Tale of the Tape
In the Max, Cimbali is reviving the conical/flat burr-set from the fabled Alinox-DRM grinder. There are a few changes. The Max is housed in body of the Junior grinder, a 64mm flat burr. This means that the original 68mm planar has been shrunk down slightly. Since this changes the inner diameter, the conical section, which acts as an augur to force the beans into the flat burr, is also slightly smaller. Finally, the direct drive 350 watt motor from the Junior has been retained, so the grinder spins at 1800rpm, rather than the geared down speeds of the conicals. As in the original burr-set, using a conical stone as an augur allows one to eliminate the widely spaced grabber burrs on the inside of conventional planars, and increase the actual grinding surface. The increased distance the bean travels means it is reduced to powder more gradually, and presumably, with better uniformity.
The Max is a pure espresso grinder; converting it to a single dose, all purpose grinder would take more than the usual amount of hacking. It might be doable, but the other grinders in this test are far more suitable for this than the Max. On the other hand, the look and size of this grinder are a lot more counter friendly than any of the large conicals and even of most 64mm flat burr grinders. I have to admit I'm not fond of the way this grinder is set up, since I prefer grinders that can be used general purpose; but as a pure espresso grinder, the form factor is outstanding.
The Max is a fairly loud grinder when running empty. However, this is not much of an issue, since single dose operation is not really possible, and since it quietens down to roughly the same noise level as the others when grinding beans. The clacking of the doser is the quietest of any grinder in this test. Given its use as a pure espresso grinder, my only beef is with the hopper. The funnel leading to the burrs is substantially narrower than the throat of the grinder, and does not go all the way down. Consequently, the beans jump back up, miss the funnel, and land in the ledges and gaps between the hopper and the grind chamber. In there, they play a game of bean-billiards while the grinding goes on. The only way to prevent this is to grind enough beans so that these nooks and crannies get jammed up with beans and bean fragments, roughly 15 grams worth. If purchasers of the grinder find this waste unacceptable, they can easily and invisibly modify the existing hopper, by extending and widening its exit funnel with some tubing.
For the purpose of this test, I cut a disposable cup so it fits snugly against the static outer burr, and used that as a hopper. I kept this hopper adequately filled to prevent all popcorning, partly in deference to Ken, but mostly because the geometry of the grinder's throat does not allow for an effective way to press down a single dose of beans.
The Fight
The Max pours more steadily than the Mini or M3, but not quite as well as the big conicals, and I had to keep my eyes closed early in the shots to keep the tasting blind. But this did not affect the shot taste.
In the first round, today starting with 13.5 gram doses, I had a huge surprise; one of the cups was a god shot. The cinnamon from the Biloya, marzipan from the Yellow Bourbon and Cenaproc, and the sherry cask from the aged Sumatra came out well-integrated but gloriously distinct as well, as did the floral honey of the Biloya dancing up top. The shot's flavors shimmered on the tongue, and I would have scored it a 5 to 5.5 in competition. It wasn't difficult to guess which grinder it came from, since the Robur was its reliable 4 point self. The Robur won the body category by half a point with a hint of extra creaminess. First round to the Max with a surprising 4 points.
In the second and third rounds, whatever lightning struck was gone, and the two pairs of shots were dead even in taste at the usual 3.5 to 4 level. In the second round, the Max's balanced a little brighter, but it didn't affect the overall quality. In the third round, the tastes were indistinguishable. In both rounds, as in the first, the Robur was slightly creamier in body. After the first shot, I had cut a cup and created micro-hopper for the Robur, ready to eat crow and admit popcorning detracts from quality. But, alas, god-shots are not so easily wrought -- the change from a piston to a hopper made no difference whatsoever except for slowing down the pour by a few seconds.
In the fourth round, the Max produced a very good shot, although not the great one of the first, with slightly more clarity in the taste, and, surprisingly at this point, a creamier body. It won the round by 4 points.
I don't much like this grinder, but so far, it's done the best in the beat the Robur stakes, splitting the rounds and winning by 4 points. It is not a distinctly bright grinder, like the Macap MXK, nor a laid back one like the Compak. My early sense of the Max, relative to the other Titans, is that it does an outstanding job with the middle flavors: caramels, nuts and woods, reproducing them with great clarity. However, this is my first full day with it, so this is still very tentative.
