Grinding coffee for a French press is probably the most important step in creating a world-beating cup of coffee that is brimming with flavor.
The French press, also known as a coffee press (or cafetiere if you’re in the UK), is a beloved brewing method for its simplicity and ability to produce a full-bodied coffee.
Unlike other brewing methods that use finer ground coffee, the French press requires a coarser grind of coffee beans due to the mesh filter system.
The larger grind size ensures an optimal extraction rate while reducing the chances of fine coffee particles slipping through the mesh and causing sediment in your cup.
A quality burr grinder with a coarse setting helps achieve the right grind size, adding to the body and flavor of the coffee.
The years of trial and error when brewing French press have guided me to appreciate the importance of the coffee-to-water ratio, the freshness of the coffee beans, and the quest to find the perfect cup of coffee.
So let’s dive into some of the importance of grinding coffee for a French Press.
French Press 101 and the Best Coffee
In my experience with brewing methods, the French press is unique in its simplicity and the rich, full-bodied coffee it produces. Paying attention to the grind size of your coffee beans is crucial to mastering this technique.
What Is a French Press and How It Works
The French press consists of a cylindrical glass or stainless steel container paired with a metal or plastic plunger and a built-in (usually mesh-like) filter screen and is a beloved tool for making coffee. To brew coffee, I add coarse grounds into the press, pour hot water over them, stir briefly, and then let them steep for about four minutes before pressing down the plunger. This process separates the grounds from the liquid, leaving me with a delicious cup of French press coffee.
The Importance of Grind Size in French Press Coffee
The grind size is pivotal for a French press because it directly influences extraction. Coarser grinds are the ideal grind size for a French press as they provide the right balance of flavor extraction without passing through the filter and making the coffee gritty. A fine grind risks over-extraction and bitterness, while a grind that’s too coarse might leave you with an underwhelming, weak cup and a sour taste.
The Kind of Coffee That’s Ideal for a French Press
I prefer a darker roast for my French press because it delivers a strong, bold flavor that’s well-suited to this extraction method. Although I might add that I would always opt for specialty coffee from your local coffee roaster.
Grinding Coffee for a French Press
When making French press coffee, the grind size and quality are as important as the coffee beans I’d select. Achieving the right coarseness is crucial for the ideal extraction and flavor.
Explanation of Why You Need To Grind Coffee Beans Specifically for a French Press
When brewing with a French press, the coffee grounds steep directly in hot water, and the liquid is separated from the grounds by a metal mesh filter.
If the grind is too fine, I’ll find coffee fines, small particles, slipping through the filter and into my cup, making the coffee muddy and possibly too bitter. A coarse grind, on the other hand, ensures that the coffee is evenly extracted and the mesh can do its job properly, allowing me to enjoy a clear, full-flavored brew without the grit.
How To Grind Coffee Beans for a French Press and Set a Coffee Grinder
Before grinding the beans for my French press, I ensure my coffee grinder is clean and set to the correct coarseness level. Here’s a quick step-by-step guide:
- Selecting the Grinder: Always use a burr grinder because it provides a more consistent grind compared to a blade grinder. Burr grinders allow for precise adjustments and result in fewer fines. Additionally, they don’t blend the coffee like a blade.
- Adjusting the Grind Setting: Essentially, the grounds should resemble sea salt in texture.
- Grinding the Beans: Place the coffee beans in the grinder, set the desired level of coarseness, and grind. The goal is a uniform grind size that is roughly the same throughout.
- Measuring the Coffee: A general guideline is to use a 1:12 coffee-to-water ratio. So for every 1 gram of coffee, I use about 12 grams of water.
It is worth investing in a good manual grinder or a high-quality electric burr grinder to achieve the perfect coarse grind. By keeping these points in mind, I can consistently produce delicious French press coffee at home.
The Ideal Grind Size for a French Press
The key to making outstanding French press coffee lies in using a coarse grind size that resembles sea salt (but also not the coarsest on some grinders which may be a percolator grind). This allows for optimal extraction without the risk of over-extraction or under-extraction, creating a rich and full-bodied brew.
