One of the shady streets that meet Avinyó Street in Barcelona's Gothic Quarter is Carrer de n'Arai. It's not very long and only houses a souvenir shop, a couple of tapas bars, a franchise of a Greek restaurant and a pet supply store. But in 1946, the scene was different. It was in this part of the city that one of the most recognizable fragrances in the world of cosmetics was made, Nenuco cologne. Behind the master formula was Ramon Horta, an industrial engineer from the city, a member of the UGT and who during the Civil War was named director general of the War Industry of the Generalitat of the time. Until 1968, when he died, he made the elixir almost by hand. He didn't make a fortune, but the little bottles of Nenuco allowed him to live well.
