Nose
Sparkling wine and citrus rise first, with fruit garnish broadening the aroma into something more festive than austere.
Palate
This sits between sour, cup, and celebratory sparkler. The sugar-and-citrus base gives it sour lineage, but the fruit and champagne push it into a more decorative social role.
Finish
The finish is bright, sparkling, and fruit-lifted.
Summary
A celebratory sparkling sour with visible banquet-glass hospitality.

The Champagne Sour is historically useful because it shows the sour family extending into sparkling luxury service rather than only into stripped acid-spirit forms.

The champagne should be added slowly. Johnson is after elegance and intact sparkle, not foam and waste.

  1. Fill a medium bar glass three-quarters full of shaved ice.
  2. Add the lemon juice, fill with champagne, stir gently, dress with fruit and berries, dash with brandy, and serve with straws.

Garnish: Fruit and berries

Ice: Shaved ice

This matters because Bullock preserves the sparkling sour branch in a dressed bar-glass form rather than only compact stemmed formats.

The gentle stir and final brandy dash are part of the service identity and should not be flattened into a generic fizz.
