7 Reasons That You’re Getting Wet Puck Espresso – With Fixes

7 Reasons for Wet Puck Espresso - With Solutions 

If you’ve ever had the unfortunate experience of tasting wet puck espresso, then you know how disappointing it can be.

This type of shot is characterized by a watery consistency and weak flavor. 

But no more worries!

Here are some common reasons explained with their solutions. So that you can fix each issue instantly. 

You didn’t tamp the espresso grounds perfectly 

Tamping is the process of pressing down on the coffee grounds in an even manner so that they fit snugly into the portafilter basket. 

If this step is done too forcefully, then too much pressure will be put on the espresso grounds. Which may result in watery extraction from the grounds and a weak shot. 

  • Solution 

To ensure that tamping is done correctly, use a good-quality tamper that fits your portafilter basket.

Make sure to press down the tamper firmly but gently with even pressure across all surfaces of the portafilter basket.

Unequal espresso distribution 

Another reason why are you getting wet puck espresso is, the distribution in the portafilter was not equal.

When you tamp your espresso grounds, make sure that they are evenly distributed across the entire surface area of your portafilter basket.

So that water has an even opportunity to pass through all parts of your coffee grinds during extraction. 

  • A quick solution

To achieve equal distribution, use either your finger or a flat-edged tool to move any loose ground around. Keep doing this until grounds are fully incorporated into your tamped bed of coffee grinds.

Wrong size of the portafilter basket

You’re not using the right size of portafilter basket can also cause the wet puck espresso. Different machines require different-sized baskets for their portafilters.

If you don’t have one that fits yours properly, then chances are good that you will get wet puck espresso as a result.

  • Solution 

Make sure to buy baskets that are designed specifically for your machine model.

Otherwise, there could be gaps between them which could allow excess water flow during extraction. That can lead to over-dilution of your shot and lackluster flavor.

There are Air pockets 

Air pockets in the basket can also cause wet puck espresso. Air pockets in your tamped bed of coffee grinds can lead to under-extraction issues due to uneven distribution of water during extraction. Which can easily cause wet puck shots.

  • Best Solution 

To avoid this issue, make sure to tap down on each side of your tamped bed after packing it properly with an even tamp pressure.

So that any air pockets can escape before brewing begins. This should also help improve overall distribution.

The grind is too coarse

Another reason why your espresso might be coming out wet and soggy could be that the grind of your coffee beans is too coarse.

When the grinds are too coarse, it allows more water to pass through them quickly. 

This causes the bitterness from the coffee grounds to get washed away with the extra water, which may result in a weak-tasting cup of espresso. 

  • Solutions 

To avoid this issue, always make sure to use freshly ground coffee beans that are ground for espresso specifically.

It’s also important to check your burr grinder regularly and adjust it accordingly for optimum performance.

Less amount of espresso grounds

The culprit behind wet puck espresso could also be the number of grounds used in each shot.

If you’re using a few coffee grounds per shot, it’ll result in less flavor extraction and an overall weaker-tasting cup of espresso. 

  • Solution 

To ensure maximum flavor extraction and a strong-tasting cup of espresso, try using 18-20 grams (about 2 tablespoons) of freshly ground coffee beans per shot.

This should produce a nice crema on top once brewed correctly.

Espresso beans are too old to use

Finally, another common problem behind wet puck espresso could be that you’re using old or stale beans that have been sitting around for too long.

As we know old coffee beans begin losing their flavor and aroma as soon as they’re roasted. 

  • Best Solution 

So it’s important to buy freshly roasted beans from reputable sources and use them within 2 weeks of the roasting date for optimal results.

It’s also important to store your beans in an airtight container at room temperature. Try to keep them away from any direct sunlight or heat sources to ensure they stay fresh longer.
