This site’s Dunkin’, McDonald’s, Starbucks, and Tim Hortons caffeine breakdowns cover four of the biggest coffee counters in the US, but Panera Bread, whose Sip Club subscription pours coffee and café blend iced coffee, capped at 30 drinks a month since Panera dropped the “unlimited” branding in August 2026, has been missing from that lineup. Panera also happens to be the rare chain that publishes a genuine internal dataset rather than a handful of customer-service estimates: a PDF titled “Panera Bread Beverage Caffeine Content,” effective March 11, 2026 and marked Edition 1, lists a caffeine figure for nearly every drink on the menu, hundreds of line items deep, sizes and flavors included. That recency turns out to matter. Two independent secondary sources, Caffeine Informer and Tasting Table, each measured Panera’s coffee at different points in that document’s recent history, and lining all three up side by side surfaces a genuinely useful story about how much a fast-casual chain’s own coffee math can shift in under a year, not just a simple lookup table.

Panera’s March 2026 guide lists three drip coffee options at the counter, Cafe Blend Light Roast, Cafe Blend Dark Roast, and Hazelnut Flavored Coffee, and states the identical caffeine figure for all three of them at each size.

Size Light Roast Dark Roast Hazelnut Flavored
16 fl oz 189mg 189mg 189mg
20 fl oz 237mg 237mg 237mg
Decaf, 16 fl oz 5mg
Decaf, 20 fl oz 6mg

That flat match across three different roast profiles, light, dark, and a flavored blend, is a cleaner version of a pattern this site’s own roast level guide already explains: roasting drives off moisture and mass rather than caffeine itself, so a darker roast is not a reliable predictor of a weaker or stronger cup. This site’s Tim Hortons breakdown found dark roast running only about 5mg below standard brewed coffee at matching sizes, close but not identical. Panera’s own document goes a step further and reports zero difference at all, at either size, across three separate coffee products. Decaf sits at 5 to 6mg per cup, well inside the 2 to 15mg range this site’s own decaf coffee breakdown documents across other chains.

Espresso and the drinks built on it: shot count sets the number, not cup size

Panera’s guide lists a standalone “Espresso” item at 126mg alongside a separate line for “Additional Shot of Espresso” at 63mg. That makes the standalone Espresso menu item a double shot by default, 2 times 63mg, and it explains why every espresso-based drink on the menu carries the identical 126mg regardless of size:

Drink 16 fl oz 20 fl oz
Americano 126mg not listed
Caffe Latte 126mg 126mg
Cappuccino 126mg 126mg
Caramel Latte 126mg 126mg
Madagascar Vanilla Latte 126mg 126mg
Mocha Latte 134mg 137mg

Ordering a bigger latte at Panera buys more milk, not more caffeine, since every size runs on the same fixed double shot. Mocha Latte is the one exception, 134mg at 16oz and 137mg at 20oz, a few extra milligrams that likely come from the chocolate sauce itself rather than the espresso base, though Panera’s document does not spell out the mechanism and this site could not independently confirm it, so take that as a reasonable inference rather than a sourced fact.

Iced coffee: why “no ice” nearly doubles the caffeine in the same size cup

The most actionable number in the entire document is the one most people never think to ask about. Panera’s guide lists Iced Cafe Blend Dark Roast Coffee twice at each size, once as normally served with ice, once specified “no ice,” and the gap between the two is enormous:

Data: Panera's own March 2026 Beverage Caffeine Content guide, cited in this article
Size With ice No ice
20 fl oz 102mg 186mg
30 fl oz 166mg 279mg

Asking for no ice in the same cup size, per Panera’s own figures, adds 84mg at 20oz and 113mg at 30oz, roughly a 68 to 82 percent increase in caffeine for the identical drink and the identical price. The mechanism is straightforward once the two numbers are sitting next to each other: a cup filled mostly with ice holds less actual coffee than a cup filled to the same line with almost none, so the caffeine concentration per ounce of liquid coffee stays constant while the finished-cup total swings hard depending on how much of that cup is ice rather than drink. No other single ordering choice on this page moves the number by anywhere near that much.

What changed since the last time anyone else measured this

Tasting Table published its own Panera caffeine breakdown on April 29, 2025, and its figures do not match the March 2026 official document at several points, not because either source is wrong, but because Panera’s own menu appears to have changed in between. Tasting Table measured drip coffee at 12 fl oz, a size that does not appear anywhere in the current official guide, which lists only 16 and 20 fl oz cups: 230mg for Café Blend Light Roast, 161mg for Café Blend Dark Roast, and 209mg for Hazelnut Coffee at that now-discontinued size. Even accounting for the smaller cup, the new 16oz figure of 189mg for Light Roast is lower than what Tasting Table reported for a 12oz Light Roast a year earlier, a genuine drop rather than a rounding difference. Tasting Table also reported a 16oz Caffè Latte at 145mg and a single espresso shot at 73mg, both above the current official figures of 126mg and 63mg respectively.

Caffeine Informer’s page tracks much closer to the new document at the coffee counter, 189mg and 236mg at 16 and 20oz against the official 189mg and 237mg, essentially an exact match, but it still lists a 12oz “Small” figure of 142mg that has no equivalent anywhere in the current guide, and its lattes are listed at 179mg rather than the official 126mg. That mixed pattern, some numbers freshly updated, others carried over from an older menu, is the clearest sign that a third-party aggregator page can be partially current and partially stale at the same time, which is exactly why this page leads with Panera’s own dated document rather than either secondary source alone.

