Bull's Milk

Pro tips

• Shake vigorously with ice for 10-15 seconds to chill thoroughly and create a smooth emulsion between spirits and milk.
• Use whole milk rather than reduced-fat varieties for richer texture and better mouthfeel.
• Dissolve powdered sugar in a small amount of rum before adding milk to prevent lumps.
• Chill your glass beforehand to keep the drink cold longer and prevent milk curdling from temperature shock.

Substitutions

• Old Mr. Boston Imported Rum → any aged Caribbean or light rum (maintains spirit balance)
• Old Mr. Boston Five Star Brandy → cognac or other premium brandy (deepens complexity)
• Whole Milk → heavy cream (creates richer, more indulgent version, reduce quantity)

Storage & make-ahead

Serve immediately after mixing. Do not store; milk-based cocktails curdle when left standing.

Can I make Bull's Milk with different spirits?

Yes. Substitute with other aged rums and brandies of similar proof, though the original spirit combination defines the classic flavor profile.

Should Bull's Milk be served hot or cold?

Traditionally served cold, either shaken with ice or blended. Some variations are served warm.

How long does Bull's Milk stay fresh?

Consume immediately after mixing. Milk-based cocktails don't store well and may curdle if left standing.

What's the difference between powdered sugar and regular sugar in this drink?

Powdered sugar dissolves instantly in cold liquid without grittiness, creating a smoother, creamier texture than granulated sugar.

Can I make a large batch for a party?

Not recommended. Milk-based cocktails curdle when stored. Mix individual drinks fresh to order.
