Fortified wines are among the wine world's great bargains. They make excellent presents and it's worth pointing out here that the rare Terrantez Madeira and the Pedro Ximénez (aka PX) can be kept for months once opened (although the need may well not arise...). I have also included, below the four fortifieds, a gem of a Canadian Ice Wine. It, too, is a bargain. The fortifieds are listed in ascending order of sweetness, starting with a dry sherry. Watch out for last-order date
