As we look back on 2025, one thing is clear: innovation didn’t slow down, it got sharper. Across major food, beverage, supplement, and ingredient tradeshows this year, the conversation shifted away from flashy novelty and toward proof, performance, and practicality. Here is our perspective on what to expect in 2026.


How do you know when it makes sense to bring in product development support and when it doesn’t? Based on what we see across brands, ingredient companies, and startups, here’s a practical way to think about it.


The rapid rise of mocktails and alcohol alternatives signals a deeper shift in consumer behavior. As the category matures, brands are discovering that removing alcohol is only the beginning.
