Hazelnut coffee is one of the most popular flavored coffees in America. But most hazelnut coffees are built on a deeply flawed formula — artificial hazelnut flavoring sprayed over cheap, high-acid industrial roasted beans. The hazelnut note fades after a few sips. The acid doesn't. For the 60 million Americans who experience acid reflux and still love coffee, hazelnut coffee has always been a painful trade-off. Puroast's Hazelnut changes that equation entirely.
Walk down the coffee aisle and you'll find dozens of hazelnut options — Green Mountain, Dunkin', Folgers, Starbucks. What they all have in common: a high-acid industrial roasted base at pH ~5.0, artificial hazelnut flavoring derived from chemical compounds rather than actual hazelnuts, and a bitter aftertaste that the hazelnut note can't fully mask. The flavor is cosmetic. The acid is real.
The deeper problem is that artificial hazelnut flavoring is specifically designed to survive in a high-acid environment — which means it's engineered to be pungent and synthetic rather than natural and nuanced. Real hazelnut flavor is subtle, warm, and slightly sweet. What you get in most commercial hazelnut coffees is a chemical approximation that lands sharp and fades fast, leaving nothing behind but the bitterness of the base roast.
Puroast Hazelnut starts with the same traditional slow roasting process used across the entire lineup — the process UC Davis researchers verified produces 5X less acid than conventional coffee. This isn't a minor tweak — it's a fundamentally different approach to roasting. Where industrial flash roasting locks quinic acids and chlorogenic acids into the bean as bitter, gut-irritating compounds, traditional slow roasting converts those acids into phenolic antioxidants. The result is a coffee at pH 5.82 that has significantly less bitterness and dramatically more antioxidant activity.
When natural hazelnut flavoring is layered on top of that clean, smooth base, the flavor has nothing to fight against. There's no bitterness competing with the hazelnut note. No harsh acid cutting through the finish. The result is a hazelnut coffee that doesn't need to mask anything — because there's nothing to mask. The hazelnut note opens warm and toasted, lingers in the mid-palate, and finishes cleanly without any chemical aftertaste.
For people with acid reflux, GERD, or sensitive stomachs, hazelnut coffee has always been off the menu — not because of the hazelnut, but because of the coffee underneath it. Conventional hazelnut coffees at pH ~5.0 deliver the same acid load as any other industrial roasted coffee. The flavoring doesn't change the pH. The scent doesn't change the pH. Only the roasting method changes the pH.
Puroast Hazelnut is one of the very few flavored coffees that acid-sensitive drinkers can enjoy without consequence. The 5X lower acid profile verified by UC Davis is built into the roasting — not added afterward, not neutralized by an additive, not offset by marketing language about "smooth" or "gentle" roasting that has no scientific basis. The pH is measurable. The difference is real.
| Brand | Flavoring | Acid Level | Gut Friendly |
|---|---|---|---|
| Green Mountain Hazelnut | Artificial | High — pH ~5.0 | ❌ |
| Dunkin' Hazelnut | Artificial Syrup | High — pH ~5.0 | ❌ |
| Folgers Hazelnut | Artificial | High — pH ~5.0 | ❌ |
| Puroast Hazelnut | Natural | 5X Less — pH 5.82 | ✅ |
Yes. Like all Puroast coffees, Hazelnut is slow roasted using a traditional method verified by UC Davis to produce 5X less acid than conventional coffee — measuring pH 5.82 vs. pH ~5.0 for industrial roasted coffees.
Most hazelnut coffees are bad for acid reflux because they're built on high-acid industrial roasted beans at pH ~5.0. Puroast Hazelnut is the exception — 5X less acid, naturally flavored, and verified by UC Davis. The hazelnut flavoring doesn't affect the pH — the roasting method does.
No. Puroast uses only natural hazelnut flavoring with no artificial additives or chemical flavor carriers like propylene glycol.
Yes — and it's excellent cold brewed. Use a coarse grind at 1:8 ratio in cold filtered water. Steep 16–18 hours in the refrigerator. The hazelnut note becomes more prominent and the low acid base makes for an exceptionally smooth cold brew that doesn't need sweetener.
Dunkin' hazelnut uses artificial syrup flavoring on a high-acid industrial roasted base (pH ~5.0). Puroast uses natural hazelnut flavoring on a low acid base at pH 5.82 — 5X less acid, no artificial additives, and a finish that doesn't need sugar to taste complete.
Natural flavoring. 5X less acid. pH 5.82. UC Davis verified.
