I saw this in the weekend Parade magazine awhile back, and I thought it sounded quite interesting - so I had to try it. It took me a while to remember to buy some more fresh ginger, but I finally got a chance to make some this week. I wasn't really sure what to expect, because I've never had ginger beer, but I figured it couldn't be bad with all these ingredients.
Since I've never had ginger beer, I'm not sure if this tastes like that or not, but it is a very refreshing drink - all citrusy with that kick of ginger, and I've been enjoying it. I usually just put it over ice and add a little water to dilute it slightly. I haven't noticed any fermenting or fizzing, even though it's been several days since I've made it.
I've been reading through some other articles and recipes (on Epicurious and Food.com to name a couple), and several of them call for yeast to encourage the fermentation, so I might try one of these next time. Or leave it out for a few days to start it. I am enjoying it enough that I definitely want to try this again. I'd love to hear any tips you have if you've ever made it.
