Hop Bill Scaled Recipe

Post #1 made 15 years ago
Hi... I haven't done a BIAB yet but am working up to it. Just getting my gear. Looking at the calculator, under the hop bill tab, I want to know why the hop bill needs to be increased? I guess the grain needs to be increased because of the grain going in the full volume of water BUT surely the hops would remain the same as the boil would be just like a 3 tier stage? Can someone explain this? Cheers

The calculator scales the grain bill to the desired grain bill based on the desired brewlength, which may be different to the original grain bill's brewlength

This is just like scaling a recipe from 2 people to 3 people

The hop bill is scaled in the same way, except it is also scaled based on the gravity throughout the boil, which again, has an effect

So, the grain and hop bills are not being scaled because you are using BIAB instead of 3V, but because the quantity you are producing is more or less than the original recipe called for
