Perlage

Perlage refers to the bubbles in a sparkling drink. Size, fineness, quantity and duration of the beads are assessed. In sparkling wine and champagne a fine, lasting perlage is considered high quality because it points to good processing and the right gas pressure.

It is influenced by production, the glass, its cleanliness and the temperature. Grease residue or detergent destroy the bubbles. A clean, dry glass or slightly roughened spots at the base promote their formation. Perlage also shapes mouthfeel, such as whether a drink tingles creamily or coarsely.
