What Grind Size Is the French Press Grind?

Coffee grinds range from fine to coarse with various levels in between. The grind level you choose all depends on the coffee preparation method you are using.

Fine grinds are a bit smooth and powdery, while coarse grinds feature larger particles, similar to those of sea salt. With a French press, the rule is this simple: the more coarse your grounds are, the better the coffee.

If you’ve bought coffee beans for French Press, make sure you a quality burr grinder to prep your coffee for brewing. Study the various settings to understand which one to use for your French press. Be careful not to end up with grounds that are too coarse because water will quickly rush through them and fail to pick up all those sweet and bold flavors we all cherish.

Take your time to also fully understand the various coarse grind levels your burr grinder can yield. Keep this in mind: the more coarse your grind is, the longer the extraction time. Let’s look at each of them briefly.

Coarse Grounds

Coarse grounds have the same size and shape as chunky sea salt. This ground level is perfect for French presses and will only take around four minutes to brew.

Medium-Coarse Grounds

These grounds have roughly the same consistency as grains of sand and only take about two minutes to brew. They are primarily used in specialty devices such as Chemex brewers and when making cafe solo.

Extra Coarse Grinds

Extra coarse grounds resemble peppercorns in size and shape. On most burr grinders, this is the farthest you can go when it comes to coarse grind levels.  Because the extraction time is longer (up to 12 hours), such a grind is best for cold brews or French press iced coffee.

Additionally, never forget that extraction time matters a lot. Under-extracted French press coffee tends to be sour, salty, and acidic, while over-extracted coffee will only be bitter without any of the usual cherished coffee flavors.

So, what’s the science behind using coarse grinds for a French press? Let’s find out.

Why Coarse Is the Perfect French Press Coffee Grind Level

Earlier on, I mentioned that coarsely ground coffee beans yield the most delicious French press coffee. Well, it’s true, and here’s how and why that happens.

By now, you are familiar with the extraction stage in the coffee-making process. For starters, this is when water passes through your ground coffee beans, drawing out your desired flavors. Now, a lot can happen during this moment that determines the kind of coffee you end up with.

For example, a French press uses minimal pressure to pass the water through the coarsely ground coffee. You could use a fine grind, but this will only lead to over-extraction. There’s also the possibility of the grinds getting stuck in the mesh of your French Press coffee maker or finding their way into your cup, which nobody wants.

However, if you use such grounds in an espresso machine, the outcome will be perfect because it extracts in just 20 to 30 seconds.

Now, back to a coarse grind and why it’s so necessary for French press brewing. First of all, it gives your French Press enough time to extract more flavor from the beans. Another reason for using such grounds is so the plunger encounters a bit of resistance when you press it down.

Buying Coarse-Ground Coffee

Of course, a burr grinder makes coffee-making easier. All you have to do is dial in a setting, depending on your brew method, and the grinder does the rest. But should you be worried if you lack one? Absolutely not!

You always have another option, which is to buy ground coffee for your French press, or have your beans ground to the right size at the place where you buy them. This, however comes with a downside.

 

First, not all coarsely ground coffee beans you see in online stores and coffee shops are perfect for your French press. You have to do a bit of research and leg work to land on the best option for you and your press.

Freshness is top on the list of things you have to pay extra attention to. Look at the packaging date, and always go for the most recent bag you can find. Coffee that is older than four weeks has most likely lost some of its complex flavors.

Other factors to watch out for include:

What is stronger: coarse or finely ground coffee?

The strength of your coffee depends on so many factors, from the type, quality, and origin of your coffee beans to the roast level. Now, these factors will be outside your control once you have purchased your coffee beans, but one thing remains that determines how strong or weak your coffee could be: grind size.

As the extraction takes place, caffeine is produced from the beans. The use of hot water at a higher pressure creates the perfect environment for maximum extraction of caffeine and flavor from the grounds. That is why finely ground coffee will release more caffeine, leading to stronger coffee compared to coarsely ground coffee.
