..used to always contain a blend of Robusta beans. And in many Espresso bars in Italy, Robusta blend is still used. However most modern cafes, including McDonalds, will now only serve 100% Arabica :(
To quote an Italian coffee roaster, Yor Balini, who's family has been roasting for decades.
" the blend for espresso is supposed to be 70% robusta / 30% Arabica
,we don’t drink robusta because is cheaper. We roast coffee from centuries now and this blend ends up being the best for the traditional espresso style"
FOB Coffee Espresso blend follows the traditional Italian ratio ,and uses the highest quality Robusta beans from Di Linh Vietnam
