Welcome to St.Cousair Winery!

St.Cousair is an award-winning winery based in the town of Iizuna, in the northern part of Nagano Prefecture. Far from the crowded cities, yet easily accessible from them, it is a delightful place to visit and enjoy fine food and wine, while taking in the fresh air and beautiful mountain scenery that Nagano is known for.

Our winery is located on a picturesque hilltop surrounded by five prominent mountain peaks. Here, in addition to the winery, are two restaurants, our Flagship Store, a chapel, and our Jam and Sauce production facility.

Come and visit us and experience for yourself the fine cuisine, beautiful vistas, and relaxed lifestyle that we like to call “Country Comfort!”

About Our Winery

St.Cousair Winery produces over 20,000 cases (approximately 250,000 bottles) of wine and cider per year. Our estate vineyards are located in Iizuna-machi, in the northern Chikuma River Valley, a hilly region that is quickly becoming an outstanding wine production area in Japan.

Our Estate Ōiri Vineyard is one of the highest awarded vineyards in Nagano. The beautiful 8-hectare site, 5 kilometers from the winery, is 650 meters above sea level, on a downhill, south-facing slope. The vineyard’s elevation and substantial 50 cm winter snowfall provide the necessary moisture that leads to its spectacular June blossoms, and during the growing season, the grapes receive bountiful sunshine. The grapes produced at Ōiri are primarily Chardonnay, but we also grow Merlot, Pinot Noir and other varieties on the site.

Our Estate Chapel Vineyard, located on the hillside below the restaurant and chapel, consists of Cabernet Franc and Cabernet Sauvignon grapes. All our vineyards receive moderate rainfall and sufficiently dry winds, with an average growing season temperature of 20°C.

St.Cousair Winery has been the recipient of multiple awards, including:

Challenge International du Vin Gold Medal, Nagano Chardonnay 2015

Chardonnay du Monde Silver Medal, St.Cousair Chardonnay 2012

Challenge International du Vin Gold Medal, Zion 2011

Our Story

St.Cousair's roots trace back to the 1970s, when founder Ryozo Kuze and his wife Mayumi operated a ski lodge in Madarao Kōgen, near the present-day Iizuna-machi. Though the ski lodge was moderately successful, operating it was physically exhausting, and Ryozo and Mayumi soon decided to pursue a different path.

During the years operating the ski lodge, Mayumi often made homemade apple jam as a gift to their guests. Her apple jam became popular among repeat visitors, and was soon being sold in other ski lodges in Madarao Kōgen. Residents and tourists began asking Ryozo where his jam factory was located, even though there wasn’t a factory. But the idea had been planted and Ryozo now knew the path ahead of him. He and Mayumi closed the ski lodge for good, and devoted their efforts to building a jam factory, winery, restaurant and gift shop in the present-day town of Iizuna-machi.

What started as a simple recipe for apple jam, has since grown to over 100 retail shops and restaurants throughout Japan, and the company is currently expanding its production of fine food and beverages worldwide, through its retail brands, St.Cousair and Kuze Fuku & Co.

St.Cousair still espouses the simple, relaxed lifestyle that we often refer to as “Country Comfort.” The Winery in Iizuna today is a popular destination for tour groups, families and individuals interested in winery tourism, fine cuisine, fresh air, and breathtaking mountain views.
