Why you should never resteam milk (and what to do instead)
The morning rush is intense. Orders are flying, and you’ve got a pitcher of steamed milk that’s been sitting too long. The foam has separated, and it’s no longer silky smooth. The temptation to give it a quick blast from the steam wand is strong, but resist.
Resteaming milk is a common shortcut that harms your coffee quality and your customers’ experience. Here’s why you should avoid it.
What happens when you steam milk correctly
Proper steaming has two goals:
- Heating: Steam heats the milk while creating a vortex that unfolds proteins
- Texturing: These proteins trap air, creating stable, dense microfoam
The result? Silky, glossy, sweet milk with integrated foam, perfect for latte art and delicious coffee.
Why resteaming ruins everything
It burns sugars and denatures proteins
Fresh milk steamed to 140-150°F (60-65°C) breaks down lactose, enhancing natural sweetness. Resteaming pushes milk far beyond this temperature, burning the sugars and creating a sulfuric, eggy taste. The proteins denature, losing their ability to hold air—you get bubbly, stiff, separated foam instead of silky microfoam.
The texture falls apart
Resteaming doesn’t reintegrate foam—it destroys it. Instead of smooth, velvety texture, you get large, airy bubbles on top of thin, watery milk. This dry, clumpy foam separates instantly and makes latte art impossible.
You lose the creamy mouthfeel
Overheating breaks down fats, leaving beverages thin and lifeless. That luxurious texture customers expect from specialty coffee? Completely gone.
The industry standard
The Specialty Coffee Association (SCA) emphasizes precision, consistency, and quality. Their barista training focuses on steaming the correct amount of fresh, cold milk for each drink. Resteaming contradicts everything the SCA stands for because it sacrifices:
- Taste
- Texture
- Temperature
A modern solution
Traditional steam wands create challenges during busy service. The Latte Art Factory offers an innovative alternative with steam-free foaming technology:
