ZRNCO

ZRNCO is run out of Opatovská cesta in Košice by Natália and Juraj, who describe their path into the business as growing from simply buying and tasting specialty beans into becoming buyers of "exceptional, select green beans" and roasters in their own right — the company is registered as a family roastery, rodinná pražiareň kávy. Sourcing runs through single-origin lots from Peru, Colombia, Ethiopia, and Brazil, all 100% Arabica and all scored above 80 points on the SCA specialty scale, a stated cutoff rather than a marketing label. Rather than roasting to stock, ZRNCO roasts after an order is confirmed, and the company is specific about the freshness window this creates: optimal flavor from day six through week five after roasting, a level of detail that suggests the claim is measured rather than asserted. Alongside bagged beans, the shop sells its own branded grinders and espresso cups, along with tasting sets and gift packages built around the same single-origin lineup. For a small, two-person operation working out of one city, the roast-to-order model and the explicit sourcing detail — named countries, named quality threshold, named freshness window — give ZRNCO a level of specificity that a larger roaster selling pre-roasted stock typically can't match.
