The iconic 2023 Reserva Old Vines, or Reserva Vinhas Velhas, is a textbook modern red from Douro showing the complexity and nuance of the old field blends on schist soils with generous but nicely integrated oak and a commercial and approachable, showy profile. In 2023, it has good freshness, ripeness and 14.5% alcohol, with a pH of 3.71 and 5.4 grams of acidity. It's medium- to full bodied and fine-boned. It matured in 85% French and 15% American oak barrels, 65% of them new, for 18 months. It was bottled from November 2025.
