Mmm also an interesting thread. Do be aware that various universities around the world have discovered that about a third of the population have wheat problems. They may not realise it, a headache after a drink, falling asleep about 30 minutes after something all will end up as a diabetic. Yes GM you makes sense but its not as simple as that. There are some drugs that may affect your genetic makeup but!!!!
So avoid any wheat product, some alcohol is made with wheat eg blended cheap and even some not so cheap whiskies. I glass for me and of to bye byes. Eat a bread made from hard wheat, Bye Byes, beers from wheat BB, and so on, however, malt whisky mais whisky, Brandy then look out table here you go!
Bread, bread made from Rye, barley etc have no effect, yet from hard wheat known as ble in France as opposed to froment (soft wheat) causes serious black outs. Incidentally I tackled certian UK suppliers about this and Weetibix said that mostly they only use locally grown soft wheat and Ryvita told me they only allow soft wheat into the factory!
Now to your vodka, some sugars are made from hard wheat, especially cheap vodkas, also be aware that some sugar alcohol actually made from wheat and fraudulent got into the UK drink chain.
My tipple now is Calvados, you cannot make that with wheat. Incidentally some naughty wine makers have been "fortifying" their wines by lumping loads of hard wheat into their wines. (That is only detectable by me if I fall asleep)
I produced evidence to the fact of many accidents happen in France after dinner to lorry drivers falling asleep after midday meal. And what is the NORMAL midday meal, oh yes, a glass of cheap beer, (made with hard wheat), a load of bread, (Hard wheat), something and chips, bread and cheese. You will notice the amount of hard wheat. Oh and what percentage of the French become diabetics, oh yes above 33%.
The grain people have just ignored it even though a professor there acknowledged the inference.
So wheat red and white seems OK, maize, Durham wheat (not really wheat at all, but often called hard wheat which it is not) OK, mais, Rice, and so on seem not to be problematic!
