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…]
