The contents of a barrel may be adjusted in a couple ways. Additions may be made to any filled barrel, say cocoa nibs, berries, etc. The volume of any filled barrel can be adjusted too.

Open the Barrel Management Console and go to the Management tab. Select the barrel(s) that you intend to add adjuncts to. Click the Add Adjuncts button.
The Barrel Adjuncts form opens. The top grid shows the barrel information from the select barrels - no edits to make here. Below it is the barrel count and the Volume Change field. You can adjust the volume in each barrel if your adjustment results in such.
The bottom grid is the place to select which items you added to these barrels. Select the Item Code, the Whs (where the item came from) and the Qty / Brl. The example below shows that 1.5 LBs of Huckleberry was added to 2 barrels, so a total of 3 LBs will be used. Lastly, since the item is consumable, select the batch it came from. Add a comment if you'd like and click the Process button in the bottom left.
Note that the cost of this material rolls up into the total cost of the liquid.
Back in the BMC, click Refresh. You'll see that the Notes field updates to show the recent change to the barrel.
In the Management Tab, select the barrel you need to adjust the volume for. Click the Adjust Volume button.
The Adjust Barrel Volumes form opens. Mark the Change in volume here. The Final Volume automatically adjusts to show you the result of you change. Click Process to make it happen!
Note that the total value of your liquid stays the same.
