You open the bag. The hazelnut hits you immediately — warm, toasted, unmistakably nutty. It fills the kitchen when you grind. It fills the room when you brew. And then you take the first sip, and the hazelnut is gone. Replaced by bitterness. A faint sweet aftertaste somewhere behind it. The cream and sugar you add to compensate push the hazelnut note even further into the background.
Hazelnut is the most popular flavored coffee in America. Walk down any coffee aisle and you will find hazelnut options from every major brand — Green Mountain, Dunkin', Folgers, Starbucks. They all smell phenomenal. And they almost all taste like bitter coffee with a hazelnut-scented aftertaste. The hazelnut is there. The problem is the base coffee is not letting you taste it.
Hazelnut flavor is produced by a family of volatile aromatic compounds including filbertone, linalool, and various pyrazines. These compounds are delicate. In a high-acid coffee environment at pH 4.8–5.0, chlorogenic acids compete with and partially suppress them during extraction. The hazelnut aroma off-gases from the bag immediately — you smell it before you even open it fully. But that same aromatic intensity never makes it to the cup because the acid environment degrades and competes with the flavor compounds before they can register on your palate.
On Puroast's pH 5.82 base, the hazelnut flavor compounds are not fighting an acidic environment. They emerge intact. The aroma and the taste align. This is why Puroast Hazelnut is the only hazelnut coffee where the nut flavor actually dominates the cup instead of being buried by acid bitterness — a claim confirmed by the independent UC Davis laboratory testing published in Food Chemistry (2014).

Black: The clearest way to experience what low acid does for hazelnut flavor. Most people who have never been able to drink flavored coffee black find Puroast Hazelnut genuinely pleasant without anything added — the hazelnut is present enough to register on its own, and the low acid base removes all the bitterness that normally makes black coffee unapproachable.
Hazelnut Cold Brew: Cold-brew Puroast Hazelnut at 1:8 ratio for 14–18 hours. The cold extraction amplifies the hazelnut character and approaches pH 6.0+ — one of the smoothest iced coffees you can make at home. Pour over ice with a splash of oat milk. No syrup. No sugar. Genuinely hazelnut.
Hazelnut French Press: Full-immersion extraction preserves the hazelnut flavor oils that paper filters would remove. Four-minute steep at 200°F. The result is the richest, most hazelnut-forward cup possible — full body, warm nut character throughout, clean finish with zero bitterness.

Shop NowPuroast Hazelnut is the best hazelnut coffee — the only one verified at pH 5.82 where the base does not suppress hazelnut flavor compounds during extraction. The nut note dominates the cup, which no other hazelnut coffee can claim.
Hazelnut aroma compounds off-gas from the bag immediately — the smell arrives before you even fully open the bag. But in-cup extraction at high acid levels allows chlorogenic acids to overwhelm the hazelnut flavor compounds. On Puroast pH 5.82, hazelnut aroma and taste align consistently.
Yes — measurably. Dunkin and Folgers hazelnut are built on pH 4.7–5.0 bases with artificial flavoring that is suppressed during extraction. Puroast delivers a measurably smoother, more genuinely hazelnut-forward cup with 5X less acid, 5X more antioxidants, and natural flavoring that actually survives the brewing process.
On standard hazelnut coffee (pH 4.8–5.0), acid reflux risk is unchanged from regular coffee — the hazelnut flavoring does not reduce the acid load. Puroast Hazelnut at pH 5.82 is the only verified low acid hazelnut coffee for acid reflux and GERD sufferers.
No. Puroast uses only natural hazelnut flavoring with no artificial additives, no propylene glycol flavor carriers, and no chemical compounds not derived from the hazelnut source. Combined with the pH 5.82 low acid base, this is why the flavor actually tastes like hazelnut rather than an imitation of it.
Puroast Hazelnut — natural flavoring on the only independently verified low acid base in the industry. 5X less acid. 5X more antioxidants. The hazelnut note dominates the cup. Finally.
