The demand for low- and non-alcoholic beverages is booming, driven by evolving consumer preferences for healthier, more mindful drinking options. But behind this innovation lies a complex challenge: without alcohol’s natural antimicrobial properties, these beverages face a higher risk of spoilage and contamination. Ensuring product safety, shelf stability, and regulatory compliance requires more than careful brewing—it calls for the expertise of a qualified process authority. Here is a look at the key risks, essential testing protocols, and proven strategies to keep your low- and no-alcohol products safe, high-quality, and market-ready.
