Overview
The rundown on the Masterbuilt Gravity Series 800 Griddle
The Masterbuilt Gravity Series™ 800 is the ultimate charcoal grill + smoker + griddle combo for serious Australian backyard entertainers who refuse to compromise on flavour. Powered by the patented GravityFed™ vertical charcoal hopper — holding up to 4.5 kg of lump charcoal or 7 kg of briquettes — it delivers authentic charcoal taste with the precision of a digital control system. Hit 107°C in just 8 minutes for long, low-and-slow smoking sessions, or crank it to a searing 371°C in under 14 minutes for steakhouse-quality crust on your best cuts. The DigitalFan™ maintains rock-steady temperatures throughout, while built-in WiFi and Bluetooth let you monitor and adjust from the Masterbuilt app — right from your backyard deck chair.
Across its 5,160 cm² (800 sq in) of total cooking space, the Gravity Series 800 handles the full spectrum of Australian BBQ and outdoor cooking. Slow-smoke a whole brisket or pork shoulder overnight using the reversible cast-iron grates in their raised position, then flip them flat and sear thick-cut ribeyes at full blast for the perfect Maillard crust. The included flat-top griddle insert opens up a world beyond the grill — think smash burgers, crispy bacon and eggs for a crowd, caramelised onions, or fajitas sizzling away while your guests watch on. Two porcelain-coated warming and smoking racks keep sides and bread perfectly warm without drying out, while the folding stainless-steel front shelf gives you essential prep space without cluttering your alfresco kitchen setup.
What sets the Gravity Series 800 apart from ordinary charcoal kettles or offset smokers is its seamless marriage of old-world charcoal flavour with new-world connectivity. The Masterbuilt app lets you set temperatures, track up to four simultaneous meat probe readings, view cook graphs, and explore guided recipes — no more hovering over coals or guessing when the brisket is ready. Powder-coated construction stands up to Australian sun, coastal humidity, and everything in between, making this a backyard centrepiece built to last season after season.
