Bull's Milk

Pro tips

• Dissolve powdered sugar completely in the rum before adding brandy and milk to avoid grittiness.
• Chill all ingredients beforehand; cold components prevent milk from curdling.
• Shake gently with ice rather than vigorously to preserve the creamy texture.
• Strain into a chilled glass to maintain the smooth, silky mouthfeel.

Substitutions

• Old Mr. Boston Imported Rum → any aged light or dark rum (adjust sweetness to taste)
• Old Mr. Boston Five Star Brandy → cognac or other quality brandy (note: may shift flavor profile)
• Powdered Sugar → superfine sugar (dissolve thoroughly before mixing)
• Whole Milk → heavy cream mixed with milk for richer texture, or evaporated milk for shelf stability

Storage & make-ahead

Best consumed immediately after preparation. Pre-mixed spirit blend stores in a sealed bottle for up to 2 weeks; add milk fresh before serving.

Should Bull's Milk be served hot or cold?

Traditionally served chilled or over ice. Some variations are served warm, but the classic preparation is cold.

Can I make Bull's Milk without brandy?

Yes, you can substitute additional rum or use whiskey, though the brandy contributes a distinct smoothness to the drink.

How do I prevent curdling in a milk-based cocktail?

Use fresh milk, avoid overheating, and ensure spirits are at room temperature or chilled—not hot—before mixing.

Can Bull's Milk be made in advance?

Mix spirits and sugar ahead, but add milk just before serving to prevent separation and maintain texture.
