I can get small batches of green decaf beans at my local roastery, I'll give it a go and report back.
Tho' I've just received a variety pack of decafs from a new roaster, started with the medium/dark today and it's pretty good. It'll take me a while to get through that lot.
If you've already got one, there's no harm in giving it a go! Think Redber sell green beans in as little as 250g bags.
