A gluten free loose leaf tea guarantee across every ingredient on the panel. 135-150mg of natural caffeine per cup, real spices and fruit pieces, and zero wheat-based flavoring shortcuts.
Two things at once: the full-leaf brewing experience most gluten-sensitive tea drinkers can't get from a bagged product, and a confirmed-clean ingredient panel most loose leaf brands don't bother publishing. Every Zest gluten free loose leaf tea uses pure Camellia sinensis leaves, real dried fruit, whole spices, and flower petals. No wheat starch as a bulking agent, no barley malt in the flavor extracts, no rye derivatives anywhere near the blend.
Seven blends, six caffeinated and one caffeine-free for evenings. Every one confirmed gluten free across every ingredient, packed as loose leaf tea rather than compressed into a bag.
The lineup's most-reordered blend, and the one that shows off what the loose leaf format does for a fruity black tea. Orange Pekoe base with hibiscus, cornflower petals, orange peel, and natural passionfruit, orange, and lemon flavors, all confirmed gluten free. 150mg of natural caffeine, brewed hot or cold. Every ingredient on the panel is what it says it is.
The green tea blend gluten-sensitive customers tend to reach for first. Peppermint, pomegranate, lime, safflower, and green tea leaves, no additives that would compromise the gluten free claim. 135mg of natural caffeine, particularly good cold-brewed overnight in a jar.
Açai, strawberry, wild berry, and passionfruit flavoring on a green tea base with safflower petals. Confirmed gluten free at every step of sourcing, from the tea leaves to the fruit pieces to the natural flavor extracts. 135mg of natural caffeine and a profile brighter than most green teas.
Black tea and natural bergamot oil, the two-ingredient blend that answers the gluten question before you even ask it. No barley malt in the bergamot flavoring, no wheat-based emulsifiers holding the flavor together. Just the classic profile at 150mg of natural caffeine.
Real cinnamon chips and apple pieces in a premium black tea base. Both the spice and the fruit sourced with the gluten free guarantee documented at ingredient level. 150mg of natural caffeine, and the warmest option in the gluten free loose leaf lineup.
Cardamom, ginger, cinnamon, cloves, and black tea, gluten free across every spice in the mix. Some chai blends use wheat-based bulking agents to standardize the spice ratio, this one doesn't. 150mg of natural caffeine and a full-leaf spice expansion that a bag simply cannot deliver.
The single caffeine-free option in the gluten free loose leaf range. Organic chamomile and lavender with rose petals, orange peel, and apple pieces, blended with melatonin and L-Theanine. Every botanical is verified gluten free, with none of the wheat-derived thickeners that show up in some flavored sleep teas.
Loose leaf format has its own brewing habits. Four small choices separate a decent cup from the one you actually want to slow down for.
One rounded teaspoon of our gluten free loose leaf tea per six to eight ounces of water is the starting baseline. Denser blends measure heavier by volume than the fluffy greens, so adjust on the second cup once you've seen how a specific blend behaves in your infuser.
Black tea blends want water at 200 to 210°F, just off a rolling boil. Green tea blends prefer 175 to 185°F. The temperature ratio dictates how caffeine and L-Theanine extract into the water, and the flavor follows.
Four to five minutes for the black tea blends, three to four for the greens. Steep time is where most inconsistency lives, and a two-dollar kitchen timer solves it. Set it before you walk away from the mug.
A generous mesh infuser, a French press, or a wide-mouth teapot gives the leaves enough room to expand fully. Full-leaf blends need the surface area to release both the flavor and the caffeine. A cramped strainer wastes both.
Because loose leaf with a gluten free guarantee shouldn't come with a footnote or an ingredient mystery.
Not "made in a gluten free facility." Every ingredient in every one of our gluten free loose leaf tea blends is verified gluten free at source, from the tea leaves to the spices to the natural flavor extracts. One consistent answer across the entire range.
Loose leaf lets the tea expand properly during the steep, which is where the flavor and the caffeine actually live. A pressed tea bag caps that expansion. This range skips the compromise entirely.
Coffee-level caffeine sourced from the Camellia sinensis plant, extracted and blended back into the leaves. Roughly three times what a standard supermarket loose leaf delivers, and none of the synthetic caffeine some brands quietly add.
Non-GMO certified across the ingredient panel of every blend. The natural flavors come from plant sources, the spices come from named origins, and the certification covers everything from the base tea to the smallest fruit piece.
Zero synthetic flavor compounds, zero added sugar, zero calories in the hot brew. The flavor character comes from the ingredients rather than from a lab, and the panel reads short enough to check on a phone screen.
Each 4oz pouch of gluten free loose leaf tea brews approximately 50 cups. A month of daily use with margin for a second cup on the days that ask for one, delivered in one order.
