Wiese & Krohn was founded in 1865 by two Norwegians - Theodor Wiese and Dankert Krohn - shipping initially to Scandinavia and Germany. In the century and a half since its foundation, Krohn has built up an outstanding reputation. Long renowned for the quality of their sublime Colheitas (single vintage tawnies), they produce a remarkably complete range for a small house, and each wine excels in its category. Much of the secret lies in the high quality of their vineyards - the magical combination of terroir, locality, aspect, incline and low-yielding vines. Their Quinta do Retiro Novo estate in Sarzedinho, in the Rio Torto valley (where vinification takes place), is all A grade vineyard. Indeed Krohn only work with grapes from A-graded vineyards across all of their ports, and their top wines are still trodden by foot. Since 2013 Krohn has been part of the Fladgate Partnership - alongside Taylor's, Fonseca and Croft.

Made from selected red ports produced from the best vineyards of the Douro Valley. Aged in small oak casks, typically of around 630 litres. As the wine ages it gradually loses the ruby red colour of its youth, becoming tawny in colour, more smooth and mellow on the palate, gaining richness and complexity.

There is no need to decant this port, and it can be enjoyed at room temperature, or served slightly chilled. Once open it will keep fresh for 2-3 months. Drink alongside toasted almonds, walnuts, dark chocolate and berries - or with blue-veined cheeses.
