Azulejos Classic Collection, made of hand-blown glass, have been part of Azulejos since the beginning. Cobalt-blue hand-blown glass is one of the most difficult, intricate, and beautiful of glass colors to achieve. Each bubbles and minor imperfections in the glass give each bottle its character and authenticity. This glass is made from recycled glass as part of our commitment to sustainability. The ceramic label is an authentic Azulejo tile, bringing together the beauty of the glass and ceramic to create a completely unique bottle. 30 years ago, these were one of the first decanter bottles in the tequila industry—and they stand the test of time to this day.
