Zacapa 23 is a super-premium rum made from a blend of rums aged between 6 and 23 years old. It is made from only the sweetest first crush virgin sugar cane honey, rather than molasses, and is aged in a series of casks that previously held American whiskies, Oloroso Sherry and Pedro Ximenez wines in a unique process called the Sistema Solera. The secret of Zacapa is the slow ageing process that takes place at high altitude (2,300m above sea level) in the cool air of the Guatemala highlands.
