All our baristas routinely use these.
This one is only for 53mm portafilters, but we can also order in 58mm if needed.
Place the tool onto a filter basket with the correct dose of fresh coffee grounds, then push down and twist clockwise. The angled underside distributes the grounds evenly to help improve consistent extraction. We follow this by using a tamper, very useful if you are a perfectionist and you want to make great coffee and improve consistency. Professional grade product.
