There's no one way to make a michelada, but in addition to beer, this cocktail often contains lime juice, salt, tomato juice, hot sauce, and spices. You could make a non-alcoholic version with near beer. However, Whole Living has what we think might be a tastier idea: kombucha. Their recipe substitutes kombucha tea for the cerveza and includes tomato paste for richness.

You could also experiment with using kombucha in your own favorite michelada recipe. Do be aware that some kombuchas contain a trace amount of alcohol (or even more, if homemade), so if you or your guests are completely abstaining, this might not work for you.
