My bialetti brikka claims to be a 2 cup espresso maker. However, I only see one water fill line. When I use this line, it produces one cup of espresso. I thought there might be a second fill line for the second cup. Is it implied that I would fill the water line and pour into the base twice to achieve a 2 cup espresso? Won't this throw the whole ratio of water to heat to time ?
Any insight is greatly appreciated.
