Wine filter

Innovative Technologies for Wine Production

Wine is a complex product, each with a unique character that must be preserved during manufacturing and until the bottle is opened. Filtration is critical to both the appearance and stabilization of the wine by removing fermentation products and microbial content, but the filtration process must not alter the flavor, color characteristics and complexity of the wine that makes each unique. Wine production requires a range of filtration technologies to manage microbial contamination prior to bottling, capture diatomaceous earth (DE) used in upstream processing, manage air quality in production and in holding tanks, provide clean water for washing, rinsing and sanitizing, and to protect the membrane filters used in the bottling process. Graver Technologies provides the necessary support along with a wide selection of filters to help wineries provide a consistent quality product with the economics necessary to achieve success.
