Straight Bourbon Of The Year - Maker's Mark Cask Strength 2026 London Spirits Competition - Rated 96/100 Bottled at barrel proof, Maker’s Mark Cask Strength it’s the boldest representation of our craft. It’s a whisky that provides a deepened experience of our signature tasting notes, with amplified notes of dark cherry, toasted oak, salted caramel, plenty of warm vanilla and a harmonious finish of dark chocolate and soft spices. Cask Strength is made from the distillery’s classic mashbill of 70% corn, 16% soft red wheat, and 14% malted barley. Each batch of Cask Strength is aged to perfection for a minimum of 7 years, when it reaches the perfect balance of flavor and is bottled in small batches. This means that each release is unique, yet every drop is unmistakably Maker’s Mark.
