Simply put, Colheita is a vintage-dated, Tawny Port. Infantado’s Colheita is unique as all the grapes come from 100% “class A” vineyards. In addition, the minimum aging in 500 liter casks, which are more than a century old, is for seven years before bottling. The Colheita is made through gradual oxidation and concentration, resulting in a golden brown color and complex nutty flavors. The wine will keep for months after opening.
