FrontStreet Coffee - Pour-Over Coffee History and Grind Size Introduction. The Martin coffee pot was the earliest filter and container (or brewing utensil) separated design, marking the development of coffee powder extraction from immersion to filtration methods. Over hundreds of years, continuous innovations have been made in the filter's shape, style, and materials.

FrontStreet Coffee - The History of Pour-Over Coffee and Grind Size Introduction

The Martin coffee pot was the earliest device to separate the filter from the container (or brewing vessel), marking the beginning of the transition from immersion to filtration coffee extraction. Over hundreds of years, innovations in filter shapes, styles, and materials have continued to emerge. More specialized flannel handles appeared, as did combinations of ceramic or metal resin filter cups with paper filters. It can even be said that the popular coffee drip bag style (invented in Japan) bears the influence of the Martin coffee pot. With increasing extraction research and technological advancements, people have realized that different specific gravities during filtration and immersion greatly affect flavor, leading to increasingly detailed requirements for pour-over coffee conditions. The refinement of pour-over kettle production and the gradual formation of pour-over techniques have also developed.

Many friends who consult with us about pour-over coffee have many equipment questions. We will introduce some commonly used equipment to everyone, and we recommend that everyone try them out in our classroom before purchasing. This way, you can achieve better matching and save quite a bit of money! Essential equipment: pour-over kettle, electronic scale, filter cup, filtering material, coffee cup, grinding equipment.

Beginner's Pour-Over Solution

For coffee brewing, first we need to determine the water-to-coffee ratio. The water shouldn't be too much or too little. The grind size is recommended to be cupping grind, and each grinding device will have a recommended grind setting. Determine the water temperature and total brewing time. Water temperature: 93°C, 18g of coffee with 288ml of water, total time is 2 minutes.

We all know that the factors affecting pour-over coffee are multifaceted, and grind size is one of them. Grind size generally refers to the size of coffee particles. To put it simply, the size of coffee particles affects the contact time between coffee and water.

Under the same parameters, the finer the particles, the higher the extraction rate. The finer the coffee is ground, the larger the contact area with water, resulting in a higher concentration of dissolved coffee. Conversely, the coarser the coffee is ground, the smaller the contact surface area with water, resulting in a lower concentration of extracted coffee.

Previously, someone asked the editor, "If I want to extract more substances and more coffee flavors, can I grind the coffee finer?" It's not impossible, but you should know that when making pour-over coffee, if the coffee is ground finer, there will be more fine powder, which easily clogs the filter paper holes. Once water has difficulty passing through the filter paper, the coffee extraction speed slows down, and the extraction time is prolonged. This leads to coffee that is bitter and complex, difficult to swallow. Of course, if you're a pour-over expert who knows how to utilize fine powder well, that's another matter~

However, there is one device that requires relatively fine powder, and that's the espresso machine for concentrated extraction! Espresso extraction is coffee extracted in a short time through high pressure. Water quickly passes through the coffee powder, thereby extracting the aroma and flavor of the coffee.

Knowledge Point: Pour-over coffee is typically made by hand with single-origin, single-region coffee beans. Connoisseurs even roast and grind their own beans.

In short: FrontStreet Coffee is a dedicated research center for coffee, happy to share coffee knowledge with everyone. Our sharing is completely without reservation, just to let more friends fall in love with coffee. Moreover, we hold three low-discount coffee events every month. The reason is that FrontStreet Coffee wants to let more friends drink the best coffee at the lowest price, which has been FrontStreet Coffee's principle for the past 6 years!
