You buy a bag with espresso on it and the shot still tastes sour. Wondering about espresso beans vs coffee beans? It isn't the plant that differs. Espresso is a way of brewing coffee. “Espresso beans” is what a brand prints on the bag for beans meant for that method. We found no legal definition of that term.
TL;DR
- Espresso beans come from the same plant as regular coffee beans. Espresso is a brewing method, not a type of bean.
- “Espresso” on the bag is the brand's choice. We found no legal definition.
- What you taste depends mostly on roast, grind size and how long your shot runs.
- Regular beans work in an espresso machine if you adjust your grind size and dose.
Are espresso beans different from coffee beans?
Not really: both are coffee beans from the same plant. The difference between espresso beans and coffee beans comes from what the roaster does with them and how you brew. What's printed on the bag mostly tells you what the brand intends. The table shows what each label can and can't tell you.
| What's on the bag | What it does tell you | What it doesn't tell you |
|---|---|---|
| Espresso | The brand's intent | A fixed definition |
| Light, medium or dark roast | How far the brand says the beans are roasted | Whether they work well in your machine |
| A number for intensity | The brand's own scale | A scale that applies everywhere |
| Blend or single origin | A mix or one origin | Whether it's better for espresso |
| Roast date | When the beans were roasted | How the beans taste |
Two bags with espresso on them can be roasted differently. The roast and the roast date say more about the beans than the word espresso does.
For context, here is how common espresso is in the Netherlands. Koffie & Thee Nederland asked 1,153 coffee drinkers online from 24 June to 2 July 2024 and weighted the results. In that survey, 18% drink espresso or double espresso at least occasionally, and 7% of all 1,153 respondents name espresso their favourite (Koffie & Thee Nederland, 2024). The same 2024 survey asked about machines: 29% regularly or (almost) always use a bean-to-cup machine (volautomaat in the survey). A semi-automatic espresso machine is used regularly or (almost) always by 13% (Koffie & Thee Nederland, 2024).
Espresso is a brewing method, not a type of bean
Espresso is a recipe: little water, high pressure and a short brew time. That recipe tells you how to brew and nothing about the type of bean. Our explanation, not research: the cup is so concentrated and the water passes through so briefly that your brewing matters a lot for the taste.
Our explanation, not research: in practice, sour and bitter are the easiest things to pick up in an espresso. Sour is sharp and tart, bitter is dry and flat. You can taste both in a single shot, so they work as clues when you adjust.
Do espresso beans need to be dark roast?
No source we read says it does. You'll often see this in web guides. The table below sets three common claims next to what the sources show and what they leave open. Under the table, we say where the research stops.
| What you often read or hear | What the sources do and don't support |
|---|---|
| Espresso has to be dark roast | In one 2021 study of 8 Arabica coffees, medium roast came closest to the origin cupping profile as espresso (International Journal of Food Science & Technology, 2021). We read the abstract only. |
| Everyone in Europe drinks the same roast | CBI's 2024 market page says northern European consumers traditionally prefer lighter roasts and southern Europeans darker roasts with Robusta (CBI, 2024). |
| Espresso beans are a different bean from regular coffee beans | Same plant; we found no definition that fixes what espresso beans are (see above). |
That doesn't mean medium tastes best: the study brewed each of the 8 coffees at light, medium and dark roast, and covers Arabica only. The CBI line describes what regions prefer, not what tastes best in your cup.
Where does the research stop? We found four gaps. There is no definition of espresso beans from CBI, the Specialty Coffee Association (SCA) or EU rules. There is no fixed strength standard for espresso. We also found no full-text espresso study linking roast to how much of the coffee ends up in your cup. Nor did we find a source that calls a blend or single origin better. For what roast does to taste, acidity and caffeine, read our light vs dark roast comparison.
What does grind size do to your shot?
More of the finest dust slowed the water's flow, and shot time followed. In a 2024 Scientific Reports study, extraction was 17 to 18% in fast shots of up to 15 seconds. It was 19 to 20% in the best-scoring shots of about 30 seconds, from one Costa Rican Arabica on one machine (Scientific Reports, 2024).
The scores came from an experienced taster's informal scoring, not a blind panel. Treat the numbers as a starting point for your own shots and keep track of your shot time, so you can compare.
Arabica or Robusta for espresso
A 2019 Food Research International study (abstract only): Robusta gave larger crema volume, Arabica more stable crema (Food Research International, 2019). A 2024 Foods trial found no significant day-0 body difference: 100% Arabica 5.98, an 80/20 Arabica/Robusta blend 6.04 (Foods, 2024). The panel was trained, the machine bean-to-cup, roast and origin unstated; see our Arabica vs Robusta comparison.
