Check price →Read review ↓Numi Organic Tea is the brand you reach for when you care where your tea comes from. Founded in Oakland by a brother-and-sister team, it has spent two decades building a reputation on three pillars: 100% organic ingredients, genuinely plastic-free tea bags, and fair-trade, transparently sourced herbs. The boxes are recyclable, the bags are unbleached and unsealed with plastic, and the company is a certified B Corporation. On paper, it's about as conscientious as a tea brand gets. The question this review answers is whether all that virtue shows up in the cup.
The short answer: yes, more often than not. After brewing Numi's Aged Earl Grey, Gunpowder Green, and Turmeric Three Roots, our verdict is that Numi delivers a clean, honest, single-origin-quality cup that comfortably beats supermarket bags on both flavor and sourcing integrity — and the eco claims are real, third-party-verified, not greenwashing. Where it stumbles is consistency across the range (the herbal-functional blends are hit-or-miss) and value, since you're paying a premium that's easier to justify for the sourcing than for the raw flavor versus a few loose-leaf rivals.
Below we give the bottom line first, then a comparison table, then a tea-by-tea breakdown including what we'd skip. We bought these teas at retail and accept no payment for placement. Affiliate links help fund the testing but never decide the verdict — that's the whole point of doing this independently.
The short version
- Numi's eco credentials are real and verifiable: it's a Certified B Corporation, its tea bags are genuinely plastic-free (unbleached filter paper with no polypropylene seal), and 100% of its teas are certified organic and non-GMO Project verified.
- The best cup in the lineup is Gunpowder Green — a clean, full-bodied, slightly smoky green that's forgiving to brew and the clearest demonstration of Numi's sourcing quality at a reasonable per-cup cost.
- Aged Earl Grey is a genuinely distinctive Earl Grey, using bergamot-scented tea that's been aged for a deeper, mellower citrus rather than the sharp synthetic bergamot of cheap versions.
- Turmeric Three Roots is the most polarizing: a bold, peppery, earthy blend of turmeric, ginger, and licorice that some love and others find medicinal — and the per-bag curcumin dose is modest, so treat it as a warming cup, not a supplement.
- You're paying roughly 30 to 45 cents per bag, about 2 to 3x a basic store brand. The premium is well justified by sourcing ethics and clean flavor; it's harder to justify purely on taste against the best loose-leaf competitors.

Best Overall
Numi Organic Tea Gunpowder Green (18 Tea Bags)
A clean, full-bodied gunpowder green with a gentle smoky depth that's the easiest Numi tea to recommend.
Origin & grade: Certified organic and Non-GMO Project Verified; rolled green tea leaves sourced through Numi's transparent, fair-labor supply program. Plastic-free, unbleached tea bag.
Gunpowder green is one of the smartest formats in tea: rolling the leaves into dense pellets shields them from air and light, so the tea stays fresher and steeps into something fuller and rounder than loose, flat green tea. Numi's version delivers exactly that — a cup with real body, a clean vegetal backbone, and a faint smoky note that gives it character without tipping into the burnt, acrid territory that ruins lower-grade gunpowder.
What stands out is how forgiving it is. Green tea is notoriously easy to wreck with water that's too hot or a steep that runs too long, turning the cup bitter and astringent. Numi's gunpowder tolerates a wider margin. We brewed it at the recommended temperature and time, then deliberately pushed both, and it stayed drinkable where a cheaper green would have gone harsh.
Brew with water just off the boil (around 175°F / 80°C) for 2 to 3 minutes for the cleanest cup. It re-steeps well — the pellets have more to give on a second infusion — which improves the real cost-per-cup. This is the blend that best justifies Numi's price.
- Caffeine
- Medium (roughly 25–35 mg per cup)
- Bags per box
- 18, plastic-free unbleached bags
- Tea type
- Rolled gunpowder green tea
- Certification
- Organic; Non-GMO Project Verified; B Corp
- Steep
- 2–3 min at ~175°F / 80°C
What we like
- Full-bodied and clean with a pleasant smoky depth
- Forgiving — resists bitterness if slightly over-steeped
- Re-steeps well, improving cost-per-cup
- Genuinely plastic-free, organic, and B Corp sourced
Worth noting
- Smoky style won't suit fans of bright grassy greens
- Still costs more than a basic supermarket green tea
Who should buy it: Everyday green tea drinkers who want a cleaner, fuller cup than supermarket green bags, and anyone who finds plain green tea too bitter or grassy.
What we don't like: It's still a smoky-leaning green — if you prefer the bright, grassy, almost sweet profile of a sencha or a Japanese green, this rounder, smokier style won't be your favorite.
