Quarles Harris is one of the oldest Port Houses, being established in 1680, and, over three centuries, has built an outstanding reputation for the quality of its Ports. The company is owned by the Symington family who, through over a century of close involvement in the business, have ensured that tradition and expertise is passed from generation to generation thus maintaining the excellent reputation of Quarles Harris.Quarles Harris Ports are drawn from vineyards in the Rio Torto and Pinhão
valleys of the Upper Douro where Quarles Harris have been making and buying wines from farmers for centuries. In some of these Quintas the wine continues to be made by the time honoured traditional method of foot treading in granite “lagares” which produces first class Port. This enviable position is reflected in the excellent quality and consistency of the style evident in Quarles Harris. "Black in color, with blackberry notes. Deep, dense aromas of crushed dark fruit, with hints of dark chocolate. Full-bodied and medium sweet, with big, chunky, chewy tannins, yet they are polished and beautiful. Excellent persistence."
