VINTNER'S HARVEST YEAST - AW4

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 30ºC (57-86ºF), 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 (68-77ºF) range and the pH is above 3.0.
