I have to confess that I didn't read it as carefully as I might have (Pretending to work here).
You have the sentence “Bottle conditioned beers have a much longer shelf life than filtered, carbonated beers and will mature and develop over years in the bottle” at the end of two paragraphs.
It's also not true. All thinks being equal, filtered and pasteurised beer will keep longer than bottle conditioned beer, but it will not develop the way bottle conditioned beer does.
