The bitter taste perception differs among people. This can be attributed to the different single nucleotide polymorphisms (SNPs) that each person has at the genes that are responsible for the ability to taste bitter. ?
Some of us might perceive red wine more bitter than someone else, because we carry one or more of these mutations.
When it comes to wines there are 3 basic categories: red, rose and white. Red wine is more bitter than the others because of its total phenolic content.?
As a result, anyone that is susceptible to bitter taste, might prefer rose or white wine.
