Ok, so I pulled out the old Innova ( pictured below with my old Venus before I upgraded to the Vetrano and my Elektra ), dusted it off and fired it up. For some reason, the one hopper I had with it wasn't cracked or chipped yet, and seems to be hanging in there. I didn't know where the heck I had it adjusted to, so took it down to where the burrs are about as close together as I can get them and back it off about 15 turns. The first shot out of my Vetrano.....did not come out. Ok, so after flushing the machine, I backed off the grind adjustment on the Innova another 15 turns or so, and pulled a teensy wheensy little ristretto. Tasted roasty sweet, but the extraction rate was too restricted. So after another grind adjustment, I pulled one of the finest looking ristrettos ever. There was far more tiger striping, mottling, oils apparent, and texture. The flavor was intense sweet roast. Let's put it this way...the difference from a mazzer mini grind in the shot, vs a shot pulled from my Innova conical burr grind was astounding, visually especially during the pull and in the cup, and also on the nose and palate.
I then made a latte, and did not experience any noticeable difference in the flavor, but it did seem to be much smoother, with no bitterness discernable. It was so smooth, in fact, that it seemed unremarkable. Of course, having just consumed straight shots minutes before may have something to do with this. Which leads me to the questions I have regarding cupping...how can you objectively evaluate flavor profiles in subsequent tastings after already tasting coffee samples? and what about what you ate prior to cupping, and...ok, I won't go there.
By the way, I noticed that Espresso Parts NW carries parts for the Innova, and that its new trade name is Ascaso. Since they're only 20-30 minutes drive from my house, looks like I'll be able to keep that Innova going for awhile.
Anyway, I found that I had room to situate my Innova between the Mazzer and Vetrano so there it now sits. Since it's polished aluminum, it fits right in. I have decided that for straight shots, americanos, and non milk espresso drinks, I'll use the Innova for now.
