I ordered the green coffee, to let off a bit to roast themselves (in a frying pan). It was fun to watch as slowly changes the color of the coffee beans. Tasted the coffee, although very feeble, but that has less situated on the beans, than on the fact that I have no idea of roasting!
Conclusion: Anyone who wants to just try something new and offer guests a coffee "private label", this opportunity should not be missed!
