Oat milk kept accelerating in recent years, with global shipments reaching 4.9 million tonnes in 2023 and US retail dollar sales in 2023 estimated at $7.7 billion. At the same time, the market is being projected to grow much faster ahead, including a 29.2% US CAGR forecast from 2024 to 2030 and a €11.5 billion European plant-based food and beverage market target by 2030. The twist is that demand metrics like penetration and purchase rates often move alongside hard-to-see shifts in sustainability and labeling rules, which can change what producers bring to shelves.
