Thanks so much for submitting a report. It has been emailed to the Rum Captain and will be actioned shortly.
Probably the most consumed rum in Cuba. For about 1$ Tumbao boxes are available at every street corner and consumed like soft drinks. People sit at the Malecon in Havana and sip their Tumbao or step by the corner kiosk to get something for their after-work hours. Tumbao actually means "knocked over" but also is Cuban slang for "having Style".
For being sold at the corner in a tetra pack not even that bad. And I certainly had many good times just sipping Tumbao.
