Bull's Milk

Pro tips

• Heat the milk gently before adding spirits to prevent curdling and enhance smoothness.
• Dissolve powdered sugar fully in the spirits before combining with milk.
• Use aged rum and brandy—the quality of base spirits directly impacts the final drink.
• Strain through fine mesh if any curdling occurs for a silky finish.

Substitutions

• Old Mr. Boston Rum → quality aged dark rum (similar proof and depth)
• Old Mr. Boston Five Star Brandy → cognac or VS brandy (richer flavor profile)
• Powdered Sugar → simple syrup, 1 tsp (dissolves faster, prevents grittiness)

Storage & make-ahead

Best served immediately after preparation. Store unmixed spirits separately; combine with fresh milk just before serving.

Can I make Bull's Milk without brandy?

Brandy is a key ingredient for flavor balance. Whiskey could substitute in equal measure, though it will change the character.

Should Bull's Milk be served hot or cold?

Traditionally served hot, though it can be served over ice. Heat enhances the spirit flavors and creates a warming drink.

Can I batch this cocktail ahead?

Mix the spirits and sugar in advance, but add milk just before serving to prevent curdling.

What type of milk works best?

Whole milk delivers the richest, creamiest texture. Non-dairy milk (oat, almond) can work but may curdle with aged spirits.
