Quinta de Vargellas, named one of the top 100 vineyards in the world, has been part of the Taylor Fladgate estate for over a century. With the highest percentage of old vines of any quinta in the Douro, 60% are over 75 years old. Grapes are harvested from the oldest vineyard plot, which yields Vinha Velha (old vine) intensity. Grapes undergo traditional foot treading for fullest expression. Fermentation is halted by adding grape spirits before all residual sugar has been fermented, creating a sweet, fortified wine. After 2 years in wood, the wines are bottled unfiltered and will continue maturing for decades. From low yields, production is extremely limited.
