How do I start a beer/soda business?
Go to the fiverr site and get a business plan for a craft brew pub or restaurant. You will need less permits for a soda business.
Learn to brew beer or make soda or hire someone who can.... and then open up a soda fountain or a beer bar. Start with paying your accountant to make you a business plan so you will know how much money you need.
i assume that you will need to apply for a few licenses, especially for the beer
