Pear drop is a term often used by wine writers to describe the flavor of Beaujolais Nouveau. These writers would all be British since pear drops are virtually unknown in North America. They're a traditional type of candy that the British call boiled sweets and Americans call hard candy.
They get their flavor from isoamyl acetate, an artificial flavoring commonly called banana oil. Yes, pear drops taste mainly like bananas but also like ripe pears as well. Beaujolais Nouveau gets its pear drop/ banana candy flavor from carbonic maceration, a process where whole bunches of grapes are fermented without crushing. The process produces isoamyl acetate, the pear drop flavor compound.
