Hard kombucha has quickly evolved from a niche wellness-adjacent product into a full-fledged drinks category, earning shelf space in everything from independent bottle shops to major retailers. What started as a small movement in California has grown into an international trend, driven by changing attitudes toward alcohol, health, and flavour. As more people look for alternatives to traditional beer, wine, and spirits, hard kombucha is emerging as a natural answer.
It’s lighter than many alcoholic options, often sitting between 4% and 6% ABV, and it offers something more layered than your average canned cocktail or seltzer. Naturally gluten-free and brewed with natural ingredients, it brings a different kind of energy to the table. One that’s rooted in fermentation, function, and flavour.
Across the US, Europe, and now the UK, a new generation of brands is redefining what it means to drink better. Some are all about bold flavours, others lean into wellness, and a few are pushing boundaries with packaging and attitude. We've pulled together ten of the most interesting hard kombucha brands to know right now — each bringing something unique to the category. And yes, we’ve included BUCI too.
1. BUCI
BUCI is leading the new wave of hard kombucha in available the UK, offering a more elevated and modern take on the category.

It’s made for drinkers who care about what’s in their glass. Flavour-forward, refreshingly dry, and brewed without compromise.
