Into a cocktail tin, over ice add Suntory Whisky Tori, Luxardo Sour Cherry Syrup, freshly squeezed lemon juice, and two dashes Angostura orange bitters.

Secure the lid of the cocktail tin and shake vigorously for 30 seconds.

Strain into a standard rocks glass filled with ice. Top off with guava soda. 

Express the oils from a heated wedge of lemon along the rim of the serving glass and toss the lemon into the cocktail.

Add a sprig of fresh French tarragon.

Serve.
