Puroast's Bourbon Cinnamon Twist K-Cups bring the warmth of toasted cinnamon and smooth bourbon notes into a single-serve format — without the bitterness, without the acid, and without ever sacrificing convenience. This is what a flavored K-Cup is supposed to taste like: complex, warm, and genuinely smooth from the first sip to the last.
Most cinnamon-flavored K-Cups follow the same formula: industrial flash-roasted coffee at pH ~5.0, plus artificial cinnamon flavoring sprayed on top. The result is a drink that smells warm and inviting but hits your stomach with a wave of acid — and tastes bitter the moment the cinnamon note fades. The flavor is cosmetic. The acid is real. Puroast Bourbon Cinnamon Twist K-Cups start from a completely different place — a genuinely low acid base built through traditional slow roasting, then naturally flavored with cinnamon and bourbon notes that complement the coffee rather than mask it.
The problem with cinnamon K-Cups from mainstream brands runs deeper than just ingredient quality. Flash roasting — the industrial standard used by Green Mountain, Folgers, and Dunkin' — locks in high concentrations of quinic acid and chlorogenic acid at pH levels between 4.7 and 5.2. These acids are what make conventionally roasted coffee bitter. They're also what makes it harsh on the stomach, the esophagus, and the gut lining. Add artificial cinnamon flavoring on top of that acidic base and you get a drink that briefly smells like the holidays and tastes like regret.
What makes Puroast's K-Cups different isn't the flavoring — it's the roasting. UC Davis researchers Dr. Toshio Shibamoto and Dr. Takayuki Shibamoto published peer-reviewed research confirming that Puroast's traditional slow roasting process produces 5X less acid than conventionally roasted coffee. This isn't a marketing claim — it's a measured, published, replicated scientific finding presented to the American Chemical Society.
The traditional slow roasting method — pioneered using indirect biomass heat in Venezuela and later patented in the United States — converts quinic acids and chlorogenic acids into phenolic antioxidant compounds rather than locking them in as bitter, gut-irritating acids. The result is a coffee that measures pH 5.82 — significantly higher (less acidic) than the pH 5.0 industrial standard. When that low acid base is then naturally flavored with cinnamon and bourbon notes, the flavor has nothing to fight against. There's no bitterness to mask. No acid to override. The flavors land cleanly and linger naturally.
Bourbon Cinnamon Twist opens with a warm, spiced aroma — toasted cinnamon with a hint of vanilla sweetness that greets you the moment you lift the lid of your Keurig. In the cup, the cinnamon note is present but not sharp — it wraps around the coffee's natural richness rather than overpowering it. The bourbon warmth develops in the mid-palate, and the finish is smooth and clean with no acid burn or bitter aftertaste.
Brewed black, Bourbon Cinnamon Twist is exceptional — the kind of flavored coffee that doesn't need cream or sugar to taste complete. With a splash of unsweetened oat milk, the cinnamon and bourbon notes deepen and the drink takes on a genuinely café-quality character. For iced coffee drinkers, brew on the lowest volume setting (4–6 oz) to create a concentrate, then pour over ice — the flavor intensifies beautifully cold.

| Dunkin' Cinnamon Spice | Artificial | High — pH ~5.0 | ❌ |

Yes — and this is the point most flavored K-Cup buyers miss entirely. For people with acid reflux, GERD, IBS, or general stomach sensitivity, the problem with flavored coffee has never been the flavor itself. It's the acid in the base coffee. Cinnamon has natural anti-inflammatory properties, but those properties can't overcome the gut irritation from a pH 5.0 industrial roasted base. The cinnamon is decoration. The acid is the problem.
Puroast Bourbon Cinnamon Twist is built on a genuinely different base — one that measures pH 5.82 and has been verified by UC Davis to produce 5X less acid than conventional coffee. For acid-sensitive drinkers, this is the only cinnamon K-Cup that delivers the warmth and spice of cinnamon coffee without the gut consequences. That's not a small distinction — it's the only distinction that matters for the 60 million Americans who experience acid reflux regularly.
Bourbon Cinnamon Twist K-Cups are for anyone who loves the idea of a warm, spiced coffee drink but has been burned — literally — by the acid in every version they've tried. It's for the person who gave up on cinnamon coffee after too many mornings with heartburn. It's for the GLP-1 user whose medication has made their stomach more sensitive to acidic foods. It's for the coffee drinker who wants genuine flavor complexity in a 90-second K-Cup format without any compromise on quality or gut comfort.
It's also simply for anyone who loves great coffee. The low acid base isn't just a health feature — it's a flavor feature. Without bitterness and harsh acids competing with the flavor profile, cinnamon and bourbon notes can express themselves fully. The result is a flavored K-Cup that tastes more like flavored coffee and less like flavored acid.
Yes. All Puroast coffees — including K-Cup formats — use the same traditional slow roasting process verified by UC Davis to produce 5X less acid than conventional coffee. The K-Cup pod format does not change the low acid profile of the underlying roast.
Puroast uses natural flavoring for all its flavored coffees. The cinnamon and bourbon notes are derived from natural sources with no artificial additives or chemical flavor carriers like propylene glycol.
Cinnamon has natural anti-inflammatory properties, but it can't counteract the acid in a conventionally roasted coffee at pH ~5.0. Starting with a genuinely low acid base like Puroast (pH 5.82) is what makes the difference for acid reflux sufferers. The base is the medicine.
Absolutely. Brew on the 4–6 oz setting for a concentrate, then pour immediately over a full glass of ice. The flavor intensifies beautifully cold — the cinnamon note becomes more prominent and the bourbon warmth becomes a subtle sweetness in the background.
Green Mountain Cinnamon uses artificial flavoring on a high-acid industrial roasted base (pH ~5.0). Puroast Bourbon Cinnamon Twist uses natural flavoring on a low acid base verified at pH 5.82 — 5X less acid. The flavor is more natural, the finish is cleaner, and there's no acid burn.
Verified by UC Davis. Naturally flavored. Zero bitterness. Zero compromise.
