Espresso Explained: Great Espresso Starts Long Before the Machine

Espresso Explained: Great Espresso Starts Long Before the Machine

There’s something special about espresso.

The aroma. The rich body. The layer of golden crema sitting on top. And, of course, that concentrated burst of flavor packed into a tiny cup.

But espresso may also be one of the most misunderstood drinks in the coffee world.

One of the biggest misconceptions?

There is no such thing as an “espresso bean.”

That’s right. Espresso isn’t a particular type of coffee bean. It’s a method of brewing coffee. And understanding that is the perfect place to start if you want to make truly great espresso.

So, What Exactly Is Espresso?

Espresso is coffee brewed by forcing hot water under pressure through a compact bed of finely ground coffee.

Unlike drip coffee, where gravity slowly pulls water through the grounds, an espresso machine uses pressure to produce a small, concentrated beverage in a relatively short amount of time.

A modern espresso recipe might use roughly 18 grams of ground coffee to produce about 36 grams of espresso in approximately 25–30 seconds. But those numbers aren't laws. Different coffees, grinders, machines, baskets, and flavor preferences can call for different recipes.

The goal isn't to hit a magic number.

The goal is to produce a balanced espresso that tastes great.

There Is No Such Thing as an Espresso Coffee Bean

Walk through a grocery store and you'll probably see bags labeled “Espresso Beans” or “Espresso Roast.”

That can make it sound like espresso grows on a special espresso plant.

It doesn't.

The same coffee beans used for drip coffee, pour-over, French press, cold brew, and other brewing methods can also be used to make espresso.

Coffee generally comes from species such as Coffea arabica and Coffea canephora, commonly called Arabica and Robusta. Within those species are numerous varieties, origins, processing methods, and flavor profiles.

Espresso describes how the coffee is brewed—not what the bean is.

When a roaster labels a coffee an "espresso roast" or "espresso blend," they're usually saying they selected and roasted that coffee with espresso preparation in mind.

Traditionally, espresso blends were often roasted darker, but modern espresso can range considerably in roast level.

You can make espresso from a light roast.

You can make espresso from a medium roast.

You can make espresso from a dark roast.

You can use a blend or a single-origin coffee.

What matters is how the coffee, roast, grind, dose, machine, water, pressure, temperature, and extraction work together.

Where Did Espresso Come From?

The story of espresso begins in Italy around the turn of the 20th century.

Coffee shops had a problem: brewing individual cups of coffee took time.

Inventors began developing machines that could use steam and pressure to prepare coffee much faster.

In 1901, Luigi Bezzera of Milan patented improvements to machinery designed to rapidly prepare individual servings of coffee. His design helped establish important concepts that would eventually lead to modern espresso machines.

A few years later, Desiderio Pavoni acquired Bezzera's patent and began commercially producing machines, helping bring this new style of coffee preparation into Italian cafés.

Those early machines, however, weren't producing exactly the espresso we recognize today.

Another major breakthrough came decades later.

In 1947, Achille Gaggia patented a lever-operated system that used substantially greater pressure than the older steam-driven machines. This helped produce the concentrated espresso topped with the characteristic layer we now call crema.

Espresso continued evolving, and pump-driven machines eventually became common.

So rather than crediting espresso to one single inventor, it's more accurate to view modern espresso as the result of several important Italian innovations—with Bezzera, Pavoni, and Gaggia playing especially significant roles.

What Does “Espresso” Mean?

The Italian word espresso is closely associated with the idea of something being prepared expressly or specifically for the customer, while also becoming connected with the rapid preparation of coffee.

That idea remains part of espresso culture today.

An espresso isn't supposed to sit around.

It's prepared individually and enjoyed fresh.

And at Flyway Brew Co., freshness is something we take seriously.

Great Espresso Starts With Fresh Coffee

You can own an expensive espresso machine and still make disappointing espresso.

Why?

Because the machine can't restore flavors and aromas that have already disappeared from stale coffee.

