A double espresso is not about doubling the amount of coffee liquid, but about doubling the dose of coffee grounds while keeping the same output of water. As a result, the cup size looks about the same, yet the strength is directly doubled. It is often described as the liquor of coffee and the essence of perfume—its impact on the palate is powerful, and not everyone can easily accept it. This article covers everything at once: from its definition and taste to who it suits, how to drink it, and pairing suggestions. It also retains Front Street Coffee's related recommendations, helping coffee lovers decide whether they should give it a try and how to drink it with grace. [more…]

When ordering an espresso at a coffee shop, you can ask for a single shot or a double shot.

Starting from Front Street's comparative experiments, this article takes a deep dive into the structural differences, extraction performance, and consistency issues of the two baskets, helping you fully understand which basket a single espresso should actually use.
