This very large bag contains 5 kilos or 11 pounds of Valenciano rice. That's equivalent to 22 1/2 cups, enough for 45 to 70 servings (depending on appetite).
Valenciano rice is a close second to bomba rice in terms of flavor and performance. It doesn't absorb quite as much liquid, but it still performs admirably in paella. The 5-kilo bag will carry you through many paella parties.
