Are ice tea in bottles considered as carbonated drinks like coke

There's a lovely middle-eastern recipe for mint lemonade. I used to make loads of this stuff in my navy days. So, for a jug serving six sailors:

• Juice of about 2-3 lemons
• Six tablespoons of sugar
• nice handful of mint

Put the mint and sugar in the jug and pour about half a cup of boiling water. Stir well, and leave for a few minutes so that the mint can think about what it has done. Add lemon juice and water slowly while stirring.

The amounts may not be precise, as I used to make this in an eight gallon saucepan, and these days I make it in a 2-cup shaker.

More head = less carbonation, which will change the mouth-feel of the drink, albeit largely imperceptibly for most people (myself included). Less carbonation will also change the actual perception of flavour; it will taste sweeter, mostly.