When preparing French press coffee, the grind size should not be fine but rather range between medium-coarse to coarse. Here’s a quick breakdown:
- Fine: Likely to slip through the press filter, leading to bitter coffee.
- Medium Grind: Can sometimes work, but often leads to inconsistent extraction.
- Medium-Coarse: Generally considered acceptable, though it can still produce some silt.
- Coarse: Ideal size, creating optimal resistance for the plunger and limiting sediment.
How to Determine the Dose of Coffee To Grind for a French Press
In my experience, nailing the right amount of coffee to grind for a French Press is essential for a perfect brew. I’ll be walking you through this straightforward process, emphasizing precise measurements for different capacities to address every coffee lover’s needs.
Guidelines for How Much Coffee To Grind for a French Press
To start, I always stick to the recommended coffee-to-water ratio of 1:12 to 1:16, which translates to about 1 gram of coffee for every 12 to 16 grams of water. Let’s break down what this looks like for different French press sizes:
- 8 Cup French Press: For this common size, which corresponds to 34 oz, I find that using 60-70 grams of coarse coffee grounds achieves a bold and rich flavor.
- 16 Oz French Press: Half the size of the 8-cup, so I use around 30-35 grams of coffee.
- 32 Oz French Press: This one’s double the size of the 16 oz, necessitating 65-70 grams of coffee to maintain the balance.
- 1 Cup French Press: Typically, a single cup is 4 oz, so I’d opt for approximately 8-9 grams of coffee.
In each case, ensure the grind size is coarse, resembling sea salt, to prevent over-extraction and bitterness. The Baratza Encore is my go-to grinder, set around 28 to 32 for the perfect coarse coffee grounds.
As for brew time, I let my grounds steep for about 4 minutes, which I find to be the sweet spot for full flavor extraction without bitterness. Maintaining a water temperature of about 195°F to 205°F is also crucial because too hot water can cause over-extraction, while too cool may under-extract, leading to a weaker brew.
Remember, all these suggestions may vary slightly per your taste preference, but they offer a solid foundation for your French press coffee adventures.
The Best Coffee Beans for Your French Press
When I think about making the perfect cup of coffee in a French Press, the choice of coffee beans is paramount. Not only does it influence the flavor and oils that are extracted during the brewing process, but it also affects the bloom and overall freshness of the coffee.
In my experience, dark roast coffee beans are usually the most suitable for a French Press. The reason is quite simple: a French Press does a great job at allowing the rich, bold flavors and oils of dark roasted beans to shine through. The natural oils released during the brew contribute to a full-bodied and complex cup of coffee.
Here’s a quick breakdown of the types of beans I find work best:
- Single-origin beans: These offer unique characteristics from their specific region which can make your morning cup a true adventure in taste.
- Blend of beans: A blend can balance different flavors and ensure a rich, harmonious cup.
When selecting coffee beans for your French Press, freshness and specialty are key to achieving that perfect cup.
I always order coffee online or pick up a bag from a nearby coffee roaster and grind the coffee beans right before brewing, as this will also maximize the bloom while preserving the coveted flavors and aromas.
Whole Beans or Ground Coffee in a French Press?
Now, I can’t emphasize this enough: grinding your own whole-bean coffee just before brewing makes a world of difference! It allows me to control the grind size, which is crucial for a French Press. Aim for a coarse grind to prevent over-extraction and to ensure the final cup isn’t filled with sediment, which isn’t pleasant.
- Whole bean coffee: Buy it fresh and grind just before brewing.
- Pre-ground coffee: If it’s your only option, make sure it’s a coarse grind meant for French Press and as fresh as possible.
Brewing with a French Press using ground coffee that’s too fine can result in a bitter cup, as fine grounds extract faster and can over-extract if they stay in contact with water too long. So if you’re purchasing pre-ground coffee, make sure the label specifies it’s suitable for French Press, or you might end up with a subpar experience.
