Espresso Beans vs Coffee Beans: 5 Crucial Differences

So you’ve probably noticed, as you stroll the coffee aisle, that you can choose coffee beans or espresso beans. What’s the difference between espresso and coffee beans? Is there even a difference? Let me clarify things for you; the answer is yes and no.

Read on to find out what I mean and when you should buy which type of coffee beans.

The Key Difference Between Making Espresso Vs Coffee

It’s important to start here so everything that follows makes sense. The main difference between coffee and espresso, from a brewing standpoint, is speed. 

It takes more time to make coffee. Whether you’re relying on an immersion method or making drip coffee, it takes at least a few minutes. In comparison, espresso is made very quickly. Thanks to the fine grind and high pressure, extraction occurs in less than 30 seconds.

The brew time difference dictates, to a large extent, the best coffee beans for each method. With that clarification in hand, let’s learn the main differences between espresso beans and coffee beans.

1. The Roast Level

The coffee roast level is the biggest factor determining the flavor, body, and mouthfeel of a coffee. So certain roasts stand out for particular brewing methods.

Are espresso beans just dark roast coffee beans?

This is a common misconception, and it isn’t entirely incorrect. A general rule says that light roasts work best with a slower extraction method, while darker roasts work better with a quick method such as espresso. But where did that rule come from?

It stems right back to the invention of the espresso machine and the birth of authentic espresso culture in Italy (1). Traditionally, espresso was made using dark or medium-dark roasts. 

Dark roasted beans are less dense and more porous due to the longer roasting time (2). That weaker structure allows for complete extraction during a speedy brewing method like espresso. It’s easier for the water to get the flavor compounds out. Using the same parameters with a lightly roasted coffee would lead to underextraction and weak or sour flavors.

Grinder and espresso machine technology has come a long way since 19th century Italy. Advances in burr design and techniques like flow control make it easier to fully extract light roasts in the espresso timeframe. Consequently, we’re seeing more roasters adding lighter roast espresso blends to their rosters. Just look at the growing popularity of Starbucks Blonde Espresso Roast in the last decade!

2. The Roasting Process

The final color of the roast isn’t the only factor influencing bean density and flavor; how the beans are roasted also plays a role. 

Often, espresso beans are roasted slower, using a longer time frame to achieve the same final roast level. Not only does this roast profile reduce bean density, but it also minimizes acidity, a flavor component that is generally more desirable in filter coffee than an espresso drink (3).

3. The Varietal

The two main types of beans are Arabica and Robusta. Arabica is widely considered more premium, known for its sweet, bright, and complex flavors. In contrast, Robusta is earthier, with more bitterness and a heavier body.

The characteristics of Robusta coffee can make it a valuable addition to an espresso blend, bringing the richer mouthfeel and darker flavors we associate with delicious espresso. Robusta beans also yield a denser crema layer when extracted under pressure, something many espresso lovers covet (4). 

Arabica-Robusta blends have long been traditional in southern Italian espresso culture. And major international brand Lavazza still offers many in their line-up for espresso fans.

4. Blends vs Single Origins

You can make espresso with a coffee blend or a single origin, but most espresso coffee beans are blends. Why is that? 

Making espresso requires high pressure, which extracts more flavor from the bean. With an exotic and complex single-origin, this isn’t necessarily a good thing. Flavor notes you enjoy as compelling subtleties in a filter coffee can be overpowering in a cup of espresso.

So, coffee roasters craft espresso blends. The best ones combine different origins and/or varietals, each carefully chosen to balance the others. No one note becomes overwhelming, even in a concentrated espresso shot.

5. The Flavor Profiles

Coffee beans exhibit a huge diversity of flavor profiles, while espresso blends tend to follow the Italian tradition of rich coffee flavor – sweet, smooth, and low acidity. These characteristics are all more prominent in medium or dark roasts. 

Espresso blends of medium roast beans have tasting notes like milk chocolate, nuts, caramel, and ripe fruit. Darker roasted coffee blends are earthier, with notes of dark chocolate, toasted nuts, and molasses. 

It’s rare to find espresso profiles highlighting bright acidic notes or floral flavors. But you’ll find experimental Third Wave roasters offering some far more unusual coffee and espresso beans.

Bonus Difference: Grind Size

This final difference only applies if you aren’t buying whole bean coffee, in which case it is the most important. 

You must buy espresso grind coffee grounds for espresso brewing. If you buy standard ground coffee beans to make espresso, the grind won’t be fine enough to extract in the short brew time. It will taste weak and watery.

The reverse is also true. If you put finely-ground coffee beans into a coffee maker, the brew will be bitter and over-extracted – and might very well clog the filter.

Can you use Regular coffee beans for espresso?

Coffee is a matter of personal taste, so you should use the beans that taste delicious to you. Espresso beans are coffee beans, after all. 

Whether making coffee or espresso, you must dial in the best recipe to suit the beans used. You can definitely use coffee beans for espresso. You may just find it takes a bit more work (or better equipment) to dial in the perfect shot. Likewise, you can brew coffee with an espresso blend; the coffee taste will just be smooth and balanced rather than exciting or complex.

Final Thoughts

I hope I’ve clarified things for you. Espresso beans and regular coffee beans are all just coffee beans. They come from the same coffee plant, and you can brew them however you enjoy, whether that’s with an espresso machine or Aeropress, drip coffee or cold brew. 

A bag of beans labeled as espresso beans is more likely to be a darker roast blend, possibly incorporating Robusta beans. They are easier to extract using an espresso machine and usually deliver a more traditional espresso flavor profile and mouthfeel.
