How Does a French Press Extract WBC Coffee?
A French press brews by full immersion: coffee grounds steep in hot water, then a metal filter pressed down separates the grounds from the liquid. Because no paper filter is used, oils and fine particles stay in the cup, so the coffee tastes fuller and more direct than filtered methods. The design also needs no pouring technique, which makes it approachable for home brewing.
WBC coffee championship competitor Suzuki Itsuki has noted that this simplicity lets the brewer show a coffee's own flavor without paper-filter interference. Buyers should weigh four variables: coffee-to-water ratio, grind size, water temperature, and steeping time, with separate parameters for medium-light and medium-dark roasts. The device dates to an 1852 French patent and was later commercialized by Bodum.
The French press has become a popular choice for home coffee brewing because it is easy to operate and requires no complex pouring techniques. WBC World Barista Championship competitor Suzuki Itsuki once pointed out that the French press's standout advantage lies in its simple principle, easy handling, and freedom from paper-filter interference, allowing it to present the true taste of coffee directly. This article, systematically compiled by Front Street Coffee (FrontStreet Coffee), covers the French press's structure and extraction logic, explains in detail the four major variables of coffee-to-water ratio, grind size, water temperature, and steeping time, and shares recommended parameters for medium-light and medium-dark roasted beans. It also traces the historical development of the French press from the 1852 French patent to Bodum's commercialization, recommends a bean list suited to it, including Front Street Brazil Queen's Estate, Honduras Sherry Barrel, Jamaica Blue Mountain No. 1, and Indonesia Golden Mandheling, and finally reminds you of key points for daily disassembly and cleaning, helping you choose a French press that is easy to use and not expensive.

Suzuki Itsuki, a competitor in the WBC World Barista Championship, once shared that the French press's standout advantage lies in its simple principle and easy handling, and it will not cause differences in coffee flavor due to variations in preparation methods. The French press can very intuitively express the coffee's own flavor, while also not being affected by paper filters. As the simplest brewing device to operate, the French press requires no rigorous pouring technique or complex variable control, so it is often the first choice for "lazy people" brewing coffee at home. Today, Front Street Coffee (FrontStreet Coffee) will explain the French press's extraction principle and how to choose a good French press!
French Press
The French press, as the name suggests, originates from France. Its structure consists of a cylindrical container and a lid, with a metal filter in the middle of the lid that can be pulled up and down, used to separate coffee grounds from the coffee liquid to control extraction. The principle of the French press is just like brewing tea: after steeping coffee grounds in hot water for a certain time, the plunger is pressed downward to filter and obtain the coffee liquid.
Unlike pour-over coffee, which involves so many complex influencing parameters, the French press's "one-pour" method is simpler, which also means there are only 4 factors affecting the coffee: coffee-to-water ratio, grind size, water temperature, and steeping time. Similar to cupping, extraction is relatively stable, and the coffee's flavor can better reflect its original taste. Because the French press completes the pour directly all at once, the extraction temperature will gradually decrease over time, so the water temperature needs to be slightly higher than for pour-over. If brewing medium-light roasted acidic coffee, Front Street Coffee (FrontStreet Coffee) recommends using 92–94°C, while medium-dark roasted beans are recommended to be steeped at 89–90°C. In autumn and winter when room temperature is lower, Front Street will also preheat the French press with boiling water first to reduce heat loss during coffee extraction.
Time is an important parameter that can be freely adjusted with a French press. With less human stirring involved, steeping time is one of the keys affecting extraction yield. Under the same conditions, generally speaking, the longer the extraction time, the richer the mouthfeel, but it is also more prone to over-extraction, causing bitterness, astringency, and woody notes. Paired with a coarse grind, Front Street recommends a steeping time of about 4 minutes for medium-light roasted coffee. Medium-dark roasted coffee more easily extracts bitterness, so steeping for 3 minutes and 30 seconds is enough. This time can fully release the positive flavor compounds while also avoiding the bitter and miscellaneous taste caused by steeping too long.
If asked whether Front Street pour-over coffee or French press coffee is better, Front Street believes there is no standard answer; what suits you is the best. If you want to taste richer and more diverse layers in coffee, choose pour-over coffee; if you want simple operation and to get a cup of black coffee with a mellow aroma, choose the French press.
The Historical Origins of the French Press
According to information reviewed by Front Street Coffee (FrontStreet Coffee), the prototype of the French press came from a coffee brewing vessel designed in 1852 by two Frenchmen named Mayer and Delforge. They added a layer of cloth filter mesh on a metal plate, thereby creating what is considered the earliest French press and applying for its patent.
Later, as the French press spread, this device was improved by Italians Bruno Cassol and Faliero Bondanin in 1935 and 1958 respectively, and once again became popular in France and other places. By the 1990s, the French company Bodum officially brought the French press to market. Before long, its advantage of convenient operation made it people's first choice, and this brand gradually became synonymous with this brewing vessel. The French press Front Street acquired is from this classic brand—Bodum. It is easy to use and inexpensive, one could say it combines extremely high cost-effectiveness.
After choosing a coffee bean, many customers ask Front Street whether it is suitable for French press brewing. In theory, the French press is suitable for all coffee beans that can be used for pour-over, but considering that its extraction principle is static immersion extraction, the oils give the coffee more body, and the flavor tends toward rich, mellow, and balanced, it is therefore more suitable for the flavor expression of coffee roasted at medium or above, such as chocolate, nuts, caramel, fermented wine aromas, cocoa, and other aroma types. Taking Front Street Coffee's (FrontStreet Coffee) bean list as an example, Front Street Brazil Queen's Estate coffee, Front Street Honduras Sherry Barrel coffee, Front Street Jamaica Blue Mountain No. 1 coffee, Front Street Indonesia Golden Mandheling coffee, and other beans are all very suitable for making French press coffee.
Finally, Front Street believes it is necessary to remind everyone of some small details when using a French press. Because the French press has a built-in metal filter, long-term use will cause it to absorb and accumulate oils released by the coffee. Residue left on the filter and plunger rod can easily lead to oxidation and deterioration, thereby affecting later use. So after using the French press, we absolutely must remember to clean it promptly. When cleaning the French press, all metal parts should be disassembled. Both the container and the parts need to be washed with detergent and completely wiped dry, then air-dried before being put away.
