Iced green teas come in both caffeinated and caffeine-free options. Typical caffeinated ready-to-drink and brewed green teas fall in the ~30–45 mg range per 8 fl oz serving; examples in product listings include 33 mg per cup, 31–45 mg per 8 fl oz serving, and certain RTD varieties listing about 30 mg of natural caffeine.
Yes. Several canned iced green teas emphasize aluminum cans and recyclable packaging—some listings specifically highlight "infinitely recyclable" aluminum cans and recyclable packaging as a sustainability feature.
Iced green tea is sold as ready-to-drink (single-serve and multi-serve bottles and cans), tea bags for brewing (including family-size boxes for pitcher brewing), and concentrated mixes that you dilute with water or sparkling water.
Typical options include single-serve cans or bottles around 12–16 fl oz, multi-packs (for example 4‑pack or 12‑pack), multi-serve bottles or cartons in the ~42–48 fl oz range, and boxed tea bags commonly sold in counts like 16, 20, or 24 as well as family-size boxes for pitcher brewing.
For tea bags: steep in hot water (common guidance is about 3–5 minutes), then pour over ice. For concentrates: dilute or mix with water, lemonade, or sparkling water (product listings commonly show mixing in equal parts), then serve over ice.
Matcha almondmilk lattes in these listings show a specific sugar amount (example: 5 grams per serving). Other ready-to-drink green teas are more often described with label claims such as "Zero Sugar," "Zero Calories," "Just Sweet Enough," or noted as unsweetened/no added sugar.
