Tbh I honestly can't tell any difference. My work has a Nespresso machine and it doesn't taste different from whatever instant I pick up at the supermarket. Whenever I get coffee out it's the same. "ooooh you must try this new artisan coffee shop" ok, it tastes like coffee, I might get some milk art and a nice atmosphere but that's it? I think loads of these things you can only taste the difference when you're so into it and super attuned. Same goes for wine, gin etc.
