Krohn 1976 Colheita Port is a single vintage Tawny Port. A Colheita Port must be made from grapes harvested from a single vintage and aged for at least 7 years in barrel prior to release. Wiese and Krohn was founded in 1865 by two young Norwegians, Theodor Wiese Dankert Krohn. Edmundo Falcão Carneiro acquired the company in the 1930s and Wiese and Krohn was run by the second and third generations of the Falcão Carneiro family until 2013. Krohn Port was acquired by the Fladgate Partnership (owners of Taylor, Croft and Fonseca) in 2013. Krohn's stocks of Port reach over 5 million litres and are stored in six cellars in Vila Nova de Gaia and one cellar in the Douro Region. They have exceptional stocks of aged tawny Port and colheita Port dating back to 1863. Grapes for this Port are sourced from old vine vineyards at Krohns famous Quinta do Retiro estate and from neighbouring growers in the Rio Torto Valley. The grapes are trodden by foot in large granite "lagares" where the wine also undergoes fermentation. Fermentation is stopped with the addition of grape spirit when the desired level of sweetness is acheived. Krohn 1976 Colheita Port is a blend of Tinta Roriz, Touriga Nacional and Touriga Franca and is aged in 547 litre oak barrels (also traditionally known as a Port pipe). Presented in a wooden gift box. The current bottling was bottled in 2015.
