I use different beans in my Mazzer Super Jolly, a stepless grinder, and rotate through up to 4 different varieties of beans and as many or more blends in a single day. Ive found that once I got used to the grinder and the beans its pretty easy to adjust for different beans as well as adjusting for temperature and humidity variations through-out the day.Originally Posted by sdavies link=1158321141/0#0 date=1158321140
Personally as a coffee snob who wants a God Shot every time I would never go with a stepped grinder. That said if someone has lower end espresso equipment, a loose fitting tamper, or cant judge their tamping pressure very well wouldnt be able to utilize the fineness of a stepless grinder to its full potential, and it may well be a detriment to them as theyd end up chasing the right grind.
If one has middle to high-end equipment with a proper fitting tamper and is able to reliably reproduce the tamping pressure they will be able to take full advantage of a stepless grinder. On the other hand people in this situation would also be able to get consistantly good, perhaps even great, shots with a stepped grinder with small steps by adjusting the dose/tamp slightly.
If one is not using the grinder for espresso then a stepless grinder would be perfectly adequate to the task.
My advice would be to not stint on the grinder. A great grinder will allow you to make great shots with a marginal espresso machine. A poor grinder will make it a nightmare to pull great shots even with a commercial espresso machine.
