It's a great grinder for low to medium volume in a cafe. Espresso Parts has the Mazzer Major with the electronic dosing which is pretty sweet. We have a Super Jolly at the school without the electronic dosing and it is great, but I feel like I am adding too many steps and risk wasting too much coffee manually, after using the doser e. It may be worth the extra $ to go electronic and with a Major.
You're hearing it over and over... super dependable, solid workhorse, but a little slow for busier cafes. I believe the grinder Terika is speaking of is the Mazzer Major, but the non-electronic version, I could be wrong.
Currently I'm working with two Super Jollys and two Majors. Depending on what coffees we are running the Majors can be up to almost twice as fast. Specifically we are running one coffee at 7.2 seconds for a 19 gram dose (Super Jolly) and a comparable coffee at 4.9 seconds for a 18 gram dose (Major). This is the closest they have ever come. Both work wonderfully, but while it's very possible to out-pace a SJ, it's pretty difficult for me to out-pace a Major.
I would rather have a Major over a Super Jolly in Any application. Burr size makes a Huge difference - in grind quality as well as time. I even prefer the Baratza Vario over the Super Jolly. Major all the way if possible!
Thanks everyone for your thoughts. It's true, burr size and speed of the grind seem like obvious questions. The relation to how that directly affects the Barista handling the counter can only be told by one who has used the machine.
So thanks again for all the first hand knowledge.
