The RB003 chilli is a modern superhot Capsicum chinense variety that has gained attention in the chilli-growing community for its extreme heat, unusual genetics, and dramatic appearance.<\/p>\n
<\/p>\n
It is widely believed to have been bred by Australian grower Ross Barber, with most sources describing it as a cross between a Carolina Reaper (often yellow forms) and a 7 Pot Brainstrain type pepper.<\/p>\n
<\/p>\n
Appearance<\/p>\n
RB003 pods are very distinctive:<\/p>\n
Twisted, heavily wrinkled \u201cscorpion-like\u201d shape<\/p>\n
Often with a pronounced pointed tail (\u201cstinger\u201d)<\/p>\n
Thick, bumpy skin with a rough, brain-like texture<\/p>\n
Ripens from green\u00a0 to mustard\/yellow or intermediate tones\u00a0 to deep red (sometimes other unstable colour variants appear)<\/p>\n
<\/p>\n
Heat level<\/p>\n
Estimated around 1,000,000 to 2,000,000+ Scoville Heat Units (SHU)<\/p>\n
Typically described as Carolina Reaper-class heat or higher<\/p>\n
No widely accepted lab-tested SHU value exists, so figures are based on grower reports and comparisons<\/p>\n
<\/p>\n
In practical terms, it delivers:<\/p>\n
Very fast onset burn<\/p>\n
Strong full-mouth and throat heat<\/p>\n
Long-lasting intensity, often lingering well after consumption<\/p>\n
<\/p>\n
Flavour profile<\/p>\n
Despite the extreme heat, RB003 is often noted for:<\/p>\n
Fruity and citrus-like top notes<\/p>\n
Light floral undertones<\/p>\n
Mild earthiness (varies by grower and ripeness)<\/p>\n
This makes it more interesting than many \u201cpure heat\u201d superhots, especially for hot sauces.<\/p>\n
<\/p>\n
Plant characteristics<\/p>\n
Vigorous Capsicum chinense growth habit<\/p>\n
Medium-to-tall plants (often over 1 m in good conditions)<\/p>\n
Productive but sometimes variable (not fully stabilised)<\/p>\n
Prefers warm, sunny conditions and long growing seasons<\/p>\n
<\/p>\n
Why growers like it<\/p>\n
Extremely high heat level for chilli challenges and superhot collectors<\/p>\n
Visually striking pods<\/p>\n
Some phenotypes show unusual colour or shape variation (genetic instability adds interest)<\/p>\n
Useful in ultra-hot sauces, powders, and ferments<\/p>\n
<\/p>\n
In short: RB003 is a newer-generation superhot hybrid prized for Reaper-level heat, aggressive scorpion-like pods, and a surprisingly fruity flavour profile underneath the burn.<\/p>\n","protected":false},"excerpt":{"rendered":"
