The RFID chip contains a unique serial number for the coffee you're about to prepare. This serial number is associated with a range of information in our Coffee Cloud, including the ideal roasting curve for the bean. When you scan the RFID chip, it sends this number to the Coffee Cloud, which then tells the machine what temperature to use at various stages of the roasting process.
It does not contain grinder settings - you set those yourself using the dial behind the water tank! You can also control the strength of your coffee by using the right water level:
45g of beans (around 3 tablespoons)
Light Coffee > 700ml
Optimum > 580ml Strong > 500ml or less
50g of beans (around 3.5 tablespoons) Light Coffee > 770ml
Optimum > 650ml
Strong > 600ml or less
The key is to play around and taste what suits yourself! Rock on!
