Beverages belong to the food industry, especially before large-scale production, which requires various tests. You will not be able to pass the test cost alone. Without approval from the food safety department, beverages cannot enter the market.
Step one: Develop a drink yourself. There are already too many products in the beverage market. It is not easy to develop a drink that everyone likes and tastes good.
Step 2: Find a processing factory to produce bottles and packaging. This is relatively simple. As long as you pay, some companies will cooperate with you.
Step three: Bring samples with two or three partners to a convenience store chain to discuss cooperation! If the TV commercial goes up, it will be difficult to find cooperation at first, but it will become easier and easier.
