Why Does My Coffee Taste Salty?

Have you ever wondered, “Why does my coffee taste salty?” There are a few reasons that your coffee can taste salty. Make sure the coffee beans are freshly ground and of good quality for a perfect brew. Next, use filtered water. Third, avoid heating the coffee for too long as this will make it bitter.

Why Does My Coffee Taste Salty?

Your coffee tastes salty because the coffee was under-extracted. This means the water didn’t stay in contact with the grounds long enough to properly release all of its flavors. Under-extracted coffee can also taste sour because it hasn’t been fully brewed and has gone through fewer brewing cycles than other types of coffee.

The best way to avoid this is to ensure that you have the proper water temperature and extraction time. If you still find your coffee a little salty, you can use a coffee sweetener to make it taste better. Make sure you get the coffee sweetener from a reputable source, likely to be a coffee shop or specialty coffee shop.

Barista Tips for Diagnosing Salty Coffee

Figuring out how to fix it won’t be nearly as frustrating when you know what the most common reasons are when your coffee tastes salty! There are a few different factors that could be contributing, and once you’re aware of how each factor impacts your brew tomorrow, you’re going to see that getting rid of the salty taste will be much simpler:

Water Volume

How much coffee and water should be used to ensure the best extraction? In this area, two ideas are predominant:

  • The 1: 15 ratio (one part coffee to 15 parts water)
  • The 1: 18 ratio (one part coffee to 18 parts water)

It’s important to get the right amount of water in the coffee because it will be too salty if the coffee is under-extracted. On the other hand, if the coffee is over-extracted, it will turn out too bitter.

A Faulty Coffee Maker

If your coffee machine isn’t working right or set upright, it can make your coffee too salty. If the machine doesn’t get hot enough, or if the coffee isn’t in the machine long enough, it will turn out under-extracted.


The water you use to make coffee can change the way it tastes. In order to ensure that your coffee tastes its best, it’s important to use the right water. Only use filtered water to make coffee.

The minerals and salts in tap water can often affect the taste of your coffee and make it taste bitter. If you don’t have filtered water, you can use bottled water or distilled water. Distilled water is usually free of all the minerals and salts.

Extraction Period

The extraction process occurs when water passes over the grinds, dissolves all the chemicals, and flavors them. If there is too much water, the extraction process is called over-extraction, which leads to a bitter or overly strong tasting coffee.

However, if there is not enough water, under-extraction happens, and the coffee will taste thin or too salty. The reason is that salts and acids extract faster than caffeine and other strong coffee flavors.

Grind Size

If the grind size used in a brewing device is too coarse, the taste of the coffee will be less than ideal. Coarse grounds make it harder for the water to seep through the coffee grounds. It takes longer to extract the coffee resulting in under-extraction. If the grounds don’t fit in the filter, it can clog the needle, creating that same under-extraction effect. This is especially true of metal filters as they force the water through the grounds.

Coffee Variety

You can use Arabica or Robusta beans when you want to make coffee. Arabica makes up eighty percent of all coffee on the market. It has a smoother taste and is likely to turn out saltier than Robusta, caffeine-laden, and bitter.


The saltiness in coffee can be limited by storing it properly. Coffee stored in the freezer can be too salty, which will keep people from enjoying a delicious cup of coffee. When roasting your beans, it is important to remove portions at a time. Don’t grind all your beans at once or put them into the freezer right away – you might find them over-salted in no time!
