We bought a hard root beer kit--we are new to this--a friend says not to boil, the kit has boiling instructions. Is it necessary to boil to make beer?
Most of the time wort is boiled. It sanitizes the beer, creates reactions that affects the flavour and helps with hop isomerization.
There are exceptions, but there aren't many.
Rather follow the instructions. We can only assume that the company that made the product wishes you to have the best possible product.
