I'd been jonesin' for a Baratza Vario for a while and was putting off the expense but that changed after I wanted to serve a bunch of coffee at a party. I have the Hario mini mill that I love, but it would take a lot of work and time for me to grind coffee for several people using the manual mini mill.
Enter the Baratza Vario-W; the "W" stands for weight. It has a built-in scale that weighs within a tenth of a gram the ground coffee. You can have three preset weights and with the push of a button, get the target weight in ground coffee.
I should also mention that I had to test Baratza's support service immediately, as the grinder came with the wrong grounds bin. After a very short call with their support line, they had another bin in the mail and an email confirmation to me with a tracking number. In a couple of days I had the new bin and was off to the races.
The other thing I really like about this grinder is the ease of transitioning between grind profiles. The slider on the right is for macro changes that will go from an espresso fineness to a sea salt coarseness and the slider on the left is to fine tune that level even more. It also comes with a heavy-duty metal wrench that allows you to further tune the grind so that you get just the right grind for whatever you're brewing.
I still use the mini mill and still enjoy it — I feel more connected with the coffee when I use it because it allows me to feel how tough the beans are to grind, which is one indication of the roast level; darker roasts further break down the cell structure, making the coffee much easier to grind. But for volume and ease, I now go straight for the Vario.
