Our primary Winemaker is Robert Diletti of Castle Rock– James Halliday's inaugural "Wine Maker of the Year" (2015). All of our wine is made from 100% Estate Grown Fruit. Mike Garland of Castelli is the Winemaker of the New Block Riesling, and creates the Sparkling wines.

The Invitation wines are made by a local, talented, and exciting Winemaker, who Duke selects each year. Duke’s emphasis is on producing the finest quality of wines, at very affordable prices. Everyone has the right to enjoy good wine. This is reflected in our motto; “...because life’s too short to drink bad wine!”
