Espresso Machine Cleaning Guide | How Often Should an Espresso Machine Usually Be Cleaned? What Are the Steps to Clean a Semi-Automatic Espresso Machine at Home?

Moka Pot Grind Size: Pair It with the Right Roast Level
Coffee brewed in a moka pot can have bright fruity notes, or it can show the depth of cocoa and nuts. An important clue that determines the difference is the roast level of the coffee beans.

A Complete Guide to Coffee Defects: Ten Common Types, Causes, and Identification Methods Illustrated
The content of defective beans directly affects coffee quality and grade classification. Taking Brazil as an example, the local system uses a "deduction method," grading based on the number of defective beans per 300 grams of main beans. In addition, coffee usually requires hand sorting during processing, and only by fully mastering the types and characteristics of defective beans can they be effectively removed. So exactly how many types of defective beans are there? This article will use illustrated explanations to introduce ten common defective beans one by one, including shell beans, stones, moldy beans, fermented beans, dead beans, immature beans, shell beans, insect-damaged beans, black beans, and cocoa beans, explaining their causes, appearance characteristics, and negative effects on coffee flavor, laying the foundation for subsequent learning about defective bean selection.

The Flavor Clock After Opening Dark Roast Beans
When dark-roasted coffee beans first leave the roaster, the aroma is often very pungent, and the cup tends to show sharp smoky notes, diffuse bitterness, and a sweetness that isn't cohesive enough. The reason is that after roasting, the beans are still releasing carbon dioxide, which affects the state of the coffee bed and the water flow. When buying beans, check the roast date first, then plan your drinking schedule—this matters more than just [more…]
The Flavor Peak of Espresso: Understanding Roast Dates, Degassing Cycles, and Daily Sealed Storage
Espresso extraction is extremely sensitive to the state of the carbon dioxide inside the coffee beans, and the completion of roasting does not mean the beans immediately reach the balance point for aroma release. Freshly roasted coffee beans are packed with a large amount of gas inside. If pressurized extraction is carried out right away, the water flow is easily obstructed by bubbles, leading to uneven extraction and bringing out too many off-flavors. Understanding [more…]
