The flammability of a water ethanol solution depends on the amount of ethanol vapour the solution is evolving and that depends greatly on the percent alcohol and the temperature of the liquid.
At room temperature it would need to be at over 40% ethanol to water to ignite and continue to burn from a momentary ignition but when cooking for example, wine at just 12% will ignite and burn when added to a hot pan in in the presence of a source of ignition because the heat vaporises the alcohol out of the solution faster.
