Hint:from Esporão and it’s not Port!
Quatro Castas means literally four cépages, or four varietals. To pique your curiosity further, it’s made of equal parts of Touriga Nacional, Trincadeira, Syrah and Alicante Bouchet. For the sake of learning, let us review first the local Portuguese grapes. Touriga Nacional is mostly associated with the production of Port wines. Well, in fact most of all indigenous grapes in Portugal such as the ones listed here, are associated with Port production since Port wine could be made of up to 100 different grapes. Trincadeira, is the local name of Tinta Amarela which is widely planted in the Alentejo Region, it produces rich red wines of full body. Alicante Bouchet is the local name for Garnacha Tintorera, which is a teinturier grape of red skin and pulp used mainly for adding color and structure to red and Port wines.
Quatro Castas is a full body wine with heady and spicy aromas that might require pairing with a slab of steak to complement the abundant dark plum and dark cherry flavors framed by medium weigh tannins. It finishes persistently earthy with cocoa notes. What you may like the most is the QPR at $16.00 per bottle. I bought this bottle at Seabra Super Market in Attleboro, MA.
