Vintage port[edit]
Vintage port from 1870 and 1873
Vintage port is made entirely from the grapes of a declared vintage year and accounts for about two percent of overall port production. Not every year is declared a vintage in the Douro. The decision on whether to declare a vintage is made in the spring of the second year following the harvest. The decision to declare a vintage is made by each individual port house, often referred to as a "shipper".
The port industry is one where reputations are hard won and easily lost, so the decision is never taken lightly. During periods of recession and war, potential "declarations" have sometimes been missed for economic reasons. In recent years, some shippers have adopted the "chateau" principle for declarations, declaring all but the worst years. More conventional shippers will declare, on average, about three times a decade.
While it is by far the most renowned type of port, from a volume and revenue standpoint, vintage port actually makes up only a small percentage of the production of most shippers. Vintage ports may be aged in barrels for a maximum of two and a half years before bottling, and generally require another ten to forty years of ageing in the bottle before reaching what is considered a proper drinking age. Since they are potentially aged in barrels for only a short time, they retain their dark ruby colour and fresh fruit flavours. Particularly fine vintage ports can continue to gain complexity and drink wonderfully for many decades after they were bottled. It is not uncommon for 19th century bottles to still be in perfect condition for consumption
