Kombucha and fermented sodas: small-batch brewing where alcohol content decides the business
You brew it, bottle it and deliver to cafés. Brewing is the easy part. Keeping the drink below the line where a soft drink legally becomes alcohol is not.

You brew kombucha or other fermented sodas in a small production space and sell to cafés, bistros, farm shops and markets. The kit is cheap and the recipe can be learned at home. What separates a hobby from a business is not flavour — it is keeping a living drink stable from the moment you cap the bottle to the moment it reaches the customer's shelf. Fermentation does not stop when you close the lid.
Grown-up soft drinks are still thin on the ground. Venues know it, and they are looking for something they can pour into a glass and charge for properly, rather than a fizzy drink meant for children.
💡 Why it works
🥂A grown-up alcohol-free option is still missing
The share of people skipping alcohol keeps growing, but venue menus lag behind. Cafés do not want to serve a sugary fizzy drink to a guest who would otherwise order a cocktail — and they want something whose price they can defend.
