I used to make ginger tea by simmering sliced ginger in water with lemon peel and a cinnamon stick. At that time I was eating sugar, so I used dark brown sugar to sweeten it. I bet that, if you made it very strong and sweetened it with Splenda, you could add it to sparkling water for a nice beverage. Whether or not that qualifies as "ginger beer", I couldn't say. But I bet it'd be great! (Too bad I can't drink it anymore- that much ginger is too irritating for my stomach). Let us know what you try and how it comes out!
