Details
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 ester contribution from the yeast. AW4 is a good fermenter across the range of 14 to 30C (57-86F), low foam formation and medium to high glycerol. It will ferment up to 14.5% abv. ethanol providing the temperature is held within the 20-25C (68-77F) range and the pH is above 3.0.
