Blandy’s Sercial 1968 was aged for 49 years in seasoned American oak casks. Over the 49 years, the wine passed down from the warmer top floor of the Blandy’s Wine Lodges, the “Sotão de Amendoa” to the lower, cooler, north-facing floors of the building. The art of finding the right balance between concentration and the freshness of the wine lies in the winemaker’s decision when to transfer the wine to the lower cooler north facing floors of the lodge.
