Jura Professional Coffee Machine: Slow Flow and Dark Crema Explained

Why Is My Jura Coffee Machine Flowing Slowly and Producing Dark Crema?

Are you experiencing slow coffee flow and dark crema while using your Jura professional coffee machine? Don’t worry, you’re not alone! Many coffee enthusiasts face similar challenges. In this blog post, we will explore the reasons behind these problems, specific to Jura professional machines, and offer practical tips and recommendations to help you enjoy the perfect cup of coffee.

Why Does My Coffee Flow So Slowly?

1. Grind Size

A primary reason for slow coffee flow in your Jura professional coffee machine could be related to the grind size. If the coffee grounds are too fine, it will create resistance and slow down the flow of water through the coffee puck.

Solution: Adjust your grinder to a coarser setting using the built-in grinder adjustment feature. Remember that finding the perfect balance between grind size and extraction time is crucial for optimal flavor.

2. Coffee Strength Setting

Jura professional machines allow you to choose the coffee strength setting, which determines the amount of coffee used for each shot. A high coffee strength setting can slow down the flow of water.

Solution: Try reducing the coffee strength setting and observe if it improves the flow rate.

3. Clogged Brew Group

Over time, coffee residue and oils can build up and clog the brew group, causing a slow flow of water through the coffee puck.

Solution: Regularly clean your brew group using the cleaning tablets and instructions provided by Jura. This will help maintain the machine’s performance and prevent blockages.

Why Is My Crema So Dark?

1. Coffee Bean Freshness

The freshness of your coffee beans plays a significant role in the color and texture of your crema. Stale beans can result in dark crema with little aroma and flavor.

Solution: Always use freshly roasted beans and store them in an airtight container, away from direct sunlight and heat sources.

2. Over-extraction

Over-extraction occurs when the water spends too much time in contact with the coffee grounds, leading to a bitter taste and dark crema.

Solution: Adjust your grind size to be coarser, or try reducing the coffee strength setting to allow for a faster extraction time.

3. High Brewing Temperature

A high brewing temperature can cause the coffee to burn, resulting in a dark crema and a bitter taste.

Solution: Jura professional machines typically have a pre-set brewing temperature that is within the recommended range (typically between 195-205°F or 90-96°C). However, if you suspect that your machine’s temperature is too high, contact Jura’s customer support for assistance.

When to Contact the Manufacturer

If you have tried the solutions provided above and are still experiencing issues with slow coffee flow or dark crema, it’s time to contact Jura’s customer support. They can provide further assistance and guidance, as well as help you determine if your machine requires servicing or repairs.
