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.

It will ferment up to 14.5% abv. ethanol providing the temperature is held within the 20 - 25 °C (68 -77 °F) range and the pH is above 3.0.
