Hi all, I am just starting to brew a Young American Pale Ale kit, the Fermentation Vessel I am using was originally part of a Northern Brewer starter kit. The markings on the side of the plastic container are in gallons, would that be USA gallons? The point is that the kit states top up the wort and sugar mix to 23 Litres. It seems that the 5 gallon marking on my FV isn't enough water. So what's the best course of action for me, your thoughts please.
