Why You Shouldn't Buy Coarsely Ground Coffee For French Press

If you walk down the coffee aisle of a high-end grocery store, you might see bags specifically labeled "French Press Grind" or "Coarse Grind." It feels like a convenient hack. You get the right grind size without doing the work, right?

While buying coarsely ground coffee for French press might save you thirty seconds in the morning, it is costing you almost all of the flavor in your cup. Here is why you should leave those bags on the shelf.

The Science of Staling

Coffee beans are like natural vaults. They protect the delicate oils and aromatics inside from their worst enemy: Oxygen. Once you break a bean apart, you increase its surface area exponentially.

Even though a coarse grind has less surface area than a fine espresso grind, it is still exposed. Within 15 to 30 minutes of grinding, coffee loses about 60% of its aroma. If that bag was ground a week ago in a factory, you are essentially buying stale coffee. It might taste "strong," but it will lack the sweetness, fruit, and chocolate notes that make French Press coffee great.

The "Sludge" Problem

So, you decide to grind at home. Great! But if you use a cheap blade grinder (the ones that look like mini blenders), you are trading one problem for another. Blade grinders don't "grind" beans; they chop them. This creates a mix of huge boulders and tiny dust particles.

In a French Press, those tiny dust particles (fines) slip right through the metal mesh filter. The result? A muddy, gritty cup of coffee with a layer of silt at the bottom that ruins the last sip.

The Solution: Precision Grinding

To get a clean, sweet cup of French Press, you need a burr grinder that produces uniform particles. You want chunks that look like Kosher sea salt, with zero dust.

I use the Fellow Ode Gen 2. It is designed specifically for brew methods like French Press and Pour Over. The 64mm flat burrs create a grind so consistent that the coffee comes out clean and tea-like, with all the heavy body you want but none of the grit.

The Final Cup

The French Press is a method that rewards patience, but it punishes shortcuts. Don't buy pre-ground. Buy whole beans and grind them right before you brew.

And since you are now grinding fresh, you need fresh beans. I get my single-origin roasts from Trade Coffee to ensure that the beans in my hopper are always at their peak.
