Catuai is a dwarf varietal that is highly resistant to the natural elements coffee trees face at high altitude as well as being highly productive in terms of yield. Catuai is a hybrid of the Mondo Novo and Caturra varietals and originates in Brasil. It is now found prevalently throughout Central America. Cherry can ripen into both red and yellow forms and for as long as I can remember nobody thought there was a difference. A few weeks of Central American cuppings in early 2007 led Stumptown to believe, however, that the yellow strain produces inferior cup quality by comparison to the red strain. Although both have “big” acidity, the yellow seems to develop an unclean, petroleum-like mouthfeel as it cools. The red catuai strain seems to maintain its cleanliness.
