When you say "the beans we get here", do you mean within Australia or this web site?
If you mean this web site, then we are talking green unroasted beans on offer. You will have to roast them as they have never been roasted before.
If you mean roasted beans on offer from other people, then re-roasting Im sure is possible, but seems to be an attempt to justify selling/buying/using beans that are past their best.
If youre happy to do some roasting, buy your beans green and join our group of obsessed coffee nerds!!
