Tasting Notes
The distillery's notes: herbal top notes and bright rye spice over crisp apple and vanilla, with clove and a cocoa depth underneath — the liveliest pour of the collection.
How to Enjoy
Neat, or with a splash of water to lift the herbal notes. The high rye build makes it a natural Manhattan bourbon — stir it with sweet vermouth and let the apple and cocoa carry the finish.
