Ports fall generally into two categories: ruby and tawny. Ruby ports are primarily bottle-aged and usually feature fresh fruit flavors and spice. Vintage ports are the greatest rubies, and typically require many decades to reach maturity.
Tawnies, by contrast, see extended aging in wood barrels, which gives them more up-front appeal and more dried fruit and nutty flavors. Winemakers bottle them as 10, 20, 30, or 40 year old wines, although the number represents the average age of the wines in the blend, rather than a specific vintage of that age.
So-called "colheita" ports are essentially a blend of both styles, with the wine being vintage-dated but raised in wood barrels.
The Quinta da Boeira is basically everything you could want in a tawny port, with dark cherry, nuts, honey, and spice notes all chiming in. It is worth noting the curb appeal of the packaging. It would be nice to set aside a bottle of this for enjoying over the holidays. Of course it would also make a very fine gift.
For the gentleman. 40% Touriga Nacional, 30% Touriga Francesca, 30% Tinta Roriz. Serve cool in little glasses.
