The extra heavy duty bags seal in the flavor! I've had my Original in the freezer for about 4 months [I drink other flavors as well, about 3 pots / week]. I just fill about 1/2 a can and leave in the pantry for quick access.
For even more fun, blend the different Teeccino flavors, or add your own cinnamon, chocolate, or peppermint for that special occasion!`
