Preferred flavors

I enjoy tart flavors of flowering plants such as rhubarb, grapefruit and gooseberry. I also enjoy strong, sharp cheeses such as Cheddar and Blue Stilton. It now occurs to me to wonder if these penchants are related; perhaps it is even the same element of taste that I seek in both. The cheeses do probably contain plenty of salt but I am not typically inclined to add salt to my meals; last time we ate sushi I did not use soy sauce.
