Imagine standing at a market on a hot summer day with four watermelons in front of you. They all look fairly similar. They are green, round, striped and roughly the same size. But you are told that only one of them has the visual clues that suggest it is the best choice.
Which one would you pick?
Number 1, 2, 3 or 4?
At first glance, most people will simply choose the watermelon that looks the darkest, largest or most attractive. Others might tap each one and listen carefully to the sound. But there is another simple detail that experienced shoppers often look for — and it can be found underneath the watermelon rather than on top.
Look closely at the four watermelons in the picture.
The best choice in this particular puzzle is Number 1. 🍉
The reason is the large, clearly visible yellow patch on the bottom of the watermelon.
This patch is commonly called the field spot or ground spot. It is the part of the watermelon that rested against the ground while the fruit was growing.
Because that portion was not exposed to direct sunlight in the same way as the rest of the rind, it develops a different color. A creamy, yellow or golden field spot is often considered one useful visual clue when selecting a watermelon.
Number 1 has a particularly noticeable yellow field spot, which is why it stands out from the other choices.
Number 2 has a much paler, almost white-looking area. Number 3 also has a lighter patch that is less pronounced. Number 4 has a yellowish area as well, but its appearance is less uniform and the rind shows additional markings.
However, there is an important point to remember: a yellow field spot is not a guarantee that a watermelon will be perfectly sweet.
There is no single visual trick that can tell you with absolute certainty what the inside of a watermelon will taste like.
The variety of watermelon, growing conditions, harvesting time and storage can all influence the final quality.
Still, the field spot can be a useful clue when you are comparing several watermelons at the store or market.
So why does this patch develop in the first place?
While the watermelon is growing, it rests on the soil. The side touching the ground receives little or no direct sunlight. As the fruit develops, this area remains different in color from the exposed portions of the rind.
Depending on the variety and growing conditions, the field spot may range from pale cream to yellow or even a deeper golden color.
That is why turning the watermelon over and looking underneath can tell you something that you would never notice by simply looking at the top.
Many shoppers make the mistake of choosing a watermelon based entirely on its appearance from above.
They may select the biggest one.
They may choose the darkest green one.
They may look for the brightest stripes.
But size and color alone do not guarantee sweetness.
A very large watermelon can be delicious, but a smaller one can sometimes taste better. Size is influenced by the variety and the conditions in which the fruit was grown.
Instead of relying on just one characteristic, it makes more sense to look for several clues.
One of the easiest is weight.
If you have two watermelons that are approximately the same size, carefully lift both. The one that feels heavier for its size may contain a good amount of water and have a dense, juicy interior.
Again, this is not a guarantee of sweetness. It is simply another clue that can be used alongside the others.
Another traditional method is tapping.
You have probably seen people knock on a watermelon with their knuckles and listen to the sound. Some shoppers believe that a deep, hollow sound indicates a ripe watermelon.
This technique is extremely popular, but it should not be treated as a perfect test. The sound can vary depending on the variety, size, rind thickness and internal structure of the fruit.
So if you like using the tapping method, combine it with other signs instead of relying on sound alone.
The shape of the watermelon can also be worth examining.
A watermelon that has developed relatively evenly often has a balanced, symmetrical appearance. This does not mean that every oddly shaped watermelon is bad. Fruits are natural products, and slight differences in shape are completely normal.
However, if you notice major dents, deep cracks, very soft areas or obvious physical damage, it is worth choosing another fruit.
The rind itself can provide additional information.
Depending on the variety, a mature watermelon may have a somewhat duller appearance rather than an extremely shiny rind. The stripes should be characteristic of the particular variety, but there is no universal color pattern that applies to every watermelon.
This is important because watermelons come in many different varieties.
A characteristic that looks normal on one variety may look completely different on another.
Another detail that some shoppers look at is the stem.
If part of the stem is still attached, its appearance can provide another clue. A dry, brownish stem is sometimes associated with a fruit that has had more time to mature before being harvested, while a greener stem may indicate a more recently harvested fruit.
But once again, this should only be considered one clue rather than a guarantee.
The smartest approach is to combine several observations.
Look at the field spot.
Compare the weight.
Examine the rind.
Check the overall shape.
Look at the stem if one is visible.
Then make your decision.
There is another interesting fact about watermelons that is worth knowing.
