Did you know there are more than 130 species of coffee?

Eyebrows raised? Mine too!

We typically think of coffee in a variety of ways - light, medium, or dark roast, flavored selections, decaf or regular, organic, sustainably grown, pesticide-free, toxin-free, cold brewed, espresso, and on and on.

But, there’s actually a lot more to learn about this bean if we look beyond these basics.
Of those 130 species, there are 4 main types of coffee - Arabica, Robusta, Liberica, and Excelsa.

And, while those names may sound a bit foreign, it’s likely safe to say that most of us, especially if you’re an avid coffee drinker, have at least heard of the Arabica and Robusta varieties as these are the most popular, widely grown, and widely consumed types of coffee beans.

But, what do we really know about these coffee varieties?

When you hear Arabica and Robusta coffee mentioned, do these names spark a touch of curiosity?

What’s the difference between Arabica and Robusta?

Which variety do most folks typically drink? Is Lifeboost Coffee Robusta or Arabica?

Do some coffee varieties taste better than others depending on how you’re enjoying each cup?

Today we’ll be answering each of these questions and more, but to clear up any potential coffee confusion that may have arisen with the above info, let’s do a bit of a comparison…

Personally, I think of these coffee varieties like apples.

Now, I’m sure there are many other fruits which could potentially paint a better picture, but I’m an avid apple sampler, so here goes!

Whether you’re perusing the produce aisles of your local grocery store or walking down row after row of trees in an orchard, it’s abundantly evident that there are many varieties of apples - red and golden delicious, granny smith, gala, Honeycrisp, fuji, pink lady, and on and on.

The thing is, while these are all indeed apples, they each have a slightly different taste, texture, and purpose - as some are best for eating fresh, some are more suited for pies, while others are better in breads, and some make great applesauce, while others are more suited for butters, etc.

Of course, there are a few exotic varieties as well which may be nice to sample just to say you tried a black diamond apple or a Bardsey variety, but these wouldn’t be your daily go-to, or even your occasional treat.

And, this is a great way to think of coffee.

Sure, it’s interesting to think of the fact that there are more than 130 species of coffee.

And its cool to know that those species can be narrowed down to 4 main types of coffee.
But, of those types two stand out as the primary beans grown around the world today, meaning you’ll most often hear about and have the opportunity to sample these varieties, specifically.

So, sit back and enjoy these next moments as we explore the history, differences, quality, taste, and many other details of the two most popular coffee varieties in the world - Arabica and Robusta!

All About Arabica

Most coffee drinkers have at least heard of the name, Arabica.

Why?

Because this is the most common, widely grown, and widely consumed type of coffee in the world.

Arabica coffee is the first type of coffee ever consumed, with some dating its origins as far back as 1000 BC.

During this time, in what is now known as Ethiopia, the Oromo tribe was said to have consumed coffee for the same reason many enjoy this bean today - as a stimulant.

However, the way in which coffee was enjoyed looked a bit different.

In these early days of coffee consumption, the beans were crushed, mixed with fat, then shaped into balls roughly the size of a ping pong ball and eaten.

Hmmm, I can’t decide if this sounds like a good idea for a coffee truffle, or simply something that I’m thankful has gone through some upgrades over time to become what we all know and enjoyably sip (instead of eating) today!

But, I digress…

When this variety of coffee bean made its way from Ethiopia to lower Arabia in the 7th century, this was when/where it was first termed Arabica.

Arabica coffee plants take roughly 7 years to fully mature, and while it can be grown as low as sea level, it grows best at high altitudes.

Within 2-4 years of planting Arabica coffee plants, small, white flowers begin to appear.

These flowers are said to be extremely fragrant, with a scent reminiscent of a jasmine flower.

After careful pruning, coffee berries begin to appear on the plants, and these can be as dark and green as the leaves on the plant before turning yellow, then light red, and finally a deep, glossy red when time to harvest.

Once the berries are ready to harvest, they are called coffee cherries, and of course, after the outer flesh is removed and the inner portion is washed and dried, the coffee bean is revealed.

Most specialty coffees are Arabica with its mild taste, light sweetness, and region-specific flavors setting it apart, elevating this variety as a top contender.

