Espresso Brewing for Costa Rica Coffees

Coffees from Latin America is usually very easy to handle. As they are grown at altitudes from 1400-1700m. The cellular structure is more uniform and makes it easier to calibrate when dailing in your espresso shot.  

At this altitude the cellular structure is uniform. And very little adjustments have to be made. Some rare coffees from Costa Rica are grown at a higher altitude as 1900-2100 m. And as a general rule = higher altitude = coarser grind setting / as the cellular structure is more dense. In this case I would also recommend a shorter extraction time 19-21 sec. And no rules without exceptions / Anaerobe / Cabonated coffees with same principle. 

They coffees can be extracted from 19 sec to 31 sec. and still tasting harmonious with a delicate balance. Your highlight here should be sweetness and medium to low acidity. Tactile balance has to be medium to low weight. Costa Rican coffees are usually light, smooth with a delicate structure.
