The expiration date on a Jose Cuervo Margarita Mix bottle is typically imprinted directly on the glass, not on the label. This code often starts with a letter, followed by numbers. The first number indicates the year (e.g., ‘9’ for 2009, ‘0’ for 2010, ‘1’ for 2011), and the next three numbers represent the day of the year out of 365. For example, a code starting with ‘0325’ would correspond to the 325th day of the year 2010. It’s recommended to use the mix within 12 months from this manufacture date for optimal quality.
