In 2009, Koyama Wines Limited was established. Grapes for Koyama Wines came from three local growers’ vineyards namely Williams’ (Pinot Noir), Pearson’s (Pinot Noir) and Tussock Terrace (Riesling).
In 2017 with investment from Japan, Koyama Wines Limited purchased Mountford Estate and now all Koyama wines are produced at Mountford except for Riesling Sparkling Brut and Brut Nature which were added to the list in 2018.
