"Most port-wine houses offer tours of their cellars. The tour guides teach you to distinguish between tawny, ruby, late-bottled vintage, and vintage port. They also regale you with interesting stories and facts about port-wine production. You’ll learn, for example, that the “share of the angels” is the fraction of the wine stored that is lost to evaporation. At the end of the tour you are invited to a port-wine tasting, so you’ll also get a share of this precious nectar.
Sandman’s and Taylor’s are two of the most popular cellars to visit."
