Thank you!
AGAVE:Our agaves are 100% Blue Weber, aged 7-9 years, from the rich clay soil of the Highlands of Jalisco, Mexico.
SLOW COOKING:Our agave piñas are roasted in traditional brick ovens for 72 hours, while most others steam theirs for 7 hours.
EXTRA SLOW FERMENTATION:Our unique flavor is a result of an 80 hour fermentation process, compared to the average 48 hours.
PROPRIETARY YEAST:Our Master Distiller uses a special yeast blend resulting in a consistent, refined flavor, unlike the commercial yeasts others use.
COLOR: Rich caramel.
AROMA: Soft caramel and vanilla notes.
FLAVOR: Perfect balance of sweetness from the Blue Weber agaves layered with hints of spice and barrel oak.
WATER: Purified water from our own well.
AGED: 14 months in premium American white oak barrels.

All 100% agave tequilas are fine.
Really no need to ask each brand separately
