Indicazione Geografica Tipica, or IGT, is a category of appellation control introduced in Italy in 1992 that dwells below DOC and within—and at the highest level of—VdT, or Vino da Tavola (table wines). Its purpose is to accommodate wines from defined geographical areas made using grape varieties or proportions not approved by the more prestigious DOC or DOCG categories. Many high-quality producers in regions such as Tuscany and Piedmont prefer this category to VdT for their wines made from nontraditional varieties (such as Cabernet Sauvignon and Chardonnay) because, unlike VdT wines, IGT wines may indicate place of origin, vintage, and grape variety.
