I believe the answer is:

macon

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

'what's bottled up' is the definition.
I can't judge whether this definition defines the answer.

'soldier around commanding officer?' is the wordplay.
'soldier' becomes 'man' (man can mean a soldier).
'around' is an insertion indicator.
'commanding officer?' becomes 'co'.
'man' placed around 'co' is 'MACON'.

'by' is the link.

Can you help me to learn more?

(Other definitions for macon that I've seen before include "Wandering (knight)" , "red" , "French wine region" , "French wine district" , "A heavy Burgundy" .)
