A blend of Tabi and Yellow Colombia from two experimental Huila farms: Nestor Lasso's El Diviso (1,780-1,900 m) and the Vergara family's Las Flores (1,700-1,790 m). A two-stage fermentation, aerobic and then anaerobic under water, builds stone-fruit flavour before a hot-and-cold water shock locks it in.

Oscar and Francisca Chacón run their farm in the third generation and joined Costa Rica's "micromill revolution" in 2005, building their own mill to control quality. When an earthquake in 2008 cut power and water mid-harvest, Francisca built raised beds on the spot; they have since become pioneers of the country's honey and natural processing.

Rösttrommel's first Laurina: a rare, hard-to-grow natural Bourbon mutation with only about 0.8% caffeine (against the usual 1.8% for arabica). Supriyanto grows it on the slopes of Mount Suket in the Ijen range from seed supplied by PT Perkebunan Nusantara, with the Indonesian Coffee and Cocoa Research Institute; the local microclimate gives slightly larger beans with the typical pointed shape.
