12.3 Tips for good coffee drinks
NOTICE
Poor drink quality
The oil from the coffee beans is deposited on the inside of the bean hopper as a thin film of oil. This deposited oil
ages quickly and impairs the taste of the drinks produced.
a)
Remove the oil film from the inside of the bean hopper on a daily basis.
b)
To do this, use a dry cloth or a cloth moistened only with water.
c)
Do not use any cleaners, as these alter the taste of the coffee.
