Not entirely proportional scaling
« on: December 25, 2016, 03:56:44 AM »
Just wondering:

When I scale a recipe from 19L to 25L (bottled volume), I don't get the same amounts of grain as if I just do a manual conversion like divide by 19 and multiply by 25.

Does anyone know which parameter in BeerSmith is the most likely to prevent this strictly linear relation?

When scaling a recipe, are you selecting to match the gravity, color, and bitterness of the original recipe?  This is the primary reason why the scaling is not linear.

When not trying to match gravity, color, and bitterness is that a straight scaling works on the percentage of fermentable sugars and not directly by the weight of each ingredient.
