Why is Oat Milk Popular?

Because I’m lactose intolerant, I’ve tried just about every type of non-dairy milk over the years. Let me tell you, they areย not all created alike!

Perhaps the biggest reason that oat milk has become so popular lately is that it has a smooth, mild taste. It doesn’t have an aftertaste like soy milk or coconut milk. This makes it perfect for adding to coffee, cereal, etc. because it won’t change the flavor of your drink or dish.

If you like a foamy cappuccino, then oat milk is one of the best non-dairy options in that beverage because it foams well. While oat milk doesn’t foamย quite as fluffy as dairy milk, it is easier to foam than almond milk or coconut milk.

And if you like to make your own at home, you’ll love oat milk because it is so EASY! Just blend, strain, and it’s ready to drink!

Which Oat is the Best for Oat Milk?

When shopping for oats, you might notice there are a few different kinds available at the grocery store:

  1. Rolled Oats
  2. Instant Oats
  3. Steel-cut Oats

While you could technically use any of the above, the results will vary depending on which type of oat you choose.

For the best texture and creamiest taste, I recommend using rolled oats. Steel cut oats are less processed, which is usually a good thing, but in this case they don’t work as well. Instant oats or quick-cooking oats areย too processed and you may end up with a watery consistency.

How to Make Homemade Oat Milk at Home

Add all ingredients to your food processor or blender.

Blend on high for about 3 minutes until finely processed.

straining homemade oat milk through cheesecloth

Place a cheesecloth over top of a medium mixing bowl. Pour your liquid through the cheesecloth, so that any solids are caught and the oat milk passes through.

Fold the ends of the cheesecloth up and squeeze and remaining liquid out into the bowl.

Transfer to mason jar or other storage container and keep in the fridge. Shake well before enjoying, as your oat milk may separate a bit while in the fridge.

How Long Does Homemade Oat Milk Stay Good?

Your homemade oat milk should last up to a week in the refrigerator.

How to tell if your oat milk has gone bad:

  • It smells “off”
  • It stays separated, even after shaking vigorously
  • The color has changed

When in doubt, toss it! It’s easy to make another batch!
