The opulent fruit sweetness and winey complexity of Guava Cake are forged entirely by time, sun, and traditional natural processing, capitalizing on the distinct microclimate of Acatenango.

Everything begins on the shaded, volcanic hills of Finca La Merced, where pickers selectively hand-harvest only crimson,fully ripened Bourbon cherries at peak sugar density. Before drying, the harvest is floated in clean water to skim off lower-density cherries and carefully sorted by hand to eliminate any underripe fruit, ensuring only flawless cherries move forward. Rather than pulping away the fruit, the cherries are kept completely whole, retaining both the outer skin and the sugar-dense mucilage. They are spread out in thin layers across sunlit patios and raised beds, stepping right into the heart of Acatenango’s harvest season. This climate is blessed with clear equatorial sunshine, cool nights, and dry, steady mountain winds that act as an ideal natural dehydrator. Over the next two to three weeks, workers turn and rake the fruit multiple times each day from sunrise to dusk.

This continuous, attentive movement prevents over-fermentation, encourages even airflow, and allows the ambient heat to concentrate the cherry's native sugars. As the fruit slowly dehydrates into a deep, raisin-like pod, the seed absorbs the surrounding organic acids, pectins, and aromatics. This slow transfer is what gives the cup its vibrant signature notes of tropical guava, blood orange zest, and syrupy winey depth. Once the cherries hit a precise, shelf-stable moisture content of 10.5% to 11.5%, they are gathered into hermetic GrainPro bags for a crucial resting period (reposo). Resting the dried pods in a temperature-controlled warehouse for several weeks allows water activity to equalize and locks in the volatile flavor compounds.

Only when the lot has fully settled is the dried husk mechanically milled away, unveiling dense green Bourbon seeds ready to brew into a decadent, fruit-drenched cup.
