What goes in the beer will make you jump (3)

I believe the answer is:

hop

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

'jump' is the definition.
(I know that hop is a type of jump)

I don't understand how the rest of the clue works.

(Other definitions for hop that I've seen before include "Jump lightly" , "Jump; dance" , "Limp" , "Beer flavouring; jump" , "It's used in brewing" .)

I've seen this clue in The Irish News.
