Crafting the ideal gin and tonic starts with chilling your glass completely. Fill a Copa de Balon glass with large, crystal-clear ice cubes to ensure minimal dilution.
Pour fifty milliliters of Imperial Silver London Dry Gin over the ice, allowing the botanical notes to gently open up before adding the mixer.
Top with one hundred and fifty milliliters of premium Indian tonic water, pouring it gently down a bar spoon to preserve the delicate effervescence.
Garnish with a fresh slice of pink grapefruit and a sprig of rosemary to accentuate the crisp juniper and citrus core of this exceptional gin.
