1994 was the beginning of modern Rioja, and Marqués de Murrieta considered it to be a very high quality vintage, with 20% lower yields than usual, giving wines great tannic structure and the ability to age well. The 1994 Castillo Ygay Gran Reserva Especial, produced with a blend of 75% Tempranillo, 13% Mazuelo, 10% Garnacha and 2% Graciano, matured in oak barrels for 50 months. It has 13.4% alcohol with 7.4 grams of acidity and 0.7 grams of volatile acidity, and it has tannic structure. In this decade, the winery had a big influence on the wines; there's more noticeable oak here despite a shorter élevage. The oak was still 100% American. The wine was bottled in May 1999.
