In coffee brewing, the choice of measuring tools may seem like a minor matter, yet it directly affects consistency in the cup. A measuring spoon is convenient, but it measures volume rather than weight; due to differences in variety, cultivation, and roasting, the same level spoonful of different coffee beans may scoop out 9g or 11g, an error large enough to change the direction of the flavor. Front Street Coffee once conducted an experiment with Geisha Village Red Label Geisha: with water volume and other parameters unchanged, adjusting the dose by just 1g produced noticeable differences in concentration and extraction yield. This article will use experimental data to explain why electronic scales have become the first choice of coffee shops, and to show why measurement accuracy must be even higher under pressurized espresso extraction.

Many friends who are just getting into pour-over coffee, in order to save money, often skip tools like electronic scales and thermometers, and instead use spoons they already have at home to estimate their coffee dose. But spoons vary in size and depth, and the roast level of the coffee beans also affects density, so there is no uniform answer to how many grams a single spoon holds. This time, Front Street Coffee specifically gathered four common types of spoons—a porcelain soup spoon, a small stainless steel spoon, a cupping spoon, and a promotional bean scoop—and separately weighed light roast, medium-light roast, medium-dark roast, and dark roast coffee beans before and after grinding, compiling a complete set of data, and teaching you how to convert, based on roast level, the number of scoops needed for close to 15 grams of coffee, so that even without an electronic scale you can still roughly control your coffee dose.

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 Golden Cup extraction theory, extraction yield and concentration are the two core metrics for assessing the flavor state of coffee. However, coffee that falls within the ideal range is not necessarily delicious, and coffee outside the range is not necessarily undrinkable—the key lies in how to use these two values to help adjust the brewing plan. From the perspective of Front Street, this article first clarifies the basic definitions and ideal ranges of extraction yield and concentration, then explains in detail how to use two sets of concentration measuring tools, and finally uses the Santa Vini anaerobic natural beans as an example to fully demonstrate the entire process from weighing the liquid weight to plugging it into the formula to calculate the extraction yield.

When brewing pour-over coffee, if the filter basket ends up with a thick, muddy bed of grounds instead of distinct, granular particles, it often means the coffee was ground too fine, which easily leads to over-extraction. When faced with the dilemma of pre-ground coffee that cannot be made coarser, besides switching to immersion extraction, there is another distinctive approach using high concentration and low extraction—the mud flow. It uses extremely fine grinding combined with agitation to rapidly dissolve flavor compounds in a short time, then dilutes with hot water, resulting in coffee with a normal extraction yield and full flavor. In this article, Front Street will explain in detail the principles and specific operating parameters of the mud flow, helping you easily tackle the problem of coffee grounds that are too fine.

When ordering at a coffee shop, have you ever been confused: if you extract 36ml of espresso from 18g of coffee grounds, should that count as 1 shot or 2 shots? This seemingly simple question actually involves the evolution of measurement standards in the coffee industry. In the early days, 1 shot referred to 30~36ml of coffee liquid extracted from 7~9g of grounds, while today the mainstream approach has changed to extracting 36ml of liquid from 18g of grounds. Is the measurement object the dose of grounds or the volume of liquid? Today, Front Street Coffee will start with the origin of the word "shot" to help you thoroughly sort out the logic for determining single versus double espresso, so you will no longer be confused when ordering or making coffee.
