I never tasted an Australian grown Achacha , but the fruit in the pic I posted with the Mex. is the variety that is grown in Australia . The same variety of achachairu is also growing and fruiting in Guatemala and at Raul's and my place .
I had conversations with one of the Bolivian guys involved in this Australian deal , this was mentioned several times in this forum if my memory is right . In Bolivia this type of fruit is commonly called achachairu , just like we would say a mango , they do differentiate them by adding : small , sweet , sour , big , huge to the word Achachairu ....
