Sangre de Vida Blanco TequilaSangre 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).
