If the integration is insufficient, the surface will show an uneven "dirty" look, and it may even affect the taste. This article will systematically explain how to make the surface of latte art clean and tidy from three dimensions: the quality of the milk foam and crema, the integration technique, and the pouring height, and will also answer what kind of milk should be chosen for latte art. Drawing on practical experience, Front Street Coffee provides you with actionable improvement solutions to help you make beautiful and delicious lattes at home. [more…]

To enjoy a cup of pour-over coffee with a fresh flavor and clean mouthfeel, there are actually discernible guidelines when choosing beans. The degree of roast, the processing method, and the terroir of the growing region are the three key factors that determine the direction of a coffee's flavor. A light roast preserves more organic acids and delicate aromas, while the washed process makes the fermentation level of the coffee beans more controllable, and the regions of Africa and Central and South America are especially concentrated sources of fresh-flavored beans. Based on Front Street's bean-selection experience, this article lays out a practical approach to choosing coffee beans with high cleanliness and a fresh flavor, and recommends specific qualifying beans such as Front Street Yirgacheffe·Gedeb and Front Street Wander Estate·Washed Geisha, suitable for both pour-over and cold brew preparation.

Luckin Coffee is known for its tidy stores, but recently many employees have spoken out on social media, reporting that quality control inspection standards are overly meticulous, with strict deductions even for hard-to-reach corners such as pipes along walls and dust on chandeliers. From rusted screws on paper towel dispensers to loose threads on aprons, the tediousness of the inspection items has sparked complaints from workers, who bluntly say they are expected to "clean the prep area like an operating room."

Have you ever suddenly found yourself out of filter paper while brewing coffee at home—does that leave you completely stuck? Actually, that's not the case. Filter paper is indeed indispensable for pour-over and other drip-style extractions, but if you switch to immersion extraction, its role becomes optional. Immersion extraction means fully steeping the coffee grounds in water. The extraction efficiency gradually slows as the water temperature drops and the concentration difference decreases, so over-extraction is less likely, the margin for error is higher, and the mouthfeel is fuller. Even without any filtering tool, as long as you master a few small techniques, you can still brew a clean, grit-free cup of coffee. In this article, Front Street Coffee will use a native variety from Ethiopia's Kafa Forest, relying on just two containers and a spoon, to test the entire process of filter-free immersion extraction, and compare the core differences between immersion and drip methods.
