There is a secret ingredient that will turn your cheap, grocery store wine into tasting like expensive, wine-connoisseur wine!
The secret ingredient is salt and adding just a few grains can balance out uneven flavors in the wine. By adding salt, it makes the wine taste more savory.
In doing so, you can impress your friends by saying it was bought in Italy when you really bought it at a 7-Eleven! They won't be able to tell the difference unless they look in your kitchen and see the brand.
