Rhine Wine Cup

Pro tips

• Dissolve powdered sugar thoroughly in the brandy and triple sec before adding carbonated water to avoid grittiness.
• Use well-chilled carbonated water and serve the finished drink immediately to maximize fizz and effervescence.
• Chill your glassware beforehand to keep the drink cold longer without over-diluting with ice.
• Measure ingredients precisely—this drink's balance depends on the sugar-to-spirit ratio.

Substitutions

• Old Mr. Boston Triple Sec → Cointreau (higher quality, slightly drier finish)
• Old Mr. Boston Five Star Brandy → Cognac or VS brandy (richer, more complex)
• Powdered Sugar → Simple syrup, 1/2 oz (easier to mix, slightly smoother)
• Carbonated Water → Champagne or sparkling wine (more luxurious version)

Storage & make-ahead

Rhine Wine Cup is meant to be consumed immediately after preparation; do not store the mixed cocktail as carbonation will be lost.

Can I make Rhine Wine Cup ahead of time?

Mix the brandy, triple sec, and powdered sugar in advance, but add carbonated water immediately before serving to preserve carbonation.

What's the difference between Rhine Wine Cup and other wine punches?

Rhine Wine Cup uses brandy and triple sec as its base spirits rather than wine, making it richer and more spirit-forward than traditional wine punches.

How should Rhine Wine Cup be served?

Serve chilled over ice in a wine glass or punch cup. The carbonation is essential to the drink's character.

Can I scale this recipe for a crowd?

Yes—multiply all ingredients proportionally. For large batches, keep the base spirits and sugar mixed separately, then add carbonated water just before serving.

What type of brandy works best?

Old Mr. Boston Five Star Brandy is traditional, but any affordable, smooth brandy between 80–90 proof will work.
