Butch Taylor named this pepper the CPR — Chocolate Primo Reaper — because he genuinely could not decide which of the two was the father.
He found it as an accidental cross in his own growing operation. A dark chocolate pod that didn't look exactly like a Reaper, didn't look exactly like a 7 Pot Primo, but shared enough with both that determining the pollen parent was impossible without genetic testing he was not going to do. So he gave it a name that covered all the bases and moved on. The pepper earned its own reputation from there.
This is the same Butch Taylor who developed the Trinidad Scorpion Butch T — the pepper that held the Guinness World Record from 2011 to 2013. He knows what a significant cross looks like. The CPR is a different kind of achievement: not a record-holder, not a heat weapon engineered for maximum SHU, but a dark, visually distinctive superhot with a genuinely unusual origin story and flavor reviews that are among the most polarized in the chilihead community. Some growers love it. One experienced reviewer called it the worst-tasting pod he had ever eaten. That kind of honest disagreement is worth documenting properly.
This is the full profile. Origin first, then the heat, then the flavor — with the real reviews, not the curated ones.
Who Made It and Why the Name Is an Honest Admission
The CPR was created — or more accurately, discovered — by Butch Taylor, a Mississippi-based grower and hot sauce maker with a documented history of producing significant superhot crosses. His prior work includes the Trinidad Scorpion Butch T, which he developed through years of selecting within Trinidad Scorpion stock and which held the Guinness World Record at 1,463,700 SHU from 2011 to 2013. That is relevant context: Taylor's output includes both deliberate, decade-long breeding projects and an accidental discovery he named after his own uncertainty.
The CPR was the latter.
Somewhere in Taylor's growing operation, a pod appeared that was clearly a cross — dark chocolate in color, structurally resembling both the Carolina Reaper and the 7 Pot Primo — but he could not confirm which of the two was the pollen parent. The mother plant is not publicly documented either. What he knew was that the pod was intensely hot, visually striking, and chocolate in phenotype.
He named it the Chocolate Primo Reaper — CPR — because both Primo and Reaper were possible, and the name honored the ambiguity honestly. That kind of straightforwardness about what you do and don't know is actually rare in superhot breeding, where origin stories are often tidy and certain in retrospect. Taylor's version is more useful: this is what it looks like, this is where it came from as best I can determine, and here is the name that captures that uncertainty in three letters.
He subsequently worked to stabilize the chocolate phenotype, and the CPR has been circulating in the collector and commercial seed community since. It shares the accidental-discovery origin with peppers like the Jay's Peach Ghost Scorpion — where the cross happened without intention in a growing environment where multiple varieties had access to shared pollinators — and that shared origin type is worth noting. Some of the most interesting superhots in circulation came from a grower paying close attention to something they did not plan.
The Parents: What Each Side Contributes
The CPR's parentage is unconfirmed, but the two candidate parents are among the most documented superhots in the world. Understanding what each one would contribute explains why the CPR behaves the way it does regardless of which specific cross produced it.
Carolina Reaper
Ed Currie's Pakistani Naga × La Soufrière habanero cross — certified at 1,641,183 SHU average by Guinness, with individual pods measured at 2,200,000 SHU under optimized conditions. The Reaper would contribute to the CPR:
Pod structure — the gnarled, blistered, ribbed pod shape that the CPR clearly carries
Chocolate phenotype potential — the Reaper exists in multiple color variants including dark chocolate; Currie himself has noted eleven color phenotypes in his Reaper lines
High oil content and placental density — the Reaper's primary heat mechanism; dense capsaicin-bearing tissue throughout the pod
Fruity initial flavor — the brief tropical sweetness before the burn; if the CPR's initial flavor notes trace to the Reaper side, this is the source
7 Pot Primo
Troy Primeaux's Louisiana-bred stinger-tailed superhot with documented average SHU well above one million. The Primo would contribute:
Elongated pod shape and texture — the Primo's deeply ridged, heavily wrinkled pod structure; clearly visible in the CPR's pod morphology
Stinger tendency — the Primo's characteristic tail point, which appears on some CPR pods
Capsaicin ceiling — the 7 Pot family is among the highest-oil-content superhot lineages; Primo genetics would push heat expression upward
Burn concentration in the mouth — the Primo's burn tends to concentrate in the front palate and mouth rather than the sinuses; this matches the CPR's documented burn profile
The honest read: the CPR looks like both parents simultaneously. The dark chocolate phenotype is common to both when the right recessive genes express. The pod structure could be either. The burn profile matches the Primo more than the Reaper. Whether that reflects actual Primo parentage or simply which parent's traits dominated in expression is impossible to say without genetic sequencing.
