These portafilters fit all commercial La Spaziale machines as well as the Lucca A53, Lucca A53 Mini, Mini Vivaldi, and the Vivaldi II. This portafilter is cut out by the manufacturer so you will notice the nice chrome finish on the bottom. Included with the portafilter is a La Spaziale Triple Insert Basket.
Bottomless portafilters allow the barista to visually assess how evenly the coffee extracts through the basket. Imperfections in dosing and tamping technique are exposed when the coffee spurts out in different directions instead of straight down into the cup. This is known as channelling. It can be a little messy to start with but is an invaluable learning tool for any espresso aficionado.
