5 Common Espresso Mistakes (And How to Fix Them)

Even the best espresso machine can’t save you from a bad shot if your technique is off. Whether you’re just getting started or troubleshooting your setup, knowing what you’re doing wrong is half the battle. Here are the top 5 espresso mistakes—and exactly how to fix them.

1. Using Pre-Ground Coffee

The Problem: Pre-ground coffee loses flavor fast and lacks consistency.

The Fix: Use a burr grinder to grind fresh beans just before brewing. Shop high-quality coffee grinders [link to grinder collection].

2. Incorrect Grind Size

The Problem: Too fine = bitter; too coarse = weak and watery.

The Fix: Adjust your grinder settings. Aim for a consistency similar to table salt for espresso.

3. Poor Tamping Technique

The Problem: Uneven tamping leads to channeling, where water flows through one spot and ruins extraction.

The Fix: Tamp evenly with 30 pounds of pressure. A good tamper makes a big difference.

4. Bad Water Quality

The Problem: Tap water can introduce unwanted minerals and flavors.

The Fix: Use filtered water or invest in a water softener for your espresso machine.

5. Wrong Brew Temperature

The Problem: If the water is too hot or too cold, it will affect extraction.

The Fix: Make sure your machine heats to around 195–205°F (90–96°C). Many premium machines do this automatically.

Conclusion:

Mastering espresso takes practice—but avoiding these common mistakes will dramatically improve your results. We’re here to help you make the perfect cup, every time.
