The 1991 Castillo Ygay Gran Reserva Especial comes from a vintage they considered very good and with the tannic structure to age well. It was produced with 75% Tempranillo, 13% Mazuelo, 10% Garnacha and 2% Graciano that matured in tank for four months followed by 60 months in American oak barrels of different sizes. It was bottled in July 1997 with 13.3% alcohol and 7.3 grams of acidity and 0.75 grams of volatile acidity. 1991 felt a bit more classical, with balance, fruit and structure and more integrated acidity, than the wines from the 1980s. There is a touch of meat and leather. It's medium-bodied and balanced.
