Agave Tequilana: How to Grow Blue Weber Agave

Blue Weber Agave, Agave tequilana

A daring husband and wife team in Sonoma county—Laurie and Adam Goldberg, co-founders and owners of  Stargazer Spirits—is experimenting with large-scale agave farming by planting test blocks on approximately six acres of varying soil types, with blue Weber as one agave variety. They are deep in the learning stage, so I reached out to Laurie for advice and insights into growing blue Weber agave, a historically significant succulent.

Please keep reading to learn more about this drinkable plant and this adventurous couple.

First, a little backstory about blue Weber agave: The Greek word that agave comes from is Agavos, which translates to illustrious; in Greek mythology, Agave was the goddess of desire. Blue Weber agave is native to Jalisco, Mexico, and was considered sacred by the Aztecs. The first alcoholic agave beverage was pulque (potentially dating back to 1000 B.C), made from the fermentation of the plant’s sap. When Spanish settlers entered the scene, they began experimenting with the distillation process, eventually using the pulque to make tequila and mezcal. Today, Jalisco remains the source of the best and the majority of tequila.

The Goldbergs’ mission is to create top-notch agave spirits in California. (Side note: in order for a drink to be called tequila, it must be made from blue Weber agave in Jalisco or other limited municipalities in Mexico.) They are among the first to grow agave for spirits production outside of Mexico. “We have around 3,000 tequilana (including several heritage varieties) and approximately 6,000 plants total. We’d hoped that Agave tequilana would be a low-water, low-maintenance, set-it-and-forget-it plant for us, but in fact it requires more water than any of our other agaves (though still around 75 percent less than what grapes need on a per-acre basis),” shares Laurie. The Goldbergs continue running a number of soil amendment, mulching, and watering experiments. “The bottom line is that this agave is likely to thrive in warm areas in full sun without winter frost. It requires 70 to 80 gallons of water per plant in the summer months, though water requirements will depend on location and soils. Lastly, it likes loose, sandy soils in which its roots can spread out.”
