If you buy premium coffee and prepare it in a gentle, controlled way, putting salt in it will likely make the experience worse. For everyone else? A pinch might be in order.
One of our favorite coffee gurus (and maybe yours, too), James Hoffman, digs into the science of this in the video below.
He explores how a pinch of salt can take the rough edges off a less-than-perfect cup of coffee and balance out the flavor. Why does it work? Because a good cup has the right kind of bitterness (and not the brewed-in-an-unwashed-truck-stop-urn kind).
Interesting science lesson aside, the video’s worth a watch just to see poor Hoffman work his way through cups of salted instant coffee.
