The grandson of the inventor of Reese’s Peanut Butter Cups has lashed out at The Hershey Co., accusing the candy company of hurting the Reese’s brand by shifting to cheaper ingredients in many products.

Hershey acknowledges some recipe changes but said Wednesday that it was trying to meet consumer demand for innovation. High cocoa prices also have led Hershey and other manufacturers to experiment with using less chocolate in recent years.

Brad Reese, 70, said in a Feb. 14 letter to Hershey’s corporate brand manager that for multiple Reese’s products, the company replaced milk chocolate with compound coatings and peanut butter with peanut creme.

“How does The Hershey Co. continue to position Reese’s as its flagship brand, a symbol of trust, quality and leadership, while quietly replacing the very ingredients (Milk Chocolate + Peanut Butter) that built Reese’s trust in the first place?” Reese wrote in the letter, which he posted on his LinkedIn profile.

He is the grandson of H.B. Reese, who spent two years at Hershey before forming his own candy company in 1919. H.B. Reese invented Reese’s Peanut Butter Cups in 1928; his six sons eventually sold his company to Hershey in 1963.

Hershey said Wednesday that Reese’s Peanut Butter Cups are made the same way they always have been, with milk chocolate and peanut butter that the company makes itself from roasted peanuts and a few other ingredients, including sugar and salt. But some Reese’s ingredients vary, Hershey said.
