Your coffee is ground too coarsely, you're not using enough coffee, or you're tamping too lightly.
Here's how to fix it, step by step:
- Adjust your grinder to a slightly finer setting. The grind shouldn't be powdery, but it shouldn't be coarse either.
- Increase the dose of coffee in your filter basket. For the 2-cup basket, aim for 16-19g.
- After you tamp, use the Razor™ tool to trim the puck. If you can't insert the tool because the coffee is too low, you need more coffee.
- Tamp firmly, applying 15–20kg of pressure. Consistency is key.
IF THAT DIDN'T WORK: Check the freshness of your beans. Stale coffee (beans older than 20 days past their roast date) will pour too quickly and taste bitter and watery.
HEADS UP: If the espresso starts flowing in less than 6 seconds, that's a sign of under-extraction. Time your shots.
