received as a gift, I rinsed the tank. then I put water in the tank, the T-disc set, put a bowl, pressing start doing it 4 times. on first use, I did not know how much I put a large cup. I put a disc "espresso" and saw that it was the right dose. then I realized that the amount was determined by the barcode. the taste is good. the discs are expensive. this machine is profitable for chocolate. there are recipes on the site tassimo.
