Cilantro: Why Some People Love It and Others Hate It

When it comes to cilantro (Coriandrum sativum), there’s rarely a middle ground: some people adore its fresh, herbal flavor, while others can’t stand even the smell. But did you know this difference may have a genetic explanation?

The “soapy” taste

Scientific studies show that some people carry variants of a gene called OR6A2, which detects molecules called aldehydes. These compounds are found in fresh cilantro — but also in soaps and detergents.As a result, people with this genetic variation often perceive cilantro as tasting like “soap” or “mold,” rejecting the herb entirely.

Genetics + culture

It is estimated that 3% to 15% of the global population experiences this aversion, but the numbers vary by region.In countries where cilantro is widely used (such as India, Mexico, or Brazil’s Northeast), people tend to become more accustomed to the flavor, even if they are genetically predisposed to dislike it.

It’s not just being picky!

Many believe disliking cilantro is “being picky,” but in truth there’s a biological factor involved. Loving or hating cilantro isn’t only about personal taste: your DNA plays a role in this culinary debate.

Leaves vs. seeds: completely different flavors

It’s important to note that cilantro leaves and seeds taste nothing alike:

• The leaves carry the aldehydes responsible for the soapy taste in some people.

• The seeds (often called coriander seeds) have a citrusy, warm, and slightly sweet flavor, with no resemblance to the leaves.

Coriander seeds are widely used in breads, marinades, Indian curries, pickles, digestive teas, and even in liqueurs.So even those who despise the leaves may enjoy the seeds — since genetics doesn’t affect seed flavor in the same way.
