At Sumito, nestled in the heart of Wan Chai's QRE Plaza, we are passionate about delivering an authentic and unforgettable robatayaki experience. Central to this commitment is our unwavering dedication to using only the finest Binchotan charcoal. But what exactly is Binchotan, and why does it matter so much?

Binchotan is a unique type of charcoal crafted primarily from oak, specifically *ubamegashi* oak, through a painstaking and time-honored process. Originating in Japan, its production involves a two-stage firing process: a gradual heating to carbonize the wood, followed by a rapid increase in temperature near the end. This intense heat, reaching upwards of 1000 degrees Celsius, transforms the oak into a dense, almost metallic charcoal. The resulting product is virtually pure carbon.

Unlike ordinary charcoal, Binchotan burns at a consistently high temperature and produces very little smoke. This clean burn is crucial for robatayaki. The lack of smoke allows the natural flavors of the ingredients – the delicate sweetness of scallops, the savory richness of Wagyu beef, the earthy notes of seasonal vegetables – to shine through, unadulterated by acrid smoke. Instead, a subtle, almost imperceptible smoky aroma delicately enhances the food. Imagine the gentle sizzle as a skewer of Hokkaido scallops hits the grill, the intense heat searing the exterior while the interior remains succulent and tender. Binchotan's even heat distribution ensures precise cooking, locking in moisture and creating a perfect balance of textures.

The specific type of oak used also plays a vital role. *Ubamegashi* oak is renowned for its density and hardness, contributing to Binchotan's long burn time and exceptional heat output. This allows our chefs to maintain a steady and controlled grilling environment, essential for achieving the desired level of char and caramelization. The snap and crackle of the Binchotan as it heats adds to the sensory experience, creating a symphony of sounds that complement the visual spectacle of the robata counter.

We source our Binchotan carefully, ensuring that it meets our stringent standards for quality and sustainability. While true Binchotan production has its own environmental concerns, we aim to use the most sustainable sources available and balance this with the quality required for the Sumito experience. By using Binchotan, we are not simply grilling food; we are honoring a tradition that spans centuries.

Next time you join us at Sumito in QRE Plaza, Wan Chai, take a moment to appreciate the subtle nuances imparted by the Binchotan charcoal. It is the silent partner in our culinary endeavor, the invisible hand that shapes the flavors and textures of our robatayaki creations. From the moment you step into our restaurant, the aromatic embrace of gently grilling seafood and meats is made possible by the oaky heart of Binchotan.
