Wine Filtration

Each wine has a unique character that must be preserved.  While filtration is needed to remove fermentation products and microbes that can cause spoilage, the filtration process should not alter the flavor and color characteristics that make that wine special.

Graver successfully achieves this objective with a range of prefiltration and final filtration products.
