What they're capturing here is that instant coffee can capture the ideal roast-to-brew timing, then dry it out. Drip coffee has so many factors - when the beans were roasted and ground, what type of grinder was used (burr is usually best), water temperature (200F/93C for brewing, give or take), how long it was sitting on a burner after being brewed, etc. Whole beans are usually best within 3 weeks of roasting, ground beans about 3 days from breaking a flavor seal (vacuum packing helps). Try drip coffee like that vs, say, Folger's Crystals a week after opening the can. There should be no natural sourness to it, and when my mom brews ground, canned coffee, it tastes like someone added a lemon.
