The Milk Island has a capacity of 13.5oz and is easy to take apart and keep clean. This helpful accessory is made specifically for the Platinum line of Gaggia machines. If maintained correctly, it can give you the consistency of manual frothing without the fuss. Simply pour cold, fresh milk into the pitcher, connect it to the base and turn the steam knob. When the milk gets to the desired temperature, turn the steam knob off and you are done.
