In the four years since it started, Festivin has grown from an intimate gathering of natural wine enthusiasts to one of the most eagerly anticipated wine celebrations in Japan.

Like many avant-garde movements in the food and beverage world, the idea for Festivin began at a party, when Shinsaku Katsuyama, one of the early pioneers in the Japanese natural wine scene and owner of wine bar Shonzui in the capital's Roppongi district, suggested that a group of importers, shop owners and journalists join forces to host a natural wine event. Approximately 2,200 people attended the third edition of Festivin in 2012, more than double the attendance of the first event, and the turnout is expected to rise when the fair returns to Tokyo on Nov. 30 for its fourth edition.

Part of what attracts so many people to the event is the fact that there's something new to look forward to every time. Along with food and musical performances, Festivin 2014 will feature more than 300 natural wines from producers in Japan and around the world. This year's lineup includes eight winemakers from the former Soviet republic of Georgia, who will be pouring a selection of unique wines fermented in large, egg-shaped clay vessels called kvevri.
