When brewing pour-over coffee, you've dialed in the temperature and grind size, yet the taste still falls short of expectations? The problem likely lies in the coffee-to-water ratio. The amount of water directly affects the flavor expression and mouthfeel layers of the coffee: too little water makes it overly heavy, with flavors compressed together and hard to distinguish; too much water makes it overly thin, even like a cup of water with a hint of coffee flavor. This article starts from the theoretical range of the Golden Cup extraction, combines actual brewing tests across light, medium, and dark roasts, analyzes how three coffee-to-water ratios—1:13, 1:15, and 1:17—perform differently on various beans, and explains why light-roasted beans suit a longer ratio while dark-roasted beans are better with a tighter ratio. Finally, it will explain how the coffee-to-water ratio should be adjusted as the brewing device changes. [more…]

When making coffee, the coffee-to-water ratio is the first brewing factor we need to determine. So what is the standard coffee-to-water ratio? The answer is: the golden ratio is 1:18, meaning every 1g of coffee corresponds to 18ml of water. This ratio was derived by the American Coffee Association through surveys and extensive practice. But [more…]

Among the many variables in pour-over coffee, the coffee-to-water ratio is often overshadowed by grind size and water temperature, yet its influence on the final flavor profile cannot be ignored. Using the Blue Label Geisha from Panama's Hacienda La Esmeralda as a sample, Front Street Coffee fixed the grind size, water temperature, and brewing technique, changing only the coffee-to-water ratio, and conducted comparative brews with four parameter sets: 1:15, 1:16, 1:17, and 1:18. By recording the extraction time and flavor performance of each cup, the differences in coffee concentration, complexity, sweetness, and aftertaste under different ratios were analyzed, offering a reference for ratio selection when brewing flavor-rich beans like Geisha in daily practice.

In the practice of pour-over coffee, "cutting off" the brew is a technique that is often mentioned. Many enthusiasts believe that the tail-end coffee liquid carries bitterness, and so habitually remove this portion at the end of brewing. However, cutting off the brew is not a universal key—improper use can instead destroy the coffee's complete flavor. From the perspective of Front Street, this article takes a deep dive into the dissolution patterns of bitter substances, explains why the tail end does not produce negative flavors under reasonable parameters, and distinguishes in detail between the two concepts of coffee-to-water ratio and coffee-to-liquid ratio, while also sorting out the two scenarios in which cutting off the brew truly applies—actively incorporating the cutoff into the brewing framework, and being forced to cut off due to clogging. By understanding these principles, coffee enthusiasts can use the cutoff more scientifically and improve their brewing quality. [more…]

When brewing pour-over coffee, Front Street Coffee insists on using a 1:15 coffee-to-water ratio—why is that? Was this result arrived at by chance, or was it derived from various brewing experiments based on data? In this article, Front Street will explain why. [more…]

Among the many variables in pour-over coffee, the brew ratio is often overshadowed by grind size and water temperature, yet the amount of water directly determines the direction of the final cup's flavor. Front Street Coffee used a washed Butterfly with 70% Geisha content as a sample and, while keeping grind size, water temperature, and brewing technique constant, conducted comparative brews using four brew ratios: 1:15, 1:16, 1:17, and 1:18, recording the extraction time and flavor performance of each ratio one by one. Starting from actual brewing data, this article will analyze how different brew ratios affect the concentration, complexity, and aftertaste of coffee, helping coffee enthusiasts find the brew ratio that better showcases the characteristics of flavor-rich beans like Geisha. [more…]

What exactly should the coffee-to-water ratio for pour-over coffee be?

Many coffee enthusiasts habitually use safe powder-to-water ratios like 1:15 or 1:16 in their daily pour-over brewing. Front Street also often recommends such parameters to beginners. However, once a fixed brewing pattern of fixed coffee dose with fixed water volume is established, even if the dose differs by only one or two grams, the pouring water volume is often locked in by inertia, causing the actual powder-to-water ratio to quietly shift. The powder-to-water ratio directly relates to extraction yield and concentration, and these two in turn determine the flavor and mouthfeel of the coffee. This article uses a clever cup immersion extraction experiment, brewing 14g, 15g, and 16g of Front Street Yirgacheffe Red Cherry with the same 225ml hot water, measuring concentration and tasting flavor differences, to illustrate the importance of adjusting water volume in sync when fine-tuning the coffee dose, and to remind that when the dose difference exceeds 5g, grinding, brewing technique, and dripper also need to be adjusted in [more…]

Have you ever run into this problem: the same pack of drip bag coffee, yet when someone else brews it, the aroma fills the air, while yours comes out as weak as plain water? The issue mostly lies in the parameters and technique. Although drip bag coffee has a low barrier to entry, to brew a rich, full-bodied flavor, you must nail down the three core variables: water temperature, coffee-to-water ratio, and extraction time. This article compiles three practical tips: the first is to adjust the brewing parameters to raise the extraction yield; the second is to dig a small hole in the center of the coffee bed to solve the uneven extraction caused by the overly thick layer of coffee grounds in the drip bag; the third is even more direct—pour the brewed coffee back and steep it again to remedy under-extraction. At the end of the article, there is also a complete brewing demonstration of Front Street Coffee Ethiopia Huakui drip bag, from a 1:15 coffee-to-water ratio to a four-stage pour, guiding you step by step to brew a great cup of coffee with strawberry and citrus notes.
