What Makes Vinachaki Charcoal Different?

Vinachaki’s sawdust charcoal briquettes are made through a strictly controlled process — from raw material selection to molding and carbonization.

Each briquette is crafted with selected hardwood sawdust, high compression, and precise carbonization time, ensuring:

  • Long burning duration

  • Stable and strong heat

  • Low ash content

  • High fixed carbon ratio

This blend of Vietnam’s charcoal-making tradition and modern iron kiln technology allows Vinachaki products to meet the strict expectations of premium markets like Korea, Japan, and the Middle East.

1. Production Process

Stage Grade VIP Grade A
Raw Material Selection Only core wood from natural hardwood logs (fallen trees, dry branches, deadwood). No softwood, no fresh-cut, no furniture scraps. 

➤ Dense & heavy → burns longer, less ash.

 Mix of 3 sources: same hardwood as VIP, expired fruit trees, and furniture wood scraps. 

➤ Medium density → moderate burn time, slightly more ash.
Chipping & Crushing Controlled process – logs are chipped and crushed under supervision for uniform particle size. Grind all material types together – less control, varying density.
Filtering ✔ Remove bark

✔ Remove plant fibers & moisture pockets

✔ Remove fine dust & impurities. 

➤ Longer burning, low ash, stable heat.

 ⚠ Remove only basic impurities.

➤ Shorter burn time, more ash, less heat consistency.
Molding 4 logs per minute.

✔ Glossy surface

✔ Solid and heavy structure

✔ Dense sound when tapped

✔ No break under pressure.

 7 logs per minute.

✘ Not shiny

✘ Lighter structure

✘ Softer sound, may break under strong pressure.
Carbonization 1 day in iron kilns

→ High carbon content (> 90%), clean combustion.

 1 day in iron kilns or 7–10 days in brick kilns

→ Lower carbon content (> 85%), high-moderate performance.

This process difference explains why Grade VIP has superior density, longer burning time, and cleaner heat, while Grade A offers solid performance at a more economical price.

3. Performance Comparison

Heat Stability and Longevity

Both VIP and A grades provide strong, stable heat. However, VIP briquettes, made in iron kilns, have a higher carbon density and burn more evenly for extended hours. Grade A offers a similar performance but slightly less density, and is ideal for restaurants balancing quality and cost.

Ash and Clean Combustion

  • VIP: < 3% ash — clean, low maintenance, pure flavor.
  • A: < 6% ash — still clean and efficient for daily commercial use.

Appearance and Structure

VIP briquettes have a glossier, smoother surface with a deep black tone — a result of high-temperature iron kiln firing. Fine cracks may appear due to the intense carbonization process, but these are natural and do not affect performance. They actually indicate a dense, well-carbonized core.

Sawdust Charcoal Briquettes Grade VIP

A briquettes have a more matte surface with fewer visible cracks, especially those made in brick kilns. Their clean and uniform look makes them perfect for everyday BBQ operations.

Why Iron Kiln Charcoal Is Premium

The iron kiln system used for Grade VIP (and some Grade A batches) ensures:

  • Higher carbonization temperature → denser structure
  • Better oxygen control → uniform heat
  • Reduced smoke and odor during ignition
  • Longer burning, cleaner ash

Iron Kilns

This technology delivers charcoal with superior stability, minimal impurities, and professional-grade performance suitable for luxury restaurants and resorts.
