Neat drinks made from fat bees having energy (4,4)

'neat drinks' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being plural nouns.
Perhaps you can see a link between them that I can't see?

'from fat bees having energy' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'having' means one lot of letters goes inside another.
'energy' becomes 'e' (physics symbol as in E=mc2).
'fat'+'bees'='fatbees'
'fatbees' with letters rearranged gives 'beeftas'.
'beeftas' enclosing 'e' is 'BEEF TEAS'.

'made' is the link.
