That minimum amount by law in The Real World is because it is physically impossible - unless you just add together a bunch of artificial flavours, to 'brew' ANYTHING with a zero alcohol content - even bread dough has a minimum amount, evaporated out in the baking process - adds to that smell you know - even if it goes thru an 'alcohol removal' process - a tiny amount will remain.

I recently posted an article about a US Chemist that sold nothing that would upset anybody with an axe to grind going broke in 18 months cause they sold nothing that people actually wanted - same sort of lack of contact with reality... legislators have even been reputed to pass laws redefining the value of Pi...

Sigh...
