But you are asking about the relationship between wine and diabetes aren't you? Wine is actually low carbohydrate - very, which is a positive thing for a recreational drink if worried about blood sugar levels. And, weirdly, alcohol can stop the liver dumping lots of glucose into the blood very early in the morning, which is a common problem for diabetics (it's due to a 'misreading' of the sugar in the blood signals) - as the liver is 'too busy' dealing with the alcohol! Those are the key features about wine in relation to diabetes.
Alcohol drinking and health generally - now that's another issue! Which is what Shar and Nosher are talking to you about.
If I was you, and worried about getting diabetes, due to having both parents diabetic (I am assuming T2?), I would be where you are - in this forum! Reading stuff that seems to apply. Good one!

. And see yourself as someone with a very high chance of having inherited a high-carbohydrate intolerance, and lower the amount of carbs you may be eating, and drinking if you like sugary sodas/drinks. And make sure you are getting enough vitamin D3, magnesium and chrome in your diet. And see belly fat as a very real warning signal. ie if you have belly fat, or gaining it - take it seriously. (I just read 'Flat Belly Diet Diabetes' which I thought rather good.) (I say this, as I had big belly issues for the longest time, knew it was correlated with bad health - and felt really powerless about what to do about it. I had no idea about the role of carbs in that. And I would've liked the Flat Belly book at the time. So just in case the big belly thing applies to you.)
Yeah - and get your blood tested every six months. (I personally am a test-case in point of someone who did NOT get enough blood tests done in what was obviously a key danger period! Pre-diabetes and diabetes proper can actually come on very fast in some circumstances.)
And if I was you and worried about alcohol generally - yeah - go the 'going two or three days in a row without alcohol a week' number. That gives your liver time to clear out the alcohol in your bloodstream, it keeps a handle on any addiction issues that you might have, or might be developing (if you go three days without alcohol it is bound to put the role of alcohol in your life into focus! And then if you think that needs work - you can act on that.) I've had some seriously alcoholic friends who have done what the Swedes call 'white days' - ie have days in a row of no-alcohol, that has helped them keep a lid on their addiction. Just a lid mind - I have only seen the full AA number in American movies - where they give up alcohol entirely. But the lid can work wonders none the less - and makes sense if you are thinking about cutting down the number of bottles of wine consumed every week.
