Why Milk Frothing Pitchers Are Made of Stainless Steel: Heat Control, Durability & Latte Art Explained
If you pay attention to coffee gear, you’ll notice that many tools come in a wide range of materials. Take drippers, for example—you can find them made from resin, ceramic, glass, or stainless steel. But when it comes to milk frothing pitchers, the choice seems almost unanimous: stainless steel. This raises a natural question—are other materials really unsuitable? And if so, why has stainless steel become the near-universal standard? Today, let’s take a closer look at the physical properties and practical considerations that have led to this seemingly one-sided outcome. A truly good milk pitcher needs to meet several strict requirements: excellent heat transfer, controllable temperature rise, durability and strength, and proper hygiene. These demands alone narrow the list of viable materials considerably. Once you understand the core purpose of a milk pitcher and what it must do well, the answer becomes fairly obvious. Heat Conductivity Comes First The most critical factor is he...
