On the menu at Blue Bottle Coffee shops, there is a drink with a tongue-twisting name that is particularly intriguing—the Gibraltar. It is at once the name of a port city, the designation of Libbey's classic glassware series, and a rich little milk coffee that sits somewhere between a latte and a macchiato. This drink was not deliberately developed, but arose from an accidental purchase of the wrong glass: a 4.5-ounce small glass could not hold a regular milk coffee, yet it was just right for observing espresso crema, so a barista blended a small amount of thin-microfoam milk into a double espresso, accidentally creating an off-menu hit. Today, Front Street takes everyone through the origins of the Gibraltar, compares its similarities and differences with the cortado, and finally provides a home recipe with parameter references.

Cortado is a mini espresso milk coffee originating from the Basque region of Spain, with a name derived from the Spanish word "cortar," meaning "to cut." It uses a small amount of steamed milk to "cut into" espresso, forming a classic ratio of 1:1 or 1:0.5, with a very small cup size, and typically without frothing the milk or retaining only an ultra-thin milk foam. As Cortado spread to Saudi Arabia, Costa Rica, Italy, Malaysia, and other places, local baristas continuously adjusted the recipe according to local tastes, giving rise to modified versions like Blue Bottle's Gibraltar and Cuba's Cortadito. In this article, Front Street Coffee breaks down the traditional characteristics of Cortado, its global variations, and compares its recipe and flavor with Piccolo coffee, helping coffee enthusiasts clarify the unique features of this lesser-known espresso coffee.

Among the wide variety of espresso-based milk coffees, the Cortado is a rather obscure presence—it is made simply by mixing espresso with hot milk in proportion, simple to prepare yet outstanding in flavor. Originating from the Basque region of Spain, this drink, with its 1:1 ratio of coffee to milk, reduces the heaviness of the espresso while preserving its rich coffee aroma, and is popular in Spain, Portugal, Cuba, and elsewhere. As it spread, it was continually adapted in different countries, also giving rise to classic variations such as the Gibraltar. This article walks you through the origins of the Cortado, its traditional preparation, its evolution across regions, and how it differs from the similar-looking, equally small-cup Piccolo coffee.

Dirty has always been a popular product in coffee shops thanks to its high aesthetic appeal and the unique experience of hot and cold colliding. When making a Dirty, using a chilled glass can extend the layering effect between the espresso and the milk, but should you use a refrigerated glass or a frozen glass?

When buy-one-get-one promotions can no longer easily spark the urge to purchase, the promotional logic of coffee brands may be facing a turning point. [more…]
