Due to... reasons... I have many pounds of unroasted, green coffee, some of it has been vac sealed and some has been subject to poor storage. Range 5-7 years.
I roasted samples of some and results were pretty nasty.
Safe to compost? Will the inherent caffeine get into the soil and then into my tomatoes? Chuck them in the trash bin?
If the caffeine absorbs into the tomatoes, then, like the tomacco, I can have caffatos.
Searching interwebs seems to only yield results for roasted grounds. That's an easy one.
