Hello - I have a Gaggia Classic and want to pull a 20 gram dose. I think I am pushing the limits already by putting an 18 gram dose in the stock double basket. I wonder if the 20g VST basket will fit my stock portafilter. I have one of the newer machines if that makes a difference in portafilter size.

I'd like to know what other folks are dosing in their stock double baskets too.

I think the VST18 is the max size (i have two)

However, the good news is you can grind finer with the VST so you may not need so much coffee.
