Description

“Mercaptan, like drains or soft white cheese”

Certified cider flavour standard used to train professional cider tasters to recognize and scale the intensity of mercaptan character.

Methanethiol arises as a result of yeast autolysis at the end of fermentation or during maturation. Formation of high levels can be due to a deficiency of amino acids in the apple juice prior to fermentation. Methanethiol imparts a sulphury character to cider reminiscent of drains or rotting garbage.
