On my Rancilio portafilter, the spouts are not aligned with the handle (I would expect them to be in a 90° angle). In consequence, the spouts do also not really align with the machine when the portafilter sits in the grouphead. Is there a specific rationale behind this?
The spouts are aligned with the machine front and cup once the portafilter is installed for use in the machine. Note the handle on the portafilter body goes quite a distance over to the side, or it would interfere with handling the cup.
