scaling up question

Is scaling up from say 12 L batch size to 36 L batch size linear with respect to amounts of ingredients (3 x more) assuming processes are almost the same. (the cooking pot is bigger, the fermentor is bigger, temperature come up and cool down time longer).

I am doing a whole grain (various malts with corn and wheat flakes), hops and lager yeast. Process is a temperature step up mash.



Any comments of scaling up would be well received. Thanks

Yep, the recipes are scalable. Works both ways. A 5 gallon batch to a 2.5 gallon batch is just cutting everything in half. You can input the 12L recipe in a calculator Brewer's Friend for instance, take note of the metrics, OG/FG/IBU, then triple the ingredients and see if it's the same to make sure.

Thank you!
