People may be surprised to learn the meaning behind the '57' on Heinz ketchup bottles. They may also not have realised that the number serves a little-known functional purpose.
The popular ketchup - which has more than doubled in price at the supermarket over the past two years - is a staple in most British homes. Many will have noticed that glass bottles are sometimes branded by a signature '57 varieties' label.
But the '57' has much less meaning behind it than many may think. This is because the numbers were randomly selected by Henry Heinz after seeing another business advertising their many varieties of products.
