Why This Works
This is a drink that proves how far a single ingredient can go. Bitters are concentrated botanical complexity, and a half ounce of a good alcohol-free bitters turns plain soda into something aromatic, dry, and grown-up. It is the digestif of the alcohol-free world: light, palate-cleansing, and quietly sophisticated.
The whole trick is quality and cold. Use a bitters you genuinely like, keep the soda ice-cold for maximum carbonation, and let the citrus twist do the finishing work with its expressed oils. There is nothing to hide behind, which is exactly what makes a well-made one so satisfying.
The Alcohol-Free Swap
Alcohol-free bitters, like those from All The Bitter, are the unsung heroes of the AF bar. Used generously rather than by the dash, they can carry a whole drink.
