Why does the espresso puck stick to the group head? How does the pressure relief function prevent the risk of machine explosion?

When making espresso, a puck sticking to the group head is an embarrassing situation many baristas dread most. Behind this is actually a close relationship with the espresso machine's pressure relief function—after extracting the coffee, the machine needs to release the residual pressure in the portafilter basket, otherwise removing the handle could cause the machine to explode. So why exactly does the puck get stuck? And how does the pressure relief valve work? Front Street Coffee will explain these issues clearly in one go, from principles to practical operation, helping you understand and avoid this kind of "work nightmare." [more…]

Why Does the Puck Stick to the Brew Head After Espresso Extraction? An Analysis of Operating Details and Causes

When using an espresso machine to extract espresso, many people have encountered the situation where the puck sticks firmly to the brew head.

Front Street, based on an actual encounter, tasted the coffee extracted while the puck was stuck and analyzed the various operational factors that lead to this phenomenon, including the dose, the timing of removing the portafilter, and bumping before extraction, to help everyone more clearly understand the real reasons why the puck sticks to the brew head.

Why Does a Coffee Grinder Cause Flying and Sticking Grounds? Static and Oils Are the Main Causes—A Few Practical Tips to Fix It

When grinding coffee beans, have you ever encountered coffee grounds splattering everywhere or sticking to the dosing cup or the exit chute? There are usually two reasons behind this: the oils seeping out of dark-roasted beans, and static electricity in a dry environment. Dark-roasted beans have a loose structure, and as carbon dioxide is released, oils seep out along with it, making the ground particles prone to clinging to the cup walls; static electricity, meanwhile, causes fine particles to stick to the grinder's exit chute, reducing the actual amount of grounds you get. Some newer electric grinders come with anti-static plates, but many small electric grinders and hand grinders don't have this design. The Little Fuji grinder that Front Street Coffee once used had long-standing problems with flying grounds and retained grounds, and the bottom of hand grinder burrs often end up covered in coffee grounds. In addition to analyzing the causes, this article will also share a simple anti-static method of stirring coffee beans with a wet spoon, and remind you of the risks and precautions involved, helping you reduce waste and improve your grinding experience.

Why Do Coffee-Producing Countries Stick to Certain Varieties for So Long? A Panoramic Analysis from the History of Leaf Rust to Laboratory Breeding

When you shop for coffee beans, have you ever noticed that certain origins always seem to grow just a few fixed varieties? Brazil, for instance, is dominated by Bourbon, while Jamaica Blue Mountain is inseparable from Typica.

That devastating disease at the end of the 19th century forced many producing countries to turn to research on disease-resistant new varieties, leading to the establishment of national coffee research institutes. This article will walk you through the origins and development of common laboratory varieties such as Catuai, SL28, SL34, Ruiru 11, and H1, and how they became the mainstays of today's producing regions.

Turning Coffee Grounds into Three-Dimensional Artworks: Filipino Creator Liva Blando's Coffee Grounds Art Practice

Every day after brewing coffee, a large amount of coffee grounds is often thrown away directly, but Philippine nursing student Liva Blanda discovered the possibility of creation from them. Inspired by her father's coffee-drinking habit, she turned coffee grounds into wonderful and lovely paintings, some of which even have 3D effects. Her creation requires not only creativity but also carefulness and patience: first sketch with a pencil, then use a small bamboo stick to move the coffee ground particles into the corresponding positions, and finally add real objects such as twigs, leaves, or petals to complete the key step. To extend the preservation time, Liva also uses glue to fix them, which increases the difficulty but also makes the works more stable. Her practice reminds us that as long as we carefully observe life and consult our elders, seemingly discarded items can also be reasonably used, adding enjoyment to daily life. [more…]
