Wine outfit bottled second vintage to make grand entrance (7)
I believe the answer is:
portico
'grand entrance' is the definition.
(I've seen this in another clue)
'wine outfit bottled second vintage' is the wordplay.
I cannot really understand how this works, but
'wine' could be 'port' (port wine is a kind of wine) and 'port' is found in the answer.
'second vintage' could be 'i' (2nd letter of 'vintage') and 'i' is located in the answer.
The remaining letters 'co' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to make' is the link.
Can you help me to learn more?
(Other definitions for portico that I've seen before include "A number of columns" , "Roofed porch" , "series of columns" , "Entrance with a roof supported by columns" , "small architectural feature" .)
