Casks are all about maximizing those sweet iridium-quality profits, and the best approach is pretty straightforward. Start with starfruit wine since it gives you the highest return at about 56 gold per day with the artisan profession, though it'll take a good 56 days to finish. Ancient fruit wine is your next best bet, pulling in around 41 gold daily with the same aging time. If you're looking for quicker turnaround, goat cheese is fantastic at 40 gold per day and only needs 14 days to hit iridium quality.

Regular cheese (inside casks) work well too especially early game, and pineapple wine rounds out your top choices for decent profits. Something worth knowing - you can either go for 125 casks which are easier to manage, or squeeze in 189 if you don't mind the extra work getting to them all. Filling empty casks with cheese between wine batches keeps your profits rolling, and having the artisan profession really makes a difference with that 40% price boost. Maybe interesting - the cellar layout doesn't affect aging time so focus on what's convenient for your playstyle rather than trying to get too fancy with the arrangement.
