Temperature really matters. Keep your bubbles between 46 degrees F and 54 degrees F.
An ice bucket (with water) is a great way to bring a bottle down to temperature quickly, and if you add a handful of salt in your ice water it will stay cooler for longer.
Although the pop of a cork sounds great, it is preferable to gently ease it out with a slow twisting motion. Only take the metal cage off when you are ready to open the bottle – it is there for a reason.
A flute is the classic glass for bubbles. While a flute or a coupe (its shape dubiously said to have been inspired by Marie Antoinette’s bosom) might look good, the better glass, is curved and tall. Fill it less than halfway and it will capture the aromas in the neck of the glass for a sublime tasting experience.
