Reasons And How To Prevent Coffee Grounds In Coffee?

1. Coffee is being ground too fine. 

Most coffee makers come with a filter or strainer that captures the ground coffee. This prevents any of these grounds from making it into your final product. When the hole size in your coffee strainer/filter is larger than the finely grounds, they will go through.

If the coffee is very finely ground, a dense lump may be formed

If your coffee is very finely ground (such as for espresso), it may form one dense lump. This causes a build-up of water that will pool and overflow. When the water overflow, it will contain coffee grounds that end up in your carafe.

SOLVE: Don’t use a too fine grind. Look for coffee that has been specially ground for your coffee grinders methods, if you’re grinding your own coffee beans, know exactly the level of grinding coffee.

When using drip coffee makers, using plastic or metal filters without paper, sometimes fine coffee grounds can still pass through. However, there usually aren’t so many that they make drinking the coffee unpleasant. If this situation bothers you, add a paper filter.

2. Problems with paper filters.

When you add a paper filter to your coffee maker, it sometimes does not stick to the walls of the basket. If you are brewing your coffee with a grind that is too fine or using more than enough coffee, this will cause a build-up of water that overflows into the gap between the paper filter and the filter basket. This causes a lot of ground coffee to bypass as there is absolutely no filtration from the filter basket, resulting in a very muddy cup of coffee.

Paper filters also have the potential to collapse under pressure, leading to an overflow that will include coffee grounds into your cup of joe.

SOLVE: The trick is to pre-wet the filter inside the basket with water from your hot tap. This ensures that the paper filters the coffee perfectly, eliminating ground coffee sediment in your cup.

The other way to fix this is to buy a reusable filter. The reusable ones don’t ever have issues like this. If you don’t want to do this, simply flip the filter inside out before inserting it. This will help it stick to the walls of the coffee maker’s basket.

3. Using a blade grinder. 

To save a few pennies, plenty of people grind their coffee beans with blade grinders. Compared with other types of grinders, blade grinders have been said to cause more grounds in the cup. 

The goal of grinding coffee is to have grounds that are as uniform in size as possible and appropriate for your coffee maker. But blade grinders tend to produce uneven ground in size and You can’t choose the size of grind that you need. Also, the very fine coffee grinds from your blade grinder might end up in your cup of joe because they’re able to bypass the filter.

I would choose pre-ground every time between buying pre-ground coffee or grinding whole bean in a blade grinder.

SOLVE: In order to achieve delicious-tasting coffee, you really need to invest in a good burr grinder instead of a blade grinder. 

4. Using too much ground coffee for the brewing method. 

One reason this is happening might be that you’re using too much coffee, which again may allow a build-up of water that can overflow.

This is mostly a Drip or Percolator problem; If the filter is over-fill by coffee ground, it may be difficult for water go through the filter as fast as it’s being applied, causing some of the water to pool on top and potentially overflow the filter. This causes the coffee’s grounds can sometimes “float” over the top of the filter and directly into your coffee pot.

Interestingly, espresso doesn’t have this problem because it usually flows through the sealed portafilter; but if you overfill or under grind your coffee, this will cause stall problems with the machine.

SOLVE: Fill your ground coffee to the appropriate quantity that is best suited for your coffee maker size.

5. Tamping the grounds when using a Moka Pot

When making a Moka pot coffee, do not tamp it down. Tamping just applies more pressure to the ground coffee. Excessive pressure results in greater pressure that forces through ground coffee.

SOLVE: Avoid tamping the coffee unless you’re preparing espresso. 

Making coffee with Moka pot, using the end of a spoon, tap the side of the container to help the leveling and distribution of grounds and level off the excess.


How do you prevent coffee grounds in your coffee?

As mentioned above, in order to stop coffee grounds in your coffee, use coffee coarser, use a suitable amount of coffee, ensure that paper filters are wetted so that they stick to the sides of the holder, and avoid tamping the coffee unless you’re preparing espresso.

Are blade coffee grinders really that bad?

The answer to this question really depends on what you’re using a blade coffee grinder for. Blade grinders are generally less expensive than other types of grinders, but don’t do the greatest for grinding coffee. Generally coffee enthusiasts don’t like blade grinders because they are inconsistent. Some grinds are super fine, others are huge. Burr grinders are more expensive but may be worth it because of the difference in consistency.

Can coffee filters be washed and reused?

Used coffee filters can be reused four to five times, so reuse instead of throwing away. For best results, rinse off the filter and let it dry before reuse.


Drinking a cup of coffee that full of residue really uncomfortable. But don’t quit the coffee love because everything has the solution. I hope that the above information can be resolved your problem.
