The António Madeira Vinhas Velhas Branco wine is made from rescued local varieties that come from vines aged between 50 and 120 years old. The vines lie at 600 metres above sea level and grow in granite soils. The harvest is carried out manually, the grapes are selected in the vineyard, and fermentation takes place spontaneously with native yeasts. Throughout the process, no enzymes or chemical wine products are used, and only a minimal amount of sulphur is added if needed.
