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 30ºC, low foam formation and medium to high glycerol.
It will ferment up to 14.5% abv. ethanol providing the temperature is held within the 20 – 25ºC range and the pH is above 3.0.
