While my dwarves had been subsisting happily off kitten meat, plump helmets, and fat roasts for years I got sick of seeing the "sick of drinking the same old booze" message so I decided to diversify. First I converted my 3x3 pigtail plot from creating ungodly impossible to store amounts of cloth to strictly brewing (I still have around 150 cloth from my first year of growing pigtails) and set them for brewing.
My brewer kept on making mostly plump helmet wine, occasionally making a barrel or two of ale and I didn't really care too much. But recently I managed to buy a handful of sun berries from some tree hugging hippies and after a while I have a big stockpile of seeds, and a nice little plot in the sun where I grow the things with a lovely trail of vomit showing the way like an ant marks its path to goods with pheromones.
Now I have a rather large stockpile of sunberries, plenty of barrels, and I constantly have to be brewing booze and yet Sunshine (which gives my already spoiled to death dwarves thoughts of decadent booze) is only like 1/20th of the stuff produced even thought the plump helmets and sunberries are directly next to eachother.
I was hoping the brewers would selectively use these to produce top notch booze and only fall back on plump helmets to keep the dwarves from getting sober (God forbid) But they don't! I have crap loads more wine than sunshine and it gets drunk really fast too!
