Concentration: density, not quantity

The standard

Perceptible density measures the substance per volume, not the total amount in the glass.

Criteria

  • The substance is judged per volume, not as a total quantity
  • Concentration is independent of alcohol and body
  • It shows in the fullness of flavour, not in its force
  • It is derivable from the extract, not from the label

Distinction

Concentration ≠ extract: extract is the measurable mass of dissolved solids, concentration its perceptible density on the palate. Perceptible density translates the measured value into the sensory impression. Concentration ≠ power: a wine can seem dense without being forceful.
