I've got a
homemade ginger ale recipe here for a 3 gallon batch. I've been meaning to add my recipes to the recipe database here, since there's not much there for soda, I just haven't made it around to doing it yet.
I've bottled this and it seems that the flavors mellow and blend better after a couple of weeks. It's a bit spicier than a typical ginger ale, but milder than a jamaican ginger beer.
