Oh thank you for the question!!

If we mean all potable things and not just booze... Kanae is a green tea person first and foremost, though coming to Eorzea and given who the two people she's closest to are (Y'shtola and Urianger) she's developed a fondness for black tea with milk and sugar... for booze though she prefers sake to stuff like ale
Y'shtola I see as a black tea with cream drinker, and clearly the game shows she drinks wine so I'd be surprised if she didn't like it.
W'htal... what DOESN'T he drink? His first love is grape wine though so Wineport is his favorite place in all of Eorzea lmao. Though I know by Shadowbringers Thancred tries to cut back on the alcohol I still think he has a soft spot for a good Limsan ale... and well. Urianger really shouldn't be near the stuff but . Drunk him is cute
