four Grain Bourbon 750ml

The Still Austin Distillery Reserve Series 108 Proof is a limited-edition four grain bourbon released on March 30, 2026, as the landmark 20th installment of the Still Austin Distillery Reserve Series. This high-intent collectible bourbon honors the grain-to-glass craftsmanship of Still Austin Whiskey Co. and features a specialized technical label by Austin artist Jeff Skele, who incorporated elements from the previous 19 releases. The technical profile is defined by a unique "lost" mash bill—originally developed for the very first series release but set aside for six years—consisting of 62% corn, 20% malted rye, 16% rye, and 2% malted barley. Produced entirely in-house at the urban distillery in Austin, Texas, this expression utilized whiskey from the distillery's milestone 1,000th barrel and aged for a minimum of seven years. The technical maturation process was influenced by the extreme Central Texas climate, which accelerated wood interaction within the rickhouses to create a high-viscosity, layered spirit. Engineered as a distillery-exclusive release, this bottling was sold online for in-person pickup, making it a primary target for enthusiasts seeking authentic, age-stated Texas heritage spirits that represent the brand’s six-year evolution.
