What is Backflushing?
Backflushing is the process of running water through the espresso machine in reverse, from the group head towards the reservoir. This helps to dislodge and flush out any residue that may have accumulated in the group head, portafilter, and related components.
Why Backflush an Espresso Machine?
Regular backflushing offers several benefits for your espresso machine, including:
- Improved Coffee Taste: Removing coffee residue prevents it from affecting the flavor of subsequent shots.
- Enhanced Machine Longevity: Backflushing helps prevent clogs and blockages, extending the lifespan of your machine.
- Reduced Cleaning Time: Backflushing regularly minimizes the need for deep cleaning, saving you time and effort.
How Often Should You Backflush?
The frequency of backflushing depends on the usage and type of coffee brewed. Generally, it’s recommended to backflush:
- Daily for commercial espresso machines with heavy usage
- Once a week for home espresso machines with moderate usage