Bottom line: If you buy one Numi tea, make it this one. Gunpowder green is tea that's been rolled into tight pellets, which protects the leaf and unfurls into a surprisingly full, slightly smoky cup. Numi's version is clean and well-made, with none of the dusty, grassy bitterness that cheap green bags suffer from. It's forgiving — it won't turn punishingly astringent if you slightly over-steep — and it shows off exactly what the brand's organic sourcing buys you: a cup that tastes like real, fresh leaf.
02 · Best for Earl Grey drinkers who want real bergamot depth
Best Black Tea
Numi Organic Tea Aged Earl Grey (18 Tea Bags)
A mellow, deep Earl Grey using aged bergamot-scented black tea instead of sharp synthetic citrus.
Origin & grade: Certified organic and Non-GMO Project Verified; organic black tea scented with real bergamot and aged before packing. Plastic-free, unbleached tea bag.
Earl Grey lives or dies on its bergamot, and most mass-market versions lean on a loud, slightly synthetic citrus oil that sits on top of a forgettable black base. Numi's approach is different: it scents an organic black tea with real bergamot and then ages the tea, letting the citrus marry into the leaf rather than perch on top of it. The cup that results is mellower, deeper, and more cohesive — the bergamot reads as warmth and aroma woven through the tea rather than a sharp note bolted on.
The black tea base itself is solid: brisk but not harsh, with enough malt and body to take milk if you want it, though we preferred this one black to let the aged bergamot show. It's a noticeably more grown-up Earl Grey than the supermarket standard.
Steep 3 to 4 minutes in freshly boiled water. Because the bergamot is mellow rather than aggressive, this Earl Grey rewards a slightly longer steep than you'd give a sharper version. Excellent plain; pleasant with a splash of milk.
- Caffeine
- Medium-high (black tea base, roughly 40–50 mg per cup)
- Bags per box
- 18, plastic-free unbleached bags
- Tea type
- Bergamot-scented aged black tea
- Certification
- Organic; Non-GMO Project Verified; B Corp
- Steep
- 3–4 min at boiling (~212°F / 100°C)
What we like
- Mellow, integrated bergamot from real citrus, not synthetic
- Solid malty black base that takes milk well
- Aging gives a deeper, more cohesive cup
- Organic, plastic-free, ethically sourced
Worth noting
- Too understated for fans of sharp, punchy bergamot
- Higher caffeine — not an evening tea
Who should buy it: Earl Grey drinkers who find typical versions too sharp or synthetic, and anyone who wants a deeper, more integrated, organic take on the classic.
What we don't like: If you love the bright, almost perfumey bergamot punch of a classic Earl Grey, Numi's aged, mellowed style may read as too restrained or subtle.
Bottom line: This is a thinking person's Earl Grey. Instead of dosing a cheap black base with a punchy, almost perfumey synthetic bergamot, Numi scents organic black tea with real bergamot and ages it, which rounds the citrus into something deeper and mellower. The result is less of an upfront citrus slap and more of an integrated, aromatic cup. Earl Grey purists who find most versions too sharp will appreciate it; anyone craving that bright, in-your-face bergamot zing may find it understated.
03 · Best for a bold, warming, caffeine-free root blend
Best Functional Blend
Numi Organic Tea Turmeric Three Roots (12 Tea Bags)
A bold, peppery turmeric-ginger-licorice blend that's warming and assertive — and not for everyone.
Origin & grade: Certified organic and Non-GMO Project Verified; turmeric, ginger, and licorice root with black pepper, sourced through Numi's fair-labor program. Plastic-free, unbleached tea bag.
Where many turmeric teas play it safe with citrus and sweeteners, Numi commits to the roots. Turmeric, ginger, and licorice form the backbone, with a deliberate hit of black pepper. The result is bold and unapologetically earthy: warming ginger heat up front, deep turmeric in the middle, and a lingering natural sweetness from the licorice that means you genuinely don't need to add anything. The black pepper isn't just for flavor — piperine in pepper is traditionally paired with turmeric — and it gives the cup a subtle peppery lift.
This is a tea with a strong point of view, and that's exactly why it's polarizing. If you find most turmeric teas too timid, this will be a revelation. If you wanted something soft and approachable, the licorice sweetness and root intensity can read as medicinal.
Steep a full 5 to 6 minutes in boiling water to pull the most from the roots — this is one blend where under-steeping leaves flavor on the table. Caffeine-free, so it works any time of day. A note for some drinkers: licorice root in large daily quantities is not appropriate for everyone (for example, those managing blood pressure), so if that applies to you, check with a clinician before making it a daily habit.
- Caffeine
- None (caffeine-free herbal)
- Bags per box
- 12, plastic-free unbleached bags
- Key ingredients
- Turmeric, ginger, licorice root, black pepper
- Certification
- Organic; Non-GMO Project Verified; B Corp
- Steep
- 5–6 min at boiling (~212°F / 100°C)
What we like
- Bold, warming, genuinely spicy turmeric-ginger flavor
- Naturally sweet from licorice — no sweetener needed
- Caffeine-free, drinkable any time of day
- Organic, plastic-free, ethically sourced roots
Worth noting
- Polarizing — can read as medicinal or too sweet
- Modest curcumin; not a supplement dose
- Licorice not suitable for everyone in daily amounts
Who should buy it: People who want a bold, genuinely spicy, caffeine-free turmeric-and-ginger cup and find most golden teas too mild or sweet.
