Being on a low-carb diet shouldn't mean that you have to give up your daily caffeine intake

Oat milk is one of the best plant-based choices to replace cow’s milk without losing any sweetness. But drinking oat milk by itself time and again is not the best resort. So why not prepare some stellar recipes by adding coffee into your oat milk? 

The creamy texture and mild sweetness in oat milk will lower the bitterness in your coffee fix. Today, there are many insanely cool coffee oat milk drinks to inspire your taste buds, such as chai lattes, iced lattes, or iced mochas. So the real question here is, what type of coffee is the best choice for oat milk?

Fresh, organic coffee always performs better than a ton of additives. Go for plain, bean-to-ground coffee to pair with oat milk instead of low-quality instant coffee with sugar and other harmful substances.


Some people prefer outstandingly strong coffee like Robusta, while others prefer less intense flavor in a perfect Arabica batch. 

Coffee Quality

Understand what makes a quality coffee. The best coffee will have a strong, pleasant aroma that smells fresh.


Buy a small batch instead of a large one. Coffee will lose its freshness after it is roasted, especially if you don't know how to store it right.

The Best Arabica Coffee For Oat Milk 

I recommend Arabica beans because of the flavor; Gevalia Traditional Roast Mild is a great choice. Since Arabica coffee beans are grown and harvested at a higher elevation, their tasting profile is more diverse than Robusta coffee.

Arabica beans have a low acidity level, and that's why this type of coffee introduces a smoother texture to your throat. When the coffee escapes from your throat, it will leave flavor notes of chocolate and sugar in the aftertaste. Plus, Arabica beans are grown without the use of animal fertilizer. 


  • Low acidity for a smoother texture
  • Easy to store
  • Slow roasted, snap cooled beans to lock in flavor and aroma
  • Compatible with all coffee makers


  • More expensive
  • Difficult to farm, and that’s way harder to find
  • Less caffeine

The Best Coffee For Oat Milk For Those Who Need A Boost

Robusta follows Arabica to be one of the most popular types of coffee consumed in the world. Robusta coffee is a reasonable option to pair with oat milk if you don't want to overspend on a simple drink. 

The nature of Robusta leans towards bitterness and harshness due to the higher concentration of caffeine compared to Arabica. 

As a Vietnamese coffee lover, Robusta is second to none and I love its earthy flavor and a peanut-ty aftertaste. The Trung Nguyen Vietnamese Coffee is a perfect blend of Arabica and Robusta that will ensure your drink will have a deep note of chocolate to pair with that extra sweetness and a thick crema. However, make sure to use just the right amount of Robusta black coffee; otherwise, it will out-mask the delicate taste of oat milk.


  • Low in fat
  • Cheap
  • Deep, intense flavor and high in caffeine
  • Fruity fragrance and chocolate hints


  • Less diverse flavor
  • Bitter
  • Some coffee filters don’t agree with the size of the ground

The Best Light Roast Coffee For Oat Milk

  • Rainforest Alliance certified
  • Flavors hold up over time

The Best Honey-Process Coffee For Oat Milk

Honey-process coffee is gradually taking the world by storm thanks to its mellow flavor from the sticky-sweet beans. The reason why honey-processed coffee makes a perfect pairing with oat milk is the “just right” processing method which allows the beans to preserve their clarity and sharpness. 

After being ground, the Jaya Family's Plantation honey-process coffee will lend its depth of flavor to serve as the backbone of the oat milk. The mild sweetness of oat milk, when blended with notes of chocolate, brown sugar, spice, and cedarwood in The Jaya Family's Plantation honey-processed coffee, will create a great drink. When the mixture escapes from your throat, what’s left behind is a natural sweetness and floral qualities that make you crave more.


  • Complex flavors
  • Uniform and round taste with a balance of sourness
  • Strong sweetness
  • 100% processed organic Ecuadorian coffee


  • Not widely available
  • More acidic
  • Lack of the initial brightness of a wet coffee

Testing Criteria

The final flavor is my main concentration when testing out how oat milk reacts to different types of coffee. However, that is not the only thing that went into my consideration. I played around with different recipes for each combination, less of this and more of that, before deciding which coffee is the best pairing for oat milk.

The recipe plays a crucial role in my testing. It can define whether or not the blend turns out fine. Even if I pick the proper coffee, but the ratio is incorrect, the drink will eventually go wrong.

Date of use is another factor that came to play. Open oat milk can stay up to 10 days in the fridge, but the flavor gradually fades towards the end of its lifespan. I made sure the recipe used freshly opened oat milk so that I wouldn’t miss out on its freshness, creaminess, and aroma.

Why You Can Trust Me

Ever since I went on a diet a year ago, I have paid more attention to everything I eat. And that goes the same way for a drink. Coffee with condensed milk had always been my go-to drink, but I finally changed it to plant-based milk to cut on calories without sacrificing the flavor I love. 

The Caribou light-roast coffee is my top pick if I have a chance to find a decent specialty coffee shop. For those who aren’t big fans of mild coffee, go for the Robusta blend and enjoy its strong bitterness but make sure to add just the right amount of coffee so it won’t bother the natural sweetness of oat milk. Look at the product links I provided or visit a trusted coffee store and talk to the sellers before buying the proper coffee for oat milk.
