Of the hundreds of different sweet wines produced in Italy, the best known may be vin santo, “holy wine,” so named because priests have drunk it during the Mass for centuries. Vin santo is the customary finale to even the humblest Tuscan meal, served after espresso, almost always with a plate of small biscotti called cantucci, stubby, twice-baked cookies meant for dunking. Most vin santo does not taste as sweet as, say, Sauternes. The wine has a delicate, creamy, honey-roasted flavor, and the color can be unreal, from radiant amber to neon orange.
