Milk being poured into an iced coffee
Why You Shouldn’t Pour Freshly Brewed Espresso Over Ice
A common pitfall when making espresso is pulling an espresso shot over ice. While it seems convenient, doing it this way will actually diminish the flavor.
The impact of the ice on the espresso affects the flavor, leading to an over-extracted taste. The coffee will become bitter and one-dimensional, with limited acidity and sweetness.
To avoid these problems, pour the espresso over cold water or milk first, and then add the ice and stir. This will gradually cool the coffee rather than shock it.
