Fino Arroyuelo is produced by Primitivo Collantes, an artisan bodega rooted in Chiclana de la Frontera, in the heart of the Marco de Jerez. The wine comes from Viña Matalián, a vineyard planted on the region's prized albariza soils — the white chalky limestone-clay that retains moisture and lends a distinctive mineral tension to the fruit — with 100% Palomino Fino, the emblematic variety of Jerez.

Fermentation is spontaneous and temperature-controlled at 22–24°C, after which the wine is fortified to 15% ABV and aged for a full five years under the veil of flor via the traditional criaderas and soleras system — an exceptional ageing period for a Fino that goes well beyond the standard three to four years of most Marco de Jerez Finos.
