The same variety, grown on the same slope, can taste very different depending on how the fruit is taken off the seed.
Washed
The fruit is removed before drying. The cup is usually cleaner and brighter, with the character of the variety and the altitude in front.
Honey
Some of the sticky fruit layer is left on while the coffee dries. Expect more sweetness and body, with softer acidity.
Natural
The whole cherry dries intact. The cup is fruitier and heavier, and a good natural is sweet and clear rather than fermented.
