I'm seriously looking at buying a all in one system. But I have heard that a Corona style mill's crush does not work well with an all in one system.
For those using all in one systems, is in necessary to upgrade/change to a roller mill?
I use a robobrew and a corona mill and I haven’t had any problems over the last 4 years or so. Someday I wouldn’t mind upgrading to a roller mill but I haven’t had a dire need to.
A Corona style mill will work fine. One advantage of a roller mill is the ability to mill directly into the mash basket (at least IMHO it's an advantage). That may not be possible using a Corona mill given the need to clamp it down.
I finally figured out that I can tie my brew bag to my Corona mill using a wire tie and just mill right into it.
Maybe one can use just rice hulls when using a all in one.
