match-oo-RAY-shun/ˌmætʃuˈreɪʃn/
The process of becoming fully developed over time.

Etymology
The verb meaning “to ripen” makes maturation a process of ripening. Applied to children as well as fruit, the word describes development toward a fully grown state.
In context
you want to feed the fruit of the tree with loads of sunshine, but then you want cool nights to slow the maturation process. That gives you a denser coffee seed
