What distinguishes a craft soda from an industrial soft drink?
The distinction is most visible in the ingredient list. An industrial cola or lemon soda lists "natural and artificial flavours", "citric acid", "high-fructose corn syrup" (or European equivalent: glucose-fructose syrup). A Fentimans Botanical Ginger Beer lists: carbonated water, ginger root, brewed ginger, lemon juice, natural flavourings, sugar, glucose syrup, pear juice, herbal botanicals. The difference is not merely marketing — the flavour complexity derived from actual botanical extraction (ginger root brewed at temperature, citrus cold-pressed, herbs macerated) is genuinely different from synthetic approximations.
Carbonation is a less discussed but important differentiator. Industrial soft drinks are carbonated to maximum saturation (typically 3.5-4.5 volumes of CO2) for shelf stability and the characteristic aggressive fizz. Craft sodas often use lower carbonation levels (2.5-3.5 volumes), which allows more of the botanical aromatic to be perceived — high carbonation suppresses some volatile aromatics and overwhelms more delicate flavours. Premium tonic water producers like Fever-Tree specifically calibrate their carbonation level for use with spirits and NA spirits, where the mixer's role is to complement rather than dominate.
Sugar content varies widely and is a useful quality signal — but not in the expected direction. Very low sugar craft sodas (< 5g/100ml) aren't necessarily better than those with 8-10g/100ml if the lower sugar has been achieved with artificial sweeteners rather than natural reduction. The best craft sodas use real sugar at moderate levels (6-12g/100ml), relying on botanical complexity rather than sweetness to deliver flavour. This is significantly lower than industrial soft drinks (10-12g/100ml of sugar without the botanical complexity).
The category boundary between craft soda and premium tonic water is blurry — many premium tonic waters are craft sodas by any meaningful definition. The tonic water category is itself experiencing a premiumisation: from Schweppes' dominance until the mid-2000s to today's fragmented landscape of Fever-Tree (UK), 1724 (Argentina), East Imperial (New Zealand) and Thomas Henry (Germany), each with distinct flavour profiles designed to complement specific spirits categories.
