How many tea bags are needed to make iced tea in a 34 oz mug?

lets be honest, i make some great tea brews sizing to 34oz using a single tea bag. it has a lot to do with how long you leave the tea bag to brew in your boiling hot water. i think there are also different potency tea bags, as i have tried this with celestial tea and it does not work very well. i would recommend 2 bags to start. leave them in the hot water for at least 10min and make sure to agitate the pot frequently. if you find that 2 tea bags aren't enough than add anther one on your next brew and so forth.
