'briefly with one of those sensational mouthy types?' is the definition.
I can't judge whether this defines the answer.

'drink american beer' is the wordplay.
'drink' becomes 'taste' (I can't explain this - if you can you should believe this answer much more).
'american beer' becomes 'bud' (I've seen this before).
'taste'+'bud'='TASTEBUD'
