Is a 58mm Bottomless Portafilter a Necessity?
While they are not a necessity we routinely recommend them to pretty much everyone, especially those who have never had a prosumer machine before.
Why?
They are incredible learning tools.
Bottomless portafilters allow you to see your extraction from start to finish and give you a great idea of what you're doing right, and more importantly wrong, with your coffee preparation.
Being able to see your extraction from the first drop will tell you tons of information about your grind size, dosage, tamping pressure, basically all the variables in the espresso making process!
