Which cocktail typically served in a champagne glass includes a sugar cube and a lemon twist garnish?

The cocktail that is typically served in a champagne glass and includes a sugar cube along with a lemon twist garnish is the Champagne Cocktail. This drink is a classic that highlights the effervescence of champagne paired with a hint of sweetness.

To make a Champagne Cocktail, a sugar cube is usually soaked in a few dashes of Angostura bitters, placed at the bottom of the glass, and then topped with chilled champagne. The lemon twist garnish adds a citrusy aroma that complements the drink beautifully. The result is a refreshing beverage that maintains the elegance and celebratory nature often associated with champagne.

The other options, while interesting in their own right, do not fit the description given. The Muddled Old Fashioned is typically served in a rocks glass and is characterized by its whiskey base, muddled sugar, and bitters, lacking the sparkling aspect of champagne. The Kentucky Mule is a variation of the Moscow Mule typically served in a copper mug, utilizing bourbon instead of vodka, and doesn’t utilize champagne. Lastly, the Grasshopper is a creamy cocktail made with crème de menthe, crème de cacao, and cream, served in a different style of glass, making it quite distinct from the Champagne Cocktail.
