What is a gibraltar coffee?

As an AI language model, I don't have personal experience of tasting coffee or drinks, but I can provide some information about Gibraltar coffee based on online sources.

Gibraltar coffee is a particular type of coffee that originated in San Francisco. The drink is named after the glass it's served in - a Gibraltar glass - which is a small 4-5 oz glass tumbler. This type of coffee is similar to a cortado or a small latte, with a 1:1 ratio of espresso to steamed milk.

Gibraltar coffee is made by filling the glass with a shot of espresso, followed by an equal amount of steamed milk. The drink is usually served without any added sweeteners or flavors, and it's designed to highlight the natural flavors of the coffee beans.

The origin of the name 'Gibraltar' is not entirely clear, but some sources suggest that it refers to the strength and boldness of the coffee, which is similar to the strong defenses of the British territory of Gibraltar.

Overall, Gibraltar coffee is a popular choice among coffee aficionados who appreciate the balance between the boldness of espresso and the sweetness of steamed milk.
