Being someone who enjoys a good glass of wine, especially when served with a great meal, I often find myself involved in conversations about wines.
Probably the facts that I hear quoted, and argued about, most often are how many Calories are being consumed in a good glass of wine.
I do know some basic facts on wines and calories, but I also know that the right answer to this question is based on the Residual Sugar Content and thus the category of the wine being discussed.
So, simply put, the first thing you have to know as a wine drinker is the sweetness category of your wine.
