Sangre de Vida Blanco tequila begins with slowly roasting the agave pia hearts in stone-walled brick ovens. This centuries-old art of slow-cooking is then followed by cooling, shredding, and finally squeezing the hearts into a mosto (sweet juice), which then ferments for five days, after which is then distilled three times (with its final distillation completed in small stills with even more heat).750 mL
