Fermenting Fruit and Animals

Every year a certain amount of fruit falls from our trees and ends up rotting on the ground. For some people, that would be the end of the story. A few others might clean up the resulting mess. However, we choose to leave it in place. The fruit actually ferments and produces alcohol. Even through many people don’t realize it, fermentation is a natural process that would happen quite easily without anyone’s help. In fact, some of the best tasting foods, such as sauerkraut, are naturally fermented (most sauerkraut you buy in the store isn’t naturally fermented and you’d be able to taste the different readily if it were).

It turns out that the animals in the area enjoy imbibing in a little fermented fruit. Our experience isn’t uncommon either—it happens all over the world. There is never enough fruit left over to make the animals terribly drunk (as happened recently to a moose in Sweden). Most of the time they appear to get a bit happy and go on their way. Until the other day, all I had ever seen eating the fruit were the rabbits and deer in the area. So, it surprised me a little to see our laying hens swaying back and forth on their way to the coop. It seems that they also enjoyed the fermented pears lying on the ground.

All of the fruit we grow (apples, pears, plums, cherries, and grapes) will ferment given time. You might wonder how the fermentation takes place. The easiest way to see the start of fermentation is to look at unwashed grapes, especially wild grapes. If you look carefully, it appears that they’re covered with dust. That’s not actually dust, it’s wild yeast. When the fruit is ripe enough and the yeast is able to breach the skin, fermentation begins.

If it’s so easy to create alcohol from natural sources, you might wonder what all the hubbub is about in buying yeast. Different yeast have different properties. When you rely on a wild yeast, you get varying results. Cultured yeast has known properties, so it works better when making bread or wine. The results are repeatable. In addition, using a cultured yeast makes it easier to stop the natural conclusion of the fermentation process, which is always some type of vinegar-like substance (more specifically, lactic acid).

At issue here is how much responsibility a landowner has to nature when it comes to fermented fruit. Because we pick the vast majority of our fruit, the animals in our area get a little happy and that’s about the extent of what happens. When you leave full trees of fruit to rot though, it could become a problem for the wildlife in your area, such as that moose in Sweden. If you can’t pick your fruit for whatever reason, try to find someone who will. Otherwise, you might find yourself trying to correct the errant judgements made by the wildlife in your area when it gets drunk.
