It's similar to specific techniques, like Sound Release's Inner Sonar Skill, but always active. Unlike skills, this ability is basically an enhanced form of a sense that any animal possesses and, as such, is always active and unconsciously controlled. It works by passively engrossing the chakra flow around the mouth, throat and tongue areas, associated with Taste, augmenting their sensitivity, like the Sonar Skill increases the chakra flow around the ears.
This permits the user to acquire a super-human sense of taste, allowing one to sense even the faintest remnants of substances and pinpoint their origin, concentration and nature and, through this ability, the user acquires the ability to taste chakra itself.
Every person has a unique chakra signature, which leaves behind a unique chakra taste. Simultaneously, each element stimulates different parts of the tongue, and is thus associated with the different base flavors ( Sweet - Fire, Sour - Wind, Bitter - Lightning, Salty - Earth, Savory - Water ), which can then complexity into the advanced Elements. The Ganmi's taste sensory perception is heightened and quite dexterous. A Ganmi is able to taste the different concentrations of a sample, in order to gauge the quantity and distance from the taste source, as anyone would a smell or a sound, for example. The nature of the taste, is associated with a taste map, every chemical and mineral will activate a different cell, which will be associated with several taste groups. Each individual taste will activate more than one taste group, and the brain will come to the conclusion of the nature of the taste through this cross checking. A lemon may activate group B, C, D and not A, and that is the composition of what the brain perceives as Lemon. The more exposed a Ganmi is to the elements, the more complex their taste map is. An unknown taste will still activate a specific set of groups, and it is up to the user to associate with with something, for future reference.
This, of course, makes their chakra nature sensing, while quite better than sharingan's, still similar, in the sense that there is not a direct link to a chakra nature, as if each had a specific taste ( or color in the sharingan's case), which it actually doesn't have, but it does allow an experienced user to deduct it quite accurately ( through heat, ashy smell, carbonization, etc for Fire, liquidy, mineraly, wet and cold for Water, etc etc ), along with other sensory cues, like sight, sound, etc.
The complexity of the Gamni Taste is similar to that of other advanced chemical-sensor animals, such as the highly advanced dog smelling sense. Emotions are nothing but hormonal and chemical unbalances, and even dogs, with their subpar intelligence, are able to innately distinguish a wide range of emotions in other animals, humans inclusive, from Happiness to Fear, Sadness to Excitement. It's a fusion between body language and heightened sensory. A panicked person will sweet more, which the dog is able to smell. Lust will invariable release sexual hormones, that, while not as noticeable as pheromones in other species, are still there and noticeable to someone with heightened senses. Gamni thus ally their animalistic advanced senses with the human innate brain capabilities, to bring these Emotion sensing to new heights, in a much more complex sensory map than dogs, capable of greater empathy and thus, better distinguish the nuances of similar emotions.
Restrictions:
Every chakra signature is different and individual, and so is it's taste..
Every chakra modulation is distinguishable by user, quantity, nature and type.
Basic Chakra, Elemental Chakra, Bijuu Chakra, and other type of chakra related energies are able to be tasted, even if the user can't access them or is able to understand or define them.
Non-Chakra related Energy sources can't be tasted unless they come from a chakra-requiring technique, this only entails alternative spiritual sources, like untouched Force, or un-gathered Natural Energy, for example.
The user is able to taste certain emotions or conditions in people, similar to other animals with highly advanced chemical senses (like Dogs). They thrive in it and developed the Taste Genjutsu with it.
The power and range of the sensory technique varies with the rank of the user both in power and in the clan.
According to the speed chart, Ganmi's natural prowess would be somewhat equal to that of an Inuzuka clansmen, thus 1.5x. Upon reaching the highest level within the clan, this ability is increased to x3, similar to that of Emotion Sensing.
