Single Harvest Ports are wines of a single year which have been aged in seasoned oak casks. They display the date of the harvest on the label. These wonderfully mellow complex wines have been aged to full maturity and are ready to drink when bottled.
Every year, Taylor’s makes a limited release of a Single Harvest Port made 50 years previously. These are the perfect wines with which to celebrate a 50th anniversary or birthday and are presented in attractive wooden gift boxes.
94 points Robert Parker's Wine Advocate, The 1966 Single Harvest Tawny Port (i.e., a Colheita) is a traditional blend, aged in French and American oak. It comes in at 183 grams per liter of residual sugar. Surprisingly rich and fresh, this seems younger than its age. The complexity here is not quite as great as with some and the nuances of molasses and the like are controlled. On the other side of the coin, it has a rather sensual texture, finishing with a sugary burst. Underneath is the expected acidity and a bit of pop. Overall, it is rather seductive and quite delicious. Note that this will be released in January 2016, part of Taylor's old Colheita releases.
These all come with a bar top cork, i.e., you can hold them indefinitely if you wish, barring cork problems, but they are not really intended to be aged. They, like pretty much all Tawnies, are considered ready to drink on release.
