Lalvin QA23™ has a very high β-glucosidase activity, an enzyme which helps to cleave non-volatile aromatic compounds into their volatile state. Hence this yeast contributes to varietal / terroir fruit expression.

Its use for Sauvignon Blanc is therefore highly recommended. Known for its reliability and robustness, Lalvin QA23™ tends to ferment well in clarified juice, low in nutrients.
