WATER AND SUGAR
Since 1703, the distillery uses only pure water from its artesian well. It contains minerals essential to the natural indigenous yeasts at the time of fermentation. Mount Gay hand-selects only the finest Barbadian and Caribbean sugarcane molasses for each of its blends. The local Barbadian molasses tend to have a high sugar content and slight acidity, while the Caribbean ones have a more pronounced minerality. The combination of the two strikes a perfect balance between sugar levels and minerality, with a good length on the palate.
Fermentation begins when molasses and filtered Barbados water are combined with yeast. Two separate techniques are used: closed fermentation in stainless steel tanks, used for column distillation; and open-air fermentation in oak vats, used for pot still distillation. In both cases, fermentation lasts at least 72 hours (compared to an average of 24 hours in the rum industry), allowing complex aromas to develop.
