Wine certification is often assessed by physicochemical and sensory tests [9].
Physicochemical laboratory tests routinely used to characterize wine include
determination of density, alcohol or pH values, while sensory tests rely mainly
on human experts. It should be stressed that taste is the least understood of
the human senses [20], thus wine classification is a difficult task. Moreover, the
relationships between the physicochemical and sensory analysis are complex and
still not fully understood
