11 reasons why your coffee might taste bad
1. Poor cleaning of your coffee machine
Deposits in pipes, taps and containers give the coffee a bad taste. Ensure proper and regular cleaning.
2. Improper dosing of coffee
Too much or too little of either water or coffee causes imbalance.
Check that the correct amount of coffee is used and that the machine delivers the amount of water specified.
You can check this by measuring the water that flows out.
3. Wrong grinding setting
If you use too fine a degree of grinding, the coffee will be bitter and possibly even sour.
Too coarse degree of grinding gives tame and thin coffee.
Remember that the degree of grinding must be adapted to the time the machine spends delivering the water.
The longer the time, the coarser the degree of the grind.
The shorter the time, the finer the degree of the grind.
4. your coffee is stored incorrectly
If the coffee is stored too hot and humid or has been left in an open container for too long, it loses its taste, and despite how good quality it was before, now it just tastes like crap.

5. The coffee bed in the filter is uneven
This is mostly a big issue with espresso machines, but If the coffee bed is not flat, some of the coffee will have less contact with the water.
In the worst case, it never comes in contact with the water.
The result is a weak and thin coffee.
Always check that the coffee bed is neat and even.
You adjust this easily by shaking the filter a little.
6. Wrong temperature of the water
Too hot water produces bitter coffee.
Too cold water produces thin and flat-tasting coffee.
Check the temperature by holding a thermometer under the water jet at the outlet.
The water should be between 92 ° C and 96 ° C.
7. Incorrect contact time between water and coffee
The contact time is related to the degree of grinding. See point 3.
You should check if your machine delivers the water later or faster than specified.
Take the time from when it starts flowing until it ends.
If the time is wrong sometimes you have the option to change the settings. If not, then contact the supplier.
If you have a machine that is designed so that it does not achieve the correct contact time, you should consider replacing it.
8. Too little coffee in relation to the capacity of the machine
Never make less than 3/4 of the capacity of the machine.
If you make less, the contact time will be too short and the coffee will be tame in taste.
In some cases, the height of the coffee bed will also be too low, so that the water flows through without being in particular contact with the coffee.
9. The water quality
Poor water quality can put a bad taste on the coffee.
Always use cold tap water.
Never lukewarm or hot, or water that has stood for a while.
Water quality is surprisingly important. If you’re interested I recommend you read this article on the subject.
10. The water is distributed unevenly over the coffee
Here are several things that can affect:
- The spray head, which delivers the water, may be partially clogged due to a lack of cleaning. Please take out the spray head and clean it.
- Check the water pressure. If it is uneven, this may also be a cause.
- Check that the machine is horizontal. Check that the filter is straight.
11. The coffee
In some cases, there may be something wrong with the coffee.
Then the coffee supplier would like to be informed about this.
Return the coffee in the original packaging together with your remarks.
