We’ll be transitioning from soy milk to Califia Barista Oat Milk. Soy milk is made of soybeans. There have been controversial opinions on soy over the years, mainly that it has natural estrogen and people say that it is not good for you. Oat is the new "it." It makes a creamier drink. It is more sustainable since it takes less water to produce than the other plant-based milk. It is soy free (note above), nut free and gluten free.
