Where Do Truffles Come From? To inhale the heady aroma of a fresh truffle is an experience like no other. A fresh truffle thinly sliced over your favorite pasta doubles the experience. We are frequently asked why truffles are so expensive. There are several reasons. One is that fresh wild, flavorful and aromatic truffles cannot be commercially cultivated. Another reason is scarcity. Finally, the fresh truffle is a fickle product of nature because each year the truffles might appear in a different place. Only a trained dog with a powerful sense of smell can ferret out these gems of the forest. Fresh truffles also have a very short shelf life. They must be consumed quickly after harvesting. In most cases a week after they are dug up is the time frame. OliveNation guarantees you will receive your truffles in prime condition.
