What is the correct temperature to stop the steaming process for milk in a small tin?

The ideal temperature to stop the steaming process for milk in a small tin is 140 degrees. This temperature is optimal for achieving the right texture and consistency without scalding the milk. When milk is heated to this temperature, it reaches a pleasant warmth that enhances its sweetness and allows for the development of microfoam, which is essential for crafting high-quality espresso beverages.

At 140 degrees, the milk maintains a balance between being hot enough for a pleasant drinking experience while avoiding the risk of burning, which can occur at higher temperatures. Milk that is steamed beyond this point, especially towards 150 degrees or above, can lose its creamy texture and may develop an undesirable scorched flavor. Therefore, steaming to 140 degrees ensures the milk remains enjoyable and complements the flavor profile of espresso drinks effectively.
