How to calculate beer calories [complete guide]

 calculating beer calories depends on two factors which is given below

if you directly want to see the formulae to calculate beer calories, directly go below 

1. original gravity
2. Final gravity 

These don't relate to physics directly, these are the term related to both beer craft industry and common density of the nonalcoholic beverages.

Original Gravity
 It is the relative gravity before the fermentation process. 

Final Gravity

it is the relative density measured after the completion of the fermentation process.

 ABV = (OG - FG) * 131.25. ABV = alcohol by volume, OG = original gravity, and FG = final gravity. So, using this formula with a beer having an OG of 1.045 and a FG of 1.012, yourABV would be 4.33%.

[NOTE: this ABV is not the calorie content, ABV is the alcoholic percent which has developed after the fermentation process. ]

Now, for calculating the beer calorie two things to be known by you

1ml of alcohol 0.8g weight and 1g of alcohol has 7 calories.

Calculation:

suppose alcoholic content is 4.33%. then for simple calculations

100ml of quantity will have 4.33ml of alcohol.

4.33ml alcohol = 3.464g of alcohol

3.464g of alcohol= 24.248 calorie

BEER CALORIE=[(OG - FG) *131.25]*0.8*7]=[OG - FG]*735

(the above formulae is standard for 100ml.)

this formula is used by the craft beer makers. yes, those fancy craft where you have gone many times. do you know how they used to make beer so easy which is just an industrial process
