In 2013, the world of wine continued to diversify. Though the classics stand tall, including Bordeaux, Napa Valley Cabernet Sauvignon and Tuscan wines, ever more esoteric and emerging categories share the spotlight. As always, we at Wine Spectator applied our standard criteria in selecting this year's 100 stars from among the more than 20,000 newly released wines we reviewed in blind tastings in 2013. But although quality (based on score), value (based on price) and availability (based on the number of cases either made or imported into the United States) remain critical, we gave extra emphasis to what we call the "X-factor"—the intensity of interest the wines excited by way of their singularity or authenticity. These 100 selections represent the producers and wines our editors were particularly passionate about in 2013.
