Zombie vineyard

A is a place where you can have a  grow your Grapes or Hops. Those farms come in 3 tiers:, and , where you can only grow basic grapes/hops or grapes/hops of that tier or below.

You have first to complete a quest for the inquisitor, after which the workbench in the vineyard will appear. You can use the workbench to create the zombie vineyard, more trellises, or a trunk.

Cost
You shall remove the existing vine trellis before crafting the workbench

Upgrading the Farm
You need to build a tier I farm first. Then you may upgrade it to tier II and afterwards to tier III. You have to use the fertilizer only once to upgrade the farm, it lasts forever.

Upgrading the farm to a higher tier has the following effects:

Working the Farm
Take a near the farm, hit "E" to put it to work, and "E" again to remove it from the farm. Stand next to the zombie, hit "E" to select, and then select which crop should be produced or upgrade the farm.

It takes a while for the crops to be produced - the higher the tier of the farm and the higher the work effiency of the zombie, the faster they work. You'll see a progress bar below the crop that's currently produced. After a while the products are stored automatically in a trunk of the kitchen garden. This sign on the farm means that the trunk is full (or missing) and the work is blocked until some storage space is freed up (or constructed).

Note: The number of crops produced, that are shown in this table and in the GUI of the farm, are only averages. The real numbers differ by a small random amount from those. Also the number of seeds varies around 12.
