The unique flavour and profile of Casamigos Tequila comes from our extra-slow fermentation process. Ours takes 80 hours, which is double the industry standard. The use of bagasse from our agave for the fermentation process also generates a richer, deeper flavour, while our proprietary yeast blend ensures the most refined tequila.Casamigos Tequila is a small batch, ultra-premium tequila made from the finest, hand-selected, 100% Blue Weber agaves, which are grown in the rich, red clay soil and cool climate of the Jalisco Highlands of Mexico. The agaves are harvested after maturing for a minimum of seven years and are hand-chosen for size and quality. A slow fermentation process results in a deep, rich flavour, and a tequila thatís as smooth as it gets. 92 Points Wine Enthusiast.
