What kind of grinder are you using?  Since it is french press, it should be quick to grind (since it is so coarse).  Is the time-consuming part just the routine of getting the grinder out, filling it, etc.?

I use a Black and Decker grinder. Yes, it's just the routine. Although it doesn't take very long, it's still annoying to have to get out the grinder every morning when I'm already pressed for time.

# What's best median between grinding coffee beans every day or the whole bag at once so that it stays relatively fresh?

(Asked by: username_0 on 2023-10-13)

I recently switched from buying pre-ground coffee to whole beans and I am grinding it myself at home for a French Press.

I know that grinding coffee every time I want to make it would be the freshest way to enjoy it. However, this is time-consuming to do every morning. I typically only drink one cup per day so if I grind the whole bag at once I am afraid it would get stale.

What would be the best median between grinding it every day or the whole bag at once so that the ground coffee still remains relatively fresh?

According to a [previous question/answer here](https://coffee.stackexchange.com/questions/123/when-does-coffee-go-off/166#166), even whole bean coffee may be appreciably stale after 14 days, and ground coffee within minutes. If you are considering pre-grinding, any number of days is probably going to affect flavor. Why not experiment? I don't think you will want to wait 14 days with ground, but you could experiment and see if you can taste a difference after 7 days.

You mention using a Black and Decker grinder. If that's a typical blade grinder and not one of their burr grinders, you might find that having your beans ground with a coarse setting at the coffee shop tastes better even at 14 days with a French Press.

What kind of grinder and how much coffee are you using? Even with my (slow) hand grinder, I don't need more than 30-40 seconds to grind my coffee. Are you brewing a lot of coffee at once?

For you, this "cupping" method has the added benefit of having the coffee taste fairly similar to the way it would in a french press.
