1927
Postum Foods (later Best Foods) acquired the Hellmann’s brand in 1927. At this time, Hellmann’s was not the only commercial mayo on the market. Out in California, Best Foods had a popular mayonnaise, while Hellmann’s reigned supreme west of the Rocky Mountains. Because Hellmann’s had such a devoted following, Postum Foods decided to keep both brand names. To this day, Best Foods Mayonnaise continues to sell west of the Rockies, while Hellmann’s sells to the east.
