Product description

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 30°C (57 -86°F), 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 - 25°C (68 -77°F) range and the pH is above 3.0.
