Haze forming proteins (HFP) are plant pathogen related and fungicidal thus they should not be downregulated. Mechanical harvesting and prolonged juice contact increases HFP. Protease treatment may reduce bentonite requirements. ELISA assays were developed which are too sensitive for winery use. ESMS of wine proteins can determine varietal origin of the grapes in the wine.
