The Short Version
Trader Joe’s faces legal action over its “low acid” coffee’s misleading caffeine claims, with lab tests showing it contains just 45–51% of the caffeine in regular coffee, conflicting with its marketing as a full-caffeine brew.
Here’s a federal class action alleging that Trader Joe’s misled consumers about the caffeine content in its “French Roast Low Acid” coffee. The lawsuit, filed last week in California’s federal court, claims the product’s caffeine levels—around half that of regular coffee—conflict with its marketing as a full-flavored, energizing brew. The complaint argues the company failed to disclose that the coffee’s caffeine content significantly undercuts typical expectations for a “full-caffeine” experience.
“The amount of caffeine in a coffee blend affects a consumer’s purchasing decision.”
The Label’s Double-Edged Sword
Trader Joe’s label touts a “dark, rich brew with full, strong flavors” but omits the caffeine punch. The back label describes a “long, slow roast” and a “chemical-free, natural steaming process” to reduce acidity. Yet lab tests from a 2025 lawsuit by Puroast Coffee Company show the product contains just 45–51% of the caffeine in its regular counterparts. The complaint argues this undermines the “low acid” claim, which is based on acidity thresholds, not caffeine levels.
A Legal Crossroads for Coffee Claims
The new class action explicitly references the Puroast case, which raised similar concerns about caffeine levels and low-acid standards. Both lawsuits highlight a growing tension: how to balance transparency with marketing. The complaint asserts that for many consumers, caffeine is a key factor in purchasing decisions. “The amount of caffeine in a coffee blend affects a consumer’s purchasing decision,” it states.
“The amount of caffeine in a coffee blend affects a consumer’s purchasing decision.”
This isn’t just about labels. It’s about trust. When a product’s promise—whether low acid, smooth, or energizing—doesn’t match its reality, the line between marketing and misinformation blurs. What happens when the science behind a claim isn’t just murky, but actively misleading? What’s the cost of a coffee that promises energy but delivers a half-caff punch?
Regulatory bodies like the FTC are increasingly scrutinizing caffeine labeling in the coffee industry, with guidelines emphasizing clarity and accuracy. As these cases unfold, they underscore the need for brands to align their claims with the science—and the expectations—of their customers.
