Verjus Espresso Sour

1. Prepare the Glass

Place your coupe glass in the freezer or fill it with ice water to chill while you build the cocktail.

2. Combine and Shake

1. Add the verjus, fresh espresso, simple syrup, aromatic bitters, and egg white (or aquafaba) into a cocktail shaker without ice.
2. Seal tightly and shake vigorously for 10 seconds to emulsify the foam.
3. Open the shaker, fill it generously with ice cubes, reseal, and shake hard again for about 15 seconds until thoroughly chilled and frothy.

3. Strain and Serve

1. Discard any chilling ice from your coupe glass.
2. Double strain the mixture through a fine-mesh strainer into the coupe to achieve a clean, silky texture with a thick head of crema.
3. Gently float the coffee beans on the foam and serve immediately.
