What is a word for someone who denies themselves the pleasures of variety and selects high quality from a narrow range of the good things in life?
For instance, someone who likes only Renaissance art, early music, Italian cuisine, Swedish Modern design, country village holidays...
And not other varieties of art, music, food, design, holiday...
But not from ignorance. Nor connoisseurship. Perhaps (I don't know) from a desire for simplification, and it is a distinguishing personality trait.
