Stout Whiskey Sour

Chill a double Old Fashioned glass in advance to ensure optimal serving temperature.

Combine the Irish whiskey, freshly squeezed lemon juice, rich sugar syrup, and saline solution in a shaker filled with ice.

Shake the mixture vigorously to blend the flavors thoroughly.

Strain the mixture into the pre-chilled glass filled with fresh ice.

Gently float the chilled stout beer on top of the cocktail.

Serve the cocktail without garnish for an elegantly simple presentation.
