On the comeback flight it was funny that FA was very embarrassed due that:
I was able to drink one glass wine(sparkling finished before they came to my row-11A)
-sparkling wine has been finished-they had only 2-3 bottles
-red/white wine has been finished-2-3 bottles
-glasses has been finished

beer was available

as she told us it was 9th flight in general this day and of course in business class was ca40 passengers. To LPA 44 only in business without counting economy but situation was better in spite of finish sparkling wine , normal wines and beers available whole flight.
