I greatly apologize if this subject has been discussed elsewhere, but a search came up empty. Many of you veteran brewers have gone out of your way sharing your recipes. My confusion is derived from the IBU's many of the recipes claim to have. I use BeerSmith for my software. I can only set it for one type of IBU calculations at a time. I am in the process of getting the ingredients for Denny's Rye IPA. Where in all of these recipes do I find which scale was used for IBU's? Tinseth gives me a much less IBU and ratio than Rager does. Depending upon the style, there can be a great disparity between those two scales. Do I assume Tinseth unless the recipe notates Rager? Or the other way around? Denny, if you see this, do you use Tinseth or Rager? Is there a common default scale for these recipes you have all so unselfishly uploaded? Thank you all !! cheers!!
