This process increases intensity, mouthfeel, and depth by 5–10% while maintaining the wine’s balance and quality. Designed for on-site use and ease of integration into winemaking operations, this technology is especially effective for enhancing cooler-climate vintages or lots diluted by rain, elevating good wines into standout, richly textured expressions.
