Who We Are

We are not bloggers who Googled “catsup” last week. We are product engineers with over 30 years of hands-on experience inside ketchup and catsup factories. We have formulated recipes, tested viscosity, balanced pH levels, calibrated Brix readings, and stood on production floors watching millions of bottles roll off the line. We breathe catsup — day and night.

That is why Catsup.io exists. We built this site because we know this condiment from the inside out — from the raw tomato paste arriving at the plant to the final squeeze on your plate. Every page on this site is written with the kind of depth that only comes from decades in the industry.

Our Expertise

Over three decades in the condiment industry, our team has:

  • Developed and refined catsup formulations for major production lines
  • Worked as product engineers across multiple ketchup manufacturing facilities
  • Tested hundreds of tomato varieties, vinegar blends, and spice profiles
  • Consulted on quality control, USDA grading standards, and FDA compliance
  • Studied the history, chemistry, and sensory science of catsup from every angle

When we write about catsup ingredients, we are not copying a label — we have mixed those ingredients ourselves. When we review a brand, we know exactly how it was made and why it tastes the way it does. When we share a recipe, it has been tested in our own kitchens and measured against factory standards.

Why “Catsup”?

The spelling catsup is the original American form — older than “ketchup” in US usage and the word that appeared on Heinz bottles before they changed it in the 1880s. We chose it because it is the real name, the heritage name, the one that got pushed aside by marketing but never disappeared. If you grew up calling it catsup, you are in the right place.
