The Secret Sweet Spice in Constant Comment Tea Revealed

You know the moment. You tear open the foil pouch, and that smell hits you — orange, warm, something vaguely like a holiday baking aisle. You take the first sip and there it is again: a sweetness that has no business being there, because there’s no sugar in the tea. For decades, people have guessed cinnamon. Some say nutmeg. A few swear it’s allspice.

Here’s the truth: the secret sweet spice in Constant Comment tea is clove, working alongside orange oil to create a flavor profile that tricks your brain into tasting sugar where none exists. This article walks through the chemistry behind that illusion, the history of the 1945 recipe, how to brew it so the sweetness actually shows up, and why every copycat recipe falls short. You’ll leave with a concrete answer, a brewing method that changes the flavor, and a clear picture of what makes this blend genuinely unusual.

If you want to taste the blend while you read, grab a box of Bigelow Constant Comment Caffeinated Black Tea Bags, 20 Count (Pack of 6). It’s the same recipe Ruth Campbell Bigelow first sold in 1945, and the individually wrapped foil pouches keep the orange oil from going stale — which matters more than you’d think, since volatile citrus compounds fade fast once exposed to air.

The Verdict: It’s Not Cinnamon, It’s Clove and Orange

Ask ten people what makes Constant Comment taste sweet, and eight will say cinnamon. They’re wrong, and the mistake makes sense. Cinnamon and clove share a key chemical compound, and your palate reads them similarly. But the actual ingredient list on a box of Bigelow Constant Comment tells a different story: black tea, orange rind, and “natural spices.” The dominant spice in that blend is clove.

Clove carries a compound called eugenol, which is responsible for that numbing, warming, almost sweet sensation on your tongue. Cinnamon has cinnamaldehyde, which is sharper and hotter. The two are often paired in baking, so most people associate that warm sweetness with cinnamon. But clove’s eugenol is the one doing the heavy lifting here, and it’s amplified by the orange oil.

So when someone tells you the secret is cinnamon, they’re not lying — they’re just describing the sensation without naming the actual molecule behind it. The sweet spice is clove. The citrus is orange oil. Together, they create a flavor that reads as “spiced orange dessert” rather than “tea with stuff in it.”

The Chemistry of ‘Sweet’: Eugenol and the Sensory Illusion

The sweetness in Constant Comment isn’t sugar. It’s a chemical trick your brain plays on itself, and understanding it changes how you brew the tea.

Why Your Brain Confuses Clove for Cinnamon

Eugenol is a phenolic compound. It binds to the same heat receptors on your tongue that capsaicin (from chili peppers) activates, but it does so far more gently. That mild warmth creates a tactile sensation that your brain interprets as sweetness, especially when paired with citrus acids. The orange oil provides the acidity; the eugenol provides the warmth; your brain fills in the sugar.

This is why the tea tastes sweet without any caloric sweetener. It’s also why people who add sugar to Constant Comment often find it cloying — the tea already signals sweetness, and added sugar pushes it over the edge. If you’ve been adding sweetener out of habit, try a cup without it. The eugenol is doing more work than you realize.

One professional habit worth adopting: smell the dry leaves before brewing. The eugenol in clove is highly volatile, and you’ll catch a distinct, almost medicinal clove note in the dry tea that disappears once hot water hits it. If you can smell it dry, you know the blend is fresh.

The Role of Orange Oil (Not Peel) in the Blend

Bigelow uses orange oil, not dried orange peel, and the difference matters. Dried peel adds texture and a slightly bitter, woody note. Orange oil delivers a bright, concentrated citrus aroma without any of the fibrous bitterness. It’s the difference between zesting a fresh orange and chewing on a piece of dried rind.

Oil also gives the flavor consistency. A batch of tea made with dried peel varies depending on the harvest, the drying method, and how long the peel sat on a shelf. Oil can be standardized, measured precisely, and blended to the same profile every single time. That consistency is why a box of Constant Comment from 2026 tastes essentially identical to one from 1994.

The trade-off: oil is more volatile than dried peel. It fades faster once the foil pouch is opened. That’s why Bigelow wraps each bag individually — not for convenience, but to keep the orange oil locked in until you’re ready to brew.

The 1945 Origin: Ruth Campbell Bigelow’s Kitchen Experiment

Ruth Campbell Bigelow was not a tea company executive. She was a New York City housewife who ran a small antiques shop and served tea to her customers. In 1945, she decided the standard black tea of the era was dull, so she started experimenting in her kitchen, blending orange rind and spices into strong black tea.

The story goes that her customers kept asking for more of “that constant comment tea” — the phrase she used to describe the steady stream of compliments the blend received. She named the tea after that reaction, and it became the first product of the Bigelow Tea Company.

What’s less known: Ruth’s original recipe used whole spices and orange peel, and she brewed it in large batches. The modern version uses oil and a proprietary spice blend, but the core idea remains unchanged. Black tea, orange, and clove. That’s the whole trick.

The blend’s longevity isn’t an accident. It’s a formula that works because the three components hit different parts of your palate. Black tea provides the bitter backbone. Orange oil provides the bright acidic top note. Clove provides the warm, sweet middle. Remove any one of them, and the tea falls flat.

Brewing the Perfect Cup: Getting the Sweet Spice to Show Up

Here’s where most people go wrong. They brew Constant Comment like any other black tea — boiling water, three minutes, done. That works, but it doesn’t let the eugenol shine. The sweet spice needs slightly cooler water and a slightly longer steep to come forward.

Water Temperature and Steeping Time

Use water at 200°F (93°C), not a rolling boil. Boiling water scorches the orange oil, turning it bitter and flat. 200°F extracts the black tea tannins without destroying the volatile citrus compounds. If you don’t have a thermometer, boil the water and let it sit for 30 seconds before pouring.

