Lalvin QA23™ For complex Sauvignon Blanc 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.
Alcohol tolerance of up to 16% v/v (depending
on fermentation conditions)
Fermentation temperature: 14-28°C (57-82°F)
Recommended dosage : 5g/20-30L
