Vacations bring some odd coffee experiences; for me this one had me drinking Nespresso and Keurig pod coffees.
For both systems, I went through several different coffees, and came to the same conclusions. Aromatic coffees in light to medium roasts, when done in pods, lack the acidity, aroma and sweetness of fresh coffees; the pod versions are obviously stale. However, medium and darker roasts, especially of non-acidic or relatively unaromatic coffees are frequently better and almost always as good as the fresh ground and regularly made version. So what gives?
The pod systems do a technically correct extraction; as good or better than most people can do for themselves, and very close to best practice. So if the roast does not deteriorate in the packaging, the system will produce at a high standard. Apparently, this packaging technology is good enough to preserve the darker roast flavors and aromatics, but not the lighter roast ones. So the pod systems do a good job with darker roast arabicas and robustas, but not with light roasted arabicas.
Three conclusions: First, if you have to use pods, select darker roasts. Second, these technologies will hit Starbucks far harder than Dunkin Donuts, and dark roasting businesses more than light roasting ones. Third, because of this bias in the way pods stale, this technology may actually lead to improved specialty coffee.
