They all go stale after few hours if I can recall so no matter how airtight the seal is the beans are already stale to some extend. I try to buy 1kg at any one time …
However, ground will go stale even quicker.
I have tried “freshly roasted” local coffee beans and those I bought from TK Maxx roasted by some Merican roasters, all I can say is I find the ones from Merica much better if not the best. It is the origin of the bean that makes the different. Good beans good taste … shite beans, no matter how freshly roasted, will taste shite.
beans are not ‘already stale’ they need to de-gas post roast and are best left for about 5 days then they have an optimum window of about 3 weeks before they start to change for the worse.
‘good beans good taste’ i don’t agree. it’s not difficult to ruin beans with poor roast profiling. coffee is seasonal and there are only a handful of bulk shippers int he U.K. so you can often find the same single origin beans available from different roasters. having cupped/tasted the same beans from different roasters i was surprised how different they could be, and how poor some roasters were.
any beans in TKmax are probably well past their best even if they were any good when fresh, i wouldn’t buy them for a cat litter tray let alone to drink.
