Quality

What's it with Vittel, seriously! Flavour-wise it's fine, it sits right up there with Evian, being French and all. BUT what's with the crystallised grains?! Virtually every bottle I bought so far will end up crystallising at some point and they end up feeling like this grainy thing. I tried to contact them at some point but found it impossible on their website, I'm appalled. When I'm back in England I'm sticking to Evian (as I always do), here Evian's just real expensive and I don't even see why, they come practically the same distance anyhow.
