Had a New Type of

It came in a can and did not have the Widget thing in it.    It was not Extra Stout.      It was pored into a glass then put on this sonic thing that made a head form.  Did not taste as good as a draught, didn't even look like a really Guinness beer, i.e. the bubbles didn't fall.   It was kind of flat and bitter, bitterer than regular Guinness and not as bitter as an Extra Stout.

Any one esle experience this?   What is your favorite form of Guinness?
