Agree with both these as we experienced this on our Jan/Feb '24 cruise.
We ask the Sommelier for the premium wine list and take photos of the list so we could go through it later to make a list if some of our favourites. We also ask the Sommelier for recommendations because sometimes there are odd bottles tucked away not on the list. On longer cruises the list can be updated if they get new provisions loaded as happened on our cruise.
We were lucky on our last cruise we had Joanne and Phillipe and their backups, though not as knowledgeable, were learning quickly with Jo & Phillipe's mentoring.
