Editing v0.34:Using bins and barrels

{{quality|Fine|19:25, 4 April 2013 (UTC)}}{{av}}
Ordinarily, each item or stack (e.g. ≡Dwarven Ale Stew [12]≡) of items occupies one space of [[stockpile]] room. You can consolidate stockpile space by building [[bin]]s, [[barrel]]s and [[large pot|pots]] that can hold many items at once. Barrels and pots store [[food]] and [[alcohol]]; bins can store many types of smaller items, such as [[finished goods]], [[metal]] [[bar]]s, [[ammo]], and [[gem]]s. Building a steady supply of [[container]]s helps reduce the space you need for storage.

==Food Storage==

Food can be stored in [[barrel]]s and [[large pot|pots]]. Each barrel can hold up to 30 total units of food; each large pot can hold up to 60 total units. Each unit in a stack counts towards the total storage.

Foods will only be stored together if they're from the same category.  For example, dwarves will never mix plants and meat in the same barrel.

One thing to note about storing seeds is that [[bag]]s are required to put seeds in. These bags will then be placed inside the barrel or pot. Otherwise, the dwarves'll end up with one seed per tile - quite inefficient![http://www.bay12forums.com/smf/index.php?topic=79168.msg2055095#msg2055095]

==Drink Storage==

[[Alcohol]] must be [[brewer|brewed]] into either a barrel or pot; container storage limitations are not enforced for brewing, so stacks of alcohol larger than 30 are allowed in both barrels and pots. 

There appears to be no way to empty a barrel or pot containing alcohol, short of forcing your dwarves to drink the rest.

==Goods Storage==

Most non-food items can be stored in [[bin]]s; the quantity allowed depends upon the items stored. Each bin can store up to 5 [[bar]]s or [[block]]s, while 30 or more small [[craft]]s may fit into a single bin. 

==Managing stockpiles directly==

It is possible to set whether bins can be used in a stockpile with {{k|q}} → {{k|C}}/{{k|V}}. For barrels, {{k|E}} and {{k|R}} are used instead of C and V. By default, bins are used for Bar/[[Block]], ammo, gems, finished goods, [[cloth]] and [[leather]] stockpiles, and barrels are used for food stockpiles. Also by default, the stockpiles that use barrels or bins to store other items will permit a barrel or bin on each of their spaces. You can override this by specifying the maximum number of barrels and bins that an individual stockpile is allowed to utilize, using {{k|q}} → {{k|c}}/{{k|v}} and {{k|e}}/{{k|r}} to decrease and increase the limits.

==Reserving containers for other tasks==

"Reserved Barrels/Bins" is a global setting that reserves a certain number of barrels or bins, preventing them from being claimed by a stockpile until they are filled by a Workshop that requires their use. This feature is most often used to ensure that a fortress has ample empty barrels for the production of alcohol, although empty barrels are also necessary for other jobs. You can change this setting in the stockpile menu {{k|p}}. If there are 5 reserved barrels, no stockpile will claim an empty barrel until you have at least 6 lying around. In this way you can ensure that jobs like making alcohol always have free barrels available.

In the case of barrels necessary for producing alcohol and [[dwarven syrup]], they do not have to be located on a [[furniture]] stockpile. This is because the "Store Item in <container>" task only looks at furniture stockpiles for available containers. Normal production tasks behave as mentioned earlier, they will just grab the nearest barrel. You can exert some limited control over this by setting a number of reserved barrels; however, you cannot set where these barrels will be.

Though it is possible to reserve bins, there is no advantage in doing so, as no workshop tasks require empty bins.

==Barrel Reassignment==

If you have a limited number of barrels and pots (possibly due to a lumber and stone shortage because you're playing in a [[Fun]] place like the tundra) and your food stockpile is using too many barrels and you need some for booze, or if for some reason the opposite is true, you can force the dwarves through a series of steps to have the barrels switch from one stockpile to another.  Assume you have too much barrelled food and you need barrels for booze.  First, designate a small [[Activity_zone#Garbage_Dump|garbage dump]] zone nearby.  Then set the maximum barrel limit on the food stockpile way down--possibly to zero.  Don't worry, the existing barrels won't be dumped as a result.  Now view a barrel and then once inside, view each individual food item and set it to {{k|d}} for dump (but do not dump the barrel itself).  The dwarves will take the food from the barrel and throw it into the garbage zone, and once the barrel is empty they will immediately move it to a furniture stockpile because the food stockpile barrel limit is exceeded already.  Now you have a free barrel with which to [[brewing|brew]].  You can reclaim the food from the garbage dump now, and the dwarves will do what they can to store it.  Be warned that this might end up being on the floor in the stockpile which could attract flies.  Remember to set the barrel limit on the food stockpile back up to some reasonable level if you get your hands on some new barrels.

A faster way to dump the contents of a barrel or bin is to use designations. <tt>d-b-d</tt>, then select the barrels or bins you wish to dump. The container and all of its contents will be dumped separately. Then simply <tt>d-b-c</tt> to reclaim the items once they are in the dump.

==Barrel and bin material==
Heavy barrels and bins slow down hauling, so it is wise to make them from light materials when possible. Even the heaviest types of [[wood]] are lighter than any metal (excluding [[adamantine]]) - the wood of [[feather tree]]s is the best of all. As an alternative, you can place small "feeder" [[stockpile]]s that disallow barrels/bins and link them to larger storage stockpiles nearby to greatly reduce the distance traveled while carrying a heavy container.

[[Metal]] barrels are supposedly better for food stockpiles because they resist [[vermin]]; unfortunately there is no good way to convince your dwarves to allocate metal barrels for food storage aside from using them exclusively.

The material of the container also determines whether the container is [[fire-safe]] and [[magma-safe]].
