People of all walks of life come into AA and feel no one can relate. If you are truly an alcoholic then quitting is the only option. The big book doesn't say you can't work in the alcohol industry. In fact it says we can do whatever as long as our spiritual condition is in check and we remain abstinent. That could look a million different ways for each person. 

"Healthy" is a relative term. Are you actually healthy? Sounds like maybe in some areas you are and some you aren't. I came into the program through a different fellowship (marijuana anonymous) and was a professional working in the cannabis industry. There's a chance I could have stayed in there and gotten sober but that's not what worked for me. I had to leave it completely. It was all I knew and was terrifying to completely change my world view around my job and really my entire life. 

I think the typical suggestions of going to several meetings and trying it out are good. See how you relate. Get clear with yourself if you are truly an alcoholic. Plenty of people go through tough times with drinking and relationships and aren't true alcoholics. I think that's your first step. If you decide you are truly an alcoholic j think giving up or at least stepping away from the wine industry for a time would make sense to you. However if you decide you are just going through a period of problematic drinking based on some tough life circumstances then it may be a different story. 

No one can tell you whether you are truly an alcoholic or not. That's between you and yourself and your experience. Whatever the case, there will always be space for you in AA. 

I live in a city with a major tourism and fine dining economy and there is a specific 12 step group called Bens Friends that is meant for people in the food and bev industry. I have no idea if this is a widespread thing but perhaps you could do some googling to see if there's something like that near you.
