Is it better to drink coffee with oat milk?

4 min read

According to data from Kantar, oat milk has become Britain's most preferred plant-based drink, with sales rising over 7% in a single year. This surge in popularity raises a key question for coffee lovers: is it better to drink coffee with oat milk? The answer hinges on individual preference, dietary needs, and environmental values.

Quick Summary

This article analyzes the factors that determine if oat milk is the ideal coffee companion for you, examining its texture, flavor profile, nutritional content, and environmental impact compared to regular dairy milk. It also provides tips for preventing curdling and highlights the benefits of barista-style varieties.

Key Points

  • Taste and Texture: Oat milk offers a naturally creamy texture and a mild, slightly sweet flavor that complements coffee without overpowering its taste, making it a popular choice for many.

  • Superior Frothing: Barista-style oat milks are specially formulated to create a rich, silky microfoam perfect for lattes and latte art, a significant advantage over many other non-dairy milks.

  • Sustainability: Oat milk production has a significantly lower environmental impact, requiring less water and land compared to dairy milk, making it a greener choice for eco-conscious consumers.

  • Nutritional Considerations: Oat milk is naturally lactose-free and often lower in saturated fat than cow's milk, but it can be higher in carbohydrates and lower in protein, and some commercial versions contain added sugars and oils.

  • Prevents Curdling: To avoid separation in hot coffee, it is best to use a barista-grade oat milk and warm it gently before adding it to your brew.

  • Personal Preference Matters: The best milk is subjective and depends on your dietary needs, taste preferences, and environmental values, as there are trade-offs between oat and dairy milk.

The Oat Milk Appeal: Flavor, Texture, and Frothing

Oat milk has secured its place as the top dairy-free option in coffee shops for a reason. Its success largely comes from its unique ability to replicate many of the desirable qualities of cow's milk when mixed with coffee. Unlike some other plant-based milks that can taste watery or overpower the coffee's flavor, oat milk offers a naturally creamy texture and a mild, slightly sweet flavor. This neutral profile complements the coffee's inherent bitterness without altering its flavor significantly, appealing to a broad range of tastes.

For those who love lattes and cappuccinos, oat milk's superior frothing ability is a major draw. Specially formulated 'barista' varieties are designed to create a rich, stable, and silky microfoam, perfect for latte art. This contrasts with some other plant-based milks that produce less stable, larger bubbles when frothed. This foam stability is achieved through added oils and stabilizers, which are more prevalent in commercial barista versions.

Potential Downsides: Processing and Nutrition

While oat milk offers many benefits, it's not without its potential drawbacks. The processing required to turn dry oats into a creamy, shelf-stable liquid often involves more steps and ingredients than simply milking a cow. Many commercial oat milks, particularly the barista editions, contain added oils (like rapeseed or sunflower) and stabilizers to improve texture and prevent separation.

Some nutritionists have raised concerns about the sugar content and glycemic impact of oat milk. The enzymatic process used to break down the oats' starches releases natural sugars, and some brands also add sweeteners. A high intake of oat milk could potentially cause a blood sugar spike, though this is less of a concern when consumed in smaller quantities in coffee. Additionally, oat milk is typically lower in protein than dairy milk or soy milk, which can be a consideration for those monitoring their protein intake.

Avoiding the Curdle: How to Ensure a Smooth Cup

One common frustration with plant-based milks is curdling, a chemical reaction that occurs when milk proteins separate from the liquid. This happens when acidic coffee is combined with cold oat milk, especially if the milk isn't designed for coffee. Fortunately, several steps can prevent this issue:

  • Use Barista Edition Oat Milk: These versions contain stabilizers and are formulated to resist curdling.
  • Warm Your Milk: Gently warming the oat milk before adding it to hot coffee minimizes the temperature shock that can cause separation.
  • Pour Slowly: Adding the coffee slowly to the warmed milk, or vice versa, allows for a more gradual mixing and reduces the risk of curdling.

Oat Milk vs. Dairy Milk: A Comparative Look

Choosing between oat milk and regular dairy milk often comes down to weighing personal taste and health goals against other factors like sustainability. Below is a comparison to help inform your decision.

Feature Oat Milk Dairy Milk (Cow's Milk)
Flavor Profile Mild, slightly sweet, subtle oaty taste. Neutral and creamy, can vary based on fat content.
Texture Naturally creamy, can be enhanced with stabilizers in barista versions. Rich, full-bodied, with varying creaminess based on fat content.
Frothing Excellent frothing ability, especially barista varieties, for silky microfoam. Traditional favorite for frothing, producing a rich, velvety foam.
Sustainability Significantly smaller environmental footprint, requiring less water and land. Higher environmental impact due to larger water and land use.
Protein Content Generally lower in protein, though some brands may add it. Complete protein source, naturally high in protein.
Saturated Fat Minimal saturated fat. Higher in saturated fat, especially in whole milk.
Lactose Lactose-free, ideal for individuals with lactose intolerance. Contains lactose, which can cause digestive issues for intolerant individuals.
Key Nutrients Often fortified with vitamins like D and B12. Naturally rich in calcium, phosphorus, and B vitamins.

Making the Decision

Ultimately, whether it is 'better' to drink coffee with oat milk is a personal decision, as there is no single right answer. For those with a dairy intolerance or a vegan lifestyle, oat milk is an excellent, creamy substitute that performs exceptionally well in coffee drinks. It also presents a more sustainable option for the environmentally conscious. However, those focused on higher protein intake might still prefer dairy, while others concerned with added ingredients or sugar spikes may opt for a different alternative or plain black coffee.

For a smooth experience, selecting a high-quality barista-style oat milk is key. Brands like Oatly and Minor Figures are known for their stable performance and neutral taste that beautifully complements your coffee. By considering your personal priorities—whether it's taste, nutrition, or environmental impact—you can determine the best option for your daily cup.

Conclusion: The Best Choice for You

The ideal milk for your coffee comes down to a balance of personal needs and preferences. If you seek a creamy, great-tasting, and environmentally friendly dairy-free option that excels in lattes, oat milk is a fantastic choice. Its ability to froth and its neutral flavor profile are widely praised by baristas and consumers alike. However, if your primary concerns are high protein content or minimizing processed ingredients, you might find dairy milk or a different plant-based alternative more suitable. The rise of oat milk has created more choices than ever, allowing everyone to find their perfect cup.
