Looking to add a bit of pizzazz to my coffee making, just because. Do bottomless portafilters add anything to the experience other than looking mighty cool? I'd assume it would help me work out if I'm getting channeling?
Also, any decent scales around? The cheap ones I got are fine for weighing but they're a bit slow when it comes to actually timing the shot as it jumps up quite quickly.
They help with technique but can be a bit of a rabbit hole chasing perfect visual pours especially if you use VST baskets that are fussy about puck prep.
The main reason I use it all the time is it allows a bigger mug under the filter with scales. I drink mainly 21g triple shots so for those I pull the shot directly into a mug and top with water or steamed milk.
