Is a conical or flat burr coffee grinder better?

QUESTION:

Hi:

I'm looking to purchase a new grinder. The one I have now is NOISY, and does create more powder than I want. I really want no powder when I grind for the French pot.

I see grinders come in flat and conical. What's the difference and which is best?

Which of the flat or conical is less noisy?

Thanks,

Ralph


ANSWER:

Ralph, hi

If you are getting a lot of powder, I’m guessing you are using a blade grinder right now. The upgrade to a burr grinder is a great idea. You’ll get a much more even and consistent grind.

When it comes to choosing between flat plates and conical plates, the conical grinders win my vote for a couple of reasons.

First, they are a little less noisy, which I think you will appreciate.

Second, the speed at which the plate rotates is usually slower than with a flat plate grinder. This means, in addition to less noise, you also get less friction and heat being produced. And this reduces loss of flavor through the coffee’s oils being vaporized.
