Combine sugar and water
Combine sugar and water in a small saucepan over medium heat.
Dissolve the sugar
Stir until the sugar completely dissolves. Keep the heat moderate — a gentle simmer is all you need. Do not boil aggressively, which can make the syrup slightly cloudy.
Add thyme
Remove from heat and add the thyme sprigs, stems and all. The stems carry flavour too — no need to strip the leaves beforehand.
Steep
Steep for 20–30 minutes. Taste every 10 minutes — thyme builds gradually, and you're looking for a clean, herbal flavour without any harsh or medicinal edge.
Thyme is more forgiving than rosemary or lavender — it takes longer to over-extract. Still, pull the sprigs as soon as the flavour tastes right to you.
Strain
Strain through a fine mesh strainer into a clean glass bottle or jar. Press the spent sprigs gently to extract all the syrup.
Cool and refrigerate
Allow to cool to room temperature before sealing. Refrigerate and use within 3–4 weeks. Label with the date you made it.
Common thyme (Thymus vulgaris) is what this recipe is built around. Lemon thyme works identically but produces a noticeably brighter, more citrus-forward syrup that pairs exceptionally well with gin and sparkling drinks. See the Thyme Guide's variety section for a full comparison of garden thymes worth growing for the bar.
