No that's not correct. You shouldn't drink coffee roasted within 7 days since there is a degassing process that takes a week. Coffee tastes good for weeks and even months if stored correctly especially for brew coffee. For espresso, 1 to 3 weeks old is ideal, but I've had great tasting shots out to 6-8 weeks depending on roast and bean origin.
A guy at my church has his own coffee business in Conroe: https://www.commissionalcoffee.com/ HEB carries Kicking Horse: https://www.kickinghorsecoffee.com/en They seem to favor strong dark coffees... we get the 454 Horsepower. I like Independence Coffee Company https://www.independencecoffee.com/ Their Jet Fuel is my favorite (a little less dark though). If you want to save a few bucks, Seattle's Best Henry's Blend is a great coffee for less than $5.
What I stated is a guideline. That said, I'd never tell somebody they can reliably get a good cup of coffee from beans that are 8 weeks old. We are in agreement that too new and too old are bad. For most folks, if they take away anything, grocery store coffee that could be 8-12 weeks old (or more) is not optimal ...which is probably 90% of the coffee consumers out there. So I think we are on the same team here. But just for fun, for you to say I'm "not correct" is a little strongly worded. It's just we differ by a few days. Also, what you find "great tasting" may vary widely so it's more of a matter of opinion, within reason.. And frankly, a great coffee can even vary wildly by so many factors including humidity, water, grinder, etc. Here is a link to one site that aligns with my perspective but, you know, internet. So I'm sure you can find something to the contrary. Is Your Coffee Too Fresh? – Clive Coffee
Weird... just saw this in Felicia Stone's twitter feed after seeing that a "Patrick Mutombo" was coaching the G-League Raptors team (no relation). Maybe it's a sign : https://mutombocoffee.com/
This stuff sounds awesome but I just can't justify paying $75/lb for coffee. https://mutombocoffee.com/the-barrel-aged-coffee-process-brew-tips/
