Currently using an Encore that I've tweaked to grind a reasonably good espresso.
The thing I dislike about the Encore (and presumably the Virtuoso) is I don't get crisp, defined flavors unless I remove the hopper and outer burr and brush out the burr and inner burr. Then I hit it a few times to knock out the loose grinds stuck in the chute. THEN I can make coffee. When I don't do that, the flavors are very subdued. It took me about 3 months to figure this out when I first got the grinder. I was a little unimpressed at first but once I started cleaning it out each time I used it there was a significant improvement.
That's why I really like the Sette - no grind retention.
Speaking of Baratza working on new burrs, they said they may but they haven't begun working on it yet. It seems to me there is definitely a market for it so the demand is there but I don't know if they'll do it.
The Vario sounds nice, but I don't really want to spend the extra money. I'm also not sure it would give me both a good espresso and brew grind.
So, those are some of my thoughts but I'm interested to hear anyone's input.
Well, I love my oxo but it's not gonna work for you. It doesn't do a very good espresso grind, the burr isn't exchangeable with other types, and it might not dissassemble as far as some of the other grinders. But I do drip almost everyday, and occasionally a pour-over when I'm trying something new. The medium grind is just right for that.
Why do I like it so much? I love the integrated scale. It grinds until it hits a specific weight. regardless of the grind settings, I always get the same weight. For me, that's a good thing.
