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.
