The Best Coffee For Espresso Machines


We firmly believe that any coffee roast level (light, medium, or dark) can be brewed any way, as long as you understand how time, temperature, and coffee-to-water ratios impact the final cup.

The above statement certainly holds true for espresso brewing, but with some caveats that we will unpack in our blog below.

This blog aims to help you find the best coffee for espresso, whether you are a straight espresso drinker or one who enjoys espresso with milk. We also point you in the right direction if you are brewing espresso on a super-automatic machine, as the choices with that type of espresso machine are more limited than others (more on that later).

Grab yourself an espresso (or wait until after you read this blog) and learn about the best coffee for espresso brewing!

What is espresso

Espresso as a brewing method

Espresso is a coffee brewing method that involves forcing a small amount of near-boiling water through finely-ground coffee under pressure. The process involves finely grinding coffee into a portafilter basket, tamping it down, and securing it into an espresso machine. The machine then delivers water at an extremely stable temperature and applies 9 bars of pressure to force water through the coffee. The resulting beverage is a liquid espresso that contains soluble solids, soluble gases, and insoluble solids. Soluble solids give the espresso its taste and brew strength, soluble gases provide its aroma, and insoluble solids contribute to its body and mouthfeel, and serve as a barrier to perceived bitterness. A shot of espresso is composed of two layers - crema (light brown, on top) and liquid (dark brown, on the bottom).

Espresso as a coffee choice

All coffee is based on a preference from taste to what color you deem light, medium, or dark roasted coffee. We define espresso-roasted coffee not only by the color but how well that coffee pairs with the espresso brewing method. Espresso does not differ from coffee though consumers sometimes perceive it as different. The only difference between espresso and coffee is that specialty coffee roasters will go out of their way to source and roast coffee to pair well with espresso-based drinks. If you read about our favorite Light Roasted Coffees, you will find that most of these coffees flavor gets lost within milk-based espresso drinks. Most roasters crafting coffee for espresso will push the “development” of that coffee to bring out more of its sugars to help it shine through any addition of milk.

What makes a good coffee for espresso

As mentioned in our intro, any coffee roast level can work for espresso if you are conscious of the brew time, temperature, and recipe. Coffees that are roasted lighter tend to work better at higher water-to-coffee ratios, such as a normale or lungo shot.

All of this changes when you add milk to your espresso beverage.

The spectrum of coffees that work well with espresso shifts as you add milk to your drink. The more milk you add to your drink, the darker or more robust the coffee must be to cut through the milk. Light roasted coffees work exceptionally well as an espresso pulled at a higher ratio (more water) to help improve clarity and reduce acidity. As you start adding milk to lighter-roasted coffees, the milk begins to overpower any underlying taste from that coffee. Due to their development and caramelization, medium to darker roasted coffees can more easily cut through milk where your cappuccino tastes like coffee, not just a large glass of milk.

The key takeaway from the above is that depending on what type of espresso drinker you are will depend on what coffee roast level you should purchase.

Light roast coffee

  1. Lighter roasted coffees work better at higher water-to-coffee ratios like a “normale” or “lungo” shot.
  2. Lighter roasted coffee works great as an espresso, Americano, or smaller milk-based espresso drinks like a macchiato or cortado.

Medium roast coffee

  1. Medium roast coffee is versatile for espresso and works well across many ratios and drink types.
  2. The caramelization of a medium roast will allow it to easily cut through milk but stick to your classic drink sizes and recipes as suggested in our Espresso Drink Calculator.

Dark roast coffee

  1. Some find dark roast too bitter and robust for straight espresso shots, but dark coffee can still work well if brewed much cooler.
  2. Dark-roasted coffee pushes beyond the third stage of development and into carbonization, picking up those classic dark-roasted notes, deep chocolate, and smoky making it a great candidate for larger milk-based espresso drinks. If you like larger milk-based espresso drinks (maybe straying from the classic proportions), then a darker roasted coffee is the way to go.

Watch outs when buying coffee for your espresso machine

Temperature control

If you are in the market for an espresso machine or already have one, make sure you can monitor and alter the brewing temperature.

