Wines (which is what I assume you're talking about) vary considerably in sweetness, too much so for any simplistic "red or white" distinction to be made.
there is more in red
it is delicious
beer
A sweet white wine has the most sugar content. It has about 16grams of sugar. A red wine has no sugar.
As a result of brewing beer and wine with a sugar and yeast, the yeast consumes the sugar and produces carbon dioxide (which makes the carbonation/fizzy bubbles) and alcohol.

White refers to the color of the wine whereas dry refers to the sugar content of the wine.
No, beer is actually less acidic than wine.
Standard servings of beer, wine and distilled spirits each have about 0.6 oz of absolute alcohol. In terms of alcohol content, they are equal. However, it is a common myth that spirits (whiskey, rum, gin, tequila, etc.) are more intoxicating than beer, which is more intoxicating than wine. It is also a common myth that drinking red wine in moderation confers more health benefits than doing so with white wine, beer or spirits.
beer wine and more beer
Champagne, because extra sugar is added when its bottled, as with all sparkling wines.
Dry white wine has approx 2 g of sugar per litre.
Wine is high in sugar and alcohol, both of which are empty calories. I'm sure you are already well aware of the negative effects of sugar. People often are not aware that alcohol itself is quite high in calories, irrespective of sugar-- which is why it is not possible to find a truly "light beer." Additionally, white wine does not have significant amounts of antioxidants, unlike its darker cousin. In short, white wine is high-calorie but does not contribute positively to nutrition nor satiety. That said, to eat a healthy diet it is more important to use moderation than to cut out certain foods entirely.
