Kellogg’s vs Post Raisin Bran: What’s The Difference?

Kellogg’s and Post were not the first cereal manufacturers to make raisin bran. The credit belongs to Skinner who started selling its raisin bran around 1925. They, alone, had the market until 1942 when Kellogg’s and General Foods/Post began to market their own raisin bran cereals.

Skinner sued in the 1940s for the exclusive right to use “Raisin Bran” since they owned the trademark. Unfortunately for Skinner, the judge ruled that the words “raisin bran” were descriptive of the contents of the product and could not be trademarked. This court case opened the door for Kellogg’s, Post, and others to use the words “Raisin Bran” on their boxes.

Today, Kellogg’s and Post now make the most popular raisin bran cereals. Due to their popularity and similarities, people often wonder about the differences between the two.

Kellogg’s vs Post Raisin Bran

Taste Test

Kellogg’s Raisin Bran is the better cereal with raisins. It has more raisins, a good flake size, and the perfect amount of sweetness

Post had fewer raisins which cut down on its sweetness and flavor. Its larger flake size was not preferred to the much more condensed Kellogg’s flakes.

Overall, Post Raisin Bran is not a bad cereal, it’s just a bit inferior to Kellogg’s version. However, we could see how some people might prefer Post Raisin Bran if they like more of a bran flavor with less sweetness.


Kellogg’s Raisin Bran contains nicely sized bran flakes and a healthy portion of raisins.

Post Raisin Bran features larger flakes and fewer raisins.
