5 Common Espresso Mistakes (And How to Fix Them Fast)
5 Common Espresso Mistakes (And How to Fix Them Fast)
Making espresso at home can feel intimidating — but most problems come from just a few simple mistakes. Fix these, and your shots will improve immediately.
Here are the five most common issues and exactly how to correct them.
1. The Grind Is Too Coarse or Too Fine
Grind size controls everything.
-
Too coarse: Sour, weak, fast shot
-
Too fine: Bitter, harsh, slow shot
Fix: Adjust grind slowly — one step at a time — until your shot flows like warm honey.
2. Uneven Distribution Before Tamping
Uneven grounds cause channeling, which leads to inconsistent shots.
Fix:
-
Use a quick WDT (needle tool)
-
Tap and level your grounds
-
Tamp with firm, even pressure
A few seconds of prep makes a huge difference.
3. Not Dialling In Your Ratio
Your brew ratio should be around:
18g in → 36g out in 26–32 seconds
If your shot is too short or too long, adjust the grind and aim for consistency.
4. Using Stale or Old Beans
Old beans = flat flavour, quick blonding, weak crema.
Fix:
-
Use beans roasted within the last 4–6 weeks
-
Keep them in a sealed, cool environment
-
Avoid storing in grinders or hoppers
Fresh coffee is the easiest upgrade.
5. Forgetting That Temperature Matters
Water that’s too hot = bitter
Water that’s too cool = sour
Fix:
Most espresso machines perform best between 92–94°C.
Let your machine warm up fully — 5–10 minutes — before brewing.
Final Thoughts
Espresso isn’t complicated once you understand the fundamentals.
Dial in your grind, level your puck, use fresh beans and aim for a consistent ratio — and you’ll be pulling café-quality shots at home.
