Koshu Wine Nouveau
甲州ワインヌーボーEach November, the wine region of Katsunuma and the wider Kofu Basin celebrate the release of the year's new vintage with a series of tastings, festivals, and winery events that constitute Japan's most joyful expression of viticultural identity. The Koshu Wine Nouveau, modeled in spirit though not in style on the Beaujolais Nouveau tradition, marks the moment when the current year's Koshu and Muscat Bailey A grapes, harvested weeks earlier from the sun-warmed hillsides of Yamanashi, are tasted for the first time as finished wine. The release is both a celebration and a reckoning, a public moment when the year's weather, the winemaker's decisions, and the vine's own vitality are revealed in the glass.
The nouveau wines are light, fresh, and immediate, designed for pleasure rather than contemplation, and their release generates an atmosphere of communal enthusiasm that fills the winery tasting rooms and festival venues of Katsunuma with an energy rarely associated with Japanese wine culture. The event has grown from a local observance to a regional celebration that draws visitors from Tokyo and beyond, driven by the increasing recognition of Koshu as a serious wine grape and by the simple appeal of drinking young wine in the landscape where the grapes were grown.
The timing aligns with the autumn beauty of the Kofu Basin, when the vineyard leaves turn gold and amber, the persimmon trees hang heavy with orange fruit, and the mountain ring surrounding the valley displays the full spectrum of autumn foliage. This convergence of sensory pleasures, the taste of new wine, the sight of harvest landscape, the crisp November air, creates an experience that transcends wine appreciation and becomes an immersion in the season itself.

History & Significance
The Koshu Wine Nouveau tradition emerged in the early 2000s as part of a broader effort by Yamanashi's wine producers to build public awareness and appreciation for domestic wine. Japanese wine had long occupied a marginal position in the national consciousness, overshadowed by imported European and New World wines, and the nouveau release provided a focal point for a narrative of quality, place, and cultural identity that the region's winemakers were eager to establish. The choice of November, echoing the Beaujolais Nouveau release, was deliberate, positioning Japanese wine within the global calendar of viticultural celebration while asserting Yamanashi's distinctiveness.
The success of the nouveau release has paralleled the broader ascent of Koshu wine in international recognition. The 2010s saw Koshu wines earn medals at the Decanter World Wine Awards and gain listings at leading restaurants in London, Paris, and New York, developments that lent the November celebration an air of vindication. What had begun as a local marketing initiative became a genuine expression of pride in a wine tradition whose quality had arrived at a level that the international community could no longer overlook.
What to Expect
The nouveau release is celebrated at individual wineries throughout Katsunuma and at organized festival events in Kofu and surrounding communities. Many wineries host open days with tastings of the new vintage alongside older releases, providing context for the nouveau wines and demonstrating the range of which Koshu and the region's other varieties are capable. The atmosphere at these winery events is informal and convivial, with winemakers pouring personally and engaging visitors in conversations about the vintage, the growing season, and the future direction of their craft.
The flagship festival events, held on designated release weekends at venues in Kofu and at the Budo no Oka wine facility in Katsunuma, concentrate dozens of producers in a single location, allowing visitors to taste broadly and compare styles. Live music, food pairings, and the festive energy of a community celebrating its annual harvest create an experience that is as much about social connection as about wine. The food offerings at these events emphasize local pairings: Koshu wine with sashimi, with tempura, with the seasonal produce of the basin.
For visitors interested in deeper engagement, several wineries offer harvest-season experiences including vineyard walks, winemaking demonstrations, and blending workshops that provide hands-on understanding of the process that produces the wine in the glass. These experiences are typically available by reservation and offer a level of access to the winemaking process that is rarely available outside the growing region.
