Why Barista Training Matters 

Before discussing the training techniques, it's essential to understand why teaching your staff how to use a commercial espresso machine is critical for your business's success. 

  • Consistency in Quality: Customers return for the perfect cup of coffee, and a well-trained staff ensures consistency in every pour. 

  • Efficiency: Proper machine operation minimises wasted time and resources, allowing faster service during peak hours. 

  • Machine Longevity: Misuse of equipment can lead to costly repairs. Training your team reduces wear and tear, extending your commercial machine's life. 

  • Customer Satisfaction: Coffee is an experience, not just a beverage. Trained staff can interact with customers confidently, showcasing their skills and elevating the customer's experience. 

  • Brand Reputation: A café known for well-made drinks becomes a community favourite. Barista expertise strengthens your brand. 

With these benefits in mind, let's outline a step-by-step approach to training your staff. 

Step 1: Start with the Basics 

Familiarise your team with the espresso machine's components and functions to build confidence. Understanding how each part works is the foundation for successful operation. 

a. Identify the Key Components 

Introduce staff to the essential parts of the machine: 

  • Portafilter: The removable handle that holds the coffee grounds. 

  • Steam Wand: Used to froth and steam milk. 

  • Group Head: Where water meets coffee grounds for extraction. 

  • Boiler and Water Reservoir: The machine's heating and water systems. 

  • Drip Tray: Collects excess water and spills. 

  • Pressure Gauges and Dials: Indicators for temperature and pressure. 

Explain the role of each component in brewing the beverage in the coffee & espresso machine and steaming milk. 

b. Teach Safety Protocols 

Emphasise safety when handling the machine, especially around hot surfaces and pressurised components. Ensure staff know how to: 

  • Turn the machine on and off safely. 

  • Use steam wands without risking burns. 

  • Manage high-pressure water flow during cleaning. 

Step 2: Espresso Essentials 

Espresso is the core of many coffee drinks. Teaching your staff the art of extraction will elevate their skills and ensure a better customer experience. 

a. Teach the Perfect Espresso Recipe 

Introduce the golden ratio of espresso: 1:2. This means that for every 1 gram of coffee grounds, you extract 2 grams of espresso. For instance: 

  • Dose: 18-20 grams of coffee grounds. 

  • Yield: 36-40 grams of espresso. 

  • Time: 25-30 seconds for extraction. 

Explain how these factors affect the taste and quality of the espresso. 

b. Show Proper Tamping Technique 

Tamping refers to compressing the coffee grounds into a flat, even surface. Demonstrate: 

  • Applying consistent pressure (about 30 pounds). 

  • Achieving an even tamp to avoid uneven water flow (channelling). 

  • Checking that the grounds are levelled. 

Let staff practice tamping until they achieve a smooth, consistent surface. 

c. Guide Through the Extraction Process 

  • Insert the portafilter into the group head securely. 

  • Start the brew cycle and monitor the flow of espresso. 

  • Check for signs of under-extraction (watery, sour taste) or over-extraction (bitter, sluggish flow) and troubleshoot accordingly. 

Streamline operations by dispensing precise portions quickly, reducing the time staff spend on tasks such as serving drinks or condiments. View our Dispenser range here.  

d. Practice, Practice, Practice 

Repetition is key. When you buy commercial coffee & espresso machines online, have staff pull multiple espresso shots, adjusting the dose, grind size, and tamping pressure to understand how each variable impacts flavour and consistency. 

Step 3: Mastering Milk Frothing and Steaming 

The velvety milk texture is essential for lattes, cappuccinos, and flat whites. Teach your staff the science and technique behind steaming milk to perfection. 

a. Explain Milk Science 

Understanding how milk behaves when heated helps staff achieve the desired texture. Cover: 

  • Stretching the Milk: Incorporating air into the milk at the start of steaming to create microfoam. 

  • Texturising: Heating the milk to 60-65°C (140-150°F) ensures silky consistency. 

  • Avoiding Overheating: Milk scorches above 70°C (160°F), resulting in a burnt taste. 

b. Steam Wand Basics 

Train staff to: 

  • Place the steam wand just below the milk's surface to introduce air. 

  • Develop a whirlpool effect by tilting the container at a slight angle. 

  • Stop steaming before the milk gets too hot. 

c. Encourage Hands-On Practice 

After you shop commercial coffee and espresso machines online, let staff froth milk repeatedly using pitchers of different sizes. Challenge them to create foam for lattes (slight microfoam) and cappuccinos (dense, airy foam). 

Step 4: Perfecting the Art of Latte Art 

Latte art combines skill and creativity, enhancing the customer's experience. While advanced designs require practice, even beginners can learn simple patterns. 

a. Start with the Basics 

Teach staff to pour consistent milk texture into espresso shots. Begin with simple designs like: 

  • Heart: A foundation for more complex patterns. 

  • Rosetta: A flowing, leaf-like design. 

  • Tulip: A layered pattern for larger cups. 

b. Focus on Pouring Technique 

Guide staff to: 

  • Start pouring slowly to mix milk with espresso. 

  • Increase speed midway to raise the foam above the crema. 

  • Use precise wrist movements to "draw" the design. 

c. Encourage Experimentation 

Once confident with the basics, let staff experiment with free-pour designs or etching tools to expand their creative range. 

Step 5: Cleaning and Maintenance 

A clean product sourced from commercial espresso machine suppliers & manufacturers ensures better-tasting coffee and extends the life of the equipment. Therefore, maintenance practices should be included as a core part of training. 

a. Daily Cleaning Routine 

Teach staff to: 

  • Backflush the product with the help of a blind filter and cleaning agent. 

  • Clean the steam wand with a wet fabric after each use. 

  • Empty and clean drip trays. 

  • Remove and rinse portafilters. 

b. Weekly Deep Cleaning 

Schedule tasks such as: 

  • Removing and cleaning shower screens. 

  • Soaking portafilters and baskets in a cleaning solution. 

  • Inspecting gaskets and replacing them if necessary. 

c. Troubleshooting Basic Issues 

Equip staff with the knowledge to identify and resolve minor problems, such as: 

  • Blocked steam wands. 

  • Low water pressure. 

  • Uneven extraction. 

Hold and heat large quantities of water, making them ideal for serving numerous people simultaneously in busy environments or during events. Check our Hot Water Urns page.