What do you do when your shot tastes off?
Our rule of thumb, not research: you can usually taste what's going wrong in your shot. Sour and thin usually points to water running through too fast. Bitter and dull usually means it ran through too slowly. Change one thing per shot, so you can see what worked and what didn't.
| Symptom | Cause | What to change first |
|---|---|---|
| Sour and thin | Grind too coarse | Grind one step finer |
| Bitter and dull | Grind too fine | Grind one step coarser |
| Gushes out | Too little coffee in the portafilter | Dose a bit more |
| Barely drips through | Too much coffee in the portafilter | Dose a bit less |
| Little or no crema | Old beans | Look at the roast date |
If your shot tastes sour and thin, grind size is the first suspect. If it gushes out without tasting sour, look at your dose first. After each shot, note your setting and shot time, for example on your phone. After a few shots you'll see a pattern.
On crema we have one source: the study from the previous section. In that 2019 Food Research International study, bean variety and freshness mainly set the crema volume (Food Research International, 2019). It says nothing about body or taste.
Can you use regular coffee beans for espresso?
Yes, you can. An espresso machine doesn't know the label; it pushes water through whatever you put in. Adjust your grind size and dose and use beans that are still fresh, and regular coffee beans can work well in your espresso machine. Expect to adjust your settings again, though.
A different bag can change your shot time, and then last week's grind setting may no longer work. Use the table above as a starting point. Start small: take one bag from our coffee beans and pull shots with it for a week, so you can tell whether it suits your machine and your taste.
Two situations have their own guide. If you mostly drink espresso with milk, read our guide to coffee beans for cappuccino. If you brew with a bean-to-cup machine, see our guide to the best coffee beans for a bean-to-cup machine.
How to choose beans for espresso
Read the bag as a hint, not a guarantee. Look at the roast date, the roast and what the brand says about the taste. A number for strength or intensity is the brand's own scale, so don't compare it across brands. You'll find more general tips in our guide to choosing coffee beans.
A recent roast date is a better sign than a bag with no date. If there's no date, you can ask when the beans were roasted. Treat the roast as a pointer to the taste and see for yourself what suits you. CBI's 2024 market page says northern European consumers traditionally prefer lighter roasts, so what sells well in one region says little about your cup (CBI, 2024). Whether you pick a blend or a single origin comes down to taste.
Frequently Asked Questions
What are espresso beans, and how are they different from coffee beans?
“Espresso beans” is a label a brand puts on the bag for beans meant for espresso. They are ordinary coffee beans from the same plant; any gap comes from the roast and the brewing. We found no legal definition of the term. Roast and roast date tell you more about the beans than that one word.
Can you use espresso beans to make regular coffee?
Yes. They're coffee beans, so you can use them for filter coffee or a French press. Grind coarser than you would for espresso. Then taste the cup and adjust the grind from there.
Can you use regular coffee beans in an espresso machine?
Yes, a machine doesn't care which beans you use. Grind fine enough, use the same amount of coffee every time and taste your shot. With a new bag, you'll often need a different grind size than for the last bag.
Is dark roast better for espresso?
That depends on your taste and how you brew; try a lighter and a darker roast side by side. In one 2021 study of 8 Arabica coffees, medium roast came closest to the cupping profile from the origin countries as espresso (abstract only). Our light vs dark roast comparison goes deeper on taste, acidity and caffeine.
What grind size is best for espresso?
There's no fixed setting: it depends on your beans, grinder and machine. Use your shot time as a guide. If it runs too fast, grind finer; if it runs too slow, grind coarser. Then taste again. In one 2024 Scientific Reports study, the best-scoring shots ran about 30 seconds, but that was one Arabica on one machine.
Which is better for espresso, Arabica or Robusta?
There's no general answer. In one 2024 study, a trained sensory panel found no significant difference in body on day 0 between 100% Arabica (5.98) and an 80/20 Arabica/Robusta blend (6.04). That was espresso from a bean-to-cup machine at 19 bar and 20 grams, with roast and origin not stated. For more, read our Arabica vs Robusta comparison.
Start with one bag and change one thing per shot
Pick one bag, note the roast date and pull a few shots. Change one thing at a time, so you can see what works. Your own shots will show how the beans work in your machine and with your grinder, and whether you like the taste. See our coffee beans →
