So.. I am a k-cup hater. I absolutely hate the machines. They make shit coffee that you can only get in one good size. Want a large coffee? Too bad we're a tiny cup so it's going to be weak, you can make normal coffee (normal crappy instant) and you can make over strong coffee. There is also the issue that the temperature of the machine is several degrees lower than what is the gold standard by just about 5 degrees. Then there is the issue that the cups aren't recyclable.
I really don't understand it. I also don't understand the keurig tea?!!! Tea?!!! People are so damn lazy they can't dump a tea bag in a cup anymore they have to stick it in a machine?! I personally find scooping with an infuser with some leaves to be faster than a bag and less hassle as the water just drips right out and with a little vigor it's quite easy to shake most of the water out. Quick rinse and done.
I also am confused by the hot chocolate ones. It's too much to just scoop hot chocolate and add water? Or tear open a package? It just seems incredibly lazy.
There are a couple problems I have.
Non-recyclable.
Makes average to crappy coffee
Average coffee that cost the same amount as better beans.
It is advertised as a premium object but it's fucking glorified instant coffee.
There are plenty of other options you can use if you want a single cup, like an aero-press or a french press.
And yes I know there are the reusable cups but they're not main-stream they're not in abundance of use so there is still the issue of billions of cups about.
