You may be familiar with food waste composting, including the materials left over from making alcohol: the pressed wine skins and seeds used in making wine; or the cooked spent grains that are the by-product of making spirits and beer. But you can also compost wine, beer and spirits.

The two most commonly composted alcoholic liquids are wine and beer. Many people believe that the yeasts in both can help really get the compost going. In addition, the liquid in wine and beer (mostly water) helps keep the compost heap moist, which is essential for the necessary composting bacteria to survive.

While you may want to start tossing any leftover bottle of wine or beer, some gardening experts say you should hold back just a little. While some wine and beer will work well on your compost heap, too much alcohol in the liquid can actually kill the bacteria in the compost. These are bacteria that you need to break everything down. So pour one out every now and then for the compost gods. Just don’t go overboard.
