Wait, does this reaction work? If so, I might have to steal borrow it. With permission.
Somewhat you would get a weird drink... I am not at my PC so I cannot give the direct raws I cooked up for ADVANCED brewing. But you need a
[MATERIAL_REACTION_PRODUCT:BOOZE_MAT:LOCAL_PLANT_MAT:DRINK]
on the plant (right under [BASIC_MAT:LOCAL_PLANT_MAT:STRUCTUAL])
then the reagent for plants needs to look like this
[REAGENT:C:1:PLANT:NONE:NONE:NONE][HAS_MATERIAL_REACTION_PRODUCT:BOOZE_MAT][UNROTTEN]
and the product line would look like
[PRODUCT:100:150:DRINK:NONE:GET_MATERIAL_FROM_REAGENT:C:BOOZE_MAT][PRODUCT_TO_CONTAINER:D]
now I usally make use of the [PRODUCT_DIMENSION:xxx] so I have no need to do math
EDIT:
My explaination was kinda short
You need to not only modify this reaction
but you need to modify all booze producing plants (or certain ones up to you) to have a material reaction that targets the plants DRINK material.
EDIT2:
just got my hands on the raws, just remembered I PM'ed them as a BDay Gift

This is also modified so just look at how the material reaction tags are set up
