Plant-based protein powders can have a variety of flavors, including chocolate, vanilla, strawberry, and even unflavored. Some plant proteins like pea protein powder tend to have a slightly earthy or "beany" flavor, which may not be appealing to everyone. Other plant proteins like soy and hemp have a milder flavor that is often masked well in flavored varieties. Ultimately, the taste of plant protein powder varies widely depending on the type of protein and the manufacturer, so it's best to try a few to find one that you like.
