Wine industry researching grape marc as stock feed to mitigate climate change

The Australian wine industry is investigating ways of turning winery waste into stock feed to reduce methane emissions from livestock. Grape marc, the waste left from crushing grapes, is known to reduce methane production in the rumen when fed to sheep and cattle. Senior winemaker at the Australian Wine Research Institute, Geoff Cowey, said the research was being driven by the livestock industry’s goal to reduce its environmental impact in the light of climate change.
