The world is obsessed with kombucha, and now its stronger cousin, hard kombucha, is taking over drinks menus and fridge shelves. If you’ve seen it around and wondered what it actually is, how it’s made, or how it stacks up against beer, cider, and seltzers, you’re in the right place. In this article we break down everything you need to know about hard kombucha: what goes into it, how much alcohol it contains, how it tastes, and why it’s quickly becoming a go-to alternative in the UK.
What is Hard Kombucha?
Hard kombucha is also referred to as alcoholic kombucha is the alcoholic version of kombucha. It’s a fermented tea drink made from tea, sugar, and live cultures. By infusing a spirit or extending fermentation, more sugar is converted into alcohol, giving hard kombucha an ABV of around 4–6%, similar to beer or hard seltzer. Unlike beer, it’s brewed without barley or wheat, making it naturally gluten-free and lighter in calories
How is Hard Kombucha Made?
It starts with the same base as regular kombucha: brewed tea, cane sugar, and a SCOBY (symbiotic culture of bacteria and yeast). During the first fermentation, the cultures consume the sugar, creating natural fizz and acids. To turn kombucha into hard kombucha it is either infused with a spirit or uses a second, longer fermentation, which produces a higher level of alcohol. The result is a crisp, slightly tart drink that can be flavoured with fruit or botanicals.
Every brand of hard kombucha has its own process. Some go for a dry, wine-like finish; others lean into fruity notes. Most hard kombuchas range between 4% and 6% ABV. Some brands push higher, up to 8–10%, but that’s less common. At BUCI, we focus on balance: drinks that are refreshing, flavourful, and endlessly drinkable at 5% ABV, however, as it is alcohol we encourage consumption in moderation.
Is Hard Kombucha Healthy?
Hard kombucha isn’t a health drink — it’s still alcohol. But compared to other options, it can be a better choice. Here’s why:
- Lower sugar than many mixed drinks and cocktails
- Gluten-free, since it’s brewed from tea
- Often fewer calories per can than beer or cider
- Contains live cultures and organic acids from the tea
Think of it as a cleaner alternative to beer or cider, not as a probiotic supplement. If you’re looking for a drink that’s refreshing without being loaded with sugar, hard kombucha definitely delivers. BUCI contains no added sugar, each can has less than 3g.
What Does Hard Kombucha Taste Like?
Hard kombucha generally sits somewhere between sparkling wine, dry cider, and craft soda. The fermentation brings a natural fizz and slight acidity, while fruit and botanical flavours add character.
Depending on the brand, you might find it fruity, floral, tangy, or even spicy. BUCÏ’s flavours are designed to be balanced and easy to drink. We can't speak for every brand, but BUCÏ is delicious:
