Low Acid Coffee Myths — Debunked with Peer-Reviewed Science
The definitive low acid coffee myth-busting guide — bean selection, dark roast, cold brew, decaf, organic — every myth refuted with peer-reviewed science.
Chapter 8: The Wild West of Low Acid Coffee — How an Unregulated Label Became the Industry's Most Abused Claim
Six Out of Seven “Low Acid” Coffees Tested Were High Acid. Here’s the Truth.
In Chapter 7, Dr. Shibamoto's peer-reviewed research confirmed what thousands of early Puroast customers had already experienced: this coffee was genuinely, measurably, scientifically different. 5X less acidic. 5X more antioxidants. Proven by UC Davis. Presented to the American Chemical Society.
That proof created a new problem. Once it became clear that low acid coffee was real — that consumers wanted it, that the health benefits were documented, and that the market was growing — the industry responded the way it always does when a new category emerges: with imitation, exaggeration, and fraud.
The Wild West of low acid coffee had begun.

The NC A&T Study: 6 of 7 Low Acid Coffees Were High Acid
In 2024, NC A&T State University published a landmark study that confirmed what Puroast had suspected for years. Researchers tested seven coffees that were marketed and sold as “low acid coffee.” Six of the seven were actually high acid — no different from standard commercial coffee.
Six out of seven. Only one was genuinely low acid.
⚠ Buyer Beware
NC A&T State University (2024) found that 6 of 7 coffees marketed as “low acid” were actually high acid. These are marketing companies placing a label on standard coffee to profit from the growing low acid category — while lying to consumers who are choosing coffee based on health needs.

Why This Happens — and Why It’s So Dangerous
The “low acid” label is currently unregulated. There is no FDA standard, no independent certification body, and no legal requirement for a company to prove that its coffee is actually low acid before printing those words on a bag. Any brand can claim it. Most do not have the science to back it up.
This is not a minor marketing exaggeration. The people shopping for low acid coffee are often doing so because of genuine health needs — acid reflux, GERD, stomach sensitivity, ulcers. They are making dietary choices based on a label. When that label is false, the consumer is being deceived at exactly the moment they are most vulnerable.
How to Spot a Fake Low Acid Coffee
Before you buy any coffee marketed as low acid, ask these questions:
- Is there independent laboratory testing? Not a claim — actual published results from a credible third-party lab or university.
- Is the reduction in acidity due to roasting, or additives? Some brands use chemical treatments to reduce acid. That is not the same as genuinely low acid coffee produced through roasting.
- Is there peer-reviewed science? Published papers in scientific journals are the gold standard. Marketing copy is not.
- Is it LACCSA certified? LACCSA (Low Acid Coffee Certification Standard Association) is the industry certification Puroast founded to establish a true standard for the category.
- Who verified it? UC Davis. The American Chemical Society. NC A&T. These are names that carry scientific weight. A brand's own marketing team does not.
Don’t Be Fooled by the Label
Choose the Coffee With the Science
Puroast is UC Davis verified, LACCSA certified, and backed by peer-reviewed research. 5X less acidic. 5X more antioxidants. No exceptions.
The Solution: A Standard for the Category
Puroast's response to the Wild West of low acid coffee is not just to outcompete the fakes — it is to build the framework that makes fraud impossible. LACCSA — the Low Acid Coffee Certification Standard Association — is Puroast's initiative to establish a real, independently verifiable standard for low acid coffee claims.
The goal is simple: if a coffee says it is low acid, it should have to prove it. With independent testing. With published results. With a certification that consumers can trust. The same way organic certification works. The same way fair trade certification works.
The category needs a standard. Puroast is building it. And the patent that protects the roasting process behind the only genuinely low acid coffee is the subject of Chapter 9.
