As with many other foods, there are a number of factors that make a wine "sustainable". Many winemakers and companies now work in a climate-neutral manner. But of course it's not just about CO2 emissions. Sustainable means that cultivation, storage, transport and packaging are carried out in the most resource-efficient and environmentally friendly way possible.
For example, the use of plant protection products and fertilizers has a long-term impact on the environment. Synthetic plant protection products and artificial fertilizers in particular cause particularly high levels of CO2 emissions during production and use. Fungicides are used to combat fungal infestation in wine-growing, for example. The guiding principle here is: "The less, the better."
In addition to cultivation, the packaging of the wine plays a major role in sustainability. The lighter and thinner the bottle, the more environmentally friendly it is. Juice cartons are the best, even if they are still frowned upon in Germany.
Last but not least, you should pay attention to the transport of the wine. If you deliver particularly large quantities and choose a resource-saving shipping company, you will improve the environmental balance. The "last mile" to the winemaker, i.e. the collection on site, is quite crucial, especially if you have to get in the car for that.
