Some candies in the world are considered the sourest candy. Every time you try one of the sourest candies, you feel like it’s the first time.

Each sour candy brand is different from the other, yet all have the tartness and mouth-puckering taste that candy lovers enjoy. You might wonder what candy is the most sour in the world, but it can’t be the same for all. Some would find one candy more sour than the other.

Ranked: What Candy Is the Most Sour in the World?

#5 Sour Flush

Sour Flush candy is weirdly shaped like a toilet plunger. You dip the lollipop into the plastic toilet filled with acidic powder or sour sugar. The concept is appalling, but the packaging keeps your mind away from toilet thoughts. With neon colors representing flavors such as watermelon, raspberry, and green apple, Sour Flush is one of the sourest candies in the world.

It’s better than most sour candies, but not the best. The sourness does not last long, and we should not forget that the toilet shape does make you think twice before you plunge into the neon toilets. If you are still intrigued, try the blue raspberry flavor—it’s the sourest of all Sour Flush flavors.

What Was the First Sour Candy?

The initial production of sour candies started in the 19th century, but most people were unsure about consuming the tart treats, so the first ever sour candy is unknown. However, Atomic Fireballs by Ferrara Pan Candy Company is the most popular first sour candy. It came out in 1954.

Is Sour Candy Good for You?

If a sour candy has a mild sour taste and a little sugar to go with it, the candy won’t harm your teeth or your health. Candies with extreme acidic flavors mixed with a high amount of sugar (like the ones in this article) are incredibly harmful for you if consumed regularly.
