Add 6 fresh thyme sprigs to the saucepan, reduce heat to low, and let the syrup steep for 10 minutes off the boil. Taste after 10 minutes — it should have a noticeable but balanced thyme aroma.

Remove from heat and allow the thyme to steep for an additional 10 minutes for extra herb flavor if desired (keep covered).

Strain the syrup through a fine mesh sieve into a clean jar or bottle, pressing lightly on the thyme to release trapped liquid. Discard thyme sprigs. Cool to room temperature, then refrigerate. Syrup will keep up to 2 weeks refrigerated.

Cocktail Assembly

Chill glass: place a highball or Collins glass in the freezer for a few minutes or fill with ice and water to chill while you prepare the cocktail.

Build the drink: fill a cocktail shaker with ice. Add 2 oz Botanist Gin, 0.75 oz fresh lemon juice, and 0.75 oz thyme-infused simple syrup.

Shake vigorously for about 10–12 seconds until well chilled and slightly diluted.

Prepare the glass: discard ice/water if you used it to chill, then fill the chilled glass with fresh ice (cubed or crushed to preference).

Double-strain the shaken mixture into the prepared glass over fresh ice to remove any small ice shards and herb bits.

Top with a 2 oz splash of soda water. Stir gently once to marry the soda with the cocktail without losing too much effervescence.

Garnish with a fresh thyme sprig and a lemon wheel or twist. Optionally clap the thyme between your hands near the glass to release aromatic oils before placing it on top.

Serve immediately.
