Renowned for its super-strong coffee flavour and energy-boosting potential, espresso is perfect for sipping on its own. But it’s also the critical ingredient to all the famous and popular coffee drinks, like a cappuccino or a macchiato. A well-brewed espresso in the office offers a moment of consistency, care and connection in an otherwise demanding day.
Yet many offices invest in a premium espresso machine only to discover that no one truly knows how to use the espresso machine correctly. Buttons get pushed at random, shots run too long or too short, the grind size remains unchanged for months, and the result is a bitter, watery or inconsistent brew. When you understand your machine, the coffee products it uses, and the technique behind each step, espresso becomes easier, faster and significantly better.
The team at Corporate Coffee is dedicated to delivering the coffee goods – machines, products, beans, and even resources on all things coffee! In this step-by-step guide, we break the entire process down, from understanding your equipment to pulling your first perfect shot. Let’s dive in.
Understanding Your Espresso Machine
So, how do I make espresso at home or in the office? Well, first you need to understand what you’re working with. Most South African offices use one of two types of coffee machine systems: semi-automatic or fully automatic coffee machines. Fully automatics are popular in corporate spaces because staff simply select a drink, and the internal system handles dosing, tamping, extracting and cleaning, so they’re a go-to when choosing a coffee machine. Semi-automatics, on the other hand, give users more control, ideal for offices with designated coffee champions or on-site baristas.
Regardless of type, every espresso machine relies on the same core components. The boiler or thermoblock heats the water to around 90 to 96°C, the sweet spot for extraction. The portafilter holds your ground coffee, locking into the group head where hot water meets the compacted puck. The pump, often generating a pressure of nine bars, forces water through the grounds to create espresso. Most machines also include a steam wand for frothing milk, a drip tray for catching excess liquid and a built-in or external grinder for preparing fresh coffee beans.
Preparing with the Basics of Brewing
Espresso is unforgiving. It captures every detail of both the bean and technique, which is why preparation makes all the difference. Start with fresh coffee beans. In South Africa’s office environments, where beans often sit in airtight containers for too long, freshness is the first element that changes the outcome.
Grinding is equally critical. For espresso, you need a fine, consistent grind. Too coarse, and the water flows through too quickly, resulting in a sour, weak shot. Too fine, and the machine struggles to push water through, leading to a bitter, burnt taste. Beginners often ask how to use an espresso machine without constantly adjusting the grinder, but the reality is that minor tweaks are part of the craft, especially as beans age or humidity levels change.
Water quality affects flavour as much as grind size. Using filtered water prevents scale buildup, improves extraction and prolongs the lifespan of your corporate espresso machine. Temperature is typically automated, but machines operating between 90°C and 95°C produce the best balance of flavour extraction without burning the grounds.
Your Step-by-step Guide for How to Use an Espresso Machine Properly
Using an espresso machine in a corporate setting doesn’t have to be intimidating; the trick is to learn the steps before you put them into motion. So what is the correct way to use an espresso machine? Follow these steps to pull the perfect shot every time and make the most of your office espresso setup. If you’re more of a visual learner, the images below can guide you through the steps to making coffee.
Step 1: Flush the Grouphead
Before brewing, flush hot water through the grouphead to remove leftover coffee grounds and stabilise the temperature, like in the image below. This ensures each shot starts with a clean, consistent flow.
Step 2: Fill the Portafilter with Freshly Ground Coffee
Grind fresh coffee beans to a fine, sand-like texture with the coffee bean grinder. If you have scales, measure the right dose (usually 18 to 20g for a double shot) and fill the portafilter evenly. Correct dosing is crucial for a delicious flavour balance.
Step 3: Distribute the Coffee Evenly
Use a distribution tool or your finger to level the coffee in the basket. Even distribution prevents water from creating channels and ensures proper extraction.
Step 4: Tamp the Coffee Firmly
Press down the coffee with a tamper using steady pressure (around 15 to 20 kg). Keep the surface flat and smooth. Proper tamping is another key element to coffee making because uniform extraction will deliver better brews.
Step 5: Lock the Portafilter into the Grouphead
Insert and twist the portafilter securely into the machine’s grouphead. Make sure it’s properly seated to avoid leaks or uneven pressure during extraction.
Step 6: Pull the Shot
Start the machine and extract the espresso by pressing the appropriate button. For a double shot, click the button with two-cups or the one-cup button for a single shot. It should take around 25 to 30 seconds for a double shot, producing about 36 to 40ml of espresso with a rich, golden crema. Adjust grind size or dose if the flow is too fast or too slow.
If You’re Making Milk Coffee, Continue with the Steps Below:
Step 7: Purge the Steam Wand
Before frothing milk, release a short burst of steam to clear condensation by twisting the wand handle. This prevents water from entering your milk and ensures smooth microfoam. You can cover the tip of the wand with a towel to avoid burning yourself and making a mess, too.
Step 8: Froth the Milk
For cappuccinos, flat whites, macchiatos or lattes, insert the steam wand just below the surface of cold milk. Raise and lower the milk jug slightly and swirl the milk to create microfoam. You want to heat the milk to approximately 60 to 65°C and then pour immediately after frothing.
Step 9: Serve and Enjoy
Serve your espresso shot or milk-based drink immediately. Freshly pulled espresso delivers the best aroma, flavour and crema. When pouring, have some fun with it, and try your hand at some latte art by varying how you pour the milk.
Step 10: Clean as You Go
After each shot, rinse the portafilter, wipe the steam wand and flush the grouphead. Maintaining cleanliness during brewing ensures consistently great coffee in a busy corporate environment, so make sure you read up on how to clean a coffee machine.
Common Mistakes to Keep in Mind (and How to Avoid Them)
Even well-equipped large office kitchens often struggle with consistency because mistakes creep in unnoticed. One little but frequent issue is using stale beans that have oxidised, resulting in flat or overly bitter espresso. Another is failing to adjust the grind size, which is a problem intensified in offices where multiple people use the same grinder.
Rushing the tamp or tamping at an angle creates uneven pressure, which ruins extraction. Another common coffee machine problem comes from people forgetting to flush the group head, leaving old coffee oils behind, affecting both flavour and machine hygiene. Many beginners also overfill the portafilter, preventing it from locking in properly and damaging the group head over time. Finally, be careful not to let a shot run far too long in the hopes of making a stronger coffee, when in reality it creates bitter, over-extracted espresso.
Wave Goodbye to Cups that Don’t Make the Cut
An espresso machine is a powerful tool in any South African corporate environment. Think: morales boosted, productivity remains solid and rituals are made as your team makes their morning cups over a chat. When you know how to use an espresso machine correctly, every shot becomes consistent and satisfying, whether you’re an experienced coffee drinker or a complete beginner.
