Viscosity: flow resistance, not merit

The standard

The measured flow resistance judges viscosity as a physical quantity and separates it from impressions that have other causes.

Criteria

  • Dissolved sugar and alcohol raise the flow resistance measurably
  • The palate impression of fullness is not the same as measured viscosity
  • It says nothing about merit, only about composition

Distinction

Viscosity ≠ tears: the streaks running down the glass wall arise from evaporation and the surface tension of alcohol, not from flow resistance. Viscosity ≠ body: the body is a composite overall impression, the measured flow resistance only one of its components.
