HarveyMushman And switching between methods regularly isn’t an issue?
No. I switch between pour over and espresso every day. Find dialling in for espresso with new beans very easy. I have a default setting - 1.0 on mine. I will tighten the grind if the shot is too fast and do the opposite if to slow. I can usually nail follow up shots at the second attempt. That said, even 15sec shots aren’t undrinkable but that’s maybe me and my taste buds.
The big plus about the EK is its ability to push extraction yields well above 20% - 23-24% with relative ease. This unlocks the beans sweet elements which help tame the acidic notes associated with lighter roasts. So you can get bags of fruit without it being mouth puckering.
