In 2020, public and private life in Europe has been undergoing drastic changes due to the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To contain the spread of the virus, many national governments have introduced measures to limit physical contact, which are also likely to affect health-related behaviours such as alcohol use. The objective of this study is to investigate changes in alcohol consumption during the SARS-CoV-2 pandemic. This project resulted the collaboration and commitments of public health scientists from more than 20 research institutions from all over Europe.
