This study examines consumers' willingness to pay (WTP) for mountain wines and assesses the potential impact of extending the EU quality term "mountain product" to the wine sector. A discrete choice experiment was conducted with 256 wine consumers from the Veneto region (Italy). In the experiment, participants were presented with various wine options with different attributes, including a mountain designation, organic certification and price. The multinomial logit model was used to analyse consumer preferences and estimate WTP. The results show that consumers have a positive WTP for mountain wines, especially in combination with organic certification. Price, mountain designation and organic certification were the most influential factors in the decision-making process. In addition, environmental awareness and the perception of mountain wines had a significant impact on consumer choice. These findings provide actionable insights for policymakers and producers, highlighting the potential of the “Mountain product” label as a tool for sustainable rural development.
