Which recipe site is more accurate?
|
|
http://beercalculus.hopville.com/recipe
or
http://www.tastybrew.com/calculators/recipe.html
??
Just as a test, I put in 10lb of Amber DME and;
Beercalculus: OG. = 1.090, FG = 1.022, ABV 7.0 (using WLP001)
Tastybrew: OG. = 1.068, FG = 1.017, ABV 6.6 (using unkonwn strain @ 75% attenuation)
Both come out with similar ABV, but the gravities are pretty far off. Are either of these sites any good at all for estimating O.G./ F.G.?

10lbs DME in 5.00 gallons is 1.090. I bet you have the volume off in the other one.

Just did the test myself, both on 5g. Seems like BeerCalculus is more accurate, but I don't have any software to compare it to.
Anyone here with Beer Tools or similar care to make a comparison? I'm interested in this myself, as I use BeerCalculus extensively.

more accurate... simply is. 10lbs dme + 5 gallons of water = 1.090 no matter what.

I like to use http://beercalculus.hopville.com/recipe. It seems to hit the gravity right on as long as you pick the exact ingredients that you are using. I have never used the other site though, and unless it is amazing I am going to stick with hopville. I already have some plugged in and dont want to do it again. |

My guess would be that they're assuming 75% efficiency across the board, and forgetting to remove that for extract.
90*.75=67.5 |

I got 1.090 on tasty brew, you probably forgot to change it to extract.

I get 1.068 with extract set in both Firefox and IE. I've set extract in the Recipe type and the actual ingredient.
