Don Q Cristal is a blend of rums aged from 1 1/2 to 5 years in American white oak barrels. A clear, light, premium rum most noted for its mixability and smoothness. A five column distillation process is used to create our flagship rum, filtered for purity. Don Q is the #1 selling rum in Puerto Rico. Puerto Rican rums have long been considered the best rums because by government law they must be aged at least one year.
