About 2 years ago I bought quite an amount of greens (3 sorts, 30kg each) because I was roasting for friends and family as well as for myself. The version 1 of my DIY roaster died on me and I hardly roasted for about a year whilst building version 2 and 3.
When I roast these coffees now they have a strange very in-your-face smell and taste to them, burlap like, so I reckon that they are too old / have been stored the wrong way.
I did a couple of roasts with some fresh greens to doublecheck if it's not a flaw in my roaster but they came out better than fine
So now I've got about 60kg of greens left, not suitable to roast and drink imho. Any ideas what I can do with those beans (except the obvious dumping in the bin) ?
