This is an awesome set that I have been trying out for the last few weeks. I heartily approve. There are four grinders in this set with peppers ranging from pretty hot to seriously hot. This is great for that one person that needs some extra heat in thier food without everybody else burning up. All these peppers were grown, harvested, and dried by the powerful pepper company and include MOA Scotch Bonnet, Hybrid Scorpion X Douglah, Ghost, and a Dragon's Breath / Carolina Reaper Blend. These are not available for individual purchase.
