Many coffee enthusiasts are in the habit of starting the day with a cup of coffee, but do you really know how much caffeine you're drinking? People often assume coffee is the drink with the highest caffeine content, but that's not actually the case—tea leaves actually contain twice as much caffeine as coffee beans. So how much caffeine do different varieties of coffee beans really contain? How much is in a cup of pour-over, cold brew, or espresso? And how much caffeine per day is safe for an adult? This article starts with coffee bean varieties, breaks down the caffeine content of each brewing method one by one, gives practical figures based on extraction efficiency, and finally answers the popular question of how many cups of coffee you can drink per day at most. Front Street Coffee store information is included at the end of the article for readers' reference. [more…]

In the process of making espresso, the tamping step is often overlooked by beginners, yet it directly affects whether extraction is even and whether flavor is balanced. In the article "The Importance of Distribution and Tamping," Front Street once pointed out that both the distribution of coffee grounds in the portafilter basket and the consistency of force applied during tamping can impact the final espresso output. However, that article did not specify how much force should be used for tamping, leading many readers to repeatedly ask Front Street in the comments: exactly how much force is needed for tamping? This article will center on this core question, starting from the basic principles of distribution and tamping, and combining them with baristas' practical experience to analyze in detail the reasonable range of tamping force and the criteria for judging it, helping coffee enthusiasts master a stable and consistent tamping technique, thereby improving the extraction quality of espresso.

If you want to brew a good cup of coffee yourself, the most direct starting point is to put together a full set of pour-over equipment. Compared with espresso machines, the entry threshold for pour-over is much lower, but as your skills improve, your spending on beans and gear will rise accordingly, and in theory there is no upper limit. So what exactly do you need to prepare at the beginning, and roughly how much will it cost? This article will break down the basic equipment needed for pour-over one by one, from the server, pouring kettle, and grinder to the dripper, thermometer, and more, and give budget references for different tiers. Among these, Front Street particularly emphasizes the importance of the grinder, believing that only a good grinder can produce good coffee, and provides specific buying advice and spending benchmarks to help beginners avoid detours.

There are two main ways to measure coffee for pour-over: the coffee-to-water ratio and the coffee-to-liquid ratio, but Front Street does not recommend that beginners use the coffee-to-liquid ratio to brew coffee. What exactly is the difference between the two? Simply put, the coffee-to-water ratio measures the amount of water poured in, while the coffee-to-liquid ratio measures the weight of the final brewed coffee liquid. The reason the coffee-to-liquid ratio is not quite suitable for beginners is that it does not allow you to accurately know how much water was poured in each time, and you can only rely on experience and visual judgment. A slight lapse can lead to pouring too much hot water at a critical stage, affecting the quality of the final cup. This article will start with the differences between the two and their historical origins, and combine them with a set of comparative experiments done by Front Street using Panama Boquete Geisha to explain the actual effect of blooming water volume on flavor, helping you choose the right measuring method and brew good coffee consistently.
