Various types of French oak casks are used for ageing, as they are the ones best suited to Arrayán's wines. Cask size and age depends on the needs of each wine.
Coopers: Taransaud, Darnajou, Saury, Demptos, François Frères, Adour.
Grapes are mainly harvested manually, in 20 kg crates, and then transported to the winery, which is very close to the vineyard.
Grape temperatures are homogenised in a refrigerated trailer before reaching the winery.
Bunches are hand sorted and vetted for health, then destemmed and transferred to small fermentation tanks made of stainless steel or French oak.
Fermentation occurs spontaneously with the grapes' natural yeasts. Once the process is complete, the wines are racked into steel vats or wooden casks, depending on the wine, where they undergo malolactic fermentation.
