Perlage
/per-LAHZH/The quality and behavior of bubbles in sparkling wine.
Full Definition
Perlage describes the bubbles in sparkling wine - their size, quantity, persistence, and movement. Fine perlage features tiny, numerous, persistent bubbles rising in steady streams (trains). Coarse perlage has larger, fewer, quicker-dissipating bubbles. Quality correlates with production method and aging time on lees.
