I'm almost done with a new boil kettle made from a keg. I have a recipe I've brewed before in mind for it's maiden boil, but I'm unsure of how to scale the recipe up for a 10 gallon batch. Any tips? Thanks!
That is a help, except I am looking at going from a 5 gallon recipe to a 10 gallon recipe. I understand the wanting to scale down math. But is the 5 to 10 gallon as simple as doubling the grain bill and hop addition?Software is definitely the way to go. I used a formula before but the brew software just does it all in one action. I’m using Brewer’s Friend.
But here’s the way to do it ...
“Scaling Recipes
When scaling a homebrew recipe within a reasonable range of homebrew volumes, all the ingredients scale linearly. For example, to scale a 5.0-gallon (19-L) recipe to any size, multiply the amount of each malt by the new batch size (in gallons or L), then divide each by 5.0 gallons or 19 L as appropriate. For example, if a 5-gallon recipe calls for 13 oz. of roasted barley, and you want to brew 3 gallons of it, multiply the grain weight by 3 gallons (giving you 39 oz.-gallons) and then divide by 5 gallons (giving you 7.8 oz.).
Scale the amount of hops the same way. If the recipe recommends a yeast starter volume, scale it in this manner.“

Hope it helps. Cheers.
You can use the formula to scale up or down. But yes, I’d double everything to go from 5 to 10.
