In old Sicilian TANNU means "back when…", as in, "back to when agriculture was completely natural". The growers use neither pesticides nor fertilisers but an organic method, sexual confusion, which disrupts male/female recognition of unwanted insects by continually diffusing synthetic equivalents of the sex pheromone in the air around the plot. The males are disorientated and cannot locate the females. Mating is thus prevented, there are no destructive caterpillars and the fruit is preserved without the need for the usual chemical sprays. This is also one of the proofs that Tannu respects the environment and biodiversity. Tannu wines go very well with traditional Italian food, such as pizza or pasta.
