A washed bean has the pulp completely removed before it is dried. This is typically done with a mixture of water and a depulping machine. It is a very good process that does not add a lot of variability to the bean. Meaning, it has a higher likelihood everything will go correctly and the harvest will produce great fruit. I think because this is such a common method it gets a stigma for not being as good. This is completely untrue. Washed coffees consistently score very well all over the world.
The way a washed coffee tastes has a lot to do with this method. You tend to get more of the flavors unique to that origin in the beans. It almost always produces a brighter and cleaner cup of coffee. In a Latin American coffee, a washed bean is going to show more of the caramel or nuttiness so prevalent in that region.
