Pour the Amer Picon and grenadine into a Georgian Irish Coffee glass over ice and stir briefly.
Fill almost to top with the soda water.
Float the brandy on top.
Garnish with a lemon peel.
*Amer Picon: Because it’s not available in the U.S., as a substitute, combine 2 parts Ramazzotti amaro, 2 parts dry curaçao and 1 part gentian liqueur in an airtight bottle and shake. Refrigerate until ready to use.
