I’ve only used this for hot beverages but it has absolutely exceeded my expectations. We filled it with boiling water for everyone to use with their powdered beverage of choice (hot chocolate, hot cider, instant coffee, etc.). Afterward, we had about half the contents left and let it sit overnight to be dealt with in the morning since it was just water. When I finally dumped it nearly 12 hours after first filling it, it was still so hot it burned my hand.
