How can carbon offsetting claims in the wine industry be a form of greenwashing? How does the natural fermentation process in winemaking create one of the most concentrated sources of CO₂ emissions in any industry?

How do these issues of climate change and sustainability affect people's lives beyond the vineyards? Key Takeaways How can carbon offsetting claims in the wine industry be a form of greenwashing? For a consumer, I would be suspicious of anyone who is using carbon offsetting to claim they're carbon neutral. The company will pay for trees to be planted, low-energy lightbulbs or stoves in the developing world. it's fine if it actually adds to capacity. The tree planting, it's highly questionable how much good it does. it's really better for a company to ask themselves, how can we reduce our carbon emissions? How does the natural fermentation process in winemaking create one of the most concentrated sources of CO₂ emissions in any industry? The yeast carries out the alcoholic fermentation. So as they do that, they're metabolizing the sugar, creating ethanol, which is alcohol, creating a load of heat and carbon dioxide. The thing about wine is that the emissions that come out of the top of a wine tank are the most concentrated CO2 emissions of any industry at all. Can yeast selection and fermentation techniques make winemaking more sustainable? Yeasts have been selected over years for certain traits, such as particular flavors, producing less compounds such as acetic acid, which we call volatile acidity. At the end of the day, sustainability also includes economic sustainability, so we need to maximize everything that we've grown in the field to get the best possible quality wine.
