Title: Characterization of ethanol emissions from wineries

Principal Investigator / Author(s): Fielder, David

Contractor: EAL Corporation

Contract Number: A0-071-31

Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources


Wine industry ethanol emission factors have been determined with emphasis on the fermentation process and fugitive emissions. Information has been gained from winery surveys, an extensive literature search, and actual source testing of fermentation exhaust streams and suspected fugitive emission sources. Wine production in California may be characterized by methods and materials employed in two general regions. One is the warm Central Valley where the larger standard table and dessert wine producers typically harvest and ferment high sugar content grapes. In contrast, the northern coastal counties and Napa Valley are conducive to the production of premium wines, which are made from slower maturing grapes, grown in a unique microenvironment of moderate temperatures and sunshine.
