The Breville / Sage Oracle has a grinder, steam wand and espresso maker (not sure if there is a more technical term for the part where you click the portafilter into) in one machine. Online advertisements show it can steam and brew at once because of the double boiler.
I am more interest in brewing a few shots in succession*. Can this machine grind and brew at the same time? I'm assuming one has two portafilters at hand.
*I know the grinder heating up may cause the grind size to change.
