Before the introduction of CAN-POUR, 98.4% of all licensees poured a traditional one ounce (30ml) shot glass. Liquor control and licensing laws across Canada state that licensees must pour a Canadian ounce. CAN-POUR offers the only Canadian ounce shot glass that has been tested for accuracy by the Government of Canada. A CAN-POUR shot glass is designed to look identical to the traditional 30ml shot glass. Using CAN-POUR, you can generate the same revenue while purchasing 7% less liquor.
