The Castle had a large area set aside for storerooms for storing grain and other agricultural produce that formed part of the tributes the lords received from the vassals as part of their feudal rights.
In the case of Torredembarra, they received half a tithe of the grain and grape harvest (i.e. half of the eleventh part), a tithe of saffron, flax, hemp, cabbage, onions, garlic and all kinds of legumes; three dried cheeses from the vassals who had livestock; thirty-four quarters of corn and eleven of barley for census purposes; eight pairs of capons; two rabbits; forty pairs of chickens; and a quarter of the olive harvest.
In the late nineteenth and early twentieth centuries, the storeroom was used as a cask workshop.
