Revise alcohol laws relating to self-service

This bill amends Montana's alcohol laws to clarify and expand regulations around self-service beer and wine in licensed retail establishments. It allows customers to pour their own beer or wine from large containers like pitchers or buckets, and permits the use of approved electronic devices that measure and limit pours under staff supervision. The legislation also updates rules for facility layouts, permitting noncontiguous storage areas for alcohol and allowing delivery of beverages to hotel guests with proper age verification. These changes aim to modernize how alcohol is served while maintaining oversight to prevent underage drinking and overservice.
