Seco Herrerano is considered the national alcoholic beverage of Panama. Triple distilled from sugarcane, it is traditionally used straight or in mixed drinks as a replacement for rum or vodka. It is a clear liquor that is sold at seventy proof. There are actually multiple brands of Seco, but Herrerano is the most widely available and popular of all brands.
The most common mixers for seco are milk (colloquially known as "seco con vaca") and coconut water.
