Many coffee enthusiasts, while enjoying an espresso, notice black particles settling at the bottom of the cup and worry whether this means something went wrong with the extraction. In fact, in most cases this phenomenon is perfectly normal. These sediments are extremely fine coffee grounds that have passed through the holes of the portafilter basket, and they usually sink to the bottom gradually after the coffee has rested for a few minutes. This article will explain in detail the principle behind how these fines appear, their relationship with tiger-striped crema, and several factors that may cause a sudden increase in sediment, including grinding too fine and deformation of the basket's mesh. At the same time, Front Street Coffee will also use examples to help you determine when you need to adjust your grinding parameters, so you can face that layer of fine grounds at the bottom of your cup with greater ease.

This article takes three representative drippers—V60, Kalita, and Wave—as examples, starting from the coffee bed structure, explaining one by one the specific routes for circular pouring, and includes solutions for when the water flow is unstable. Whether you are just getting into pour-over or want to advance your understanding of how drippers and pouring techniques pair together, you will find practical reference here. [more…]

What kind of brewing experience does a flat-bottom dripper with manually switchable extraction modes actually deliver? Front Street recently got its hands on Hero's variable-speed cake dripper, which uses a knob mechanism to offer three flow-rate settings—immersion, slow, and uniform—while its flat-bottom design makes it quite beginner-friendly. Front Street has brewed beans such as washed Butterfly Flower, Mozart, and Juliette Geisha with it, and also tried extending the variable-speed function to iced pour-over scenarios, comparing it with the V60. This article provides a complete record of three sets of brewing parameters, flavor performance, and detailed issues found during use, for coffee enthusiasts' reference. [more…]

Whether to add a filter paper to a moka pot depends on what problem you're trying to solve. Placing filter paper at the bottom of the basket mainly helps distribute hot water more evenly, reduces clogging, and makes it easier to knock out an intact puck for simpler cleaning; placing it on top of the puck increases filtration precision, reduces off-flavors from fine particles, gives a cleaner taste, and slightly increases extraction pressure. Front Street Coffee ran comparisons using a classic blend and found that adding filter paper at the bottom has very little effect on flavor but offers a clear cleaning advantage. This article explains the principles, practical effects, and suitable scenarios for each placement method, helping you choose according to your needs. [more…]

As an essential coffee device in Italian households, the moka pot has been easily extracting rich coffee with 1-2 bar of pressure since its invention by Bialetti in 1933.

Among pour-over coffee equipment, cone-shaped drippers and flat-bottom drippers are two completely different choices. The cake dripper gets its name because its filter paper resembles baking paper, and its flat bottom brings extraction characteristics opposite to those of the V60: the coffee bed is thinner and more uniform in depth, pouring does not require deliberately controlling the range, and even beginners can easily brew a balanced and full-bodied cup of coffee. Of course, the relatively slow flow rate also requires us to make targeted adjustments in our parameters. In this article, Front Street will analyze the structural principles and flavor tendencies of the cake dripper, and share a specific method for brewing Ethiopian Hamashu with the Origami dripper, including coffee dose, water temperature, grind size, and staged pouring technique, to give you a comprehensive understanding of the advantages and disadvantages of flat-bottom drippers.

Front Street Coffee has previously introduced the concave-designed conical Ice Pupil dripper, and today we bring its younger sibling—the Ice Pupil B75. This flat-bottom dripper, co-designed by Li Jinlong and Timemore in 2022, gets its name from the Basket and its 75° angle. It features a 5cm extra-large drainage hole and a thick-walled heat-retaining structure, bringing the coffee bed closer to a cylindrical shape, allowing for smooth and even drainage. Front Street conducted both hot and iced brewing tests using Ethiopian 74158 Santa Vini and Emerald Green Label Geisha: during hot brewing, the B75 maintained a stable flow rate throughout, completing extraction in 2 minutes and 9 seconds, with prominent notes of dried mango, strawberry, and black tea, and an extremely strong sweetness; during iced brewing, it presented a balanced juice-like quality of honey, cream, and mandarin orange. The B75 is also very friendly to beginners who are not skilled at flow control, making it a powerful tool for amplifying the strengths of sweet beans. [more…]

Many people notice a layer of fine black powder at the bottom of the cup after finishing a latte or espresso, and sometimes dark particles float at the bottom of an iced latte as well. Is this actually normal? Does it affect flavor or health? In fact, this sediment consists of ultra-fine particles that pass through the filter basket holes during espresso extraction. A trace amount is normal, but if a large amount of grounds is visible to the naked eye, it means something has gone wrong in the extraction process. This article starts with where these fine particles come from, analyzes possible factors such as grinding, the portafilter basket, and barista technique, and offers practical solutions like adjusting the grind setting, switching baskets, and adding a paper filter, to help you enjoy a cleaner cup of coffee.
