Agiorgitiko, Greece’s second most widely planted grape, is the only one allowed in Nemea, an appellation on the Peloponnese, west of Athens. Although the grape often is transformed into bold, age-worthy red wines with considerable complexity, this one is a bit lighter, delivering red cherry-like flavors and an appealing rusticity. Bright acidity keeps it lively. Not a fruit bomb, it’s a good match for hamburgers and such on the grill.
