Free AF's Rum & Ginger is part of the brand's range of canned AF cocktails, all built around Afterglow — their New Zealand-sourced botanical extract that's meant to mimic the physical warmth of alcohol. In practice, it does add something: a mild tingle that sets this apart from a standard ginger ale. The drink is unambiguously ginger-led. The extract gives it genuine heat — reviewers have called it the spiciest AF drink they've tried — with a vanilla note underneath and a citrus edge from the lime. The rum character is faint. If you're expecting something that reads convincingly like a rum cocktail, you may be disappointed; if you want a quality spiced ginger drink with a bit of edge to it, this delivers. At 27 calories per 100ml it's reasonably low, and it's listed as vegan and gluten-free. The 250ml can format makes it easy to grab for a single serve.
