Established in 1900 Jamul Liquor has been around since the early 1900's. It was across the street when first established. Over the years, the business has gone through multiple owners and changes. It was moved across the street to where it is now around 1960. At the time, the post office was right next door. The post office eventually moved up the street to where it is now and a big building was built in the mid 1970's which is where Jamul Liquor is located now.
