Regular salt will help balance the taste of coffee and reduce bitterness.
Many people add sugar to their coffee, but there are also those who prefer to "salt" the drink. And this makes sense.
Salt contains sodium, which balances the taste of the drink, reduces the perception of bitterness and enhances sweetness. Salt adds smoothness to coffee.
Some people prefer to drink coffee exclusively with salt and perceive it as normal, like drinking a drink with milk or sugar.
Some coffee recipes include sea salt, adding salty milk foam on top of the iced drink to increase the sweetness of the drink.
Salt water is sometimes served with coffee to balance and enhance the flavor.
It is known that salt helps to preserve the aroma of coffee and emphasizes its sweetness. Salt can also smooth out the unpleasant taste of water.
Now this trick is used by many coffee lovers and gourmets.
