Lalvin QA23 is a highly aromatic wine yeast selected in Portugal and widely used for producing fresh, vibrant white wines. It is especially well suited for varietals where aroma preservation and expression are key, delivering bright citrus, tropical fruit, and floral notes.

QA23 ferments cleanly and efficiently at cool to moderate temperatures, making it an excellent choice for aromatic whites, rosés, and light-bodied wines. It produces low volatile acidity, maintains varietal character, and helps create wines with a crisp, refreshing mouthfeel.

This yeast is easy to use, reliable, and a favourite among both home winemakers and professionals.
