Unfortunately, the alcohol is the problem here. There is absolutely no point in trying to "force" him to do anything about it with ultimatums etc as he will only start to recover if he reaches out for help because it's what he truly wants for himself. It is really hard for him because alcoholics are essentially allergic to alcohol which produces a craving effect once they start - they literally cannot stop.
In some ways it is harder when an alcoholic is highly functioning because, on the surface, it's not disrupting their life to a high degree. If he is not going on massive benders where he wakes up in jail in Ibiza or whatever, it is a lot easier for him to dismiss it as a problem and believe he can control it. (He cannot control it, by the way, and the problem WILL get worse).
If he does not look like he is likely to want to get help with this, then you have to decide if you can put up with it in the long term. As Atilla says, at the moment you are enabling him because you pick up the pieces and find solutions for him.
Al Anon is a sister organisation of AA - it is for partners and family of alcoholics and actually has its own 12-point plan which can help partners who have essentially become co-dependent with the alcoholic to break that cycle and stop enabling them.
If he does have an epiphany and realise he cannot control his alcohol intake and it is basically ruining his life, AA has an amazing track record for helping people to recover - it really can work for those who engage with the programme 100%.
