Introduction:As a member of the espresso family, Lungo is often mistaken for Americano or long black coffee. In fact, Lungo is an espresso extracted over a longer period of time, with more water and moderate strength, offering a unique taste and suitable scenarios. This article delves into the definition of Lungo, its differences from espresso, Americano, and long black coffee, and explains its extraction time, volume, flavor characteristics, and practical tips to help you master the brewing techniques of this "stretched-out espresso."
Among the many types of espresso-based drinks, Lungo (pronounced: long-goo) is a often overlooked but distinctive beverage. Although it also uses espresso as its base, Lungo differs significantly from the familiar espresso and Americano in terms of preparation method, taste, and concentration. Understanding Lungo can help you choose the most suitable type of coffee based on your flavor preferences.
In Italian, Lungo means "long" or "extended."This aptly highlights its most prominent feature: compared to a standard espresso, Lungo is made by extending the extraction time, allowing more water to pass through the coffee grounds, resulting in a larger volume of coffee with relatively milder flavor.A standard espresso typically uses about 7 to 9 grams of coffee grounds, with an extraction time of around 25 to 30 seconds, and a yield of about 25 to 30 milliliters; whereas Lungo extends the extraction time to about 1 minute, increasing the yield to50 to 60 milliliters, and can even go up to 85 milliliters (single shot), while a double shot yields about 120 to 170 milliliters.
This extended extraction process makes Lungo smoother and less intense than espresso, but at the same time, due to the longer contact time,its caffeine content is slightly higher than that of traditional espresso, making Lungo a potentially more effective choice for those seeking a caffeine boost. However, because of the longer extraction time, some acidity and delicate flavors may be masked by over-extracted bitterness, so the flavor of Lungo is usually richer and more bitter, though overall still smoother and fuller than Americano, which is simply espresso diluted with water.
Also easily confused with Lungo are Americano and Long Black.Americano is made by diluting espresso with hot water, usually by extracting the espresso first and then pouring hot water into it, with a common volume of 240 to 300 milliliters or more. WhileLong Black is made by pouring hot water first, then extracting the espresso onto the hot water, preserving more crema (coffee foam) on the surface. Lungo, on the other hand, does not add any extra hot water at all; it relies solely on extending the extraction time to allow more water to pass through the coffee grounds, creating a naturally diluted effect, thus it is considered an "extended version of espresso."
These three types of coffee (Lungo, Americano, and Long Black) all belong to the Italian-style black coffee category, but they differ greatly in preparation order, flavor layers, and texture structure. For example, Americano, because it includes additional water, has an overall flavor that is lighter than Lungo, making it suitable for consumers who prefer a refreshing taste; whereas Lungo, since it doesn’t add extra water, retains the coffee oils and the original flavors of the espresso better. Though stronger, it is not as intensely stimulating as pure espresso.
After understanding the uniqueness of Lungo, let’s now look at its actual extraction parameters. Lungo generally uses the same amount of coffee grounds as espresso (about 7 to 9 grams), butthe grind size needs to be adjusted slightly coarser than espresso to speed up the water flow and extend the extraction time. If the same fine grind as espresso is used, it may lead to excessive clogging and over-extraction, resulting in noticeable burnt and bitter flavors. Therefore,appropriately adjusting the grind to be coarser, controlling the extraction time to around 30 to 45 seconds, with a yield of about 50 to 60 milliliters, is the common ideal range for Lungo.
As for blend selection, since Lungo is an espresso-based drink, it is also generally recommended to use stable blends with balanced flavor profiles. Common espresso blends mix beans from different regions, such as a combination of Brazilian and Colombian beans — the former brings body and balance, while the latter provides moderate fruitiness and acidity. Such blends help maintain a certain flavor structure and textural fullness even during extended extraction.
Additionally, the freshness of the coffee beans is crucial for the performance of Lungo.It is recommended to choose coffee beans roasted within 5 days, and let them rest for 4 to 7 days upon receipt for degassing, allowing carbon dioxide to escape and flavors to stabilize, which ensures optimal taste when brewed. If purchasing pre-ground coffee, note that ground coffee cannot degas and loses flavor more quickly, so it’s best to use it promptly and store it properly to minimize oxidation effects.
In summary, Lungo is a coffee option that combines the flavor of espresso with a larger volume, suitable for coffee lovers who enjoy the intensity of espresso but prefer something slightly lighter. From extraction principles and taste differences to practical advice, mastering the characteristics of Lungo allows you to flexibly choose the most suitable Italian-style black coffee according to different situations and personal taste preferences.
