Square Root Lemonade is built on fresh Sicilian lemon juice, British beet sugar, and sparkling water. No concentrates, no artificial flavouring, no sweeteners. It's a short ingredient list done well. In the glass it's clear and pale yellow, with fine carbonation. The nose is bright and direct: fresh lemon peel and clean citrus. On the palate, tartness leads, followed by a moderate sweetness that doesn't linger. The finish is clean. It's sharper and less cloying than most supermarket lemonades, which are typically built around sugar and citric acid rather than actual lemon juice. Vegan, gluten-free, around 100 calories per 275ml bottle.
