How old do you have to be brew your own beer?

In most jurisdictions, the minimum age to brew your own beer is the same as the legal drinking age. In the United States, this is 21 years old. However, there are some states and localities that have lower age limits for homebrewing. For example, in some states, it is legal to brew beer at home as young as 18 years old. It is important to check the laws in your area to make sure you are old enough to brew beer legally.
