Do Dunkin Refreshers Have Caffeine? Every Size and Base
Yes. Every Dunkin Refresher contains caffeine from brewed green tea and green tea extract inside the fruit concentrate. According to Dunkin, as reported by Elite Daily and Tasting Table, a small has 66 mg, a medium 99 mg, and a large 132 mg. No standard Refresher is caffeine free, including the lemonade and sparkling versions. Checked against Dunkin's published documents September 19, 2026.
How Much Caffeine Is in a Dunkin Refresher?
A small has 66 mg, a medium has 99 mg, and a large has 132 mg. Those figures come from Dunkin itself, relayed through press coverage at the drink's June 2020 launch and confirmed by Tasting Table in 2025.
| Size | Cup Size (fl oz) | Caffeine (mg) | mg per fl oz (includes ice) | Source |
|---|---|---|---|---|
| Small | 16 | 66 | ~4.1 | Dunkin via Elite Daily, 2020 |
| Medium | 24 | 99 | ~4.1 | Dunkin via Tasting Table, 2025 |
| Large | 32 | 132 | ~4.1 | Dunkin via Tasting Table, 2025 |
Important context: Dunkin's current Nutrition Guide (last updated 08-19-2026) has no caffeine column. Every milligram number online traces back to figures Dunkin gave to reporters, not to a value on Dunkin's site.
Flavor does not change caffeine. According to Tasting Table, a medium Refresher's caffeine comes from both the brewed green tea base and green tea extract in the concentrate. Strawberry Dragonfruit, Mango Pineapple, Black Cherry, Pink Pineapple: same caffeine at a given size.
Does the Dunkin Lemonade Refresher Have Caffeine?
Popular advice says swapping to lemonade removes most or all of the caffeine. Dunkin's own Allergen and Ingredient Guide (updated 08-19-2026) says otherwise. The flavor concentrate lists green tea extract in every Refresher variant listed in the guide.
| Refresher Base | Green Tea Extract in Concentrate? | Brewed Green Tea as Base? | Caffeine Published? |
|---|---|---|---|
| Green Tea (standard) | Yes | Yes | Yes (66 / 99 / 132 mg) |
| Lemonade | Yes | No | No |
| Sparkling | Yes | No | No |
| Oatmilk | Yes | No | No |
| Daydream | Yes | No | No |
| Black Tea | Yes | Yes (brewed iced tea) | No |
| Protein | Yes | No | No |
The lemonade, sparkling, and oatmilk versions skip the brewed green tea, so they likely have less caffeine. But Dunkin publishes no figure for any of them. Treat them as caffeinated.
Where Does the Caffeine in a Dunkin Refresher Come From?
Two places: the brewed green tea base and the green tea extract inside the fruit concentrate. Dunkin's 2020 press release described the drinks as "made with iced green tea, flavored fruit concentrate, and B vitamins." The B vitamins (B3, B5, B6, B12) are not stimulants. All of the caffeine comes from the tea.
Dunkin Refresher Caffeine vs Coffee, Cola, and Other Benchmarks
A medium Refresher sits between a cola and a cup of brewed coffee.
| Drink or Format | Serving Size | Caffeine (mg) | Source |
|---|---|---|---|
| Dunkin Refresher, small | 16 fl oz | 66 | Dunkin via Elite Daily |
| Dunkin Refresher, medium | 24 fl oz | 99 | Dunkin via Tasting Table |
| Dunkin Refresher, large | 32 fl oz | 132 | Dunkin via Tasting Table |
| Brewed coffee | 8 fl oz | ~95 | USDA FoodData Central |
| Coca-Cola | 12 fl oz | 34 | Coca-Cola |
| Dunkin Refreshers Singles To Go | 16.9 fl oz (mixed) | 80 | Dunkin press release |
| Caffeine pouch (not a drink) | 1 pouch | 80 | Roon |
A large Refresher (132 mg) holds more total caffeine than a standard 8 oz cup of brewed coffee, spread across 32 ounces of iced liquid. A medium is roughly one cup's worth.
Is a Dunkin Refresher a Lot of Caffeine?
For most healthy adults, no. The FDA considers 400 mg per day an amount not generally associated with dangerous negative effects. A large (132 mg) is about one third of that limit.
But a few groups should pay closer attention:
- Pregnancy and breastfeeding. The FDA recommends talking to your health care provider about limiting caffeine. Talk to your clinician before counting a Refresher into your daily total.
- Children and teens. The FDA notes that medical experts advise against energy drinks for children and teens. A large Refresher (132 mg) is nearly four times a 12 oz Coca-Cola (34 mg).
- Caffeine-sensitive individuals. If 99 mg hits you hard, that is real. Sensitivity varies by genetics, body weight, and habituation.
- Afternoon orders. A 2013 study (Drake et al., J Clin Sleep Med, n = 12) found 400 mg of caffeine six hours before bed reduced sleep by more than an hour. A large Refresher is a third of that dose, but stacked on morning coffee, the afternoon top-up matters. More on how long caffeine stays in your system.
Anyone on medication, managing a heart condition, or under 18 should talk to a clinician.
How Much Sugar Is in a Dunkin Refresher?
