The salt takes the top of the bitterness. Try it in a coffee grade of poorer quality. Or if you just do not like coffee.
Have you ever been drinking coffee with salt? No, well, unless a ghost had swapped on sugar and saltbushes.
But now the wine and spirits vinepair has made it for you, apparently in earnest. And a writer now suggests that you do it too.
There are no big quantities, just a pinch tip added the ground beans during the brewing or until the finished brew will take the bitterness, it is said.
For salt reduces bitterness. It is a known feature of the kitchen, where chefs use salt and bitters in combination to achieve goodness. Therefore, it will probably also make your coffee more gentle and compassionate.
But I would not recommend it if you drink good quality coffee or if you like the coffee for its bitterness.
But it can certainly be a good replacement if you belong to those who can not get the black drink down without large amounts of milk and sugar. And possibly also for you who can not escape the caffeine pillow and like that variety, but have to thank you for a hay from the vending machine.
With this the tip is at least given on.
