Quick answer
The Ooni Karu 12G is the best way into the Karu family. It keeps all the multi-fuel versatility of the Karu 12 and adds a glass door and built-in thermometer that let you read the fire without opening the oven: you gain control without pushing the price too high or growing the size. It's for the wood-fire lover who wants a bit more control without jumping to large format; anyone needing large pizzas or who prefers the simplicity of pure gas should look elsewhere.
All the multi-fuel versatility of the Karu 12, now with a glass door and built-in thermometer to read the fire without opening the oven.
The Karu 12G is the natural evolution of the 12: same compact format, same wood and charcoal flavour, same optional gas ignition, but with an upgrade you'll appreciate every bake. The glass door and built-in thermometer let you watch the pizza and read the interior temperature without opening up, so heat stays stable and cooking is more predictable.
For the kamado cook, that thermometer speaks a familiar language: just as you watch your ceramic's probe, here you read the oven at a glance and adjust the fire before it drifts. It's the detail that makes managing wood more controlled without losing the artisan soul.
It's still 12 inches, so it keeps its virtue as a discreet companion that won't crowd the terrace. It delivers a generous individual pizza with real fire flavour, leaving large format and long cooks to the kamado. Anyone who wants the Karu experience with a touch more control will find their model here.
The best way into the Karu family: the built-in thermometer eases control without inflating the price or the footprint.

Frequently asked questions
How does it differ from the standard Karu 12?
It adds a glass door and built-in thermometer, letting you see the pizza and read the interior temperature without opening up, for steadier, more predictable cooking.
What fuels does it take?
Wood and charcoal as standard, and gas via an optional adapter sold separately. The thermometer works in any fuel mode.
Is it easy for a beginner to control?
The thermometer helps a lot: it gives a temperature reference without having to open and lose heat, reducing the typical mistakes of someone new to wood.
How do you clean the stone and the glass?
Dry-brush the stone and burn off stains with the oven's heat. Clean the glass cold with a damp cloth, no abrasives.
Does it make sense alongside a kamado?
Yes: it brings fast 500 °C wood-flavoured pizza and a familiar temperature control, while the kamado handles smoking and slow cooking.
