Grillmasters and backyard BBQ enthusiasts who have tried grilling with both natural gas and propane often refer to natural gas grilling as more of a ‘dry heat’ compared to propane’s more ‘wet heat.’ They say that propane, being a gas derived from a liquid form, has a ‘wet heat’ quality to it that can change the texture and consistency of food.
Natural gas provides a better char and more smoky flavor compared to propane gas grills. This makes natural gas grills preferable for flame grilling applications.
