"Sandra Farms, located in the midwestern mountains of Puerto Rico, has been producing sustainable, small-batch coffee since 2001. The farm, sitting at an altitude of 2,500 feet, offers guided tours to educate visitors about traditional methods of growing and harvesting coffee, focusing on sustainability. The farm uses zero fossil fuel and recycles biomass and compost. Sandra Farms produces both naturally processed and washed coffees, with naturally processed coffees being fuller and fruitier." - Herson Guerrero
