Both jars do the job; the one on the right is less pretty but more effective because it protects the content against the light. I like keeping coffee in small portions, too, but when we're expecting guests, I ground what we will use during the day as soon as I wake up, just in case we have a power outage.

Hi, Marlyn! It's true.

I guarantee that your coffee is freshly ground. Fortunately, I have had the pleasure of tasting your delicious preparations.
Hugs!
