Why Some People Hate IPAs (and the Science Behind It)

India Pale Ales, or IPAs, are one of the most talked-about beer styles in the world. Some people love them. Others can’t stand them.

Why? The answer lies in biology, psychology, and how our taste buds work.

What Makes an IPA Different?

IPAs are known for being hoppy. That means they are packed with compounds from hops, the plant that gives beer its bitterness, floral notes, and citrus-like smell.

Brewers often add extra hops to IPAs to create bold flavors.

But this strong taste is not for everyone. Some people taste intense bitterness. Others smell something like soap or even sweat.

This reaction isn’t random — it’s genetic and chemical.

Bitterness and Biology

The main reason people dislike IPAs is the bitterness. Bitterness comes from compounds called iso-alpha acids in hops.

These are the same types of bitter compounds found in vegetables like Brussels sprouts or kale.

Not everyone tastes bitterness the same way. Scientists have found that our genes influence how we detect bitter flavors.

People with more sensitivity to bitterness are more likely to reject bitter foods and drinks — including IPAs.

Genetics Play a Big Role

A gene called TAS2R38 affects how we taste bitter things. People with a certain version of this gene find bitterness unpleasant. Others with a different version barely notice it.

About 25% of people are what researchers call “super tasters.”

These people are very sensitive to bitter and spicy foods. IPAs often taste too sharp or harsh to them.

Smell Matters Too

Hops don’t just add bitterness. They also change the smell of beer. Some hop varieties give off floral, citrusy, or piney smells. Others produce more earthy, grassy, or even funky aromas.

But not all noses pick up these scents the same way. Some people smell a burst of fruit. Others might smell something closer to body odor.

These differences are due to both genes and past experiences.

Your Brain Adds Context

Your brain also plays a part. If someone’s first IPA tasted bad, their brain stores that memory.

The next time they see an IPA, their brain warns them: “Don’t drink that.” This is called conditioned taste aversion.

It’s common and very powerful.

Also, beer culture plays a role. People who don’t like IPAs may feel left out in a crowd that praises them.

Some might even grow to dislike IPAs more simply because they feel pressure to enjoy them.

Your First IPA Probably Wasn’t Great

Let’s be honest — many people try their first IPA when they’re new to craft beer.

They might grab a double dry-hopped IPA at 7.5% ABV and wonder why it tastes like a pine tree.

That’s not a beginner-friendly beer.

IPAs can be an acquired taste. But starting with extreme versions can turn people off before they get used to it.

It’s Not Just You — It’s Chemistry

In summary, if you hate IPAs, you’re not being picky. Your genes, your senses, and your memories all play a part. It’s not a personal failure. It’s science.

And if you love them? That’s fine too. Just don’t be surprised if your friend makes a face after one sip.

Want to Like IPAs? Try These Tips

If you’re IPA-curious but haven’t enjoyed them yet, try these ideas:

• Start light: Try a session IPA with lower bitterness.
• Look for hazy IPAs: These are often juicier and softer.
• Pair with food: The right meal can balance the bitterness.
• Try different hops: Some hops are fruitier and more pleasant.

But if you never like them? That’s OK. There are many other beer styles out there.

You don’t have to like IPAs to enjoy beer.
