At this point, my routine is pretty much dialed in (pardon the pun), and is quite uncomplicated. Everything is on autopilot. I’m not operating at a very high level. A small amount of effort initially was all it took to get very good results. If I ever feel the need to get deeper into this hobby, the option is always there, and it will probably be there. As a hobby it’s a nice one, because there are lots of little ways to tinker. I could get a bottomless porta filter and play with that. If I really wanted to be spendy, I could get a manual espresso maker.
I haven’t worked as a barista before. I think maybe working as a barista causes you to have an unhealthy and sort of extreme relationship with coffee. If you are deciding whether to get deeper into coffee or not, as a non-barista, I can say that has been a lot of fun and a good way to save money.
