Genetically-engineered yeast is the future of flavor

Why does grape candy taste so fake? What on earth is blue raspberry, anyway? And what is the difference between natural and artificial, at least when it comes to flavor?
Throughout human history, if you wanted to make a dish taste like strawberry, you had no choice but to add a strawberry. But in the 19th century, scientists began to understand how to synthesize flavor chemicals, whether from plants or from byproducts of coal processing, to evoke familiar flavors. While the technology to evaluate the flavor molecules of a particular food have become increasingly sophisticated in the past century, the basic concept of synthetic flavor has remained unchanged. Until now.
