Caffeine in Drinks

McDonalds Sweet Tea

McDonalds Sweet Iced Tea is a popular non-soda beverage choice at McDonalds restaurants. It comes in 4 sizes and also in an unsweetened version.

The amounts above are for a LARGE (32 fl oz) size. The caffeine amount originally came from McDonald's - but these are no longer published. The USDA nutrient database suggests 4.14 mg per fl oz for an Iced Tea (including the ice). This would make the Large McDonald's Sweet Tea have about 132 mg of caffeine in it.

There originally was 69 grams of sugar in a 32-ounce sweet tea, which has more sugar than 2 1/2 snickers candy bars. McDonalds has since lowered this to 38 grams per 32 fl oz.
