Plant-Based Milk in Coffee

The Rise of Plant Milk

Plant-based milks have gone from niche alternative to mainstream cafe staple. Whether for dietary, ethical, or taste reasons, more coffee drinkers than ever are choosing non-dairy options. The good news: quality has improved dramatically, with several plant milks now performing beautifully with espresso.

Oat Milk — The Barista Favorite

Oat milk has become the default plant milk in specialty coffee for good reason:

• Naturally sweet and creamy with a neutral flavor
• Froths well — barista-grade versions produce excellent microfoam
• Does not curdle in hot coffee
• Complements coffee flavor without overpowering it
• Brands like Oatly Barista and Minor Figures lead the market

Soy Milk — The Original

• High protein content creates stable, creamy foam
• Neutral flavor when fresh and high quality
• Can curdle with very hot or very acidic coffee — pour milk first, then add espresso
• Best with medium to dark roasts

Almond Milk

• Light, nutty flavor that can complement or compete with coffee
• Thin texture — harder to froth without barista-grade versions
• Can separate in very hot beverages
• Best for iced drinks and lighter coffee preparations

Coconut Milk

• Rich, creamy body with distinct tropical flavor
• Froths reasonably well
• Flavor-forward — not suitable if you want the coffee to shine
• Works well in cold brew and tropical-inspired drinks

Tips for Plant Milk in Espresso

• Always choose barista-grade versions — they contain added oils or stabilizers for better performance
• Temperature matters — plant milks scorch faster than dairy; steam to 55-60°C max
• Acidity and curdling — lighter roasts with higher acidity can cause separation

At Röstschmiede, we always offer oat milk as our standard plant-based option because it consistently delivers the best results in terms of flavor, texture, and compatibility with our coffees.
