Why did Puroast sue Trader Joe's?

Because Trader Joe's Low Acid coffee tested at pH 5.44 (not genuinely low acid) and contained approximately 50% less caffeine than regular coffee with zero label disclosure — deceiving millions of consumers who rely on the low acid label for health reasons.

What is Puroast asking for in the lawsuit?

Two things: mandatory clearer labeling when caffeine is reduced, and an official federal standard defining what qualifies as low acid coffee so consumers can finally trust the label.

What makes Puroast genuinely low acid?

Puroast's patented slow-roasting process converts chlorogenic acids into antioxidant phenolic compounds — producing 5X less acid and 5X more antioxidants with 100% of the caffeine preserved. Verified by UC Davis and NC A&T University.

Where does the lawsuit stand today?

The Puroast v. Trader Joe's case (Case No. 1:25-cv-20696) is in mediation. Two independent consumer class action lawsuits have since been filed by real customers, and Bursor and Fisher P.A. filed McIntosh v. Trader Joe's in April 2026 in the S.D. New York.
