Many coffee enthusiasts have heard the claim that a long bloom time can lead to under-extraction. This idea seems to contradict our usual understanding of what blooming does. Blooming is meant to release carbon dioxide and improve extraction efficiency, so why would a longer bloom time actually lower the extraction yield? In this article, we compare brewing experiments with two bloom durations—30 seconds and 1 minute 30 seconds—measuring concentration, extraction yield, drawdown speed, and water temperature changes, in an attempt to reveal the true relationship between bloom time and extraction results, and to explore under what extreme conditions an overly long bloom might actually cause under-extraction.

Recently, a friend came across a post online: "If the blooming time is too long, it's easy to brew coffee that is under-extracted." Obviously, this statement goes against our long-standing understanding of blooming. Because as everyone knows, the purpose of blooming is to release the carbon dioxide in the coffee grounds, allowing us to more easily extract the coffee. [more…]

In the genealogy of espresso drinks, Americano, Latte, and Cappuccino have long dominated the mainstream view, while Lungo and Long Black have in recent years gradually entered the discussion among coffee enthusiasts, yet are often mistaken for variations of Americano. In fact, these three differ fundamentally in extraction logic, ingredient ratios, and flavor presentation. Starting from Front Street Coffee's daily extraction practice, this article systematically sorts out the definitions, preparation parameters, and taste characteristics of Americano, Lungo, and Long Black, and uses the same Sunflower Warm Sun blend bean as a sample to compare how the three methods bring out different expressions of coffee flavor, helping readers build a clear cognitive framework for espresso drinks.

In recent years, many specialty coffee shops have started offering a coffee called "Long Extract." For those not very familiar with the espresso system, this term might be quite unfamiliar. But if we use its original Italian name Lungo, I believe many people would not find it surprising. Lungo is actually a member of the espresso family, standing alongside Ristretto and regular Espresso, with the main difference being the amount of extracted liquid. So how did Lungo come about? How is it different from Americano and Long Black? What details should be noted when making a delicious Lungo? This article will start from the evolution history of espresso, answer these questions one by one, and share Front Street Coffee's suggestions on bean selection. [more…]

Lungo is often mentioned alongside Long Black, leading many coffee enthusiasts to confuse the two. In fact, Lungo belongs to the espresso family and, like Ristretto, is a type of coffee made directly with an espresso machine without any additional ingredients. Its characteristic is that it obtains more coffee liquid by extending the extraction time, but the concentration decreases accordingly. This article will sort out the historical origins of Lungo, its differences from Long Black and Americano, and how to make a non-bitter Lungo that suits modern tastes by adjusting parameters. It will also introduce the performance of Front Street Coffee's classic espresso blend when making Lungo. [more…]

Many coffee enthusiasts are still unfamiliar with Lungo, and may even confuse it with Long Black. In fact, Lungo, like Ristretto, belongs to the espresso family—both are made directly with an espresso machine without adding any other ingredients. The difference lies in the amount of extracted liquid: a standard espresso uses 20g of grounds to extract about 40ml, Ristretto reduces the liquid to about 30ml to increase concentration, while Lungo extends the extraction time and increases the liquid to about 100ml, with concentration decreasing accordingly. Lungo was born in an era when early espresso machines had pressure of only 1.5~3 bar, and at that time the only way to compensate for insufficient pressure was to extend the extraction. Today, espresso machines are much more efficient, and traditional Lungo tends to be over-bitter, but by adjusting the parameters, it is still possible to make a version that suits modern tastes. In this article, Front Street Coffee will walk you through the origins of Lungo, its differences from Long Black and Ristretto, and how to extract a modern Lungo that isn't bitter. [more…]

In the big family of espresso drinks, Americano, Latte, and Cappuccino have long been well-known classics. However, in recent years, Lungo and Long Black have gradually entered the spotlight of coffee enthusiasts; they are often mistaken for variations of Americano, but in fact each has its own distinct character. Lungo comes from Italian, meaning "long," and is made by extending the extraction to obtain more coffee liquid; Long Black is a favorite among Australians, preserving the crema by adding water first and espresso afterward, delivering a layered taste experience. This article takes Front Street Coffee's Sunflower Warm Sun blend as an example to break down in detail the flavor differences among these three coffees, and includes the standard extraction parameters for espresso, helping you understand their respective characteristics more clearly.

Cold brew coffee is an ideal choice for making iced coffee at home, with a high extraction fault tolerance, allowing you to achieve decent flavor performance without professional equipment. But how should grind size and steeping time be paired, what range should the coffee-to-water ratio be controlled within, and how will the flavor differ at different time points? Based on Front Street's practical experience, this article sorts out the complete logic for making cold brew coffee: the recommended coffee-to-water ratio is 1:12 to 1:13, the grind size references pour-over coarseness (70-85% passing rate through a No. 20 sieve), and the steeping time should be controlled between 8 and 24 hours. At the same time, it provides two practical approaches—coarse grind with a long time, and medium-fine grind with a medium-long time—along with the complete cold brew making steps and Front Street bean recommendations.

Recently, many specialty coffee shops have started selling a "niche" coffee—the "Long Extraction." For friends who are not deeply into coffee, Long Extraction can be quite unfamiliar, so recently many friends have often asked Front Street what Long Extraction is. To be honest, Front Street believes that the main reason everyone finds it unfamiliar [more…]

Facing Long Black, Lungo, and Americano on the menu, many coffee lovers often can't tell them apart. Although they are all black coffee, their preparation methods and flavor profiles each have their own merits. Long Black is the Australian's unique interpretation of espresso diluted with water, with a smaller cup size and a richer taste; Lungo is an extended espresso obtained by lengthening the extraction time, with a more pronounced bitterness; and Americano is the product of American soldiers diluting espresso to suit their taste during World War II. This article will break down in detail the differences between these three black coffees from the aspects of historical origins, brewing parameters, crema performance, and drinking experience, and cite extraction examples from Front Street Coffee to help you make a clearer choice the next time you order.
