A 25-year bibliometric analysis of the management of sparkling winemaking processes: innovation trends and future research agenda

Purpose Over the past 25 years (1998–2023), a significant body of scientific research on sparkling wine production and related processes has been documented in the Web of Science and Scopus databases. Design/methodology/approach From an initial pool of 2,414 references, a rigorous selection process was used using the PRISMA methodology, narrowing the focus to 103 key publications. A bibliometric analysis, conducted with the Biblioshiny package in RStudio, was used to quantitatively and qualitatively evaluate the selected peer-reviewed documents. Findings The results reveal significant innovation trends, particularly in temperature-controlled fermentation and automated bottling processes. Originality/value This research not only traces the development of scientific knowledge in sparkling winemaking, but also presents a roadmap for future technological investments and innovative insights.
