What Is Peaberry Coffee?

So, you’re wondering what peaberry coffee is? Maybe you’ve heard of this coffee-anomaly-turned-specialty-drink and you just want to understand what on earth these little coffee jewels are? That’s what I’m here for!

Read on to find out exactly what peaberry coffee is..

Why Is It Called Peaberry?

Coffee beans come from coffee cherries, the bright red fruits of the coffee tree. In each coffee cherry, there is an outer skin – which is how we make cascara – over a layer of pulp, and then typically two seeds covered in a thin layer of parchment.

Here’s a video of a coffee cherry to give you a good visual.

So what is a peaberry coffee bean? It’s a natural mutation in which a single bean grows on its own inside the coffee cherry, rather than with a twin. They lack the familiar flat side that normal beans have, and they are smaller than a standard bean. They are considered some of the best coffee’s in the world.

The Spanish name for this is caracolillo, meaning “little snail,” because of its more rounded shape.

Peaberry is the name applied to the round coffee beans. The development of these round beans has been attributed to the abortion of one of the two ovules in the ovary, thus making extra space available to the single developing seed.

Where Do Peaberries Grow?

It doesn’t matter what region they were grown in, whether they came from an Arabica or Robusta plant, how they were processed or what roasting process is used. Peaberries are simply singleton beans – that’s it.

They’re also more common than you might think. Anywhere from 5% to 10% of coffee cherries contain a peaberry! Coffee labeled “peaberry” means that the peaberries have been picked out during the harvesting process and collected together to sell on their own.

If you keep a sharp eye out, you can occasionally find Peaberries in any bag of beans.

Interestingly, specific regions like Brazil, Tanzania, Kenya, and Kona tend to produce more peaberry since they have the infrastructure in place to find and separate the peaberries from the normal beans.

Can You Trust the Hype? Are Peaberries Better Beans?

When you hear about something like this, you have to wonder, is this genuinely a special product… or is this marketing magic? I mean, if you can market civet poop coffee at $600 a pound (2), you can pretty much market anything, right?

Many coffee lovers claim that peaberry coffee tastes sweeter, lighter, and more flavorful than the regular beans from the same batch. But, the consensus is, while it can be different in its flavor, it’s by no means stable or consistently superior.

Some coffee roasters say that peaberry coffees are easier to roast because their rounder shape lets them roast more easily than their flat-sided cousins. Others claim they’re more difficult for… the same reasons.

Some claim that because a coffee cherry put all of its “juice” into creating one seed instead of two seeds, that seed (AKA bean) may have a different flavor profile. It has yet to be proven that you can count on anything consistently “superior” from one peaberry to the next. But that doesn’t mean it isn’t worth a try! Just don’t go into it expecting anything specific. Let it simply be an adventure for your taste buds!

Are Peaberry Coffee Beans Stronger than Regular Beans?

If you’re talking about caffeine, Peaberry coffee beans do have a slightly higher amount, especially from the Robusta coffee plant. The folks at coffee.org put the caffeine content for Tanzanian Peaberry coffee at 1.42%, while most other coffees tend to come in between 1% and 1.37%. Here’s what Coffee.org has to say about it: (3)

Tanzania Peaberry coffee bean has a 1.42% caffeine content while the Yemen Mocha Mattari has only 1.01% caffeine. Guatemalan and Kona beans are high in caffeine with 1.20 to 1.32% caffeine and Zimbabwe and Ethiopian Harrar having lower levels around 1.10% and 1.13% respectively.

But if you’re talking about stronger flavor, that’s still due to the origin, roast, and extraction. Coffee from Indonesia and East Africa, especially in a darker roast, still tend to taste stronger than coffee from Hawaii or South America, no matter how many beans come from each coffee cherry.

You can find peaberry coffee beans all over the place if you look for them. Particularly since they grow, well, all over the place!

If a coffee shop or online store has a lot of variety, you’re likely to find a peaberry option mixed in.

Kona peaberry is coffee from the island of Hawaii that has been individually hand-sorted to select the peaberries from the ordinary “twin” beans. 

Peaberry beans are not limited to a specific type of coffee bean. They occur in both Arabica and Robusta coffee trees, and can be found in coffee producing regions around the world.
