This device, a small metal pipe attached to an espresso machine, uses pressurized steam to froth and heat milk for various coffee beverages. The pressurized steam is injected into milk, creating microfoam a velvety texture essential for latte art and enhancing the flavor and texture of the drink. This component is typically made of stainless steel due to its durability, heat resistance, and ease of cleaning.
The introduction of this tool revolutionized espresso-based drinks. Before its widespread adoption, creating textured milk was a more challenging and less consistent process. The ability to easily produce microfoam elevated the quality and aesthetic appeal of coffee beverages, contributing significantly to the popularity of specialty coffee culture. Its availability in both commercial and home espresso machines allows baristas and coffee enthusiasts alike to craft a wide range of drinks from lattes and cappuccinos to macchiatos and flat whites. Proper technique is crucial for optimal results, influencing the texture, temperature, and overall quality of the steamed milk.
