In 2001, a small, unassuming cooperative winery nestled within a residential area in Yamanashi City, complete with licenses and equipment, was up for sale. It was then taken over by the Suzuki couple, who started the new Asahi Western Liquor the following year.

The first year of brewing was done entirely with purchased grapes, but the initial fermentation of Koshu grapes in barrels won a popularity vote among Yamanashi Prefecture wine enthusiasts held in 2003. In 2004, it was featured in the "World Wine Report 2004" published in the UK, which highlighted that 'an 80-year-old cooperative winemaking facility was revived by a young couple's winemaking team.'

 Also, in the special edition of Wine Kingdom called "Japanese Wine Archipelago", the 2003 Soleil Koshu was selected as one of the 36 specially chosen domestic wines.

Since then, the winery has consistently made good wine from healthy grapes, earning positive evaluations from customers, among others.

Starting in 2018, at the 'Japan Winery Award', they gained an additional star in 2020, achieving a four-star rating, which is the second-highest level in the five-star system.
