Which beans work well for French press coffee brewing?

A French press suits immersion coffee brewing, so nearly any bean works, but medium and medium-dark roasts with chocolate, nut and caramel notes hold up well against the fuller body. The metal mesh keeps more oils and coffee particles in the cup than a paper filter, so the result is heavier and rounder while still showing the bean's own character.

The press dates to France around 1850 and started as a tea tool before grounds were tried in it. Immersion time is the main variable: longer steeping dissolves more, up to saturation. Grind size, water temperature and steeping time are the parameters to set, and Costa Rica Mozart beans are used in the article to show the full process.

The French press is an immersion-style coffee brewing device with a very low barrier to entry, making it ideal for coffee lovers who have not yet mastered pour-over techniques. It filters through a metal mesh, retaining more coffee oils and delivering a fuller body than pour-over, while presenting the flavors of the coffee beans themselves to the greatest extent. This article starts from the origins and extraction principles of the French press, analyzes reasonable parameters for immersion time, water temperature, and grind size, explains the taste characteristics of French press coffee, and uses Costa Rica Mozart coffee beans as an example to fully demonstrate the French press production process and flavor performance, helping readers comprehensively understand what kinds of coffee beans are suitable for the French press and what to pay attention to when brewing.

"For coffee beginners who haven't yet learned pour-over, which brewing tool should they start with?" When encountering this kind of question, Front Street Coffee (FrontStreet Coffee) usually recommends the French press first, because it is simple to operate and convenient to use. So why exactly can the French press attract coffee lovers who have not yet mastered pour-over techniques?

French Press Coffee Extraction Principle

The French press was born in France around 1850. Its structure is not complicated, consisting of a heat-resistant glass body and a metal mesh filter with a plunger. It was originally a tool for brewing tea, but later someone tried putting coffee grounds into it and found that the resulting coffee had a rather full-bodied taste. As the pore size of the metal mesh continued to shrink, the French press gradually became widely accepted by coffee enthusiasts.

The core extraction method of the French press is immersion. Within a fixed capacity, a set amount of water evenly dissolves the flavor substances in the coffee grounds. The key variable in the extraction process is time—the longer the immersion, the more substances are dissolved, until saturation is reached, which means the longer it brews, the stronger the taste.

At this point, some people may ask Front Street: "If the French press brews for so long, won't it also extract unpleasant flavors?"

The "long time" mentioned here does not really mean brewing for ten or twenty minutes. Usually, the immersion time for a French press is controlled at 4 minutes, the water temperature is kept between 88°C and 91°C, and the coffee grind is also on the coarse side. Because the heat retention of the glass body is limited, the water temperature will continue to drop during immersion, and because the coffee particles are coarser, flavor substances are released more slowly. Four minutes is precisely the ideal immersion time for French press brewing, but it should not exceed 6 minutes at most. After immersion is finished, press down the filter and pour the coffee liquid into another container as soon as possible before drinking.

What are the characteristics of coffee brewed by French press immersion?

Compared with drip-style pour-over coffee, immersion-style French press coffee has a fuller body.

The French press relies on a metal mesh to intercept coffee grounds, and the pore size of the metal mesh is larger than that of ordinary filter paper, so most of the coffee oils can be retained during filtration. Front Street has noticed that coffee brewed with a French press has a thin layer of oil floating on the surface. The pour-over coffee we commonly see is made by pouring water through the coffee grounds and high-density filter paper. When the coffee liquid passes through the filter paper, most of the oils are intercepted, so the final cup is naturally much cleaner. Although French press coffee is fuller-bodied than pour-over, due to the design limitations of the metal mesh, quite a lot of fine coffee grounds still remain, and it is common to taste coffee grounds in the last sip.

2. Coffee brewed by French press immersion highlights the most original taste of coffee

The extraction method of the French press is similar to cupping; both belong to immersion extraction. The advantage is that it minimizes human interference and best showcases the original flavor of the beans, while the coffee taste is also more concentrated. What is human interference? For example, with pour-over coffee, you can adjust the flavor direction by changing the height and speed of pouring, or by switching to different drippers, and the coffee's performance will change accordingly. But the French press does not have these problems. The only three variables that can affect French press coffee flavor are grind size, water temperature, and immersion time.

How to use a French press to make coffee?

For this brewing, Front Street selected Costa Rica Mozart coffee beans from the Musician series. This is a coffee with dried-fruit fermentation notes, white floral aromas, and a distinct sweet-and-sour acidity. The brewing parameters are as follows:

Dose: 15 g Coffee-to-water ratio: 1:15 Grind size: medium-coarse grind (68% passing a No. 20 standard sieve) Water temperature: 90°C Immersion time: 4 minutes

First, preheat the French press with warm water, then pour the warm water out. Add the ground coffee to the French press. The grind should be slightly coarse, then pour in 225 ml of hot water (90°C). You can pour fairly vigorously (finish pouring in about 3 seconds) to let the coffee grounds tumble fully and improve extraction efficiency. After pouring is complete, pull up the filter mesh, cover with the lid, and immerse for 4 minutes. After 4 minutes, gently press down the plunger, pressing only to about one quarter of the way down the carafe to avoid fine grounds at the bottom surging upward. After pressing down, the coffee is ready to pour out and enjoy.

That's right, making coffee with a French press is just this simple. How does Mozart coffee made with a French press perform in terms of flavor?

After the coffee is poured out, Front Street smells a rich raisin fermentation note. On the palate there is a berry juice-like quality, orange blossom aroma, an obvious fermented note, and a pineapple-like sweet-and-sour taste.