Steep for 4 minutes, not 3. The extra minute gives the clove eugenol time to dissolve into the water. At 3 minutes, you get mostly orange and tannin. At 4 minutes, the sweet spice arrives. At 5 minutes, the tea turns bitter and the clove gets medicinal. Four is the sweet spot.

One caveat: this timing works for the caffeinated version. The decaffeinated blend uses a different base tea and needs 5 minutes to reach the same flavor intensity, because the decaffeination process strips some of the aromatic compounds.

The Cold Brew Method for a Sweeter Profile

Cold brewing changes the game entirely. When you steep tea in cold water for an extended period, you extract fewer tannins and more of the aromatic compounds. The result is a cup that tastes noticeably sweeter, with the clove note front and center.

Here’s the method: put two tea bags in a quart jar of cold water. Seal it and refrigerate for 12 hours. Remove the bags and drink. That’s it. No heat, no timing stress, no bitterness.

The cold brew version tastes like a spiced orange iced tea with almost no astringency. It’s a different drink than the hot version, and it’s worth trying at least once. The eugenol behaves differently in cold water — it’s less warming and more fragrant, closer to how clove smells than how it tastes.

If you’re new to cold brewing and want to experiment with other teas, a tea ball infuser makes the process easier for loose-leaf blends, though the bagged version works fine as-is.

The ‘Constant Comment’ vs. ‘Earl Grey’ Confusion

People mix these two up constantly, and it’s easy to see why. Both are black teas with citrus. But they’re structurally different in a way that matters for your taste buds.

Earl Grey uses bergamot oil, a citrus fruit that’s a hybrid of bitter orange and lemon. Bergamot is sharp, floral, and slightly bitter. It sits on top of the tea like a perfume. Constant Comment uses sweet orange oil and clove. The orange is rounder and sweeter, and the clove adds a warmth that bergamot doesn’t have.

The practical difference: Earl Grey is a tea with a flavor added. Constant Comment is a blend where the spices and tea are meant to be tasted together. Earl Grey hits you immediately and fades. Constant Comment builds slowly, with the clove lingering on the finish.

If you like one, you’ll probably like the other, but they scratch different itches. Earl Grey is for when you want something bright and assertive. Constant Comment is for when you want something warm and comforting. If you’re trying to decide which to buy, ask yourself whether you want floral or spicy. That’s the real fork in the road.

The Proprietary Mystery: Why Copycats Fail

Every few years, someone posts a “Constant Comment copycat recipe” online. They all follow the same pattern: black tea, orange peel, cloves, cinnamon. And they all taste wrong. Not bad — just wrong. They’re missing something, and it’s not a secret ingredient. It’s precision.

The Bigelow family has never published the exact proportions of the spice blend, and they’re unlikely to. The recipe is a trade secret, held by a company that’s still 100% family-owned. But the real reason copycats fail isn’t secrecy — it’s that the blend is balanced to work with a specific black tea base, and that base tea has changed over the decades.

Ruth’s original tea used a strong Ceylon black tea. The modern version uses a blend of black teas chosen for consistency. If you use a different black tea — a malty Assam, a floral Darjeeling — the spices hit differently. The clove overwhelms a delicate tea. The orange gets lost in a heavy one. The proportions that work for Bigelow’s base tea don’t translate to whatever you have in your pantry.

There’s also the matter of the oil. Home recipes use dried orange peel, which, as we covered, is a different ingredient. You can’t replicate the bright, clean citrus note of orange oil with dried peel. You can get close, but close isn’t the same.

So the mystery isn’t really about a hidden spice. It’s about a company that spent decades dialing in a specific ratio of tea, oil, and clove, and then never changed it. That’s not a secret you can reverse-engineer from a box of tea.

Frequently Asked Questions

Does it contain sugar?

No. The tea is calorie-free and sugar-free. The sweetness you taste comes from eugenol in the clove, which activates warmth receptors on your tongue that your brain interprets as sweetness. There’s no added sugar, no artificial sweetener, and no honey in the blend.

Is it caffeinated?

Yes, the standard version contains caffeine because it’s made with black tea. A typical cup has roughly 40-60 milligrams of caffeine, comparable to other black teas. Bigelow also makes a decaffeinated version if you want the flavor without the stimulant.

Is it gluten-free?

Yes. The tea and the spices are naturally gluten-free, and Bigelow states the product is gluten-free. The tea bags are also Kosher certified. If you have celiac disease or a gluten sensitivity, this tea is safe to drink.

Can I drink it iced?

Absolutely. The cold brew method described above produces a notably sweeter, smoother iced tea than hot-brewing and pouring over ice. Use two bags per quart of water, refrigerate for 12 hours, and skip the sweetener. The clove note is more fragrant and less warming when cold.

Why does my cup taste bitter sometimes?

You’re likely steeping too long or using water that’s too hot. Boiling water scorches the orange oil, and steeping past 5 minutes extracts excess tannins from the black tea. Use 200°F water and a 4-minute steep. If it’s still bitter, your water might be too hard — mineral-heavy water can make black tea taste harsh.

What to Remember When You Brew Your Next Cup

• The sweet spice is clove, not cinnamon. Eugenol in clove creates the sugar-free sweetness.
• Bigelow uses orange oil, not dried peel. That’s why the citrus is bright, not bitter.
• Steep at 200°F for 4 minutes. Boiling water ruins the orange oil.
• Cold brew for 12 hours for a noticeably sweeter, smoother cup.
• Earl Grey is bergamot and floral; Constant Comment is orange and clove. They’re not interchangeable.
• Copycat recipes fail because they use dried peel and the wrong black tea base. The proportions are proprietary for a reason.
• Skip the sugar. The tea already tastes sweet, and added sugar makes it cloying.
