Starting up a new drinks brand. It's starting off as mixed drinks including alcohol. Few problems which I was hoping to get some help with are: If it's fizzy what's going to be the cheapest way to get it pressurised (believe that's what it's called). Do we need to use preservatives? The plan would be to do it all from home (mix everything at home and bottle it ourselves, and if it takes off then look at alternative methods). Also at the start we'd be using like spirits that are shop bought/wholesale bought, is this okay? Any other tips? Cheers.
