Milk Frothing

Why Milk Texture Matters

The difference between a mediocre and an extraordinary cappuccino often comes down to milk texture. Perfectly frothed milk, known as microfoam, is glossy, velvety, and sweet. It integrates seamlessly with espresso rather than sitting on top like stiff peaks of foam.

Steam Wand Technique

Phase 1: Stretching (Aerating)

1. Start with cold, fresh milk filled to just below the spout
2. Position steam tip just below the milk surface
3. Open steam, you should hear a gentle "tss-tss" sound
4. Stretch for 2-5 seconds (cappuccino needs more; flat white less)

Phase 2: Spinning (Texturing)

1. Lower the pitcher so the tip is deeper in the milk
2. Create a whirlpool vortex, milk spinning in a circular motion
3. Continue until the pitcher is too hot to hold comfortably (60-65°C)
4. Turn off steam

Signs of Good Microfoam

• Glossy surface, like wet paint
• No visible bubbles, uniform, micro-fine texture
• Pours like thick cream, flows smoothly, not in clumps
• Sweet taste, milk sugars are activated at 60-65°C

Common Mistakes

• Starting with warm milk, less time to texture properly
• Over-aerating, produces stiff, dry foam
• Heating past 70°C, milk proteins break down, becoming bitter
• Not creating a vortex, results in uneven texture with large bubbles

Milk Choice

Whole milk is easiest to work with, its fat content creates the richest, most stable microfoam. Lower-fat milks can work but require more skill. For plant-based options, see our guide on plant milks in coffee.

At Röstschmiede, we believe great milk frothing is a learnable skill. With practice and attention, anyone can produce cafe-quality microfoam at home.
