WHAT IS A PORTAFILTER SPOUT?
The spout is the “swoop-like” portion that you see on some portafilter models. Depending on whether it’s a single, double, or triple there will either be one, two or three spouts. These spouts help the espresso flow out of the portafilter more evenly. For example, if you’re pulling a double espresso shot, having two spouts will allow the espresso to flow evenly into two cups. If a portafilter does not have a spout, it’s considered to be bottomless or naked portafilter.
