What does the '57' on Heinz Ketchup bottles mean? My dad used to say something about it, but I just can't remember what! Any ideas? It's been driving me crazy!

The Secret "Sweet Spot" on the Bottle

If you can't remember what your dad said about the number 57, he might not have been talking about the history at all—he might have been talking about how to get the ketchup out of the bottle.

On the classic glass Heinz ketchup bottles, you will notice a raised "57" embossed right into the glass neck, just below the collar.

According to Heinz, that isn't just for branding; it is a functional "sweet spot."

• The Problem: Ketchup is a non-Newtonian fluid (specifically, a thixotropic fluid). It gets thinner and flows better when it's agitated or subjected to force. If you smack the bottom of the bottle, you often just compress the ketchup at the neck, locking it in place.

• The Solution: Instead of hammering the bottom of the bottle, you are supposed to hold the bottle at an angle and firmly tap the embossed "57" on the neck with the palm of your hand.

Applying force right at that exact sweet spot creates just the right amount of vibration to get the ketchup flowing smoothly down the neck and onto your plate.

Henry Heinz’s marketing intuition was so spot-on that "57" became a cultural staple. In 1900, Heinz built New York City’s very first large electric billboard at 23rd Street and Broadway. It was a massive, six-story flashing green pickle that proudly displayed the "57 Varieties" slogan, instantly cementing it in American pop-culture history.

The Mystery Solved

So, the next time you are passing the ketchup, you can confidently solve the mystery. The "57" doesn't represent ingredients, and it wasn't the year the company started. It was simply a lucky number picked by a genius marketer on a train ride—and a secret button designed to save you from exploding a glass bottle all over your
