Flavour Development MOC¶
Flavour in coffee is not a fixed property of the bean — it develops and transforms at every stage from cherry to cup through a chain of genetic, environmental, biochemical, and physical processes. The foundational precursors form during cherry growth and ripening; processing and fermentation reshape them; roasting's heat reactions create the majority of the cup's volatile and non-volatile compounds; and extraction determines which of those compounds reach the cup in what proportion. This MOC maps flavour development across each stage and connects to the sensory science of identifying and evaluating what is in the cup.
