It may appear to be an obvious statement to make, but a label attached to a jar or bottle has a simple and very basic function; to describe what is in the container, provide branding for your company, plus there may be some legal requirements too.
For example, some of the statutory requirements would include; on alcoholic beverages need the name and address of supplier or bottler, country of origin and in the case of wines France or Blend of wines from Italy, Spain and Portugal. The all-important quantity within the bottle, the alcoholic strength and the use by dates are just some.
