Product Description

Prometheus is a flavour-forward rum distilling yeast and a favourite among rum producers. It is designed specifically for molasses and cane juice fermentations, producing a rich congener profile that carries through distillation and develops beautifully with ageing.

Each sachet contains 22 grams, suitable for fermenting approximately 32 litres of wash. Prometheus is known for producing a wide range of fruity esters, with standout notes of fig and liquorice, making it ideal for full-bodied and expressive rum styles.

This yeast performs reliably at warm fermentation temperatures and offers strong alcohol tolerance while maintaining good yields. It is particularly well suited to traditional rum production where flavour complexity is a priority rather than neutrality.

Prometheus delivers consistency, depth, and character for distillers looking to produce distinctive, high-quality rum.
