Out of nowhere, you might have to swap out your morning espresso for an oat milk latte. Oat milk is my favorite non-dairy option, but not all oat milks are built the same, especially when it comes to frothing like dairy milk. A latte requires fluffy steamed milk, and a good oat milk latte can be difficult to make. So, I decided to use those two tools to decide which oat milk would be the best replacement for milk. I’ve used the Califia Farms oat and almond milks before, but I never tried their Barista oat milk.
