From the Wine Expert Abilities (Z-man English edition, page 15):This Tile can be used before performing an Action, before performing a Bonus Action or before the Fair Step. It allows the Player to take back 1 of his barrels from the Export, Sales, Benefits or Managers Areas. The barrel is returned to the Player's supply, allowing him to reuse it, even immediately.
The tile you mention specifically say it's used during the Vineyard action.
The tile in question cannot be used during an action.
