Thats one hell of a Corretto! :)
Theres at least one major coffee roaster in Sydney where you can do the same thing, though on a smaller scale, using a 600gm Green Bean Machine. I think they might actually lose money on the scheme but its a nice to have for the patrons.
While I was there I looked at their retail packs and it was sad to see there was at least a 3 month best before date on the packs instead of a roast date. Also printed on the pack was advice that once opened, the beans should be kept in either the fridge or freezer. :o
