I'm about to move my Java Stout into the secondary, where I need to add 8 cups of coffee. I have just over 5 gallons of brew in my primary right now, and am afraid that when I add it with the 8 cups of coffee in the secondary I won't have much head space.
How much head space do I need in my 5 gallon glass carboy to be safe?
