Questions

Frequently Asked Questions

What makes peppers hot?
Peppers get their heat from a chemical compound called capsaicin, which is found primarily in the white pith (placenta) of the pepper, not the seeds. Read our capsaicin guide for the full science.
How do I stop pepper burn on my hands or mouth?
Capsaicin is oil-soluble, not water-soluble. Drinking water spreads it. Use dairy (milk, yogurt) which contains casein to break the bond, or alcohol/acidic foods. See our stop pepper burn guide for detailed remedies.
When should I start pepper seeds indoors?
Start pepper seeds 8–12 weeks before your area's last expected frost date. Superhot varieties (like Reapers) need the full 12 weeks as they grow slower. Use our planting calculator for exact dates.
What is the hottest pepper in the world?
Currently, Pepper X holds the Guinness World Record, averaging 2.69 million Scoville Heat Units (SHU), surpassing the Carolina Reaper. See our hottest peppers guide for the full ranking.
