If your moka pot coffee won't come out after heating, or suddenly erupts in a violent spray, you're not alone—many enthusiasts have run into this problem. What's really behind this phenomenon is closely tied to the pressure in the lower chamber: as the water heats up, it produces steam, and the steam compresses the space to create a pushing force that drives hot water through the coffee bed to become coffee liquid. The stronger the pressure, the more forceful the flow, and when it exceeds what the pot body can withstand, it splashes. So which practices lead to abnormal pressure? And how should you adjust to keep the flow steady and smooth? This article analyzes the causes one by one from four angles—water volume, coffee grind size, bean roast level, and flame intensity—and offers specific, actionable ways to improve. It also recommends espresso blends suited to moka pots to help you make coffee with rich crema and a full-bodied taste. [more…]

In recent years, more and more coffee enthusiasts have chosen to buy their own espresso machines at home, starting with espresso and gradually mastering the preparation of drinks like lattes, latte art, and dirty coffee. Recently, a netizen tried to recreate the butter latte commonly seen in coffee shops at home. To skip the wait for butter to soften at room temperature, they had a sudden idea: put a block of butter directly into the portafilter and tamp it together with the coffee grounds for extraction. This method sparked a nationwide copycat challenge, but the results often ended in failure—the butter was squeezed into thin strips by the pressure and shot out from the bottomless portafilter, coffee liquid splattered everywhere, and the countertop was left in a mess. Onlookers joked that the espresso machine had switched careers to become a pasta maker. This article fully documents the process of this creative experiment, the real feedback from netizens, and warm reminders from experienced individuals. If you're also tempted to try it, you might want to first read this compilation by Front Street Coffee before making a decision. [more…]

When making espresso, have you ever encountered a situation where the flow rate of the coffee liquid alternates between fast and slow, the stream splits, or it even sprays? This is very likely the work of "channeling." Channeling refers to water in the coffee puck bypassing dense areas and quickly passing through paths of lower resistance, creating an imbalanced state in which localized over-extraction and under-extraction coexist. This article will start with the normal extraction performance of a bottomless portafilter, explain in detail the causes of channeling, its specific effects on espresso flavor and quality, and share how to reduce this problem by adjusting operations such as distribution and tamping. At the same time, the article will also mention Front Street Coffee's recommendations for related equipment and bean selections, helping coffee enthusiasts understand and address channeling more intuitively.