Heat: What the Numbers Say and What Tasters Report
The documented heat range for the CPR is 1,000,000 to 1,500,000 SHU from the primary seed and retail sources. Bohica Pepper Hut, one of the more reputable superhot seed operations in circulation, lists it firmly in the 1M–1.5M range. Texas Hot Peppers estimates it near 2,000,000 SHU — a higher figure without sourced lab data to back it.
No independent HPLC-certified average exists for the variety. All figures are estimates based on growing experience and subjective heat assessment.
What growers and tasters report consistently about the burn profile:
Onset: Moderate — not the fast, immediate sting of a Scorpion or Fatalii; more like the Primo's patient build
Location: Concentrated in the mouth, tongue, and roof of the mouth — notably more front-palate than the Reaper, which spreads broadly to throat, sinuses, and ears
Peak intensity: Serious. Multiple sources describe it as a true superhot; the mouth concentration makes it feel different from Reaper-level heat even if the SHU figures are comparable on paper
Duration: Extended; the chocolate phenotype in Capsicum chinense varieties often carries higher dihydrocapsaicin ratios which extend burn duration — the mechanism behind this is covered in our capsaicin biology post
PepperInfo's reviewer — an experienced taster with a documented record across dozens of varieties — noted that despite its heat, the CPR does not feel as extreme as a Carolina Reaper or 7 Pot Primo in overall intensity. He rated heat at a 6 out of 10 on his personal scale, having initially placed it at 7 before revising downward. That is one data point, not a consensus, but it is a credible data point from a reviewer who does not hedge.
Flavor: The Most Honest Review in the Community
This is where the CPR's profile gets interesting, and where intellectual honesty matters most.
Seed vendors universally describe the CPR as floral and fruity with a sweet initial note. That characterization is accurate for the first moments of contact — multiple independent sources confirm the floral-and-slightly-sweet opening before the burn engages. That much is settled.
What happens next is where the reviews diverge.
The positive case: Texas Hot Peppers describes a pleasant sweetness that persists until the heat takes over. Bohica Pepper Hut characterizes it as genuinely fruity and floral — a flavor-forward superhot that delivers complexity alongside the burn. These are consistent with the Reaper side of the parentage, where the habanero genetics contribute a brief but real tropical flavor window.
The critical case: PepperInfo's reviewer — after completing the full eat — described it as "one of the worst tasting pods I've ever eaten." In his words: "It started out floral and slightly sweet, then turned bitter. It tasted like I was eating ear wax. I absolutely hated it." He rated flavor at 2 out of 10. This is a brutal assessment, but it comes from a reviewer who is equally direct when he likes something, which gives the negative review credibility rather than diminishing it.
The honest synthesis: the CPR's flavor appears to follow a specific arc — floral and sweet at first contact, then a bitter mid-palate turn that divides tasters sharply. Growers who eat their way through multiple pods in a season often report that the bitter note becomes more pronounced over the course of the eat, which would explain why quick-assessment reviews tend to be more positive than those from experienced reviewers who complete the full experience.
For culinary use, the CPR is most appropriate in applications where the initial floral-sweet note can be captured before the mid-palate bitterness emerges:
Fermented sauces where acidity can balance bitterness — a vinegar-forward ferment suppresses bitter notes effectively
Powder blending — dried CPR loses some of the bitter volatile compounds; the powder tends to be more forgiving than the fresh pod
Extreme heat applications — where heat delivery is the primary goal and flavor nuance is secondary
Pod Characteristics
At full maturity, the CPR pod:
Color: Deep chocolate-brown — the defining visual characteristic; a dark, matte brown at full ripeness that is more saturated than most chocolate-phenotype varieties
Surface: Heavily wrinkled and ribbed, gnarled in the Reaper-Primo tradition; the surface texture is one of the most visually dramatic in the chocolate superhot category
Structure: Reflects the ambiguity of its origin — looks like a Reaper from one angle, like a Primo from another; some pods show a slight stinger tendency, others taper more cleanly
Size: Consistent with other Reaper-family varieties — compact but substantial
Wall thickness: Moderate; the placental membrane is dense, which is the primary capsaicin-bearing tissue and the source of both the heat and the bitter mid-palate note some tasters encounter
Oil content: High, visible on the cut surface at full ripeness — a reliable indicator of capsaicin density and flavor compound concentration
The CPR's appearance is universally noted as a strength by reviewers who are otherwise critical of the flavor. PepperInfo's reviewer — who gave it a 2 out of 10 on flavor — specifically noted that "the pods are very cool looking" as the one positive in an otherwise brutal assessment. The visual impact is genuine and undisputed.
