Distilled liquids provide enhanced flavor stability, artificial sweeteners, vitamins, and / or color components. Due to the addition of one or more agents to increase viscosity, the consistency of liquid drinks has increased stability. The concentrations of liquid beverages described in this report provide enhanced flavor stability for those components that are highly degradable in acidic solutions despite their low concentrations (i.e., about 1.8 to 3.1). In some ways,The liquid beverage concentrates disclosed herein remain stable on the shelf for at least three months when stored at 21.11 ° C (70 ° F) in a closed container and can be diluted to prepare flavored beverages with a desired flavor profile and with little or no degradation of taste. Claim 1: A flavored liquid beverage concentrate having a pH of about 1.8 to about 3.1, the concentrate comprising: about 0.1 to about 15 percent acidic； about 0.1 to about 40 percent flavoring；and an agent that increases viscosity in an amount effective to provide a viscosity of about 7.5 to about 100 cP as measured using a Brookfield viscometer, S00 Axis at 50 rpm at 20 ° C, where the concentrate has a concentration such that when diluted with a drinking liquid at a ratio of approximately 1:15 to give a beverage, the concentrate supplies approximately 0.01 to 0.8 percent acid by weight of the beverage.Concentrados de bebida líquidos que proporcionan estabilidad potenciada al sabor, edulcorantes artificiales, vitaminas, y/o ingredientes del color. Los concentrados de bebida líquidos obtienen estabilidad potenciada debido a la inclusión de uno o más agentes que aumentan la viscosidad. Los concentrados de bebida líquidos descritos en la presente proporcionan estabilidad del sabor potenciada a los ingredientes que son muy propensos a la degradación en soluciones ácidas a pesar de los concentrados que tienen un pH bajo (es decir, aproximadamente 1,8 hasta aproximadamente 3,1). En algunos enfoques, los concentrados de bebida líqu
