Rule 2: Use three ice cubes
Just because you can pour this wine over ice doesn’t mean you should fill your glass to the brim to create a murky champagne slushy. Three large cubes is the ideal amount to get the right ratio of water to wine. Your first sip will be fruity and intense, but you’ll get a more balanced flavor as the ice begins to melt (slowly enough to avoid immediately flushing your glass with excess water -- a little sacrilege is fine, but criminality is not).
Rule 3: Go ahead and garnish
Moët Ice Imperial naturally has notes of fruit that can be enhanced further by the flavors released through garnishes like mint leaves or lemon peels, while other champagnes might be overwhelmed. Throw in some raspberries, strawberries, or a slice of lemon and those flavors will make for some seriously aromatic summertime freshness.
Rule 4: Mix it in a cocktail
In most classic cocktails, champagne is really just used to add a bit of effervescence. But with a champagne like Moët Ice Imperial, where the flavors are strong enough to withstand a bit of dilution, the wine takes on a more central role. For example, if you’re drinking a French 75, the spirit and acidity will usually overpower the champagne -- but Moët Ice Imperial is bold enough to elegantly push back. And cocktails at brunch only get better too, now that they have the ability to withstand dilution from a few ice cubes. Finally, you won't have to worry about your drink getting warm/gross when you opt to sit outside.
