The writers of "Home" got gespar from the RPG manual and guide to Vulcan culture "The Way of Kolinahr." There, it is described as a temperate region flora, that tastes like a "cross between a pineapple and a Rigelliankir – tangy and piquant." The method of preparing it is described as splitting its reddish-pink outer layer and removing a seed pod in the center for replanting. The rind of the gespar is said to be used in the production of soap and perfume since ancient times.
In the final draft script of "Home", gespar was described as a red fruit.
