This is quite exciting in that it removes plastic waste. I see no reason why different companies can’t make different shape ones to maintain their lock-in. I expect a knock-off market to pop-up, but that exists with plastic pods too. It’s a step in the right direction at least.
All coffee pods are garbage.
Especially espresso pods. There’s a place around here that has a 20,000 dollar espresso machine, that serves over-extracted espresso because the owner felt pods were easier or something.
