Why Grind Size Matters?

When it comes to making the perfect cup of drip coffee, grind size matters a lot. It’s one of the most overlooked aspects of home brewing, yet it can completely make or break your morning cup. So, what’s the best grind size for drip coffee? Let’s find out.

The Ideal Grind: Medium

For standard drip coffee makers—whether they’re automatic machines or manual pour-over brewers—amedium grind is the sweet spot. Think of the texture of granulated sugar: not too coarse, not too fine. This grind allows for optimal extraction time, where the water stays in contact with the coffee just long enough to absorb the flavors without over-extracting bitter compounds.

Extraction and Flavor Balance

It all comes down to surface area and extraction rate. A finer grind has more surface area, which can lead to over-extraction—making your coffee taste bitter or harsh. A grind that's too coarse, on the other hand, leads to under-extraction, resulting in a weak, sour, or watery brew.

Why Medium Works Best?

Medium grind works best because it balances these two extremes. It's coarse enough to prevent over-extraction but fine enough to ensure the water doesn’t just rush through the grounds. This makes it ideal for most flat-bottom or cone-shaped drip coffee machines.

Adjusting To Your Taste

Ultimately, the “perfect” grind can vary slightly depending on your machine, coffee beans, and taste preference. Start with a medium grind and adjust based on taste: too bitter? Go coarser. Too sour or weak? Go finer.

Pro tip:Invest in a burr grinder instead of a blade grinder for consistent particle size—consistency is key for even extraction and flavor. A great option for home brewers is theMelitta Molino burr grinder, which offers adjustable settings and delivers a uniform grind that’s perfect for drip brewing.

Great coffee isn’t just about the beans or the machine—it’s also about how you grind. Master your grind, and you’re well on your way to barista-level drip coffee at home.
