>>In Slovenia they have their own recipe, cooked up in 1953 - Cockta (supposedly to be part of cocktails). Wikipedia doesn't say much at http://en.wikipedia.org/wiki/Cockta and I'm not sure the "dog rose berry" is the right ingredient. AFAIK, it's rose hips. And that's actually the only brown zuckerwasser that I'd drink.

>>I presume nobody here speaks Slovenian, and they never bothered to translate http://www.cockta.si/index.php?p=7&igraj=1 (the official site). But if you ever run into this, just try it. And yes, they confirm that it's rose hips.

I'm already spending too much time writing online... and this may just turn out to be a language thing, i.e. two names for the same fruit.
