Beans & Processing

Experimental processing

An experimental processing method is a way farmers prepare the raw coffee fruit after harvest that goes beyond traditional sun-drying or washing. It works a bit like deliberate fermentation in winemaking, where farmers might seal the whole fruit in airtight barrels without oxygen or introduce specific yeast strains. This process changes how the seed absorbs characteristics from the surrounding fruit pulp, leading to completely new and unexpected results. In the final cup, this translates to highly unusual tasting notes that can remind you of tropical fruits, cinnamon, strawberries, or even bubblegum. Because this approach requires immense precision and constant monitoring at the plantation, these coffees only reach the roastery in very small, rare batches.
