We try our best to offer very special, even rare coffees that we can only get once in a while. If these coffees do not carry a certification, we are carrying the coffee because it is still sustainably grown, the farms are using environmentally sound farming methods, and/or they are socially responsible, either the farmer is getting more money for his/her crop than they would get via normal trade or the money from the sale of that coffee is going towards a social program in the country of origin.
