I've sorta done a study on this theory for a while. Port happens to be one of my favorite types of wines, the pairing with deserts can be fantastic. I've tried all kinds of ports from all over the world, and good buddy of mine who's a serious wine collector has even shared a few bottles of port in the triple digit price range, some bottles were older then I am... I've even gone out of my way when traveling on business to try local expensive port wines but you know what I found after all these years and all those ports?.... the best one I've ever had wasn't over $100, instead, it is a superb tawny that believe or not... costs $2.99! (and its made locally)
Name names!
