Woodford Reserve announced the release of a limited-edition bourbon to celebrate Bourbon Heritage Month: Woodford Reserve Four Grain.

The whiskey is a blend of the distillery’s four main expressions: Woodford Bourbon, Woodford Rye Whiskey, Woodford Malt Whiskey and Woodford Wheat Whiskey.

Four Grain is part of Woodford’s annual Distillery Series, which distiller Chris Morris created to highlight Woodford Reserve’s innovation. There are three annual releases of the distillery series.

The 90.4 proof bourbon will retail for $49.99 per 375ml bottle, and will be available via curbside pickup at the distillery starting on Sept. 16. Bottles also can be ordered online and will be available this fall at a small number of Kentucky retailers.
