French Press for Dark Roast Coffee Beans: Flavor Characteristics and Brewing Techniques

The Art of French Press Coffee

Among urban coffee enthusiasts, some appreciate the ritualistic elegance of pour-over coffee, while others are drawn to the laboratory-like precision of siphon brewing. Then there are those who prefer the simplicity and convenience of the French press. Yet the magic of each coffee brewing device extends far beyond its appearance and operation. Making coffee is more like a science—each device has its unique way of extracting coffee's essence, requiring us to continuously experiment with combinations to find the perfect ratio and optimal flavor profile.

The design principle of the French press is remarkably simple: just pour water and coffee grounds into the container, then use the plunger to push the coffee grounds to the bottom, completing the filtration process. The metal filter can be cleaned and reused. Despite its simplicity, it's incredibly efficient and doesn't require paper filters, making it more environmentally friendly and cost-effective. The French press is one of the quickest ways to extract coffee's authentic flavor, preserving precious natural oils that would otherwise be absorbed by paper filters, thus presenting coffee's most original, rich, and complex flavor characteristics.

Operating a French press is as simple as a "lazy person's coffee device"—convenient yet without compromising the complete flavor profile of a good cup of coffee.

In fact, French press extraction is the brewing method closest to cupping, bringing out the full spectrum of coffee's oils, aromas, and flavors. With its smooth, sweet, and rich mouthfeel, it's an excellent choice for breakfast coffee.

Choosing the Right Beans for French Press

For French press brewing, single-origin coffee beans or those with prominent fruit acidity work best, particularly medium to dark roasted beans. FrontStreet Coffee recommends using beans with good balance. For example, in FrontStreet Coffee's bean selection, daily drinkers like Brazilian coffee beans, Colombian Huilan coffee beans, Indonesian Mandheling coffee beans, and Costa Rica Tarrazu coffee beans are all excellent choices. FrontStreet Coffee mentions that these particular beans offer balanced flavors with notes of dark chocolate and fruit. Because the French press uses immersion extraction, it can express coffee's oils, aromas, and rich coffee character effectively, while dark-roasted beans tend to showcase coffee's aroma and body better. Therefore, FrontStreet Coffee's medium to dark roasted beans are particularly suitable for French press brewing. Coffee made with a French press from dark-roasted beans offers better aroma and a richer mouthfeel.

As for light-roasted coffee beans, FrontStreet Coffee does not recommend using them in a French press. Ethiopian coffee beans are generally more suitable for light roasting. For instance, FrontStreet Coffee's Yirgacheffe Red Cherry coffee—when brewed with pour-over—easily highlights lemon, floral, and fruity flavor notes. However, when using French press immersion, the resulting flavor profile tends to be relatively singular and muted.

French Press Brewing Guide

Let's see how FrontStreet Coffee makes an excellent cup of French press coffee. FrontStreet Coffee's Brazil Queen, Mandheling, and Colombian Huilan all have flavor profiles suitable for French press. Let's demonstrate using this Colombian Huilan coffee bean.

FrontStreet Coffee's house-roasted coffee beans should be ground to a French press-suitable grind size using properly rested Huilan beans. Medium-coarse grind is ideal—coarser than pour-over coffee grounds. FrontStreet Coffee recommends using a standard sieve with 70-75% pass-through rate. If the powder is too fine, coffee grounds will escape through the filter mesh holes, making the coffee cloudy.

You can start with a 1:10 coffee-to-water ratio. For a 2-cup serving, that would be 20g of coffee beans with approximately 200g of water. The final ratio depends on your taste preference. FrontStreet Coffee's drip coffee bags contain 10g each. Using pre-ground drip bag coffee like seasonal Brazilian and Mandheling drip bags for French press is particularly convenient. FrontStreet Coffee recommends a 1:16 ratio—15g of coffee grounds with 240g of water.

FrontStreet Coffee recommends preparing an electronic scale. Even if your French press has measurement markings and a scoop, using a scale is still advised because coffee bean density changes due to various factors including growing altitude and roasting method. Each bean variety has different mass and weight. Additionally, if you make an exceptionally delicious coffee and want to replicate that flavor, you must record the ratio. Conversely, if you make a poor cup of coffee, the data will help you know how to adjust.

At FrontStreet Coffee, fresh, clean Yibao mineral soft water is used. Avoid using very hard water for extraction, and don't use unfiltered water. If the water quality is poor, it's difficult to make good coffee.

FrontStreet Coffee's Brewing Steps:

1. Grind the coffee beans and pour them into the French press. At this point, ignore what many people say about grind size—don't grind too coarse, medium grind is sufficient.

2. Bring water to a boil. Water temperature should be 93°C, then pour in the appropriate amount of water. We used 15g of coffee grounds with 240g of hot water. Stir with a spoon to ensure the coffee grounds and water are fully mixed.

3. Place the lid on the French press with the filter at the highest position, then let it steep for 4 minutes.

4. Before pressing the filter, you can open the lid and use a spoon to skim off the foam and small fragments floating on top, then press the filter all the way down.

5. Brewing complete! Immediately pour the coffee into another thermal container! Don't delay, as the coffee grounds are still steeping inside. Then pour into cups and enjoy slowly.

Conclusion

The French press is the simplest, most convenient, and environmentally friendly brewing method. The coffee it produces is stronger, more flavorful, and has more complexity than fully automatic drip coffee machines. Plus, it requires no electricity, no heating, no paper filters, is easy to clean, and allows you to consume the coffee oils along with the brew. It's perfect for busy professionals who want to steal a moment of leisure. Go ahead and try making it yourself!
