Anyone here a regular drinker of it?

What have they done to our beer? These new twist caps are awful its like its 
a totally different beer and is tasteless and has no gas in it whereas the 
ordinary capped beer was smooth and lovely with a lovely big head rising up 
the bottle and often overflowing after the first swig.

The new stuff is harsh and tasteless. The wee local corner shop was the only 
place I could get the "original" ones and now they too have converted to the 
twist caps.

I know it wont do any good but I was going to write to them and get all my 
mates in the pub to sign the letter as they all feel the same. Anyone know 
an address or website I could use?
