What is Agua de Avena?
Also known as horchata de avena, or oat horchata, this traditional drink is prepared using soaked oats, cinnamon, and brown sugar to deliver a refreshing and nutritious agua fresca that is perfect to serve for lunch, dinners, or just to enjoy as a refreshing snack in the afternoon.
Agua de avena has a hearty and slightly sweet taste, you can also control how much sugar you add or what type of sweetener, making it also a healthier option for bottled beverages.
Oat (avena) benefits
Oats are a superfood packed with fiber, vitamins, and minerals besides being naturally gluten-free, so perfect for people with specific dietary needs.
Fiber has been proved to be good against type 2 diabetes, cardiovascular disease, and some types of cancer; besides being very important for a well-functioning digestive system.
But something important to note is that you should always choose the type of oats to consume. For the most health benefits, you can opt for old-fashioned, rolled, or steel-cut oats instead of quick oats because the last is lower in fiber than the others.

How To Make It
Place old-fashioned oats in a bowl and pour 2 cups of water. Add the cinnamon stick and mix well. Leave it to soak for 30 minutes or even better, overnight.
Transfer oats, soaking water, and cinnamon stick to a blender and blend until smooth.
Using a fine sieve, strain the oats mixture into a large pitcher. Add vanilla extract and brown sugar, then mix well to dissolve the sugar.
Add the remaining 8 cups of water to the pitcher and mix. Taste, and if you want, add more sugar until is sweet to your liking.
Serve in glasses with crushed ice and sprinkle a bit of cinnamon powder on top. Enjoy!
- Use room temperature water so the sugar would be easier to dissolve.
- Adjust sweet to your taste by adding more or even less that the recipe suggest.
- Do not add ice to the pitcher unless you intend to serve all the drink at once, otherwise it will dilute and become flavorless.
- Use other types of sweeteners if you want to. Such as monk fruit, stevia, regular white sugar, or even honey.
- Replace 2 cups of water with 2 cups of your favorite plant-based milk to make a creamy version. I recommend almond or coconut milk.
This oat horchata keeps nicely in the fridge for up to 3 days, just make sure to store it in a large container with a tight lid to prevent it from absorbing other smells.
You can also store the oat’s concentrate first. Blend soaked oats with cinnamon and a bit of water as indicated in the recipe. Place the mixture in a container and freeze for up to 3 months. When needed, thaw it and use it to make your agua de avena.
