Blade vs. Burr: Why Your Grinder Matters, Too

When most people think about great coffee, they think about the beans, where they’re grown, how they’re roasted, and the tasting notes. And while the beans are definitely the star of the show, there’s another player that can make or break your cup: your grinder.

Whether you’re brewing at home with a French press, dialing in shots on an espresso machine, or just looking to up your daily coffee game, the grinder you choose shapes your coffee’s flavor more than you might realize.

Blade Grinders: The Jack-of-All-Trades

Blade grinders look a lot like little food processors, and they work about the same way. A spinning blade chops up the beans into smaller pieces. They’re affordable, easy to find, and simple to use.

The catch? They don’t produce uniform coffee grounds. You’ll end up with some pieces the size of boulders and others that are almost dust. This uneven grind can cause over-extraction (bitter flavors) and under-extraction (sour, weak flavors) all in the same cup.

Pros: Inexpensive, compact, and portable, and works in a pinch.

Cons: Uneven grind size, less control over flavor, and can create heat that affects taste.

Burr Grinders: The Game Changer

Burr grinders use two abrasive surfaces (the “burrs”) to crush beans to a consistent size. The beans are guided through at a set distance, which means you get grounds that are uniform every single time. That consistency is what allows you to actually taste what the roaster intended: balanced sweetness, rich body, and clear flavor notes.

Burr grinders come in two main types:

Flat burrs are often found in commercial grinders, known for precision.

Conical burrs are quieter, more energy-efficient, and still extremely consistent.

Pros: Repeatable and even grind size, better flavor clarity, and adjustable settings for any brew method.

Cons: Pricier than blade grinders, usually larger and heavier.

Why It Matters?

Grind size is the link between the coffee you have and the coffee you taste. If your grind is too coarse, water runs through too fast, leaving your coffee under-extracted and weak. Too fine, and it’s over-extracted and bitter.

A good burr grinder gives you control over that grind size so you can match it to your brewing method, whether that’s an espresso machine, a French press, or a pour-over.

Think of it like photography: you can have the best camera in the world (your beans), but if your lens (the grinder) isn’t right, your shot won’t turn out the way you envisioned.

Our Recommendation

If you’re just starting your at-home coffee journey, a burr grinder is one of the best investments you can make. It doesn’t have to be the most expensive model on the market; there are excellent entry-level burr grinders that will instantly upgrade your cup.

Some of our favorites:

• Fellow Ode Gen 2 (great for pour-overs & drip coffee)

• Baratza Encore (all-around workhorse)

• 1Zpresso JX (manual option for travelers or small spaces)

The Bottom Line

Coffee is a sum of its parts: beans, water, brew method, and yes, the grinder. If you want to taste the full potential of your coffee, a burr grinder is the way to go.

After all, your coffee deserves better than a game of “Will this sip be bitter or sour?”
