Some people pronounce the candy “Rees-EES” while others pronounce it “Rees-IS.” A little history behind the beloved chocolate peanut butter cup will provide you with the answer. Since Reese's is named after the man Harry Burnett Reese. H.B. Reese himself, the correct pronunciation is in fact “Rees-IS.”

Why does Reese's have an apostrophe?

Reese's Peanut Butter Cups were named after their founder, Harry Burnett Reese, so it's a possessive form of his last name. It'd be the same as if you were talking about Reese Witherspoon's movie: You'd say “Reese's movie.”

Why do they say not sorry Reese's?

We know it's really easy to make people want a Reese's… you can basically show someone a cup and boom, they'll crave a peanut butter cup (this is fact). So we launched with a new tagline and mantra: “Not Sorry.” An self-aware, acknowledgement that we're not sorry that we're about to make you want a Reese's.
