Beverage consulting refers to advice in a particular area of the beverage industry. With start-up beverages, product development and consulting services are particularly efficient and cost effective as formulating new products and addressing quality control and processing issues requires much expertise. This expertise is necessary as formulation and production varies for the diverse group of beverages including fruit juices and juice drinks, tropical nectars, carbonated beverages, energy drinks, diet and nutritional beverages, flavored waters, and sports drinks. Additionally, nutritional information, ingredient list and any applicable allergen statement must meet all legal requirements. Handling many of the complexities involved in the beverage process, consultants help manufacturing companies with everything from iced tea beverages to bottled spring waters.
