Café Granja La Esperanza are well known for producing competition winning coffees and experimenting with less common varieties on their Las Margaritas farm, known to the workers as their ‘garden of varieties’ due to the varied and unusual varieties they grow.
The Laurina variety or ‘Bourbon Pointu’ was first planted in Café Granja 10 years ago, since then they have been renovated as part of the farms standard cycle – every six to seven years. If the tree has produced well and was resistant to disease, then they are stumped but if they haven’t performed well then they are taken out and re-planted.
Laurina is a natural mutation of Bourbon which was originally selected on the island of La Réunion in a place called Ravine-aux Chevres in the 19th century. They are dwarf trees which look like Christmas trees, which is how they got the name Pointu (or sharp). It produces coffee which is lower in caffeine than other arabica varieties (0.05% caffeine) and produces a very high cup quality. It is also susceptible to leaf rust, which is why it isn’t widely grown.
Experienced workers pick cherries from this microlot in one day when they are at the perfect ripeness. The cherry is fermented for 36 hours in tanks which are kept in a warehouse which is 22 – 25 degrees Celsius. When this is complete the cherries are taken to a mechanical dryer where they stay for four days, it is switched off for eight hours overnight so there is a break in the drying process. They are then stored once they have reached 11.5% to 12% humidity.
