The Konro grill is made out of diatomite bricks. This makes the grill strong and more fire-resistant. It also helps circulate heat more evenly for an amazing cooking experience. Since it allows the charcoal to start and burn for long periods of time, paired with the high-heat capacity of the charcoal, you can cook delicious barbecued food in no time. The Konro grill also adds a smoky flavor to your food, giving it a delicious aroma.