Sugar is where Refreshers really catch you. From Dunkin's Nutrition Guide (updated 08-19-2026):
| Refresher | Small (added sugar) | Medium (added sugar) | Large (added sugar) |
|---|---|---|---|
| Strawberry Dragonfruit, green tea | 18 g | 27 g | 37 g |
| Mango Pineapple, green tea | 19 g | 29 g | 39 g |
| Strawberry Dragonfruit, lemonade | 36 g | 54 g | 72 g |
| Mango Pineapple, lemonade | 38 g | 57 g | 76 g |
The American Heart Association recommends no more than 25 g per day for women and 36 g for men. A medium lemonade Refresher (54 g) blows past both limits in one cup. Even the green tea medium (27 g) exceeds the women's cap. Two mediums is about 200 mg of caffeine and 54 g of added sugar before you eat anything else.
How to Order a Dunkin Refresher with Less Caffeine
Size down. A small is 66 mg versus a large at 132 mg. That one change cuts your dose in half.
Swapping to lemonade removes the brewed green tea, which likely drops caffeine, but the concentrate still has green tea extract and Dunkin publishes no number for these versions. Do not assume zero. If you need a caffeine-free fruity drink, skip the Refresher menu entirely and order a plain lemonade, or check what the store carries without green tea or matcha.
Dunkin Refreshers Singles To Go Caffeine
The retail stick packs are a separate product. Each Dunkin Refreshers Singles To Go stick has 80 mg of caffeine from green tea, mixes with 16.9 fl oz of water, is sugar free, and has 5 calories. That 80 mg lands between a small (66 mg) and a medium (99 mg) in-store Refresher.
Know the Number Before You Order
Dunkin Refreshers are not caffeine free. They are green tea-based drinks with real caffeine: 66 mg small, 99 mg medium, 132 mg large. The lemonade and sparkling versions still contain green tea extract and have no published caffeine figure, so treating them as zero is a gamble. The sugar, especially in lemonade builds, can exceed the AHA's daily limit in a single cup. Check the size, check the base, and check the number.
Frequently Asked Questions
Do Dunkin Refreshers have caffeine?
Yes. Every Refresher contains caffeine from brewed green tea and green tea extract in the concentrate: 66 mg small, 99 mg medium, 132 mg large, per figures Dunkin gave to press outlets at the 2020 launch. Dunkin's Nutrition Guide has no caffeine column.
Which Dunkin Refresher has no caffeine?
None. Every flavor concentrate in Dunkin's Allergen and Ingredient Guide lists green tea extract. Swapping to lemonade removes the brewed tea but not the extract. If you need zero caffeine, skip the Refresher menu.
Does the Strawberry Dragonfruit Refresher have caffeine?
Yes. Same formula as every other flavor: brewed green tea plus a concentrate containing green tea extract. Caffeine is 66 mg (small), 99 mg (medium), or 132 mg (large). Flavor does not change the number.
Do Dunkin Refreshers have more caffeine than iced coffee?
No. According to Tasting Table, a medium Dunkin hot coffee has about 210 mg, more than double a medium Refresher's 99 mg. Refreshers sit closer to one standard 8 oz cup of brewed coffee (~95 mg per USDA data).
Can kids drink Dunkin Refreshers?
The FDA notes that medical experts advise against energy drinks for children and teens. A Refresher is not an energy drink, but a small still has 66 mg of caffeine, roughly twice a 12 oz cola. Talk to your pediatrician.
Will a Dunkin Refresher keep me up at night?
Timing matters. A 2013 study found 400 mg of caffeine six hours before bed reduced sleep by over an hour. A large Refresher is a third of that dose, but stacked on other caffeine it adds up. Finish your last caffeinated drink at least six to eight hours before bed.
If You Wanted the Lift Without the 27 Grams of Sugar
A medium Refresher delivers 99 mg of caffeine with 27 g of added sugar (54 g in the lemonade version), and Dunkin does not print caffeine on its own nutrition guide. You feel the lift but cannot see the dose or the sugar on the label.
Roon is a zero-nicotine oral pouch, not a drink. Each pouch delivers 80 mg caffeine, 60 mg L-theanine, 25 mg methylliberine (Dynamine), and 5 mg theacrine (TeaCrine), with zero sugar, zero calories (sweetened with sucralose), and the dose printed on the tin. Methylliberine slows caffeine clearance: a randomized crossover PK study (n = 12) using 100 mg methylliberine with 150 mg caffeine cut clearance from 41.9 to 17.1 L/hr and extended half-life from 7.2 to 15 hours, with no higher peak. Roon's 25 mg methylliberine with 80 mg caffeine is a fraction of that study dose (4x less methylliberine, ~1.9x less caffeine), so the effect is directionally the same but not identical. The felt window is 6 to 8 hours. Stop at least 8 hours before bed.
Not a Refresher replacement. No fruit, no cold cup. What Roon gives you is a labeled dose, zero sugar, and a longer window. From $9.16 per tin on a 12-tin subscription ($0.61 per pouch) or $15.00 one-time, with a 30-day money-back guarantee on a first order. Try Roon if knowing the number matters more than tasting the fruit.
