The innate appeal of shape.
The classic square ice cube produced by Kold-Draft ice machines, possesses many qualities that make it a superior ice form. It is the largest cube available in the USA that is made in a commercial ice machine, and it is the only truly square cube as well, and this statement includes the ice made by the Hoshizaki copy of a Kold-Draft style machine. The Japanese facsimile makes ice that is smaller, is not square, and has a dimple so large that they actually need to incorporate it in their ice cube diagram. Further, while Kold-Draft offers a Baskin Robbins like 31 versions of classic cube ice machines, Hoshizaki offers only one. And with ice machines, one size does not fit all.
Back to the shape. With no knowledge of any supporting scientific evidence, I propose that certain shapes offer more of an aesthetic appeal than other shapes, and this is even more accurate when considering the shapes of ice cubes available through the major commercial ice machine producers: Ice-O-Matic, Hoshizaki, Manitowoc, Scotsman, and Kold-Draft. For starters, let’s take a look at the offerings from the three manufacturer’s that produce the same basic ice style: Ice-O-Matic, Scotsman and Manitowoc. Aside from a couple of very small import models, the ice cube shape these manufacturers make and which represents the overwhelming portion of their brands is called “rhomboid”. That might even be accurate if the “rhomboid” ice they produce did not include an extra protruding layer on one side which is known as the “bridge” or “hat”. The reason for this additional unattractive ridge is that this ice is made in a vertical evaporator where all the cubes are attached to each other on one side, and at the end of the freeze cycle, when this grid-like slab drops into the bin, it is supposed to be broken up by impact, but often results in pieces of ice that are not individual cubes at all, but look more like a multi cube ice waffle representation of the State of Tennessee. Hoshizaki, as mentioned in the first paragraph above, does make one model that aspires (but fails) to be square, but their main ice cube offering is described in their literature as a “crescent”. This may be a convenient term, but it is not, by any known definition, a crescent. As a matter of fact, there is no name for the shape of a Hoshizaki ice cube, but a better description would be “a lengthwise slice off of a cylinder”.
And Kold-Draft makes a cube. Clean. Simple. Individually harvested. Square. This is the only pure cube in the geometric sense that comes from a commercial ice machine. Six sides of equal dimension. 90 degree right angles. A true cube, like a sphere, is an indication of perfection. It seems to contain an intrinsic appeal that seduces aesthetic perception and causes a subliminal attraction. Plainly, a cube is just a better shape for a cocktail than a 14 sided extra layered rhomboid or cylinder sliced lengthwise.
