For many, cilantro is a bright, citrusy herb that elevates dishes from around the globe. It’s a staple in salsas, curries, and stir-fries, adding a fresh, vibrant note. But for others, taking a bite of cilantro is like accidentally ingesting a mouthful of soapy water. This stark difference in perception has puzzled food lovers and scientists alike for years. So, Why Does Cilantro Taste Like Soap to some people? The answer lies in our genes.

The Genetic Root of Cilantro Aversion
The soapy taste of cilantro isn’t just a matter of preference; it’s largely determined by genetics. Research has pinpointed a cluster of olfactory receptor genes, which are responsible for our sense of smell, as the key players in this phenomenon. Specifically, a gene called OR6A2 is believed to be the primary culprit. This gene codes for a receptor that is particularly sensitive to aldehydes.
Aldehydes are organic compounds that are found in many plants, including cilantro. They are also notably present in soap. For individuals with a specific variation in the OR6A2 gene, these aldehydes in cilantro bind strongly to their olfactory receptors. This heightened sensitivity leads to the perception of soapy notes, overpowering any other flavors the herb might possess.
This genetic predisposition explains why cilantro can be divisive. It’s not that some people are simply being picky; their bodies are literally wired to perceive cilantro differently. They are not tasting the same herb as someone who enjoys its citrusy flavor.
Is It Just Genetics? Other Factors at Play
While genetics are the primary driver behind the soapy cilantro taste, other genes can also contribute to the complex perception of flavor. Some genes might accentuate the bitter components in cilantro, further intensifying the unpleasant taste for certain individuals. It’s not just one single gene in isolation, but rather a combination of genetic factors that shapes our individual taste experience.
Interestingly, environmental and cultural factors can also play a role, albeit a smaller one compared to genetics. In regions where cilantro is a culinary staple, like Mexico and India, there’s a lower prevalence of the gene variant associated with cilantro aversion. This could suggest a form of natural selection over generations, or simply that those who dislike cilantro in these cultures are less likely to use it in their cooking, leading to a less vocal presence.

The Percentage of “Soapy Cilantro” Population
Studies estimate that between 4% and 14% of the population in the United States find cilantro to taste soapy. Globally, this percentage varies depending on ethnicity and geographic location. Regions with a long history of cilantro consumption tend to have a lower percentage of people with this aversion.
While it might seem like cilantro haters are everywhere, statistically, they are still in the minority. However, those who experience the soapy taste are often quite vocal about their dislike, which can create the impression that the phenomenon is more widespread than it actually is. After all, a single sprig of cilantro can ruin an entire dish for someone sensitive to its soapy aldehydes.
Cilantro Aversion and Supertasters: Is There a Link?
The original article mentioned supertasters, individuals with a higher density of taste buds who experience flavors more intensely. While there’s some overlap, cilantro aversion is not necessarily an indicator of being a supertaster. A supertaster might also dislike cilantro, and their heightened taste sensitivity could amplify the soapy or bitter notes. However, someone who dislikes cilantro might not be a supertaster in general; their aversion could be solely due to the specific genetic predisposition related to aldehyde perception.
Therefore, while you can be both a supertaster and cilantro-averse, like the author of the original article, these are distinct phenomena. Cilantro aversion is primarily linked to olfactory genes, while supertasting is related to taste bud density and broader taste sensitivities.
What Can You Do If Cilantro Tastes Like Soap?
If you’re part of the population that experiences the soapy taste of cilantro, there are a few strategies you can employ:
- Embrace Alternatives: Parsley, mint, or even basil can often serve as excellent substitutes for cilantro in many recipes, offering fresh, herbaceous notes without the soapy undertones.
- Use Coriander Seeds: Interestingly, coriander seeds come from the cilantro plant but don’t carry the same soapy flavor. They offer a warm, citrusy, and earthy flavor profile that can be a great addition to dishes where you want a hint of cilantro-like essence without the fresh leaves.
- Try Cilantro Stems: Some people find that cilantro stems are less soapy than the leaves. Experiment with using finely minced stems in your cooking.
- Build Tolerance (Maybe): While not guaranteed, some suggest that gradual exposure to cilantro might help reduce the perceived soapy taste over time. This is anecdotal and may not work for everyone, especially those with a strong genetic predisposition.
- Cook Cilantro: Heat can sometimes alter the aldehydes in cilantro, potentially reducing the soapy flavor. Adding cilantro to dishes during the cooking process, rather than as a raw garnish, might make it more palatable for some.

The Bottom Line: It’s Not Your Fault, It’s Science!
If cilantro tastes like soap to you, know that you’re not alone, and it’s not just a matter of picky eating. The science is clear: genetics play a significant role in how we perceive this herb. Whether you choose to avoid cilantro altogether or find ways to work around your aversion, understanding the genetic basis of this culinary divide can help you navigate the world of flavor with a bit more insight and perhaps a touch of relief. So next time someone offers you a dish loaded with cilantro, you can confidently (and scientifically) explain, “Sorry, it tastes like soap to me!”
