How should espresso machines be properly maintained for safe use?

• A. By using the same cloth for all components
• B. Color-coding cloths for different parts
• C. Keeping portafilters unseasoned
• D. Not warming up the cups

Answer: (B)

Maintaining espresso machines properly is essential for both safety and quality of the beverages produced. Color-coding cloths for different parts of the espresso machine is a beneficial practice because it helps prevent cross-contamination between components. Different areas of the machine require specific cleaning protocols; for example, using a cloth that has been used to wipe down the steam wand on the coffee contact surfaces can contaminate the coffee. By assigning distinct colors to rags for different tasks—such as one color for the steam wand, another for the drip tray, and yet another for the portafilter—baristas can ensure that they are using the right cloth for the right purpose, thereby maintaining hygiene and ensuring the best flavor profiles in the espresso drinks served. In contrast, using the same cloth for all components can lead to hygiene issues, while keeping portafilters unseasoned and neglecting to warm up cups could detract from the quality of the espresso experience rather than affecting machine safety. Warm cups are important for maintaining the temperature of the espresso, while seasoned portafilters can improve flavor by maintaining the right oil levels.
