 How many calories are in your beer?

I put together a little utilitiy to calculate this for you. If you know the OG and FG of a brew, it gives you pretty exact numbers by calculating the calories from alchol, then combining those with the calories from carbohydrates.

If you don't know those numbers (say, you have a commercial brew in your hands), it will give you a pretty close estimate (using a range of 1.010 - 1.017 as a FG range).

Finally, you can adjust the serving size... in case you want to know how many calories are in that bomber or six pack you just drank.

If you have feedback or suggestions, please send them my way. Otherwise, I hope that you find this useful.

Why would you want to do this? A solid 7.3% of the point of homebrewing is that calories don't count if you brew your own.

Seriously though, nice job man.

Heh, I won't personally use this except for academic reasons... but I thought it would be a nifty little thing to have.

I also think that the "calories not counting if you brew your own" concept is an excellent idea.

This is Great!! Thanks. Would you mind posting the formulae you used? I have built my own brewing spreadsheet in Excel that I can use for No-Sparge 3 step mashes (my preferred method) or sparge brewing. I also use it to calc my mash efficiency, attenuation, and ABV. I'd love to be able to add calories to the spreadsheet (sadly, I must lose 4 lbs) this year so I am <horror> counting calories. I want to know how long on the treadmill I have to run for each beer).

If you could please let me know the formulae, I would be most appreciative.

I have done the calculations and average between 200-250 per 12oz beer, planning to change that with the gallon brewing setup :evil:

Hmm... I never thought of this question before, but pretty awesome that you made a calculator utility for it.

Sure thing! The formulae are findable with some time and Google, it's not like this is some trade secret. That being said, the calculator is a lot easier to use, IMHO.

Note that these are the calculations for homebrew - assuming you know your OG and FG. The other version throws a few assumptions in for these numbers to give an approximate calorie count, whereas knowing the OG and FG makes it very accurate.

Assuming a twelve ounce serving... (if using another size, multiply the result by your serving size, then divide by twelve).

Total calories = ( (1881.22 * FG) * (OG - FG) / (1.775 - OG) ) + ( 3550 * FG * ( (.1808 * OG) + (.8192 * FG) - 1.004) )

Obviously, substitute in your gravity numbers above. Be careful on your parenthesis and order of operations.

My beer is apparently liquid cheescake.

Beersmith calculates this for me and honestly I can't say I've ever actually looked at it. I'm a little afraid to know.