What we don't like: It's assertive to the point of medicinal for some palates; the licorice makes it quite sweet; and like all turmeric teas, a single bag's curcumin dose is too small to lean on for any health purpose.
Bottom line: Turmeric Three Roots is the most divisive tea in this review. It's a robust, no-holds-barred root blend — turmeric, ginger, and licorice, lifted by black pepper — that drinks earthy, spicy, and naturally sweet from the licorice. People who want a serious, warming turmeric cup will love how assertive it is; people expecting a soft, mild golden tea may find it medicinal and heavy. As with any turmeric tea, the curcumin per bag is modest, so enjoy it as a flavorful, warming infusion rather than a wellness dose.
Key terms
- Certified B Corporation
- An independent certification (from the nonprofit B Lab) auditing a company's social and environmental performance, accountability, and transparency. Numi is a certified B Corp, so its ethics claims are externally verified, not self-declared.
- Plastic-free tea bag
- A tea bag made without the polypropylene seal or mesh used in many conventional bags. Numi uses unbleached filter paper without plastic sealant, which avoids shedding microplastics into hot water.
- Non-GMO Project Verified
- A third-party certification confirming a product is made without genetically modified organisms, following the Non-GMO Project's standard. All Numi teas carry it.
- Gunpowder green
- A style of green tea in which leaves are rolled into tight pellets that resemble gunpowder. The rolling protects the leaf from air and light, yielding a fuller, fresher, slightly smoky cup that's more forgiving to brew.
- Curcumin
- The headline compound in turmeric. A single tea bag delivers only a small amount, which is why turmeric tea is a flavorful warming cup rather than a meaningful supplement dose.
Questions, answered
Are Numi tea bags actually plastic-free?
Yes. Numi's tea bags are made from unbleached filter paper without the polypropylene seal or mesh found in many conventional bags. That's a meaningful difference, because plastic-sealed bags can shed microplastics into hot water. Numi's plastic-free construction is one of the brand's central, verifiable selling points.
Is Numi tea certified organic?
Yes. 100% of Numi's teas are certified organic, and the brand is also Non-GMO Project Verified. The herbs and tea leaves are grown without synthetic pesticides or fertilizers, and these are independently audited certifications rather than self-applied labels, so the claims are verifiable.
Is Numi a B Corp?
Yes. Numi Organic Tea is a Certified B Corporation, meaning an independent body (B Lab) has audited its social and environmental performance, accountability, and transparency. This is why Numi's ethical and sustainability claims carry more weight than a typical self-declared 'eco' label.
Does Numi Turmeric Three Roots have health benefits?
Turmeric, ginger, and licorice have long histories in traditional wellness practice and may support digestive comfort, but a single tea bag delivers only a modest amount of curcumin — far less than a turmeric supplement. Treat it as a warming, flavorful cup rather than a medicine. Also note that licorice root in large daily amounts isn't appropriate for everyone, including some people managing blood pressure, so check with a clinician if that applies to you.
How is Numi's Aged Earl Grey different from a normal Earl Grey?
Most Earl Grey leans on a sharp, sometimes synthetic bergamot oil over a basic black base. Numi scents an organic black tea with real bergamot and then ages it, which lets the citrus marry into the leaf. The result is mellower, deeper, and more integrated — less of an upfront citrus punch and more of an aromatic, cohesive cup. Purists who find typical Earl Grey too sharp tend to prefer it.
Is Numi tea worth the higher price?
For the cup and the sourcing, generally yes. Numi's teas taste cleaner than supermarket bags and the eco credentials — B Corp, organic, plastic-free — are real and verifiable. At roughly 30 to 45 cents a bag versus 10 to 15 cents for a basic store brand, you're paying 2 to 3x. The premium is well justified by sourcing ethics and clean flavor; it's harder to justify on taste alone against the best loose-leaf specialists.
Which Numi tea has the most caffeine?
Among these three, the Aged Earl Grey has the most caffeine, since it's a black tea (roughly 40 to 50 mg per cup). Gunpowder Green sits in the medium range (about 25 to 35 mg), and Turmeric Three Roots is completely caffeine-free, making it the best option for the evening.
Can you re-steep Numi tea bags?
Some hold up better than others. The Gunpowder Green re-steeps particularly well — the rolled pellets release more flavor on a second infusion, which improves the real cost-per-cup. The Aged Earl Grey gives a lighter but still pleasant second cup, while herbal-root blends like Turmeric Three Roots are best enjoyed in a single, longer steep.
