Colombian Rum-Aroma Coffee Flavor - Colombian Coffee Estate's Aged Oak Barrel Treatment Creates Captivating Rum Fragrance

FrontStreet Coffee - Introduction to Colombia's Finca San Jose Estate

Colombia's Finca San Jose Estate has been actively seeking breakthroughs to forge its own unique path amid the prevailing trend of specialty coffee in recent years.

One day, while accompanying her husband — who manufactures rum oak barrels and produces rum — as he filled rum distillate for fermentation, the estate's owner Monsalve Botero had a sudden inspiration: what if raw coffee beans were placed in oak barrels to ferment? Could that create different flavors? From 2013 onward, Monsalve Botero experimented with Colombian oak barrels of different ages and varying fermentation times, using winemaking-style low-temperature fermentation. Finally, in this batch, she found the flavor she was looking for, creating a refined washed coffee — rum barrel fermented beans — that differs from traditional washed processing.

FrontStreet Coffee Recommendation

If innovative fermentation is what draws you to this rum barrel lot, FrontStreet Coffee's Colombia Sidra follows the same pioneering spirit. Grown at 1650-1800 meters at the dividing-line estate and processed by double anaerobic natural fermentation, it converts the beans' native character into rich tropical fruit aromas — passionfruit, grape, apricot, and dried fruit — with a medium-light roast that keeps jasmine and citrus in the dry fragrance, light spice in the middle, and a lasting cocoa finish. It suits hand brewing, espresso SOE, and cold drip alike.

Prefer the classic Colombian profile? The FrontStreet washed Huilan lot, roasted medium-dark, highlights black chocolate, nutty sweetness, moderate oils, and a mellow body — at home in a pour-over or French press, and equally capable behind a moka pot or espresso machine for Americanos and lattes. For milk drinks, the FrontStreet Premium Espresso Blend pairs Brazil's creamy nut character with Colombia's dark chocolate bitterness for a fine golden crema.
