have you tried the usual supermarkets, polish/world foods aisle ?Meh... mine's as flat as water. Not sure what I'm doing wrong... The taste is nice enough, but it's the fizz that makes it! I'll have to google it.
I'm going to do my first TC using cartons of apple juice tonight. I'm trying to find that Lowitz (if I've spelt it right) but I'm struggling. I'm just going to look up your recipe in a sec!
