The spicy margarita has become one of the more popular RTD formats in the non-alcoholic space, and Waitrose has taken the format into its own-label range. The approach here is straightforward: lime juice, some agave-style sweetness, chilli heat, and a hint of salt, all in a can. The chilli builds gradually rather than hitting immediately. Lime is upfront, the agave sweetness rounds the middle, and the jalapeño warmth arrives on the finish. It's a convincing enough replica of the structure even without the tequila backbone, and the heat is present without being aggressive. The carbonation keeps it from feeling still and flat. If you're after a non-alcoholic drink that has some genuine flavour interest rather than just sweetness, this delivers. The heat element is probably its best quality. Serve over ice.
