Kind of red coat worn by clubber, periodically (6)

'kind of red' is the definition.
I know nothing about this answer so I can't tell whether this works.

'coat worn by clubber periodically' is the wordplay.
'coat' becomes 'mac' (mac is a kind of coat).
'worn by' indicates putting letters inside (outside letters are worn by those on the inside).
'periodically' indicates alternate letters (letters must be selected 'every so often').
The alternate letters of 'clubber' are 'lbe'.
'mac' enclosing 'lbe' is 'MALBEC'.

Can you help me to learn more?
