According to Federico Lleonart, Global Wine Ambassador for Spain & Argentina at Pernod Ricard, the Group that owns top Champagne houses G.H. Mumm and Perrier-Jouët, champagne is best served from a simple white wine glass.
Lleonart clarifies that the white wine glass is the best option for champagnes, characterized by complexity, depth and autolytic notes, in order to let the aromas express themselves better.
However simple sparkling wine should still be served in a flute, because it keeps the drink colder for longer and makes the bubbles look nicer.
When comparing the flute to the once popular coupe Lleonart explains that the flute concentrates carbon dioxide at the top of the glass, whereas the saucer’s wide mouth means the bubbles evaporate more quickly.