This elegant description of Arabica by Ernesto Illy sums up Arabica quite well - “Arabica is a medium-low wielding, rather delicate tree…that requires a temperate climate and considerable growing care. Coffee made from Arabica beans has an intense, intricate aroma that can be reminiscent of flowers, fruit, honey, chocolate, caramel, or toasted bread.”

Arabica’s distinct flavor, aroma, and sweet mouthfeel are considered to be the biggest reason for this variety’s popularity and preference around the world, but it also is generally considered to be a higher quality coffee as well.

More than 60% of coffee consumed today is Arabica, and yes, this includes your favorite Lifeboost brews!

So then, what about Robusta?

What Is Robusta?

The term robusta is thrown around periodically in the coffee world, but since this variety isn’t as widely available or consumed (compared to Arabica coffee), many aren’t fully familiar with the ins and outs of this brew.

Robusta coffee’s roots “trace back hundreds of thousands of years to the humid, understory evergreen forests in tropical areas of central and western sub-Saharan Africa.”

Today, this variety of coffee is grown in roughly 20 countries around the world, those with warm climates and high humidity, but historically, it has been grown in numerous forms and in regions far beyond its sub-Saharan roots.

The first documented cultivation of Robusta began in the Congo in 1870.

And, since that time, the approximately 20 countries now growing this variety include Uganda, Indonesia, Brazil, and most notably Vietnam, which is the world’s top producer of Robusta coffee.

When Robusta was first grown, it was for quantity rather than quality, so this attribute has certainly stuck with this variety.

But, it only makes sense that quantity took a front seat, as low altitudes, hot and humid climate needs, sun exposure, short maturation rates, and an impressive resistance to disease and pests are marked attributes of Robusta.
These plants can grow up to 32 feet high as a shrub or tree, and they can remain fruitful for 20-30 years.

In some ways it is true that Robusta can be a lower quality coffee, but it does have its perks.

For instance, Robusta coffee is a very resilient type of plant, and this often means conventional growers use fewer chemical pesticides when farming this variety compared to conventionally grown Arabica coffee.

Robusta is also a stronger, more caffeinated coffee, which many connoisseurs prefer.

This variety is commonly used in coffee blends, which has contributed to its not-so-great reputation as blends commonly contain lower quality coffee mixed with high quality coffee to reduce costs.

However, just because it’s Robusta doesn’t mean its inherently poor quality.

Growers are continually improving and now investing in producing a higher quality bean, especially as today’s coffee scene is demanding more.

While Robusta coffee only accounts for 30-40% of the world’s coffee production, coming in second to Arabica, growers are leaning into this variety’s resilience and lower production costs, focusing greatly on improving quality.

When sipping, for those who love a deeper, darker roast, and a fabulous espresso (Robusta is the espresso king, known for producing the best, creamiest, and most stable crema), this variety of bean could surprise you and become your new favorite!

In fact, many espresso blends today already contain Robusta beans.

Apart from espresso, if you’re looking to try Robusta, experts recommend grinding the beans fresh and fine.

Additionally, Robusta requires more intense heat when brewing to bring out the characteristic flavor notes in this variety.

This is another reason why espresso machines and Aeropresses are well suited for brewing Robusta, but a drip brewer isn’t necessarily out of the question.

If the bitter notes of this brew concern you, remember, this is partly due to the greater amounts of chlorogenic acid and caffeine in this variety.

And should that still yield a hard “no” for some, just know that the investments being made today in quality, specialty Robusta coffee could make this variety a real contender, improving on taste and smoothness, moving this bean from a solid 30-40% in global coffee production to a real Arabica rival!

Notable Differences Between Arabica And Robusta Coffee Beans

We’ve covered the history, quality, and a few other specifics related to each of the two most popular types of coffee, Robusta and Arabica.

But, let’s take some time now to explore their differences, looking at several coffee qualities and seeing how these two beans compare.

1- Flavor

Growing regions, conditions, and quality can cause a coffee’s natural flavors to vary greatly, still most categorize Arabica and Robusta coffee flavors as follows:

Arabica coffee is commonly described as naturally having sweet, floral, fruity/berry, or citrusy flavors. It can even present with chocolate or caramel notes.
Robusta coffee is typically described as having more bold, nutty, or chocolate flavor notes while tending to be more earthy, burnt, toasted, or spicy. This variety is also commonly described as having a noticeable dryness.

