AW4 Wine Yeast

New RRP 13th January 2025 $6.50.

Saccharomyces Cerevisiae - The 'only strain' for Germanic aromatic white wines.

AW4 is noted for developing powerfully fragrant, full spice aromatic wines and is a perfect match for Gewurztraminer and also recommended for Sauvignon and Semillon where the Oenologist requires a positive aromatic esters contribution from the yeast.

AW4 is a good fermenter across the range 14 to 30°C, low foam formation and medium to high glycerol. It will ferment up to 14% abv. ethanol providing the temperature is held within the 20 - 25°C range and the pH is above 3.0.
