Founded in 1959 by the Cálem family, this wine-production company was taken over by a bank based in Vigo, Spain, in 2001. Its tour is much less formal than one at Sandeman, next door. A tour hostess will guide you through the barrel-making process, leading you past 75-year-old oaken casks, each laid out in an antique stone-sided warehouse whose walls are marked with the high-water marks of each of the floods of the past 200 years. The tour eventually heads upstairs to an antique room whose displays of port evoke the great days of the wine trade at its best. The cellars are a bit newer than those at the more established firms, but the port, depending on the vintage, is just as good.
