Why is Chic-fil-a tea the best in the world?

I used to work there and made the tea. Is was institutional Lusianne brand. Put 8 large quart sized teabags into 1 quart boiling water. Bring the water to boil, then turn it off, when the bubbles stop ad the teabags, if its too hot they will burst. After maybe 30 min or an hour, but while still hot put 4 cups of sugar and dissolve. Then pour 1/2 the concentrate into a gallon container then add water up to the gallon, then the other 1/2. It was basically by the Lusianne instructions more or less.

It could be different now. It was always fresh and whenever it got even a touch cloudy we threw it out.

It was the largest profit margin for anything we sold. CFA also spends more than other fast food makers on their insulated foam cups. Could be a factor in the tea thing. Mr Cathy recognized people kept their cups longer with the insulated foam cup, the foam also did not crush and was more visible as advertising. There may be other reasons for the foam cup but they are stuck to this concept. They are also very rich and one of the largest family owned franchisers in the world. They keep ownership of 50% of every store.
