Every so often my wife asks me if I notice a particular smell in the house or garden. I can, when asked, often detect an odour, but I seem to have a much less sensitive nose than she does. I do however like a good red wine with an earthy bouquet. Each bottle I open has an unusual combination of such aromas. My wife often cannot detect the differences in smell between these wines. Does that mean that I have a more delicate sense of smell after all?
