Adding a pinch of salt to coffee can eliminate bitterness without making it taste salty, according to caffeine enthusiasts and food experts. This simple hack costs as little as 65p and works as a flavor enhancer, similar to its use in baked goods.
How Salt Transforms Coffee
Reddit users have called salt a "game changer" for coffee, particularly for those who avoid sugar. One contributor explained: "The salt really rounds off the cup, reduces any bitterness and emphasises any complex flavours. And don't be shy with it, add a proper pinch. I add it to the dry ground before brewing." Another user noted immediate results: "I tried it this morning with just a tiny, tiny pinch and the difference was immediately noticeable."
Scientific and Historical Basis
Food experts at Bon Appétit confirm that salt "happily pairs" with coffee, noting that salting coffee is a tradition dating back centuries in countries like Turkey, Hungary, and Siberia. More recently, Vietnam has popularized coffee with whipped salted cream or milk. According to Bon Appétit, adding salt can cut bitterness and make bright fruity notes more pronounced.
How Much Salt to Add
Bon Appétit recommends starting with a tiny pinch and increasing to taste, whether added to grounds before brewing or to a finished cup. The goal is to reduce bitterness without making the coffee briny. Salt is available at retailers such as Asda for 80p, Aldi for 65p, or Aldi's Pink Himalayan Rock Salt for £1.99.
Additional tips from coffee enthusiasts include adding a bit of cold water to grounds in a French press before pouring hot water, or vigorously mixing instant coffee with cold milk before adding hot water to improve taste.