Growing Characteristics: Plan for Patience
Every grower source that covers the CPR in any detail agrees on one thing: this is a slow, low-yield plant that requires a very extended season. There is no dissenting view on this point across the sources we consulted.
What that means in practice:
Germination: Standard superhot germination protocol — bottom heat at 80–85°F, 14–21 days minimum. No unusual germination issues are reported.
Growth rate: Slow. The CPR is notably slower to reach transplant size and slower to mature than most other superhots in the same heat class.
Season length: Extended — growers consistently note that the CPR needs more time than a standard Carolina Reaper season. In our East Tennessee environment, this means an early January seed start is essential, and the high-tunnel environment extending our effective season is not optional for this variety — it is required.
Yield: Low. The CPR does not set pods heavily even under good conditions. It is a collector and specialty variety, not a commercial production pepper. Do not plant it expecting Tiberius Mauler-level pod counts.
Plant height: Reaches up to 4 feet under good conditions — normal for the Reaper-Primo size class.
Staking: Recommended despite the low yield, because what pods do set are heavy relative to the branch structure.
Our four-phase fertigation protocol — Venturi staged nutrient delivery through the mound, calibrated to the plant's development phase — is specifically designed for varieties like the CPR where the plant needs consistent, precisely timed nutrient availability to compensate for a slow growth trajectory. You cannot rush the CPR with more fertilizer. You can, however, keep it from stalling by ensuring the nutritional environment is correct at every phase.
For a variety this demanding in growing time and this low in yield, the decision to grow it is a statement about what you value in a lineup. We value documentation, variety depth, and the collector community. The CPR earns its space on those terms.
Comparison Table
Variety | SHU Range | Flavor Profile | Burn Location | Yield | Season Length | Origin Type |
CPR (Chocolate Primo Reaper) | 1M–1.5M est. | Floral-sweet opening, bitter mid-palate (polarizing) | Mouth, tongue, roof of mouth | Low | Extended | Accidental cross, Butch Taylor |
Carolina Reaper | 1.64M avg (cert.) | Tropical fruit, cherry, cinnamon | Broad: mouth, throat, sinuses | Moderate-High | Standard | Deliberate cross, Ed Currie |
7 Pot Primo | ~1.47M avg | Fruity-citrus, floral | Front palate, sustained | Moderate | Standard | Deliberate development, Troy Primeaux |
Primotalii | 1.6M–2.2M est. | Citrus, clean floral | Immediate sting + sustained climb | Variable | Extended | Disputed origin, Chris Saunders |
Chocolate Ghost Pepper | 855K–1M | Smoky, earthy, mild sweetness | Slow-build, throat-heavy | Moderate | Standard | Natural phenotype variant |
Trinidad Scorpion Butch T | 1,463,700 SHU peak (cert.) | Citrus-tropical | Gradual build, full-mouth | Heavy | Standard | Deliberate breeding, Butch Taylor |
Fried Chicken Pepper | 850K–1M+ | Citrus, floral, earthy sweet | Gradual build, mouth-coating | Heavy | Standard | Deliberate cross, Rocco Maltesi |
Notes on the table:
CPR is the only variety in the lineup with a documented flavor controversy — the sweet/bitter split across experienced reviewers is a genuine characteristic, not reviewer error
CPR and Primotalii share accidental-discovery origins; both were found rather than engineered
Butch Taylor created both the CPR and the Butch T, making him one of the few breeders in the superhot community with a documented record-holder AND a polarizing dark-horse variety
Low yield is the CPR's primary commercial limitation; it is grown for documentation and variety depth, not production volume
Harmony Springs Farmer's Note
By Gene Chumley | Head Grower, Harmony Springs Farm
The CPR is in our lineup for the reason we document any difficult variety: because the chilihead community deserves honest firsthand data, and because you cannot get that data without growing the plant yourself.
