People often ask why white wines should always be drunk BEFORE red. You rightly stated in your website that it is because red wines are stronger in taste than whites, so it makes sense to progress a meal in that way. However, there is a popular saying in France that drinking a white wine after a red wine will almost guarantee you to get sick!

Having a glass of sweet white wine with dessert, after the reds is normal.

Yup I like ice wines for example! And there have been many times that I've had whites after reds for whatever reason and it doesn't make me sick They're both just alcoholic grape juice
