Fresh is best.
The same goes for coffee.
Many customers ask myself included, "what is the best way to store coffee beans?"
Expired coffee beans won't make you sick, but the flavor and taste will be off.
How long does coffee last once opened?
Most coffee professionals suggest that once a bag of coffee is open, you have a week to consume it. I disagree. I'll drink it until the coffee smell changes. For me, its when it stops smelling fresh.
Furthermore, when I buy a bag of coffee, I'll buy it whole beans and grind it myself. Its' one way I extend the freshness.
In my family, a three-pound bag of SF Bay Coffee lasts about three weeks. And it last that long because I work for a coffee roaster and there is an endless supply of coffee, therefore, I drink my cups of coffee at work. Thanks, Rogers Family! So for the normal family, I'd suggest a pound of coffee per person, per week. But coffee consumption is subjective.
Exposure to Light
Once more, you should store your coffee in an airtight container away from the light. Now, if you're only one cup a day person, I'd suggest storing your OneCups or coffee beans in an airtight and light proof container. I have used both mason jars and airtight coffee containers and just simply store the container in a cabinet.
Whatever you do, please do not freeze coffee. Why? Small ice crystals form and will change the taste of coffee. The freezer is great to store many things, but coffee is not one of them.
And for those of you who wonder why we use a mesh filter instead of plastic, the answer is that we believe you get a fresher, better tasting cup of coffee. And if you've tried it, you probably agree.
