Wheat Beer from the worlds oldest brewery

This New Years Eve I was in the Newcastle-upon-tyne.
One of the pub we went into was The Head Of Steam, which I haven't been in for ages but is still good (shame they don't do the ska night they used to do but never mind).
I mention the place because it was there that I found an amazing cloudy wheat beer and I need to pass on, to anyone I can, how great this stuff is.
It's brewed by the worlds oldest brewery  1040  which I think is called Weihenstephan as that is the name most prominent on the bottle and I an therefor assuming the the beer  is called   Hefe Weissier and it's alcohol vol is 5.4% . 

It's the best wheat beer I've had so far.

Plus Tesco deliver it but don't seem to have it in store. Not sure what that's about.

Try it... If you can get hold of it  :)
