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…]

In discussions about pour-over coffee, the 1:16 coffee-to-water ratio is often dubbed the "golden ratio," so some friends are surprised that Front Street Coffee uses 1:15 in its daily routine. Behind this lies the Golden Cup extraction theory—Dr. Lockhart's research indicates that most people prefer coffee with a concentration between 1.15% and 1.35%, and an extraction yield between 18% and 22%. The Golden Cup extraction chart visually illustrates the relationship between coffee-to-water ratio, concentration, and extraction yield, and 1:16 happens to be a ratio that easily falls within the ideal range. However, the Golden Cup standard is only a reference, not an absolute rule: tastes vary from person to person—1:14 or even 1:10 suits those who prefer a strong brew, while 1:17 to 1:20 is better for those who enjoy a lighter taste. Front Street Coffee chooses 1:15 to make the flavors more concentrated and the mouthfeel more substantial, and it adjusts the water temperature and grind based on the roast level. This article will provide a complete analysis of the origin of the golden coffee-to-water ratio, the true meaning of Golden Cup extraction, and Front Street Coffee's specific brewing parameters for beans such as Huakui, Geisha, Queen's Estate, and Golden Mandheling.

Without adding sugar or milk, how to hand-brew a delicious and distinctive cup of coffee is a difficult challenge for many enthusiasts just starting out in coffee. Pour too much water and the coffee will be weak; pour too little and it will be very strong and harsh on the throat. Therefore, you must pay attention to the coffee-to-water ratio. So exactly how much water should be used to brew a cup of coffee? The coffee-to-water ratio is probably what every [more…]

Many coffee enthusiasts have heard of the "golden ratio" for espresso—using a dose roughly equal to the basket's capacity, and extracting twice the dose weight in liquid weight within 25 to 30 seconds. However, when everyone strictly follows the 1:2 brew ratio to dial in, they find that not only does it consume a large amount of coffee beans, but the taste is also hard to reach an ideal state. So, must espresso extraction stick firmly to the 1:2 brew ratio? The answer is no. This ratio is just a general reference standard, helping us extract a delicious espresso with appropriate concentration and a reasonable extraction yield. The truly effective dialing-in method is to remove the restrictions on dose and liquid weight, and treat them as adjustable variables as well. This article will explain this flexible adjustment approach in detail for you. [more…]

Many friends who are just getting into espresso have heard the saying: the brew ratio for espresso should be controlled at 1:2, for example, 18 grams of coffee grounds extracted into 36 milliliters of espresso. This ratio is often called the "golden ratio," but is it really the only standard? Actually, it is not. The brew ratio determines the strength of the coffee, and the strength in turn directly affects how the espresso performs when drunk on its own or paired with milk. This article centers on the relationship between brew ratio and actual extraction, explaining why 1:2 has become a commonly used reference value, and why ratios such as 1:1.5 and 1:2.5 are equally viable, helping coffee enthusiasts understand espresso extraction parameters more flexibly. [more…]

How much water should 15 grams of coffee grounds actually be paired with? How can a single-serving pour-over brew a stable and delicious cup? This article starts from the 1:15 coffee-to-water ratio long used by Front Street Coffee, explaining the difference between the coffee-to-water ratio and the water-to-coffee ratio, why the brewed coffee liquid is not 225 milliliters, the relationship between 1:15 and the Golden Cup extraction range, and why this ratio is reliable enough for most coffee beans. At the same time, the article also fully breaks down the specific steps of three-stage pouring, including blooming, the water volume for each stage, changes in the liquid level, and the shaking and blending after brewing ends, helping you better bring out floral aromas, fruity acidity, and rich layers with pour-over. [more…]

In pour-over coffee, the coffee-to-water ratio is a parameter that seems simple yet has far-reaching effects. How much hot water you pour in not only directly determines the strength of the coffee, but also influences the final flavor profile by changing the extraction time and the total amount extracted. The larger the coffee-to-water ratio, the less water used, and the stronger the coffee; the smaller the coffee-to-water ratio, the more water used, and the weaker the coffee—but things are far from that simple. Through measured data, Front Street Coffee has found that merely adjusting the coffee-to-water ratio also causes the extraction yield to change noticeably. So how exactly should you find the coffee-to-water ratio that suits you? And how should you balance strength and extraction yield? Starting from Front Street's experiments, this article will break down the coffee-to-water ratio's effect on extraction one by one and offer adjustment ideas to help you make wiser choices in your daily brewing.

Brewing a good cup of coffee, the coffee-to-water ratio and extraction yield are core parameters that cannot be avoided. The SCA Golden Cup extraction theory gives an ideal range of 18%-22% extraction yield and 1.2%-1.45% concentration, but many enthusiasts easily misunderstand it as "as long as you copy the Golden Cup coffee-to-water ratio, you will definitely brew a good cup of coffee." This article starts with a simple calculation of the coffee-to-water ratio, guides you to understand the meaning of the Golden Cup extraction range, clarifies the boundary between over-extraction and under-extraction, and explains the true value of learning the Golden Cup theory—not rigidly sticking to a certain ratio, but using it to adjust brewing variables and more flexibly approach the flavor you want. Front Street Coffee also shares related products and brewing ideas in the article for coffee enthusiasts' reference. [more…]

Many people new to espresso often run into this confusion: they follow the popular online formula of 18g of grounds yielding 36ml of liquid, yet the coffee tastes sharp and stings the tongue—clearly under-extracted—and they have no idea whether to adjust water temperature, pressure, water volume, or grind. In fact, dialing in espresso isn't complicated; you just need to focus on three core parameters: dose, brew ratio, and the interplay of time and grind. Dose and ratio usually don't change much—what really needs repeated fine-tuning is the grind setting. Drawing on Front Street's practical experience, this article explains why 1:2 is considered the golden ratio for espresso, how to use the roughly 30-second extraction window to judge whether your grind is right, and how to make precise corrections through dose and yield when the flavor goes off—helping beginners quickly build a clear, workable approach to espresso extraction. [more…]

The same coffee beans, the same grind size and dose, and merely adjusting the espresso brew ratio can make a latte, an americano, and an espresso take on completely different flavor directions. Taking Front Street Coffee's specialty blend of Colombian and Brazilian beans as an example, 20 grams of grounds were extracted at three ratios—1:1, 1:1.5, and 1:2—to taste the differences in mouthfeel among espresso, latte, and americano one by one. The actual test found that: a smaller-ratio espresso has a more pronounced acidity but noticeably sweeter when made into a milk coffee; a larger-ratio espresso easily develops over-extracted woody and smoky notes; 1:1.5 performs best in terms of layering and balance. The article also shares ideas for selecting espresso beans and the characteristics of Front Street's classic espresso blend. [more…]

The coffee-to-water ratio for pour-over is a core question every enthusiast will face. Where exactly does the 1:15 ratio come from? Does it truly conform to the SCA Golden Cup extraction standard?
