How voluntary information can help consumer’s choices: an Italian vinegar producer company case study

The aim of this paper is to analyse the strategies of voluntary information and quality certification in the vinegar sector, a globally renowned Italian industry, to identify new labelling practices for voluntary information. To achieve this objective, a case study on Ponti S.p.A. was conducted. The research outlines the labelling structures of three main products. The company's approach provides consumers with information related to quality characteristics, which is advantageous for them. This is a unique case in the vinegar market sector, to the best of the authors' knowledge. However, the study has some limitations due to the applied methodology.
