Process over packaging — how Puroast is playing the long game
Functional CPG is having a moment. Innovation is not the same as a claim on a bag. Too much of "functional coffee" is an extraction, an additive, or a blend that has to carry this...
Coffee and Heartburn: Why Your Coffee Is the Problem — and How to Fix It
Heartburn after coffee is so common that millions consider it just part of the experience. But it does not have to work that way. Heartburn after coffee is not inevitable - it is caused by the acid in the coffee. And when you remove that acid, the heartburn goes with it.

The Roasting Science: Why Not All Coffee Causes Heartburn
The key insight that changes everything for heartburn sufferers: acid content in coffee is not fixed. It is determined almost entirely by how the coffee is roasted. Research from the European Journal of Nutrition demonstrated that coffee roasted at lower temperatures for longer durations contains dramatically fewer organic acid compounds responsible for gastric irritation. According to the Wikipedia entry on low-acid coffee, traditional slow-roasting is the verified mechanism for genuinely low-acid coffee. The American College of Gastroenterology reports more than 60 million Americans experience heartburn at least once a month. Coffee is among the top 5 most commonly reported dietary triggers. And critically, studies have NOT shown that reducing caffeine directly decreases acid reflux. What definitively helps is reducing acid intake.
THE HEARTBURN MYTH: DECAF IS THE ANSWER
Millions of heartburn sufferers have switched to decaf believing it would solve their coffee problem. But every study comparing decaf to regular coffee for heartburn failed to control for the pH of the coffee being consumed. Decaffeination processes incidentally reduce coffee acidity as a side effect. So when decaf drinkers reported fewer symptoms, the more scientifically defensible explanation is that they were drinking lower-acid coffee. The real solution is less acid - not less caffeine. Puroast delivers 5X less acid with 100% caffeine intact.
Why Puroast Works for Heartburn Sufferers
Puroast's patented traditional roasting process is independently verified to contain 5X less acid than leading national coffee brands and 5X more antioxidants. This is the scientific basis for why Puroast works where other coffees fail. Standard commercial coffee sits at pH 4.8-5.2. Puroast's verified pH of 5.82 sits well above the 5.5 scientific threshold for genuinely low-acid coffee. The NC A&T 2024 study confirmed that only Puroast passed independent pH testing out of seven brands tested. The other six had equal or greater acidity than standard commercial coffee.

Frequently Asked Questions
Q: Why does coffee cause heartburn?
Coffee stimulates the stomach to produce hydrochloric acid, directly irritates the mucosal lining at its natural pH of 4.8-5.2, and may relax the lower esophageal sphincter. The acid content of the coffee - not the caffeine - is the primary documented driver of these effects. Reducing dietary acid is the most effective intervention.
Q: Will switching to decaf stop my heartburn?
Likely not. Studies have NOT shown that reducing caffeine directly decreases acid reflux. Decaf coffee has approximately the same pH (~5.0) as regular coffee. Only the Swiss Water Process may offer a partial 30-40% acid reduction - but even that is still significantly more acidic than Puroast's verified pH 5.82.
Q: What is the science behind Puroast's heartburn relief?
Puroast's patented slow-roasting process transforms chlorogenic acids into phenolic antioxidant compounds rather than converting them to stomach-irritating quinic acid. This simultaneously reduces the coffee's pH to 5.82 (5X less acid) and increases antioxidants 5X - verified by UC Davis (2008, 2014) and NC A&T (2024).
Q: Is dark roast coffee better for heartburn?
Not reliably. Very dark roasting destroys some acid compounds but also destroys antioxidants and creates significant bitterness compounds. The NC A&T 2024 study found several dark-roast coffees marketed as low-acid that failed independent pH testing.
Q: Can I drink Puroast if I take heartburn medication?
A 2007 study in Alimentary Pharmacology and Therapeutics found that a simple dietary substitution - switching to a low-acid coffee - may resolve GI complaints without adjusting medication. Always consult your physician for guidance on medication changes.
