Beans staling fast - why?
I'm living abroad and wanted to get any opinions on this problem I have.
Bought roasted beans from a local roaster, typically bought about 3-4 days post roast, are staling fast. Really fast. They are stored correctly, in the usual one way valve disposable coffee bag, in a cool and dry location. They taste great to begin with, blooming up nicely in the dripper and still giving off a bit of C02, but then, maybe 1 week and some change after purchase, it happens. I grind them up and brew, and the cup has these lingering stale notes. You know the stale taste I mean, we've all had instant coffee at one point in our lives, so this stale bitter/grainy taste is seared into our brains. Your contempt for this stale taste is what led you to this forum. So carrying on, bad brewing technique perhaps, maybe a scorched bean snuck in there, try again the next day, same thing. And again, repeat. Beans from this vendor are staling quickly.
To rule out error on my behalf I have never had a problem in Sydney with this phenomenon.
Does anyone have any theories why beans would prematurely, after say a week, taste stale?
Thanks to anyone who contributes.
My 1st reaction based on the fact you say are doing all the right things, is that your vendor is NOT doing all the right things. I assume you checked the packaging has a Roast Date and not a Use By or Best By date? So they may not be being as truthful as you would expect, or they are mixing old & new stock so it's a half truth. I would try another vendor.
I'm sure there are other considerations such as environmental (i.e. different to Sydney climate & conditions), type of bean and roasting method, but I would still expect 3-4 weeks before it starts staling.
Try another roaster/bean if possible.
