I’m a coffee fanatic. Love the stuff. I go through a pound of espresso beans every ten days or so. I’m also an entrepreneur, and as such, I see annoying problems for what they really are: opportunities. I’d like to see somebody design a better coffee bag that satisfies the needs of the coffee shop, while also preserving the freshness of my beans for an extended period.
The 1lb coffee bag makes no sense. The quality of the coffee bean degrades significantly after a bag is opened. If you grind your coffee at the store or buy it pre-ground, that’s even worse. You lose all the key oils shortly after grinding coffee and exposing it to air. So you don’t realize it, but you don’t even know what coffee tastes like when it’s not stale. All your coffee is stale.
But even for fanatics like me who buy whole beans and grind only the amount they are going to use right then, we still lose a significant amount of quality after that bag is opened. There’s a whole lot of science behind this, but it’s obvious in the taste and quality of espresso shots I pull on my home machine. The day I buy a new bag of coffee, it’s amazing. It’s noticeably different. And that quality steadily degrades over the next few days, and finally hits a bottom around 5 days out. The last half of each bag is noticeably worse than the first half.
There’s probably some arbitrary reason that coffee was first bagged in 1 lb bags, but why is it still bagged that way today? Mostly it’s because the coffee shops have no incentive to decrease bag size when the consumer is already conditioned to buy a 1 lb bag, whether they need it or not. I’ve seen some shops experiment with half-pound bags, but that kills their bottom line. They need to sell you a 1 lb bag and they don’t want to stop. There are also some high end shops that sell 12 oz bags (3/4 lb), but that’s not an attempt to solve this problem. They do this because those high quality beans cost so much that they need to decrease the weight to keep it within the consumer’s perceived price point for a bag of coffee.
So that’s where it stands today. I pay $15/lb of espresso beans and my coffee degrades in quality every day after I open it. By the time I get to the last couple days of a bag, I can’t wait to go buy a new one and get a day or two of top quality again. There’s got to be a better way.
Here’s my solution. We need to keep the 1lb bag because the businesses don’t want to sell less volume and hurt their sales. The coffee beans stay good until the air seal is broken. So, why not make a one pound bag that has three or four compartments? Each would open from a small strip that could be pulled back, and would open only the individual compartment. The challenge would be designing a bag like this that does not significantly increase the complexity of packing the bag for the roaster. If we can solve this problem, then both me and the growing consumer base in the high end coffee industry would be very happy.
I have no physical engineering skills, so if anybody wants to team up and prototype this thing for fun, let me know. Consider it a challenge.
