Among the various aspects of farm life there are quite a number based upon this type of fermentation We have seen that yeasts are especially related to sugars, and that any product which contains much sugar is more likely to undergo alcoholic fermenta- tion than putrefaction. Yeasts, when dry, may remain alive for a long time and float around in the air. The air at all times and in almost all places is, therefore, sure to contain these living yeast plants, ready to begin to grow and produce a fermentation when- ever they fall into a sugar solution. These air yeasts are some- times called wild yeasts in distinction from the cultivated yeasts that are now articles of commerce. But whether from the air or from a package of commercial yeast, the organisms are essentially the same and their action the same. The chief products of our farms which are liable to direct al- coholic fermentation are the fruit juices. Alcoholic fermentation.
