Anyone know where there is a good recipe calculator website where I can enter percentages into a recipe and the target OG and it will tell me the weights needed? I cant seem to find anything. Thanks.
don't know of any calculators like that reverse engineer a recipe like that...you handy with spreadsheets?
I wish I could attach files because I built a spreadsheet that does exactly what you're asking for...
I'm having trouble with any kind of file-sharing (google is being a pain and I can't get onto Dropbox at work). If you want to BM me your e-mail address, I could e-mail it to you.
What you might be able to do is enter the recipe as if you have 100 lbs, i.e., so that a 1% grain = 1lb, and then adjust the batch size until you get the right gravity. Then, provide the site allows scaling, you can scale the recipe to the desired batch size. You can do this in beersmith, so if you can't find an online site that allows scaling, download a trial version of beersmith.
I have Beersmoth on my phone, but couldnt get it to do this. I guessI will play with it more. I do most of my calculating and such on my computer.
oh...if you have beersmith, go to adjust gravity or adjust bitterness buttons up top and that will adjust your amounts after you enter in the grain percentages. I haven't used it on my phone so can't comment where it would be located there. On my computer, buttons are found below the upper-most tabs
Good excuse to use all that arithmetic from grade school. I used to calculate based on the individual potential gravities of different grains, but now I just use 37 for everyhthing, find the total amount of grain needed and then figure each grain. The recipe I've been wokring on is 1.056 for 6 gallons or 336 total gravity points. I get 72% efficiency so I really need 467 gravity points, or about 12lbs 12 oz. I'm making a biere de creme - bdg meets cream ale. 57% Heritage Malt - 7lbs 8 oz, 25% corn - 3lbs 4 oz, 12% rye malt - 1lb 8oz, 4% rolled oats - 8oz, and 2% C90 - 4oz. Not as exact as using the actual GP for each ingredient, but a lot easier and close enough for me. I use some of the free stuff online if I'm worried about SRM or theoretical IBU, I've just never felt the need for software.
