Like some others, my (Sage Oracle) machine turns off after 20 minutes but stays pretty hot for quite a while after, so it comes up pretty fast from there. I used to have it coming on in the AM on timer when my routine was more or less fixed but now, I just try to turn it on (or get the Mrs to, if she’s closer) about 15 mins before I want it. It only takes about 5 mins from cold. As I have 1 or 2 cups most days, 3 or 4 at most and sometimes 0 cups, and at varying times, it’s pointless using the timer.
Sure, it’s not cheap in power these days, When was proper coffee ever a cheap habit? The coffee itself isn’t exactly cheap, and as for the machine, and all the ancilliary bits …. well, ouch.
It’s just a bit more expensive now than a year or two back.
