Mulling over superconducting wine

Japanese scientists have discovered that mulling their red wine with iron-based compounds can induce a state of superconductivity, the same effect occurs with sake and shochu, they claim. Iron-based compounds can be made to superconduct after exposure to the air, but the process usually takes, months; 24 hours in hot red wine is enough, the team from the Japanese National Institute for Materials Science says. The scientists are at a loss to explain why hot alcohol can speed up the process of converting an iron compound into a superconductor. However, it is known that iron-based compounds are readily magnetically ordered whereas in superconductivity, this magnetic order needs to be suppressed, elements present in the alcoholic drinks seem to be substituted into the iron compounds and so preclude magnetic ordering.
