A method of creating customized beverage products includes providing a multiple stream filing system suited for producing an array of beverage products. The method also includes receiving an order for a customized beverage product from the array of beverage products. The order indicates at least one characteristic of the customized beverage product. The at least one characteristic comprises one or more of the following: a beverage formulation, a beverage additive, a package size, a package shape, or label content. The method further includes instructing the multiple stream filling system to produce the customized beverage product. The multiple stream filing system produces the customized beverage product without performing an operation to reduce contamination of the customized beverage product with ingredients from a previously produced beverage product.
