Plain iced tea is naturally gluten-free — tea leaves and water, no gluten involvement.
Yes. Plain iced tea (bottled, canned, or fresh-brewed) is naturally gluten-free. Lipton, Snapple, AriZona, Pure Leaf, Gold Peak, Honest Tea, and other major bottled iced tea brands are widely treated as gluten-free. Lipton’s published FAQ confirms no ingredients are derived from gluten-containing grains. The exception is “hard iced tea” (Twisted Tea, etc.) which uses malt-based fermentation and is NOT gluten-free.
Iced tea is one of the easier gluten-free beverages on the menu — whether fresh-brewed at a restaurant, poured from a bottle, or shaken from a pitcher at home. The recipe is tea and water (plus sweetener if you want it), and tea is naturally gluten-free. The exceptions are flavored variants (most still GF but worth verifying) and the hard iced tea / alcoholic category, which is malt-based and not GF.
Why Plain Iced Tea Is Gluten-Free
Iced tea is brewed from Camellia sinensis tea leaves — the same plant that produces hot tea, green tea, white tea, and oolong. Per FDA labeling rules, none of the gluten-containing grains (wheat, rye, barley, oats) is involved in tea production.
Per Lipton’s official iced tea FAQ: “None of the ingredients in Lipton iced teas are derived from grains or flours that have been linked to malabsorption syndrome associated with gluten sensitivity.” Lipton commits to disclosing any gluten ingredients on the label.

Frequently Asked Questions
Is iced tea gluten-free?
Yes. Plain iced tea is naturally gluten-free — brewed from tea leaves and water with no gluten involvement. Major bottled iced tea brands (Lipton, Snapple, AriZona, Pure Leaf, Gold Peak, Honest Tea, Brisk) are widely treated as gluten-free. Per Lipton’s published FAQ, no ingredients in their iced teas are derived from gluten-containing grains.
Is Lipton iced tea gluten-free?
Yes. Per PepsiCo’s official Lipton FAQ, none of the ingredients in Lipton iced teas are derived from grains or flours that have been linked to gluten sensitivity. Lipton bottled iced tea typical ingredients (water, HFCS, citric acid, sodium benzoate, sodium polyphosphate, natural flavor, calcium disodium EDTA, colorants, tea) contain no gluten sources.
Is Snapple gluten-free?
Yes for plain teas. Snapple’s plain iced tea variants (lemon, peach, raspberry, half & half) are widely treated as gluten-free by celiac advocacy databases. Snapple Juice Drinks and unusual flavor variants should be verified individually.
Is AriZona iced tea gluten-free?
Yes for standard teas. AriZona’s plain iced tea variants (Green Tea, Black Tea, Lemon Tea, etc.) are generally treated as gluten-free. AriZona “tea drinks” with unusual flavorings or added thickeners should be verified per can.
Is hard iced tea (Twisted Tea) gluten-free?
No. “Hard iced tea” products like Twisted Tea are malt-based alcoholic beverages — they use barley malt fermentation as the alcohol base, with tea flavor added. Barley is one of the FDA-defined gluten-containing grains, so hard iced tea is NOT gluten-free and not safe for celiac.
Is restaurant iced tea gluten-free?
Fresh-brewed unsweetened iced tea at restaurants is gluten-free (tea + water). Sweet tea adds sugar (also GF). The exceptions are flavored syrups, “specialty iced teas” with added components, and boba/bubble tea flavor syrups at cafes — verify with staff if severely sensitive.
