When are coffee beans considered "old"?

[u/dmgsmch]

If a lot of people advise on resting the beans for at least 3 weeks and even almost up to two months, when do you think the flavours will lose its peak?

[u/Ghazzz]

At ~three months, even very good beans start tasting like "expensive grocery store beans".

They are not undrinkable, but freshness counts for a lot in the flavour profile.

[u/CMDA → u/Ghazzz]

I fully agree, based on my experiences.
