Regional effects of global warming vary in nature. Some are the result of a generalised global change, such as rising temperature, resulting in local effects, such as melting ice. In other cases, a change may be related to a change in a particular ocean current or weather system.
In general, white wines exhibit more acidity than red wines. Acidity gives wine its crispness on the palate. A dry wine needs good levels of acid to provide liveliness and balance; sweet wine needs acidity so it does not seem cloying. Too much acidity will make the wine seem harsh or bitter; too little and the wine will seem flabby and dull.
Alcohol is Very High in Calories Per Gram. The highest calorie wines tend have the highest alcohol content. Alcohol has 7 calories per gram versus carbohydrates (sugar) which have 4 calories per gram. This means some sweet wines have less calories than some dry wines! Dry wines are commonly considered to range from around 11% alcohol to around 14%. However, a quick check of alcohol percentages of wines at the grocery store shows that many dry wines often exceed 15%. A standard 6 oz glass of dry wine with 15% alcohol has 175 calories.
