Which of the following spirits has a mash bill primarily made from wheat?

The spirit made primarily from wheat among the listed options is Red Arrow Vodka. Wheat is a common grain used in the production of vodka due to its ability to create a smooth and clean flavor profile. Vodka made from wheat typically has a soft, slightly sweet taste, which can appeal to many palates. In vodka production, the choice of grain significantly impacts the final product's texture and taste, and wheat is favored for its neutral character.

In contrast, Last Feather Rye is primarily made from rye grain, which contributes to its spicier and more robust flavor profile. Field Vodka may not specifically highlight wheat as its base, and Silver Cross also does not primarily utilize wheat in its mash bill. Therefore, Red Arrow Vodka stands out as the correct answer due to its composition and the characteristics imparted by the use of wheat in its production.
