Hello everyone! First time poster here. I've brewed Brooklyn Beer Shop's 1 gallon kit a few times before. This time around I bought 3 ingredient kits and plan to brew all 3 at once for a 3 gallon batch. My question is, should I just multiply everything on the 1 gallon recipe by three? Three times as much water at each step? What about boiling time, should I keep that the same? I don't want to screw this up, thanks!
