Providing wine product onboard was started by Western carriers are those European have a good knowledge and understand of wine and related product... As fart that they have different wine for different type of meat that they eat... And as wine is part of a meal in Europe, they have to serve wine during meal time...
Slowly to now, people drinking too much and getting drunk is a big issue not only for airlines, but also for society... So sometimes drunk people do cause huge distruptions during flight and cause problems like fighting etc...
It is easy to tell airlines just to cut wine product onboard so passenger cannot get drunk... But which airlines will dare start doing that? As this would not be a good move as its against the majority who like drinking wine as part of the meal and hardly get drunk...
As there is still only a minority who get drunk onboard... I think its not necessary for airlines to cut wine product to go against the majority... So best way may be for the airlines to control the wine consumption for passenger...
For now, majority of the airlines only get crew to define if the passenger is drunk or not by asking them questions and crew have the right to stop serving wine product to a passenger who they think could be drunk or close to drunk... But of course this differ between crew... And usually airlines would tell crew to inform each other of which passenger should not consume anymore wine product... To hopefully aviod passenger getting drunk...
If the situation became too unstable... The captain do have the choice to divert the flight to off load the drunk passenger... Or to force it seat still in his/her seat if she is causeing trouble... Although the crew dont have much training on facing drunk passenger, but the ISM would and the captain have the right then to do anything if he think that passenger is causing problem...
