A Touriga Nacional-based blend of traditional Douro red varieties, grown on schist-sandstone soils at 600 meters of elevation.
Tawny wines are aged oxidatively in barrel, and typically blend multiple vintages together to achieve the desired age character. Colheitas, on the other hand, are tawny wines made from a single harvest. Kopke ages their Colheitas in oak barrels for periods of time that can vary, but never less than 7 years. They are bottled from cask as the market dictates.
