Well, I don't know what you guys put in the wine down under, but one brand at least, "Crocodile Rock", gave me one hell of a case of tintinitis (ringing in the ears). When the "white noise" is drowning out car noise and freeway traffic, you know it's bad. I went out and bought a bottle of ginkgo biloba pills and popped them for a couple weeks (ginko is approved for treatment of tintinitis in Germany).

Further experiments confirmed it was the Crocodile Rock. Later, one morning, I woke up with tintinitis again and wondered, "why the hell is this back". Then I remembered I'd absent mindedly finished off a bottle I found in the fridge, and sure enough, it was Crocodile Rock.

Eventually, I'll try more Australian wines, and if this problem doesn't reappear I'll exhonerate the country at large, but Crocodile Rock is off my approved substances list (incidentally, it did taste pretty good).
