Produced from a selection of Arinto and Antão Vaz grape varieties, planted in the Eugénio de Almeida Foundation vineyards. When the grapes reach the ideal maturation state, they are harvested and transported to the cellar, where the technological process begins: total destemming and light crushing, pressing, cooling and clarification of the must. Part of the batch ferments in stainless steel tanks, while the other part ferments in French oak barrels at a controlled temperature of 16ºC. After fermentation, there is a period of 12 months on fine lees with periodical batonnage. Finally, filtration, blending, tartaric and protein stabilization, final filtration and bottling are carried out, followed by a final stage of 12 months in the bottle.
