The flavor expression of pour-over coffee depends to a large extent on the grind size setting. If the particles are too coarse, extraction is insufficient and the taste is thin; if too fine, over-extraction easily occurs and bitterness becomes prominent. So what range should pour-over coffee particles actually be controlled within? Different grinders have inconsistent scale standards, so how can this be expressed in a unified way? Starting from the principles of extraction, this article sorts out the mutual influences among coffee-to-water ratio, water temperature, time, and grind size, and introduces the method used by Front Street Coffee of measuring grind pass-through rate with a 0.85 mm standard sieve, giving the basic reference standard of an 80% pass-through rate to help coffee enthusiasts quickly find a suitable grinding baseline when facing different beans and equipment.

Beyond pour-over, there is another brewing device that is highly sought after by enthusiasts for its exceptional degree of freedom: the AeroPress. It was developed over twelve years by Alan Adler, founder of the Aerobie brand, and officially launched in 2005. AeroPress extraction combines both immersion and pressure mechanisms, and operationally splits into two paths: upright (standard) and inverted brewing, with virtually all parameters freely adjustable. It is precisely this openness that spawned a small friendly competition initiated by Tim Wendelboe in 2008, which gradually grew into a world-class event. This article will take you through the origins of the AeroPress, and include a universal inverted brewing recipe shared by Front Street Coffee, tested with Kenya Asalia beans. [more…]

The French press may seem simple, yet it has a tortuous history spanning three centuries. As early as 1852, a joint patent titled "Piston-Filter Coffee Device" had already sketched out its prototype; it was not until the 1930s, after a Milan company improved the design and registered a patent, that the French press gradually entered the public eye. It was once widely criticized for "coffee like mud," and was even misread by dictionaries as an exercise for biceps. Today, the French press has become a brewing tool highly praised by coffee enthusiasts worldwide. This article will comprehensively trace the invention timeline of the French press, key figures, and improvement milestones, and include standard immersion brewing instructions, while also retaining relevant product recommendations from the Front Street brand for readers' reference.

There are countless pour-over coffee brewing methods, but the core variables that truly determine flavor are simply grind size, water temperature, and the coffee-to-water ratio. Yet these seemingly simple parameters and circular pouring make it hard for many people to consistently reproduce a good cup of coffee. Machines are naturally superior to humans in consistency—does this mean baristas will eventually lose their jobs? Front Street has a bold prediction: mechanized production roles may be replaced, but baristas who truly understand brewing logic will move behind the scenes, responsible for formulating and adjusting plans. This article starts from standard brewing methods and explores the relationship between technique, understanding, and the future of baristas. [more…]

When brewing pour-over coffee, grind size is often the key variable that determines the direction of flavor.
