The Story Behind the “57” on the Heinz Ketchup Bottle

The small “57 Varieties” label on a Heinz ketchup bottle is one of the most recognizable details in everyday branding. While it might look like an ingredient count, a recipe code, or a precise inventory metric, the true origin of the famous number comes down to early advertising strategy and simple intuition.

The Origin of the Number 57

In the late 19th century, Henry J. Heinz was expanding his food company, which was already selling a wide assortment of products including pickles, sauces, and prepared foods.

• The Inspiration: While riding a train in New York City, Heinz saw an advertisement for a shoe company advertising “21 styles.” He was struck by how using a specific number made the product lineup sound varied and distinct.

• The Selection: At the time, Heinz was actually producing more than 60 different items. However, Henry Heinz preferred the sound of 57. He felt the number had a memorable cadence and a pleasant visual symmetry.

• The Strategy: Instead of constantly updating the marketing slogan whenever a new product was launched, he locked in “57 Varieties” as a permanent brand symbol.

The “Tapping the 57” Myth and Glass Bottle Dynamics

Over generations, a household tradition developed around glass Heinz ketchup bottles: tapping the embossed “57” on the glass neck to get the ketchup flowing.

While Heinz eventually embraced this myth in their public relations—noting that the “57” sits right at the sweet spot where tapping creates the ideal vibration—the number was not originally engineered as a physical button.

Why Ketchup Sticks

Ketchup is a non-Newtonian fluid (specifically a thixotropic fluid). This means its viscosity changes depending on force:

1. At Rest: It behaves like a thick gel that stays firmly inside the glass bottle.

2. Under Shear Stress: When tapped or shaken with sufficient force, the internal structure breaks down, allowing it to flow like a liquid.

Tapping the neck or shoulder of the glass bottle creates shockwaves through the fluid column near the neck, breaking the static friction without requiring you to violently smack the base (which often causes a sudden, messy overflow).

Why the Branding Succeeded

While modern squeeze bottles have largely made the glass bottle struggle obsolete, the “57” remains on Heinz packaging globally as an enduring symbol of 19th-century branding.
