technically, how can they make ground coffee in a pod comparable to freshly ground coffee? even if you use an inert gas in the pod, aren't you going to have chemical changes in the pod? and some loss (evaporation) of lighter chemicals? it seems like if grinding freshly is important (and i have heard many times that it is), then it's just not physically possible to reproduce the taste via a pre-ground pod. odd.
- dreamfactory 13y agoThe gas works well at preserving the coffee from oxidation. The bigger problem is with water temperature - espresso is incredibly sensitive and will become either sour or bitter if the temperature goes outside a very narrow band. This is what you are spending money on with expensive espresso machines - PID temperature controls and lots of heavy brass parts to maintain an even heat. Nespresso machines are pretty cheap and plastic and I believe they use specially made bland coffee blends to disguise this. Frankly you are better off with French press or pourover at home.
