Iced Cold Brews (non-nitro) are built in a _______ and follow standard drink recipes.

Iced Cold Brews (non-nitro) are built in a mix cup because this cup is specifically designed for preparing and mixing drinks before they are poured into the final serving cup. The use of a mix cup allows for the precise measurement and blending of ingredients according to standard drink recipes, ensuring consistency and quality in the preparation of the beverage. This method is especially important for drinks like Iced Cold Brews that may require specific ratios of coffee, ice, and flavorings.

Other cup sizes do not serve this purpose, as they are used primarily for serving the finished drink rather than for mixing or preparation.
