I have been using a Rio (Mazzer) Super Jolly after buying it used 8 years ago. I have since replaced the burrs, the timer switch, and converted it to a funnel setup, rather than the doser with which it came. It has been a great machine from what I can discern, with the only drawbacks being what is often cited here....grinds getting caught in the horizontal chute as well as wasted grinds since we aren't single dosing with the grinder. I avoided doing that because of popcorning concerns, although I've read several articles now that contend that popcorning isn't all that big an issue.
In any event, while I have been looking to upgrade our espresso machine (HX to DB) in hopes of getting more consistent and delicious shots, I wondered if it was worth it to upgrade the grinder as well. There is obviously a lot of love for the Niche Zero, and it seems really cool. It would allow us to eliminate waste, which is nice, and it seems quieter and just overall a nicer setup for home use. It's also fun to upgrade the entire espresso setup, machine and grinder. I assumed that it would be a worthwhile consideration, but thought to check in with the brain trust here
Granted, the Super Jolly is a flat burr grinder, and the Zero is conical, and from what I can tell, flat burr machines are generally considered preferable for espresso grinding. We currently just grind for our espresso (lattes to be specific, not currently shot profiling), although I guess it would be nice to be able to grind for french press every once in a while too. I gather that I could keep two grinders operating, one dedicated to each grind, but we really don't have the kitchen counter space for that.
Bottom line, do you think upgrading from a Super Jolly to a Niche Zero will produce a significant enough shift in what's in the cup to validate the $600+ investment? Super Jolly gets a lot of love in the HB archives for its adaptability, but it also sometimes is described as a good "entry" grinder. I have read into the NZ thread, although not all 100+ pages of it. I guess this is more a question of people's evaluation of the Super Jolly and the anticipated benefit of upgrading. Thanks for insights.
