Made a full gallon of this and it’s been in the fridge for the better part of a week. This morning, it was so oppressively humid when we woke up (air conditioning at Shabby House leaves a lot to be desired) I ran straight for the jug. For a cheapie tea, it has stayed pretty fresh, doesn’t have that astringent/detergent taste that a lot of grocery store teas do. No, it’s not high quality, but when you need to guzzle in large quantities, it’s suitable.
