How to choose the right multi-fuel grill

1. Check the fuel flexibility

   Multi-fuel capability allows you to switch between gas and solid fuels. The Ooni Karu 12 supports gas, propane, and other solid fuels, giving you versatility for different cooking styles. The SPIRE and BODEGA models are primarily gas-driven but fall under the multi-fuel category for broader selection. Verify the specific fuel types listed in the attributes to ensure compatibility with your preferred heat source. This flexibility determines how you prepare meals and the variety of flavors you can achieve.

2. Match form factor to space

   Your installation needs dictate the form factor. Built-in units like the SPIRE 36-Inch and BODEGA 30-Inch require permanent outdoor kitchen islands. They measure 40 inches and 26.5 inches wide respectively, demanding precise cabinetry planning. Portable options like the Ooni Karu 12 offer mobility but require floor space. The Nexgrill 4-Burner is a standalone unit at 52.6 inches long. Choose based on whether you need a fixed, integrated look or a movable setup for different locations.

3. Assess cooking capacity needs

   Width and depth determine how much food you can cook at once. The SPIRE 36-Inch grill offers a 40-inch width and 25.2-inch depth, ideal for large gatherings. The BODEGA 30-Inch model provides a 42.3-inch length for substantial cooking area. Smaller units like the Ooni Karu 12 focus on specific tasks like pizza, with a 12-inch capacity. Consider the width and depth specs to ensure the grill fits your typical meal size and entertaining habits without overcrowding.

4. Verify material durability

   Construction material affects longevity and maintenance. Stainless steel models like the SPIRE and BODEGA offer durability and a sleek appearance. The SPIRE is explicitly noted for durable materials suitable for serious cooking. The Nexgrill features a black finish, which may require different care. Material choice impacts resistance to weather and heat. Check the attributes for material type to ensure the grill withstands your local climate and usage frequency without rapid degradation or excessive upkeep requirements.

5. Review included accessories

   Included accessories add value and functionality. The Ooni Karu 12 comes with a pizza stone, essential for high-heat baking. The BMMXBI set offers replacement stones for Ooni Karu 16 owners, highlighting the importance of compatible parts. The Nexgrill includes a griddle insert, expanding cooking options beyond standard grilling. Check the included accessories list to see what comes with the unit. This helps you avoid additional purchases and ensures you have the necessary tools for your specific cooking goals from day one.
