I disagree, I’ve found a very significant difference between pre-ground and freshly ground coffee.

There are volatile organic compounds in coffee that begin to dissipate and react with oxygen as soon as they are exposed to the air by being ground.

I’m no coffee snob, I’m not advocating a high end burr grinder, the cheapest one on Amazon will do (~$60).

Same with the brewing method. Aeropress is great too, but anyone can find Meltia pour over filter holders and filters for $5 at their grocery store.
