In front of a café bar, you can often hear the "hissing" sound a barista makes while steaming milk, and you'll also notice that they always purge the steam wand for a few seconds before and after use, sometimes even keeping it wrapped in a cloth the whole time. These seemingly superfluous little habits actually reflect careful consideration for coffee quality and operational safety. Purging the steam not only expels condensation from inside the wand and prevents the milk from being diluted, but also cleans the steam holes to keep them from clogging. As for whether the steam wand should be wrapped in a milk cloth, baristas each have their own reasoning: some insist that wrapping it is safer and more efficient, while others believe it is completely unnecessary. This article will examine both sides of the argument and analyze in detail this dispute over a fine point of espresso preparation, helping coffee enthusiasts gain a deeper understanding of the correct way to steam milk.
