Range of beers European exported for head of Pilsner (4)

I believe the answer is:

alps

I'm a little stuck... Click here to teach me more about this clue!

'range' is the definition.
(mountain range)

I don't understand the remainder of the clue.

(Other definitions for alps that I've seen before include "Laps around mountains" , "Peaks" , "Slopes" , "Mont Blanc is therein" , "South-central European mountain system" .)

I've seen this clue in The Times and The Sunday Times.
