Hostelries talk wine up, regularly rubbish

I believe the answer is:

gastropubs

'hostelries' is the definition.

'talk wine up regularly rubbish' is the wordplay.
'talk' becomes 'gas' (I've seen this before).
'wine' becomes 'port' (port is a kind of wine**).
'up' is a reversal indicator (in down clue: letters go upwards).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'rubbish' are 'ubs'.
'port' reversed gives 'trop'.
'gas'+'trop'+'ubs'='GASTROPUBS'

I've seen this clue in The Telegraph.
