From the roaster

China's specialty coffee moment is here, and Yunnan is leading it! Grown in the misty highlands of one of Asia's most unexpected origins, this Catimor is transformed by anaerobic natural processing into something genuinely special: white grape brightness, soft peach sweetness, and a sweet, warm, wine finish that lingers long after the last sip. Approachable and elegant in equal measure.

Context

This natural-processed coffee from Yunnan in China represents an intriguing application of anaerobic fermentation to the Catimor varietal. Yardstick Coffee emphasizes the method's capacity to amplify fruit-forward character: white grape brightness pairs with soft peach sweetness, while a wine-like finish suggests the extended anaerobic process has encouraged complex fermentation notes. Natural-processed coffees tend toward heavier fruit expression, and this lot appears to lean into that tendency while maintaining approachable sweetness rather than aggressive funkiness. The combination of regional terroir, varietal character, and controlled fermentation creates a profile worth exploring if you're curious how processing innovation shapes flavor in less traditional coffee origins.
