This is a bright, green, garden-forward tonic built from tarragon, basil, and lemongrass—carbonated to service pressure in a siphon. It’s designed for speed (blend-strain-filter-charge), clarity (fine strain + coffee filter), and stability (cold extraction + low oxygen). Below you’ll find why it works, how to nail it every time, and how to use it across cocktails, low-ABV, and zero-proof serves.
