The highlands of Guji rise from fertile red earth and ancient forests, where crisp mornings and bright sun shape coffee with vibrance and clarity.

Here, the story returns to Kaldi’s farm, where the legend of coffee first began, carried on by smallholders who nurture each tree with care. I roast these beans to reveal their nature—strawberry, blueberry, and sweet citrus. It’s a lively cup, bright and layered, the one that sparks a sense of discovery.
