Very versatile yeast of American origin for the production of American and English ales (e.g. APA, IPA, Imperial / Double IPA, Imperial Stout, Imperial Porter, Brown Ale, American Barley Wine etc.). It has an excellent fermentation capacity, a high fermentation speed and a medium flocculation. FERMOALE AY4 develops a neutral and pure aroma profile with very low diacetyl values.
Delivers light malty flavour notes with a touch of citrus. Esters are mild to give a balanced and clean, neutral finish.