2- Aroma

Some say unroasted Arabica coffee beans smell like blueberries, or in other words, have a sweet, fruity, or even floral scent.

Robusta (also unroasted), on the other hand, is said to have an aroma similar to raw peanuts.

3- Acidity

Some have described Arabica coffee as being the merlot of coffees, and while many equate this description with the high quality of this variety, it’s also linked to its acidity.

Arabica coffee typically has “bright, wine-like flavors” and this is due to these high levels of acidity.

Robusta coffee is said to “present with lower acidity,” though it has a more “harsh, astringent finish.”

4- Body And Mouthfeel

Arabica coffee tends to have a light to medium body, while Robusta is typically described as having a fuller body and syrupy mouthfeel.

5- Roasting

Since Arabica coffee contains more natural oils and sugars, roasting must accommodate the delicate nature of these beans. This is why you’ll commonly find lighter and medium roasts to preserve the most nuanced flavors in this variety of coffee.

Robusta, however, since it’s naturally more astringent, can tolerate the heat of roasting better than Arabica, which is why this variety is more ideal for darker roasts, including espresso.

6- Caffeine Content

Robusta coffee beans have a more concentrated caffeine content, coming in at 2.7%.

Arabica beans, on the other hand, have only 1.5% caffeine.

7- Chlorogenic Acid, etc.

The taste and health benefits of coffee can be influenced by the chlorogenic acid content of the beans.

Here, Robusta coffee has a chlorogenic acid content of 7-10%, whereas Arabica coffee contains 5.5-8%.

This greater concentration of CGA contributes to Robusta’s classic bitter taste.

Arabica also contains nearly twice the amount of natural sugar than Robusta (no, this doesn’t translate to any sugar in your cup).

And, Arabica coffee contains almost 60% more lipids than Robusta coffee.

8- Appearance

With a keen eye, you can spot a primary difference in the appearance of Robusta and Arabica coffee beans, with Robusta beans tending to have a rounder shape and dry texture while Arabica beans are more oval shaped and oily (depending on roasting profiles).

9- Farming

The Robusta coffee plant is considered to be far more resilient than its Arabica cousin.

Robusta coffee plants can generally be grown at low altitudes, they’re far more pest-resilient, the production costs are typically lower than Arabica, and these plants produce more product per acre (than Arabica).

Compared to Robusta varieties, Arabica are far more delicate, requiring growth at high elevations in cool, subtropical growing climates with a great amount of moisture, a real contrast between sun and shade, and rich soil.

Arabica varieties are also very vulnerable to damage from pests, climate, and handling, which is why (spoiler alert) this coffee is commonly more expensive than Robusta.

10- Quality/Price

Robusta coffee is often the cheaper variety, compared to Arabica. Unfortunately, its price point is generally indicative of quality, taste, and its impact on the environment.

Robusta farmers often use monocropping, and this not only depletes soil and contributes to erosion, but it’s also destroying our rainforests as lands are repeatedly cleared for these crops.
So then, with this information, we know that Arabica does tend to be more expensive, and this variety is generally where to look for specialty coffees.

While conventionally grown Arabica coffee can incorporate some of the same practices listed above for growing Robusta coffee, its need for higher elevations in growing combined with a higher quality bean and higher consumer demand often means you’ll find a greater number of Arabica-focused coffee companies using sustainable farming methods and other environmentally safe practices.

FAQ

1- Is all Robusta coffee low quality?

No.

While Robusta is generally considered lower quality compared to Arabica, its distinct flavor commonly makes this variety of coffee a sought-out winner for some coffee blends, including espresso, as this type of coffee typically yields a better crema.

2- Are all single origin coffees Arabica?

While Arabica coffee is typically the variety you’ll find in specialty coffee, which is commonly single origin to ensure best quality, this doesn't mean there are no single origin Robusta offerings.

In areas where Robusta is widely grown, single origin is available for this variety as well.

3- Which is better, Arabica or Robusta?

Personal preference is king when it comes to coffee (or just about anything, really).

Some folks prefer Robusta, specifically as espresso, for its strong taste and stable, thick crema.

Yet, many people prefer Arabica for its complex flavor profile and generally superior quality.
