Wine drink hotel introduced to small Paris estaminet — red initially (8)
I believe the answer is:
spritzer
'wine drink' is the definition.
(I've seen this in another clue)
'hotel introduced to small paris estaminet red initially' is the wordplay.
'hotel' becomes 'ritz' (I've seen this before).
'introduced to' means one lot of letters goes inside another.
'initially' indicates taking the first letters.
The initial letters of 'small paris estaminet red' is 'sper'.
'ritz' put inside 'sper' is 'SPRITZER'.
(Other definitions for spritzer that I've seen before include "Wine mixed with sparkling water" , "Drink made of wine and sparkling water" , "Fizzy drink" , "Wine and soda mixture" , "Wine and soda cocktail" .)
