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.

Many friends who are just getting into pour-over coffee often confuse the coffee-to-water ratio with the coffee-to-beverage ratio, and as a result, the coffee they brew always tastes different from what they expected. In fact, although these two concepts differ by only one word, their meanings are completely different, and they cannot even be converted directly on an equal basis. Today, Front Street will explain these two measurement methods, first explaining what each of them represents, then clarifying how the coffee grounds' water absorption affects the final liquid weight, and offering a way to convert between the coffee-to-water ratio and the coffee-to-beverage ratio. Once you understand these, you will have a clearer direction when adjusting pour-over parameters, and it will be easier to consistently reproduce a delicious cup of coffee. [more…]

In the brewing process of specialty coffee, the coffee-to-water ratio and the coffee-to-beverage ratio are two core concepts that cannot be avoided. Many people assume they are simply different names for the same thing, but in reality their calculation methods and applicable scenarios differ significantly. This article will start from the basic definitions of these ratios, first explaining the meaning and advantages of the coffee-to-water ratio, then delving into why the coffee-to-beverage ratio cannot be directly equated with the coffee-to-water ratio, and, combined with the water absorption rate of coffee grounds, provide a practical conversion method. Once you understand these two parameters, you will have clearer direction when adjusting your brewing recipe, and it will be easier to consistently reproduce your ideal flavor performance. [more…]

In the daily practice of pour-over coffee, the coffee-to-water ratio and the coffee-to-beverage ratio are two concepts that are often mentioned but easily confused. The former refers to the ratio of coffee grounds to the amount of water poured, while the latter measures the relationship between the coffee grounds and the weight of the final brewed coffee liquid. Since coffee grounds absorb about twice their own weight in water during extraction, there is a convertible correspondence between these two ratios. Understanding their differences not only helps in choosing the appropriate measurement method for different brewing scenarios, but also enables coffee enthusiasts to precisely control the extraction results. This article will systematically sort out the definitions of the coffee-to-water ratio and the coffee-to-beverage ratio, the conversion logic, and their respective applicable occasions, and combine them with the practical experience of Front Street Coffee to provide readers with clear operational guidance.

In the parameter system of pour-over coffee, the coffee-to-water ratio and the coffee-to-liquid ratio are two parallel measurement logics. The former relies on a digital scale to precisely control the amount of water poured, while the latter judges the final volume of coffee liquid through the markings on a serving carafe. Many classic utensils, such as the Kono serving carafe and the Hario Cloud server, have hidden scale markings that correspond to specific coffee dose designs. The coffee-to-liquid ratio is more flexible when dealing with clogged drippers and deep-roast foam handling, while the coffee-to-water ratio excels in the precision of staged pouring information. The two can also be converted into each other: coffee grounds absorb about twice their own weight in water when saturated, so a coffee-to-water ratio of 1:15 is roughly equivalent to a coffee-to-liquid ratio of 1:13. Only by understanding this logic can reasonable adjustments be made according to different beans and utensils. [more…]

To make a decent espresso at home, you need to get three things straight: how much coffee you use, how much liquid you extract, and how fine you grind. The standard reference is a 1:2 coffee-to-liquid ratio—about 9 grams of coffee yielding 18 grams of liquid for a single shot, and 18 grams of coffee yielding 36 grams for a double, with the actual output fine-tuned to taste. As for grind size, watch the flow rate: if it runs fast, grind finer; if it runs slow, grind coarser, until the extraction time falls within the right range. The roast level of the beans also matters a lot—medium-dark roasts and darker make it easier to achieve a balanced flavor. Drawing on the real-world parameters of Front Street Coffee's classic blend, this article lays out the extraction logic clearly in one go. [more…]

Friends often tell Front Street Coffee that they've just bought a new coffee machine but don't know how to dial in a standard espresso. They don't know how much coffee grounds to use, how much liquid weight to extract, or how long it should take. And even if they follow popular extraction formulas like "use 18g of grounds to extract 36ml of coffee liquid," what they end up with [more…]

Front Street Coffee believes that after you've been working with espresso for a while, you'll certainly be familiar with the "1:2" brew ratio, because it's often hailed as the "golden ratio" for espresso and is the most commonly used ratio when extracting espresso. Brew ratio refers to the amount of coffee grounds used [more…]

The standard espresso ratio is 1:2—a single shot uses 9g of grounds to yield 18g of liquid, and a double shot uses 18g of grounds to yield 36g of liquid. When actually pulling a shot, fine-tune based on this brew ratio and the taste. The grind size for espresso is also adjusted by referencing this extraction time: if it runs fast, grind finer; if it runs slow, grind coarser, until the extraction time matches. [more…]

Latte coffee seems simple, but in reality it hides real craftsmanship. Many people follow a recipe, yet the final result always feels like it falls a bit short, and the problem often lies in parameter control. This article starts with the espresso extraction formula and the coffee-to-milk ratio formula, breaking down how to use variables such as the coffee-to-water ratio, extraction time, and milk quantity to bring a latte to a state of balanced flavor and full-bodied texture. Whether you prefer the rich chocolate notes of a dark roast or the bright fruit acidity of a light roast, the article provides corresponding adjustment approaches, and also includes a simple method for iced latte, helping you elevate your latte from "drinkable" to "delicious." [more…]

To make a decent espresso at home, the coffee-to-water ratio and grind size are two core variables you can't avoid. Standard espresso is usually based on 1:2, with a single shot using about 9 grams of coffee to extract 18 grams of liquid, and a double shot using 18 grams of coffee to 36 grams of liquid, but the actual output still needs fine-tuning based on how it tastes that day. The most intuitive way to judge whether the grind size is right is the extraction flow rate: if the liquid comes out too fast, the grind is too coarse and needs to be made finer; if the liquid comes out too slow, the grind is too fine and needs to be made coarser, until the extraction time falls within a reasonable range. Besides the parameters, the choice of beans is equally key—medium-dark roast blends or darker are more likely to achieve a balanced, stable flavor. This article will organize an actionable set of adjustment ideas around dose, ratio, grind size, and extraction time. [more…]

When it comes to combining pour-over coffee with milk, most people think of café au lait, but café au lait has a relatively low coffee concentration, and its flavor is easily diluted once milk is added, making it clearly different from an espresso-based latte. Front Street Coffee recently noticed a shop-visit video by a well-known Korean coffee blogger, in which a champion barista used a pour-over method to make a milk coffee with excellent flavor and mouthfeel. This article will focus on the extraction logic of espresso and share how to obtain a very high-concentration pour-over coffee as a base by adjusting the coffee-to-water ratio, grind size, water temperature, and stirring technique, then add milk in an appropriate ratio to create a drink that comes infinitely close to a latte.
