Dark & Stormy with Old Jamaica Ginger Beer Soda. The only ginger beer I've seen so far. Well, not true.. I've seen some other ginger beer. Upon closer inspection it said "beer flavored with ginger aroma".. um, no thanks.
That ginger beer is ok. Definitely good for the price (0.7€ per 0.33l can). Could use some more spice. Guess I will have to experiment more to create a taste similar to that in my syrup.. JM uses ginger and lemon juice in his ginger beer.. unfortunately, he just gives amount of "ginger juice" and I left my champion juicer in Hamburg (moreover, it wouldn't really work to juice ginger).
I think just letting it steep is the key whereas simmering isn't so good (at least not for over an hour, see in the bar thread).
Now that I think of it, I probably have to read those comments at JMs article. I'm 100% sure that there will be lots of useful information.
