They grow up so fast. Just five years ago, MGP Ingredients (NASDAQ: MGPI) was an obscure company valued at $80 million. Today, it’s valued at over $1 billion — meaning it has become a 17-bagger for a handful of lucky investors. The company’s primary function is to serve as a contract distiller for various whiskey products, including premium brands for Diageo and much smaller craft brands. It doesn’t want fame and glory, which is why most investors have probably never heard of it.
