Tarberry is a consumable item in Fallout 4.

Characteristics[edit | edit source]

Tarberries are small, purple berries of the tarberry plant, itself a water-grown crop ostensibly similar to cranberries. It is used in the Lock Joint syringe, the Berry Mentats, mirelurk jerky and in Fancy Lads Snack Cakes.

Berry Mentats[edit | edit source]

Tarberries are a required component of Berry Mentats, which give a substantial +5 boost to Intelligence and thus earned experience. Under normal circumstances, this works out to about a 16.666% bonus. This is likely the reason that tarberries are one of the rarer crops in the Commonwealth.

Farming: The Slog[edit | edit source]

Tarberries can only be farmed at the Slog. A swimming pool containing nine farmed tarberry plants, which can normally be harvested once a day. The player character is not required to have the Slog as a settlement to harvest the berries, but the settlers must be alive. Additionally if one does control the settlement, settlers must be assigned to farm them like typical crops.

Most companions will comment on the ingenuity of farming tarberry in a former swimming pool, alluding to the general Commonwealth knowledge that tarberries are rare and difficult to cultivate commercially. The ghouls at the Slog say that they have the best tarberries in the Commonwealth, but truthfully, they have the only cultivated tarberries in the Commonwealth.

Locations[edit | edit source]

Tarberries cannot be planted, and can only be found growing in ponds, swimming pools, and on any surface of still water. General goods vendors (i.e. Myrna and Trashcan Carla) occasionally carry up to three tarberries for sale.

Locations notable for quantities of renewable tarberries:

The Slog-region
  • Ten located adjacent to Parsons State Insane Asylum:
    • Seven south on the nearby lakeshore opposite the Slog.
    • Three north in the pond near Gunner's freeway outpost.
  • Three south in a pond adjacent to three-way junction (southwest of the Slog).
Other high-density regions
  • Four located on the northeastern shore of Dark Hollow Pond; two of the four are against rocks and are more difficult to spot.
  • Far Harbor (add-on) Eight located in a large pond northwest of MS Azalea.

Behind the scenes[edit | edit source]

Massachusetts is known for its cranberry bogs at Cape Cod, southeast of Boston. The tarberry is a riff on that, as cranberries only grow in water and are similar in shape and size to the tarberry image. Also, the fact that they only grow in water would explain why they can't be planted elsewhere.
