Do smaller bubbles mean better Champagne...?

Champagne bubble size – does it matter?

Tyson Stelzer, Decanter expert and author of The Champagne Guide 2016, replies:

Yes, smaller bubbles are an indicator of quality. The méthode traditionnelle process through which all Champagne and the finest sparkling wines are produced creates the bubbles during the second fermentation in the bottle.

The fewer impurities in the still wine and the cooler the cellar in which this fermentation occurs, the smaller the bubbles.

Tiny bubbles are easy to discern in the mouth as they produce a finer bead than the larger bubbles created by coarse juice, fast fermentation or carbonation.

While it is possible to appreciate smaller bubbles in the glass, I never judge the bead in this manner since the rate at which it is released is highly dependent upon the temperature and the inside surface of the glass.
