Automating brewing maize is achieved by disabling all other plants for brewing, and then make a repeating order of some type.
Z-status, kitchen... tabbing... tabbing... tabbing... tabbing... nothing.
O-set orders, F-forbid... claim... claim... claim... claim... claim... nothing.
Is not?
You set 3x2 stockpile by farming plots. It will accept only seeds for one given plant/fruit and name the stockpile "(plant/fruit) seeds".
You set 12x2 stockpile to accept this plant/fruit, name it "(plant/fruit)". Then you link it to a still.
If harvesting gives other by-products, then you set general cooking ingredients stockpile to receive those.
You name the linked still as "(plant/fruit) wine/beer/ale" and you press Q select shop and click P, to access its profile. Arrow right and you press Q to set order: Brew drink from plant or brew drink from fruit. Set amount to 10. Then press c to edit conditions. Press a for item conditions. Press i to change type to drinks. Press m to change to name of brew. Press "-" to make the check happen repetitiously every season. Press n to set 200. Press q to change equation to "available is less then 200". Then escape, escape, escape and you are set.
Now you need to use z->stocks and check on how many plants and fruits are available and manually order farmers to seed some farming plots to produce some more, if you falling short on ingredients. I keep them about 500 each.
In my current embark of Dwarves going mega insane and criminal due cloth rot, I have 11 alcohols being produced in my fortress. I just check if they got ingredients enough each spring.
This is the only way to automate brewing for multiple alcohols. That is in... unmodified vanilla DF.
