Lalvin QA23 – 5g Sachet

R2,909.00 incl. VAT

Lalvin QA23™ was selected in Portugal by the University of Tras os Montes e Alto Douro (UTAD) in cooperation with Viticultural Commission of Vinhos Verdes region.

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.

Grape variety pairing
Sauvignon Blanc, Chenin Blanc, Colombard, Gewürztraminer, Muscadelle, Pinot Gris, Riesling, Semillon, Viognier and Roussanne.

Wine Styles
Varietal aromatic white wines. Useful for a wide range of applications, including mead and fruit cider fermentations.