The slow growth is real. We started CPR seeds in January alongside everything else in the lineup, and the development rate is noticeably slower than the Reaper, the Primo, and every Scorpion variety in the same trays. The plant is not fragile — it is simply deliberate. It does not respond to impatience.
What I am watching this season: pod-set timing relative to the other Reaper-family varieties in the high tunnel, placental tissue density on the cut surface at first harvest, and my own honest flavor assessment with specific attention to the sweet-to-bitter arc that PepperInfo's reviewer documented. That kind of taster disagreement is real and worth investigating firsthand.
If the bitter mid-palate is as pronounced as that review suggests, we will document it. If it is milder than reported — which some grower accounts imply — we will document that too. That is what "Precision Grown. Engineer Verified." means in practice: we do not publish flavor notes we have not confirmed ourselves.
Mid May Status: Most documentation online describes this as a slow producer with low yields. We are noting very strong plants with several flowers showing in mid May. These are actually moving along faster than many other superhots in our tunnels.
Pod availability will be limited given the yield profile. Join the list.

Frequently Asked Questions: CPR Pepper (Chocolate Primo Reaper)
What is the CPR pepper? The CPR pepper — short for Chocolate Primo Reaper — is a Capsicum chinense superhot discovered by Butch Taylor, the same Mississippi grower and breeder behind the Trinidad Scorpion Butch T. It is an accidental cross that resembles both the Carolina Reaper and the 7 Pot Primo in pod structure, ripens to a deep chocolate-brown color, and delivers estimated heat of 1,000,000 to 1,500,000 SHU with some vendor estimates reaching near 2 million SHU.
What does CPR stand for in the pepper world? CPR stands for Chocolate Primo Reaper. The name reflects the uncertainty in the pepper's origin — Butch Taylor discovered it as an accidental cross and was not certain whether the Primo or the Reaper was the pollen parent, so both are represented in the acronym alongside the chocolate phenotype color.
Who created the CPR pepper? The CPR pepper was discovered by Butch Taylor of Mississippi, who is also the grower behind the Trinidad Scorpion Butch T. Taylor found the CPR as an accidental cross in his growing operation. He was uncertain whether the cross involved a 7 Pot Primo or a Carolina Reaper as one of the parents, which is why the name includes both. He subsequently worked to stabilize the chocolate phenotype.
How hot is the CPR pepper? The CPR pepper is estimated at 1,000,000 to 1,500,000 SHU by most sources. Texas Hot Peppers estimates it near 2,000,000 SHU. No independent HPLC-certified average exists. The burn concentrates in the mouth, tongue, and roof of the mouth rather than spreading broadly to the sinuses. Community reviewers note it is perceived as less extreme than a Carolina Reaper or 7 Pot Primo despite the high estimated SHU.
What does the CPR pepper taste like? Flavor reviews are genuinely split. Most vendors describe a floral and fruity initial flavor with a sweet note before the burn. PepperInfo's experienced reviewer describes it starting floral and slightly sweet before turning bitter — a strongly negative assessment. The honest answer is that the CPR's flavor is polarizing. Growers who enjoy dark chocolate-phenotype peppers often appreciate it; those expecting Reaper-level flavor complexity may be disappointed.
Is the CPR pepper a good producer? No. The CPR is widely noted as a slow grower with a low yield. It requires a very extended growing season and does not produce heavily even under good conditions. It is a collector and specialty variety rather than a commercial production pepper.
What does the CPR pepper look like? The CPR produces deeply wrinkled, chocolate-brown pods that resemble both the Carolina Reaper and the 7 Pot Primo in structure. Pods are gnarled and heavily ribbed with the visual intensity typical of the Reaper family. The dark chocolate color is the variety's most distinctive visual feature, and it is one of the few CPR characteristics that receives consistent praise across even its most critical reviewers.
Can I buy CPR seeds from Harmony Springs Farm? Yes. Harmony Springs Farm grows the CPR (Chocolate Primo Reaper) in its high-tunnel operation in Blountville, Tennessee. Given the variety's documented slow growth and low yield, our controlled fertigation protocol and soil preparation provide the stable environment this pepper needs to perform.
