What is the shelf life of Sparkling Drink Mix?

Typically, your Sparkling Drink Mix will arrive with 3-4 months prior to the "best before" date printed on the back of the label. Sparkling Drink Mix is at peak drinkability before this date. When tightly closed, store Sparkling Drink Mix in a cool, dry place. If purchased from the Outlet Page on our website at a discounted price, the sparkling drink mixes will be approaching the best buy date as specified on the Outlet Page.