As mentioned earlier, different roast levels (light, medium, dark) do better at varying temperatures. Lighter-roasted coffees brew and taste best around 203 – 212 degrees Fahrenheit, while medium and darker-roasted coffees do best at or under 203 degrees Fahrenheit. Below is a table of recommended brew temperatures to experiment with different roast types.

The inability to alter brew temperature will limit what coffees work best on your machine, keep an eye out for this feature or understand the limitations of your machine.

Roast Level Recommended Brew Temp (Fahrenheit)

Light Roast

199 - 205

Medium Roast

194 - 200

Dark Roast

188 - 194

Super-automatic espresso machines

If you own a super-automatic espresso machine, your choices for what coffees work best can be limited. We wrote an in-depth article on the topic you can read here, but we will break down what to watch out for if you own one of these machines.

Temperature limitations of super-automatic espresso machines

While super-automatic machines score high on their ease of use and design, they struggle to brew a wide range of coffees due to the lack of temperature control, grind size variability, and a complex internal system that is difficult to clean.

Research shows that most high-end super-automatic espresso machines brew far cooler than most coffee experts recommend, so darker-roasted coffees work best in these machines but watch out for coffee brewed too dark!

Dark oily coffee and super-automatic espresso machines

Dark oily coffee can wreak havoc on the internal system of super-automatic machines due to their oily exterior, which can build up over time, impacting future brews. If you watched the video under the section “How super-automatic espresso machines work,” you will see how the ground coffee passed into a brewing chamber and, once brewed, the puck is pushed out into a waste bin. When using an oily dark roast, the oils will create a film within the brewing chamber which is challenging to remove with the machine’s standard cleaning process. These oils, over time, can become rancid, which impacts subsequent brews in your machine.

The best coffee for milk-based espresso drinks

You’ll find that medium to darker-roasted coffees work best for milk-based espresso drinks due to their deeper development during the roasting process, bringing out caramelization. The increased caramelization helps cut through the milk and maintain the rich coffee taste one would expect. Lighter-roasted coffees lack much of the caramelization in medium and darker-roasted coffees, so they struggle to shine through when using them for milk-based espresso drinks.

We recommend sticking with medium to darker coffees for espresso with milk (even straight espresso) and exploring lighter roasted coffees as espresso with larger water-to-coffee ratios (think lungo or an Americano).

What is the best coffee for espresso shots

The best coffee for espresso depends on what you are looking for from a taste perspective.
Classic and traditional: If you enjoy classic and traditional taste notes, think chocolate and nuttiness, we recommend looking for a medium to darker roasted coffee from Brazil, Mexico, or Peru.
Our Dark Roast, Dark Espresso Roast, or Medium Roast blends are good options here.
Classic but inquisitive: If you enjoy classic coffees but don’t mind a hint of something unexpected, like fruit or floral notes in your cup, we suggest coffees from Ethiopia, Costa Rica, Guatemala, and Honduras.
For those who fall in this category, we typically recommend our Costa Rican coffee, Espresso Roast blend, and Holiday Blend when available!
Modern and adventurous: If you love exploring all of the nuances of coffee from classic to funky and fun and understand how to brew complex coffees,
then we recommend coffees with more florals, fruit, and acidity than the prior bunch. Coffees from Kenya, Ethiopia, Nicaragua, and other high-elevation origins work well here.
Our Kenyan or Ethiopian single-origin coffees are fun to explore with espresso brewing.

What is the best coffee for Americanos

The Americano is quite a forgiving drink due to the addition of water. Those who enjoy light-roasted coffees brewed via drip might find the Americano a suitable alternative to a straight espresso shot. Light-roasted coffees can be tricky as a straight espresso shot. Adding water to the Americano adds clarity and reduces the acidic punch that light-roasted espresso can sometimes have.

Other than light-roasted coffees, both medium and dark-roasted coffees work well as an Americano. Darker-roasted coffees for an Americano will give you more of that “regular coffee” flavor and feel. Since adding water to the espresso shot will dilute the drink, dark roasted coffees will still carry deeper notes of chocolate and nuttiness, which may be what you want with your Americano.
