RNZ reports the Ivory Coast player, 33, told a court he thought he was drinking diet cola from a jug at a party, without realising it had brandy in it.
Toure did not challenge the charge as he was "above the permitted limit".
He was fined £54,000 - a means-tested fine - and banned from driving for 18 months by Barkingside magistrates.
"It is well known that I am a Muslim and do not drink, said Toure.
"I have always refused alcohol."
Toure was driving in Dagenham in east London at the time of the offence last month.