Roasting creates an enormous number of aromatic compounds. Once roasted coffee is exposed to oxygen, those aromas and flavors begin changing.

That's why the age and storage of your coffee matter.

Great equipment can't make stale coffee fresh again.

At Flyway Brew Co., our focus on freshly roasted coffee isn't just a marketing phrase. Freshness can make a noticeable difference in aroma, flavor, and the espresso-making experience.

The Grinder May Be More Important Than You Think

If you're building a home espresso setup, don't spend your entire budget on the espresso machine and then treat the grinder as an afterthought.

Espresso is extremely sensitive to grind size.

Too coarse, and water can move through the coffee too quickly. The result may taste thin, sour, weak, or under-extracted.

Too fine, and water may struggle to move through the coffee bed. The espresso can become harsh, bitter, dry, or over-extracted.

Small grinder adjustments can make surprisingly large differences.

A quality burr grinder designed for espresso gives you the fine adjustment necessary to dial in your shot.

Dose, Yield and Time

If you want to become better at espresso, start measuring what you're doing.

Three useful numbers are:

Dose: How much dry ground coffee goes into the portafilter.

Yield: How much liquid espresso comes out, preferably measured by weight.

Time: How long the extraction takes.

A useful starting recipe might look something like:

18 grams coffee in → 36 grams espresso out → approximately 25–30 seconds

That's roughly a 1:2 brew ratio.

But remember: it's a starting point, not a commandment.

Taste the espresso.

If changing the grind or ratio makes the coffee sweeter, more balanced, and more enjoyable, that's more important than blindly following a stopwatch.

Distribution and Tamping Matter

Once you've ground your coffee into the portafilter, you want the grounds distributed as evenly as possible.

Why?

Water follows the easiest path.

If one section of the coffee bed is much less dense than another, water can rush through that area. This is commonly called channeling, and it can result in an uneven extraction.

After distributing the grounds, tamp them evenly to create a level, consistent coffee bed.

You don't need to prove your strength to the portafilter.

Consistency and a level tamp matter more than trying to tamp as hard as humanly possible.

Water Matters Too

Your espresso is mostly water, so water quality has an enormous effect on the finished cup.

Water that's excessively hard, excessively soft, or chemically unpleasant can change flavor and may also affect your espresso machine.

Good espresso water should have an appropriate mineral balance—not simply be completely mineral-free.

That's one reason two people can use the same coffee and similar equipment yet produce espresso that tastes noticeably different.

Temperature and Pressure

Modern espresso is commonly brewed with water somewhere around 195–205°F (90–96°C), although the ideal temperature depends on the coffee and roast.

Espresso is also commonly associated with approximately 9 bars of brewing pressure.

Again, these are useful reference points rather than universal rules.

Coffee is agricultural. Different coffees behave differently.

That's part of what makes espresso so interesting.

What Is Crema?

That beautiful golden-brown foam sitting on top of a freshly pulled espresso is called crema.

Crema forms partly because pressurized brewing traps gases—particularly carbon dioxide—within the beverage. As espresso exits the pressurized environment of the machine, gases come out of solution and contribute to the foam on the surface.

Freshly roasted coffee can contain considerable carbon dioxide, which is one reason coffee freshness and resting time can affect espresso behavior.

But here's another misconception worth clearing up:

More crema doesn't automatically mean better espresso.

Crema can tell you something about the coffee and extraction, but the final judge should always be taste.

What Should Good Espresso Taste Like?

Great espresso shouldn't simply taste "strong."

It should be concentrated but balanced.

Depending on the coffee, you might experience flavors reminiscent of chocolate, caramel, nuts, berries, citrus, stone fruit, spices, or countless other characteristics.

A well-prepared espresso can have sweetness, pleasant acidity, controlled bitterness, a rich mouthfeel, and a long finish.

If your espresso is extremely sour, bitter, watery, or unpleasantly harsh, don't immediately blame the beans.

Try adjusting your grind, dose, yield, temperature, or extraction time.

That's called dialing in espresso—and it's part science, part craftsmanship, and part tasting.
