Following years of extensive commercial winemaking trials by Dr Toni Cordente at The Australian Wine Research Institute funded by Wine Australia, the best grape varieties suitable for this yeast appear to be white varietals when there is a need for a strong contribution from the yeast. Pinot Gris, Riesling, Chardonnay, Colombard and Semillon are well suited. AWRI Rosa has been trialled on red grape varietals such as Grenache and Shiraz, however red fruit and berry notes were masked when using this yeast, suggesting that this yeast is more suitable for white grape varietals.
