In Missouri, alcohol can generally be purchased from 6:00 a.m. until 1:30 a.m. the following day. This applies to both on-premise (bars, restaurants) and off-premise (grocery stores, liquor stores) sales daily, including Sundays. Some establishments with special licenses, especially in cities like St. Louis and Kansas City, may serve alcohol until 3:00 a.m., but regular retail sales must end by 1:30 a.m. Local municipalities may have some variations but the state law sets the general hours. Summary:

• Regular alcohol purchase hours: 6:00 a.m. to 1:30 a.m. daily
• Bars close by 1:30 a.m. (some special licenses allow service until 3:00 a.m.)
• Sunday alcohol sales allowed with the same hours as other days (6:00 a.m. to 1:30 a.m.)
• No state open container law, but some cities may have restrictions

These hours reflect the current legal framework for alcohol sales in Missouri.
