Things You'll Need:
- Champagne flute
- Bottle of champagne
-
Step 1
Pour chilled champagne into a champagne flute. A flute works best for this test of quality instead of a saucer-type champagne glass.
-
Step 2
Examine the size of the bubbles in the glass. Bubbles from a fine champagne whose effervescence is due to fermentation are pinpoint and very small. Bubbles from a lesser-quality wine are larger and reminiscent of soda bubbles, as they are a result of carbonation with carbon-dioxide.
-
Step 3
Observe the activity of the bubbles in your champagne flute. Better champagnes form intricate trails of bubbles from the bottom or sides of the glass to the top. Lesser-quality champagnes form bubbles that tend to cling to the sides of the glass rather than forming trails.
