Functional beverages are a growing focus in food research, as consumers increasingly seek products that offer potential bioactive and nutritional advantages beyond basic nutrition. Examples include kombucha, kefir, fortified juices, herbal infusions, and artisanal fermented drinks. This study presents the development of four functional fermented beverages: a kvass, an elderflower socată, cider sparkling drinks, and an elderflower liqueur. All products were developed under laboratory conditions using local ingredients and controlled fermentation or maceration. Physico-chemical parameters (alcohol content, acidity, pH, residual sugars) and sensory attributes were evaluated. The formulations aimed to improve both nutritional quality and consumer acceptability. Although these beverages are widely consumed, there is limited research on their functional properties and potential health benefits, particularly when using local ingredients under controlled conditions. The results highlight their potential as sustainable, health-oriented, value-added functional beverages with market relevance. This research demonstrates how traditional beverages can be revitalized using local resources and modern processing techniques, contributing to both functional food innovation and the development of regionally distinctive products.
