40% ABV, this is a sleeve of 10 bottles x 50 ml "mini-"bottles of Cuervo Tracicion Silver Tequila.
"Tradicional® Silver is 100% blue agave silver tequila. It is irresistibly refined. When bottled, a special process is used to conserve its flavor and finish at freezing temperatures. This means that it can, and should, be kept chilled in the freezer and served as a crisp, smooth, frozen shot."
