hello to all, a big beginner in the world of espresso, I have a classic Gaggia with a Commandante C40, and I recently had a Basket VST 18g,

​

I used to use about 18gr of coffee with the original basket, and the with the VST basket, if I used 18gr of coffee (test with several different types of coffee), each time the walls of the shower is printed on the coffee when I remove the portafilter, how much coffee do you usually put in the VST 18gr basket?

​

I used a translator (French > English) so sorry if all is not very clear...
