John Warren

John Warren is Director of Education at Aberystwyth University. He has an academic interest in the sex-life of plants and a recreational interest in all things edible. Formally a cocoa breeder, he worked on the world chocolate gene bank at the University of the West Indies in Trinidad. Whilst there he published scientific papers on the unusual sexual practices of Caribbean cocoa and also pried into the private lives of several less familiar tropical crops including the star-fruit and tree cucumber. Prior to working in the Caribbean he spent two years literally sowing wild oats at the University of Liverpool. He has made regular appearances on BBC Scotland’s Beechgrove Potting Shed. The research for this work has relied heavily upon consultations with strawberry pathologists, rhubarb tasters, chocolate scientists and coffee geneticists, better known to the author as friends.
