Add a Pinch of Salt to Coffee Grounds to Reduce Bitterness

If your coffee tastes harsh or overly bitter — especially from cheap beans or a dark roast — try adding a tiny pinch of salt to the grounds before brewing. We are talking about a small pinch for a full pot, not enough to taste salty. The sodium ions block the bitter receptors on your tongue, allowing the smoother, sweeter notes to come through.

This is not folk wisdom — it is food science. Salt is a universal bitterness reducer, which is why a pinch of salt improves chocolate, grapefruit, and many other foods. It works with any brewing method: drip, French press, espresso, or pour-over. Start with less than you think — you can always add more next time.
