A traditional canister of grog. Quite weak as alcoholic drinks go, but that just means you can drink several times more of it.
Grog is a trade good. Grog has no markup due to its rarity in any faction. Grog is made in a Grog Machine using Wheatstraw and Water via the Cooking skill. It is stored in its own unique storage container, Grog Barrels. It cannot be used as food.
In the description for Wheatstraw, grog is referred to as a "rum that makes you go blind".
Grog and Empty Grog Can initially both had rusty metallic icons. They have since been switched to cleaner looking bottle icons.
Despite being an alcoholic drink, many Skeletons appear to have the ability to drink Grog noted by several Grog seen in Skeleton Bar and Skinhouse HQ and other Skeleton places.
