Mas Doix's Salanques vineyard sits in the heart of Priorat's slate terraces, where old Grenache vines benefit from the region's rocky, mineral-rich soils and the Atlantic-influenced climate that tempers summer heat. The estate practises sustainable viticulture, using natural cover crops and minimal intervention in the vineyard to preserve soil integrity and plant health. The 2021 vintage saw moderate temperatures with adequate spring rain and a warm, dry summer — ideal conditions for balanced phenolic ripeness without excessive alcohol development. Harvest took place in early October, with careful fruit selection ensuring only optimal berry maturity entered the winery.

Salanques undergoes careful fermentation in temperature-controlled open vats, where indigenous yeasts drive a slow, extended fermentation lasting three to four weeks. The winery employs a combination of foot-treading and pump-over to achieve gentle extraction and phenolic maturity. Following fermentation, the wine rests in a mix of French oak (roughly 30%) and steel to develop complexity while retaining freshness. Malolactic conversion occurs naturally over several months, and the wine spends 18 months in this medium before final assembly and bottling with minimal fining or filtration.
