What is the caloric content of alcohol in a 6-oz glass of Sauvignon Blanc wine?

  • Thread starter 6021023
  • Start date
In summary, the caloric content of wine can vary depending on the type, serving size, and alcohol content. The color of wine does not affect its caloric content, but red wine generally has a slightly higher caloric content due to its higher alcohol content. The sweetness of wine also contributes to its caloric content, but the impact is minimal and varies. To reduce the caloric content of wine, one can choose a lower ABV option, but this may also affect the taste and enjoyment of the wine.

Homework Statement


The heat of combustion of ethanol,C2H5OH(l}, is -1367kJ/mol. A batch of Sauvignon Blanc wine contains 10.6% ethanol by mass.

Assuming the density of the wine to be 1.0g/mL, what caloric content does the alcohol (ethanol) in a 6-oz glass of wine (177 mL) have?


Homework Equations


1 J = 4.184 Cal


The Attempt at a Solution


(177).106 = 18.762g of ethanol
Molecular weight of ethanol = 46.06844 g/mol
18.762/46.06844 = 0.40726 = mol
.40726 * -1367 * 1000 = -556729 J
-556729*4.184 = -2329355 Cal

Based on the given information, the caloric content of the alcohol (ethanol) in a 6-oz glass of Sauvignon Blanc wine is approximately -2329355 calories. This calculation assumes that all of the ethanol in the wine is completely combusted, which may not be the case in the human body. Additionally, this does not take into account any other caloric content in the wine, such as sugars or carbohydrates. It is important to remember that alcohol is not a nutrient and should be consumed in moderation.
 

Related to What is the caloric content of alcohol in a 6-oz glass of Sauvignon Blanc wine?

1. What is the caloric content of wine?

The caloric content of wine can vary depending on the type and serving size. On average, a 5-ounce glass of wine can range from 90-120 calories.

2. Does the color of wine affect its caloric content?

No, the color of wine does not affect its caloric content. The main factor that influences the caloric content of wine is the alcohol content.

3. Is red wine higher in calories than white wine?

Generally, red wine does have a slightly higher caloric content than white wine. This is because red wine typically has a higher alcohol content than white wine. However, the difference in calories is usually minimal.

4. How does the sweetness of wine impact its caloric content?

The sweetness of wine is determined by its residual sugar content, which does contribute to its caloric content. The sweeter the wine, the higher the caloric content. However, the impact is not significant and varies depending on the type and serving size.

5. Can I reduce the caloric content of wine?

The only way to significantly reduce the caloric content of wine is by choosing a lower ABV (alcohol by volume) option. This means opting for a wine with a lower alcohol percentage. Keep in mind that this may also affect the taste and overall enjoyment of the wine.
