This is all for 40d.
I'm starting to get a very large stockpile of food items, to the point where it's difficult to keep my brewers and plant processors stocked with empty barrels, so i'm looking for a way to free some up. To that end, i've decided i need to get rid of my rotten food. The only problem is, and maybe i'm just stupid and not seeing it, how can you tell in the stocks menu what is rotten and what is not? Also, once i get my dwarfs to discard all that crud, can i get them to consolidate stuff so that i don't have a bunch of not quite empty barrels sitting around? Also also, is it possible for the dwarfs to properly sort what they put in barrels. I have barrels that are just mish-mashes of different food items, plants are all stored together and meats are all stored together, but i'll have a barrel with 2 or 3 plump helmets, some cave wheat, some pig tails or what have you, all jumbled together. And since i'm starting to get a huge surplus of plump helmets (can't keep my brewer stocked with barrels, remember) I'd like to just trade some of them before they go bad, but i don't want to trade away other stuff i have a reasonable amount of (or an unreasonably small amount of) (Just realized if i trade away a barrel of plump helmets that's not going to free up any barrels since the barrel gets traded with the food, but the question still stands)
Sorry for what are probably extremely basic questions
