WHAT THIS REPORT IS

A global report designed to challenge and guide how the wine industry understands and engages with water.

Informed by science and grounded in real-world practice, it reflects a community-driven effort bridging academia and wine production.

WHY IT MATTERS

Water is becoming less predictable, more contested, and increasingly central to how wine is produced.

This report shifts the focus from managing water as an input to understanding it as part of a living system — shaping how decisions are made across vineyards, wineries, and regions.

WHAT MAKES IT DIFFERENT

Built by the Porto Protocol community, the report bridges scientific knowledge with lived experience — combining expert insight, real-world case studies, and practical application.

WHAT YOU’LL GAIN

• A broader understanding of water beyond efficiency
• Insight into how systems shape water availability
• Practical perspectives from wine regions worldwide
• Tools to support better-informed decisions

What's Inside
