McDonald’s Served Coffee at 82°C, Led to $600K Lawsuit

In 1994, 79-year-old Stella Liebeck ordered a 49-cent cup of coffee from a McDonald’s drive-thru in Albuquerque, New Mexico. As she tried to add cream and sugar, the cup tipped over in her lap, spilling scalding liquid onto her thighs and groin. What followed wasn’t just a minor accident—it became one of the most infamous personal injury cases in U.S. legal history.

The short answer: McDonald’s served coffee at 82–86°C—far hotter than home-brewed coffee (70–75°C) or even Starbucks. That extreme heat caused third-degree burns on 6% of Liebeck’s body, requiring skin grafts and an 8-day hospital stay. The jury awarded her $200,000 in compensatory damages (reduced to $160,000 due to her 20% fault) and $2.7 million in punitive damages (later settled for around $600,000). The case forced global fast-food chains to rethink coffee serving temperatures.

What Really Happened to Stella Liebeck?

On a chilly morning in Albuquerque, Stella Liebeck, a retired department store clerk, was in the passenger seat of her grandson’s Ford Probe. They’d stopped at a McDonald’s drive-thru and ordered a cup of coffee priced at just 49 cents. Liebeck asked her grandson to pull over so she could add milk and sugar. As the car stopped, she accidentally spilled the entire cup of coffee onto her lap. The coffee was not just hot—it was dangerously so. Liebeck, wearing thin cotton slacks, suffered third-degree burns over 6% of her body, including her thighs and groin, and lesser burns over 16%. She was hospitalized for eight days, underwent multiple skin graft surgeries, and lost 20 pounds (down to 38 kg). Her recovery took two years.

Why Was McDonald’s Coffee So Much Hotter?

Investigation revealed that McDonald’s coffee was served at 82–86°C (180–187°F), significantly hotter than coffee typically brewed and served at home (70–75°C) or even at Starbucks. When questioned in court, McDonald’s quality assurance manager testified that the company kept coffee at this temperature because coffee experts said 96°C water was ideal for brewing, and 82–86°C was the optimal drinking range. However, when pressed by plaintiff’s attorney Reed Morgan, McDonald’s admitted it had never consulted burn specialists about the risks of serving coffee at such high temperatures. Burn experts testified that liquids at 82–86°C can cause third-degree burns in just 2–7 seconds of skin contact. The temperature was not only unnecessary for taste but posed a clear risk to consumers.

The Legal Battle: From Dismissal to Landmark Verdict

Liebeck’s family initially asked McDonald’s to cover her medical expenses, estimated at $20,000. McDonald’s offered just $800. Frustrated, Liebeck’s daughter sought legal help from Texas-based attorney Reed Morgan, who specialized in product liability. The lawsuit filed in New Mexico alleged that McDonald’s coffee was defective, unreasonably dangerous, and lacked adequate warnings. Public and media reaction was initially skeptical, with many mocking the case as frivolous. But during the August 1994 trial, evidence painted a different picture. Morgan presented medical records, burn photos, and expert testimony. He highlighted that McDonald’s sold 1 billion cups of coffee annually yet had received over 700 burn complaints in the previous decade—an incident rate of roughly 1 in 1 million cups, or 0.000007%. Morgan argued that while the raw number seemed low, each incident represented a severe consumer injury. The company’s refusal to adjust temperature or warn customers demonstrated negligence. McDonald’s defense claimed that customers should know hot coffee is hot and that the 700 complaints were statistically insignificant. The jury disagreed. They found McDonald’s liable for selling coffee at an unnecessarily high temperature without adequate warning, leading to Liebeck’s injuries. The jury awarded $200,000 in compensatory damages (reduced to $160,000 because Liebeck was deemed 20% at fault) and $2.7 million in punitive damages—equivalent to two days’ worth of McDonald’s coffee sales. Ultimately, the parties reached a confidential settlement, reportedly around $600,000, with Liebeck agreeing not to disclose details. As part of the fallout, McDonald’s lowered its coffee serving temperature globally.

Frequently Asked Questions

How hot was McDonald’s coffee in the Stella Liebeck case?

McDonald’s coffee was served at 82–86°C (180–187°F), significantly hotter than typical home-brewed coffee (70–75°C) or even Starbucks. This extreme temperature was a key factor in causing Liebeck’s severe burns.

What injuries did Stella Liebeck suffer from the coffee spill?

Liebeck sustained third-degree burns on 6% of her body, including her thighs and groin, and first- or second-degree burns on 16% of her skin. She required eight days of hospitalization, multiple skin graft surgeries, and lost 20 pounds (dropping to 38 kg). Her recovery lasted two years.

Why did the jury award punitive damages in the McDonald’s coffee lawsuit?

The jury awarded $2.7 million in punitive damages (later settled for around $600,000) because McDonald’s knowingly served coffee at an excessively high temperature without proper warnings, despite hundreds of prior burn complaints. The amount symbolized two days’ worth of the company’s coffee sales and was meant to punish and deter reckless corporate behavior.

Did McDonald’s change its coffee temperature after the lawsuit?

Yes. Following the publicized lawsuit and settlement, McDonald’s lowered the serving temperature of its coffee globally. The exact new temperature was not disclosed, but it was reduced from the original 82–86°C to a safer level.

Was the Stella Liebeck case really about a greedy customer?

No. Initial media portrayals dismissed the case as frivolous, but court evidence showed Liebeck suffered life-altering third-degree burns and that McDonald’s had ignored over 700 prior burn complaints. The case became a landmark example of corporate responsibility and product safety.
