Yes my search for decent coffee beans still continues after years of testing. To be honest I've given up hope. Even expensive beans bought from Cafe Martinez tasted very weak. At the moment I use Casa Do Cafe off of the guy who comes every Monday from BA to deliver then to all the cafes in the town....it's the best yet although nowhere near as good as a average variety bought in a UK supermarket.
I think I need to buy a espresso machine and milk frother to get the best out of the beans as the same coffee tastes better when had in a cafe.
