Thank you for your interesting post. I always try to buy roasted Arabica beans, because I know it is the best coffee. However, in our supermarkets it is sometimes difficult to choose a quality coffee, as not all producers write the type of coffee on their packaging. Sometimes they write the Arabica to Robusta ratio or just 100% Arabica, but sometimes they don't write anything at all,which is very surprising and does not inspire confidence.
