I am torn between to grinders – the Baratza Preciso and the Baratza Vario. Both grinders have many fans and a few detractors. I like the simplicity of the Preciso compared the Vario. I do not think I would have any trouble with the Vario that couldn't be resolved though.
I guess my desire for either comes from wanting a single dose grinder - I have enough coffee laying around at any given time to justify multiple espresso grinders. My larger grinder works better for me with some bean mass above the burrs so I load and reload till the bag is empty. I can change over beans but this means either wasting a decent amount of coffee to empty the throat of the grinder. I would rather continue grinding the same bag in that machine while adding some variety by single dosing here and there.
I like what I hear about the fluffy grounds and zero retention with the Vario - these are the main points of interest for me. I heard the Preciso clumps a bit and that the shots have brighter flavors accentuated. The brighter flavor might be interesting for variety, but the clumping could prove bothersome. I have a Virtuoso for non-espresso grinding which I like very much. Knowing the Preciso shares similarity with this work horse is a plus. The new grinder (either one) does not have to replace the Virtuoso for non-espresso grinding but if it can go from fine to coarser and back without losing it's settings this would be nice - nice but not a requirement for me to be happy.
I like the idea of ceramic burrs for longevity as a concept, but in practice even if the steel Preciso burrs are only good for 500 pounds this would be around 20 years use for a secondary household espresso grinder for me. I would hate to shoot a rock through the Vario. I have found them in beans from good roasters so in 20 years it could happen.
Both look like decent grinders - I guess that is why this decision is so tough for me.
