As I was traveling through Florida, my coffee habits mostly varied. I had a box of those pre-measured, sealed hotel coffee packets - I got them cheap on Amazon, remembering the good coffee I've had at so many hotels. Not this stuff - use a drip coffeemaker, and it's lousy and weak. The label says Arabica. The taste says Robusto...grown in the garbage dump.
BUT. Using an old percolator - I got one of the last ones made, new; it's all plastic but the base and perfect for trailer life - with that Poly-Perk machine, putting two of those packets into the brew basket, gave me decent coffee. I guess the repetitive action of washing the coffee through again and again, as a percolator does...it makes good coffee bitter; but it makes lousy coffee flavorful.
The other solution was, as you mentioned. Instant. Instant, side-by-side with good Colombian, is no contest; but when it's a cold morning, and you plug the coffeepot in while the eggs are frying...the bracing air, the scent...instant does the job. Again, use the percolator. In my world of hard water, a spoonful into a cup of water, leaves most of it at the bottom. Putting the INSTANT into the percolator basket, gets it all absorbed.
Odd solution, but that's how I am. I expect with the coffee shortage, instant will be the last to sell out, and the most convenient if I find myself economically homeless this summer.