The most consequential menu change is not a mislabeled number at all. Panera pulled its Charged Lemonade line entirely, and the current caffeine guide does not list a single Charged product anywhere. The Center for Science in the Public Interest reported the drinks ranged from 155 to 178mg in a 20oz regular size and 233 to 302mg in a 30oz large across three flavors, and that Panera removed the line nationwide following two lawsuits alleging the beverages caused the deaths of a 21-year-old woman and a 46-year-old man who were not aware they were consuming that much caffeine in what was marketed as a lemonade. Caffeine Informer’s own older page still lists higher figures for the same drinks, 260mg and 390mg, a reminder that even the caffeine content of a since-discontinued product was never fully settled across sources before it disappeared from the menu.

One more genuine gap is worth naming plainly rather than papering over: Cold Brew does not appear anywhere in the March 2026 caffeine document, even though Panera’s own site still lists active product pages for Cold Brew, Frozen Chocolate Cold Brew, Frozen Caramel Cold Brew, and multiple Madagascar Vanilla Cold Brew variations. That looks like an omission in the caffeine guide rather than evidence the drink was pulled. Until Panera’s own document catches up, Tasting Table’s figure, 162mg in a 16oz cup, is the best sourced number available.

Worked example: reading your own Panera order against the official guide

  1. Check your cup size before assuming a number. Panera’s current menu runs 16 and 20 fl oz for hot drinks and 20 and 30 fl oz for iced, not the 12oz size some older write-ups still reference.
  2. Do not expect roast level to change your dose. Light Roast, Dark Roast, and Hazelnut Flavored Coffee all carry the identical 189mg at 16oz and 237mg at 20oz, per Panera’s own document, so pick a roast for flavor, not caffeine.
  3. Treat every espresso drink at a given size the same. Latte, cappuccino, caramel latte, and vanilla latte all run 126mg regardless of 16 or 20oz, since the size upcharge is milk, not espresso.
  4. Decide on ice before you decide on size. A 20oz iced coffee with no ice carries 186mg, close to a full 20oz hot coffee’s 189mg, while the same cup with a normal fill of ice drops to 102mg. If the goal is a specific caffeine target, that choice matters more than picking between 20 and 30oz.
  5. Cross-check your daily total against 400mg. MD Anderson Cancer Center cites the FDA’s general guidance that “most adults can consume about 400 milligrams of caffeine per day without negative effects.” A single 20oz no-ice iced coffee already covers close to half that budget on its own.

How Panera stacks up against Dunkin’, Starbucks, McDonald’s, and Tim Hortons

Comparing chains fairly means comparing caffeine per fluid ounce, since a “medium” or a 16oz cup is not the same pour everywhere. Panera’s 189mg in a 16oz coffee works out to about 11.8mg per fl oz.

Chain Size Caffeine Per fl oz
McDonald’s 16 fl oz 145mg About 9.1mg
Panera 16 fl oz 189mg About 11.8mg
Tim Hortons 14 fl oz 205mg About 14.6mg
Dunkin’ 14 fl oz 210mg 15.0mg
Starbucks (Grande Pike Place) 16 fl oz 310mg About 19.4mg

Panera lands ahead of McDonald’s but behind Tim Hortons, Dunkin’, and Starbucks per ounce, a middle-of-the-pack result for a chain that is not primarily marketed as a coffee shop the way the other four are.

Common mistakes

Assuming a darker roast means a bigger jolt is the most common mistake on this page; Panera’s own document reports zero difference between Light Roast, Dark Roast, and Hazelnut Flavored Coffee at either size it sells. Assuming a bigger cup buys more caffeine in an espresso drink is the second mistake; every latte, cappuccino, and caramel latte on the menu carries the same 126mg at 16 and 20oz, since size only changes the milk. Treating an older write-up’s 12oz figures as current is the third mistake; Panera’s own March 2026 guide only lists 16 and 20oz cups, and the per-cup numbers genuinely moved between the two size structures, not just the arithmetic. Ordering iced coffee without specifying ice level and expecting a predictable dose is the fourth mistake; per Panera’s own figures, “no ice” nearly doubles the caffeine in the same size cup compared with a normal ice fill.

Common questions

How much caffeine is in a Panera coffee? 189mg in a 16 fl oz cup and 237mg in a 20 fl oz cup, per Panera’s own March 2026 Beverage Caffeine Content guide, and that figure is identical across Light Roast, Dark Roast, and Hazelnut Flavored Coffee.

Does Panera publish its own caffeine data? Yes. A dated, edition-numbered PDF covers essentially the entire beverage menu, a genuine company-sourced dataset rather than a customer-service estimate, though the company itself labels every figure “an approximate value.”

Does roast level change how much caffeine is in Panera coffee? No. Panera’s own document lists the identical 189mg (16oz) and 237mg (20oz) figures for Light Roast, Dark Roast, and Hazelnut Flavored Coffee, a cleaner version of the same pattern this site’s roast level guide documents at other chains.

How much caffeine is in a Panera latte or cappuccino? 126mg, per Panera’s current guide, and that number does not change between 16 and 20oz, since every size uses the same double-shot espresso base and only adds more milk.

Does asking for no ice really change the caffeine in iced coffee? Substantially, per Panera’s own figures: a 20oz Iced Cafe Blend Dark Roast Coffee carries 102mg with a normal ice fill versus 186mg with no ice, and a 30oz carries 166mg versus 279mg, since less ice means more actual coffee fits in the same cup.

What happened to Panera’s Charged Lemonade, and how much caffeine did it have? Panera discontinued Charged Lemonade nationwide after two lawsuits alleged the drinks, which ran 155 to 302mg of caffeine depending on size and flavor per the Center for Science in the Public Interest, contributed to two deaths among people unaware of how much caffeine they were drinking. The product no longer appears anywhere in Panera’s current beverage caffeine guide.
