The yeasts offered by AEB are the result of rigorous selections made in collaboration with prestigious Research Institutes. Perlage BN is a strain selected in the Champagne territory, indicated for the base fermentation of red grapes vinified both in white and rosé, particularly for Pinot Noir. Its main characteristic is to soften the sharp edges felt in the mouth when tasting, caused by the tannin component of these grapes. The wines obtained are softer and warmer, they display fresh and lightly sulphured notes at the nose, that in the sparkling wine will evolve into sweet notes with light toasted hints, persistent in the aftertaste.
