A highly aromatic strain suitable for white & rosé  wines, this moderate fermenting yeast confers fragrant aromatics esters to the wine which enhance varietal expression and aroma. This positive aromatic impact can be used to complete the natural aromatic qualities of the grape, or to enhance where the grape itself is lacking.

Suitable for Riesling, Gewurztraminer and more.

Alcohol Tolerance: 14% ABV

Usage Directions: No rehydration required - add direct to grape must and stir well. For best results, ferment at 16 - 24°C (61 - 75°F).

Storage Recommendations: Store in a cool, dry place.

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.
