Blue Weber Agave is the only species of the agave plant that is used to make Teremana. Teremana Agave is grown at the highest elevations of the Jalisco Highlands, at about 7,000 feet above sea level.  This elevation stresses the agave plants and produces a naturally sweeter tequila.  Our agave is only harvested when they reach peak maturity, often taking between six to eight years.
