Does Bioethanol Create Smoke or Odours? Everything You Need to Know

If you’re considering switching to bioethanol fuel for your indoor fireplace, garden fire pit, or tabletop burner, one question probably comes to mind:

Does bioethanol create smoke or unpleasant odours?

Let’s clear up the confusion and explain why bioethanol is one of the cleanest fuels available today.

Why Bioethanol Burns Clean

Bioethanol is a renewable, plant-based alcohol fuel, made from natural sugars in crops like corn, wheat, and sugarcane.

Because it’s a pure alcohol, bioethanol burns completely, producing only:

• Water vapour

• Small amounts of carbon dioxide

Unlike wood or coal, there’s no smoke, soot, or lingering smell — provided you use high-purity bioethanol.

What Causes Smoke or Odours?

If you notice smoke or odours while using a bioethanol burner, it’s usually due to one of three things:

1. Low-quality fuel – Cheaper bioethanol can contain additives or impurities. These impurities can produce a slight smell or light smoke.

2. Overfilling the burner – Too much fuel can spill or burn unevenly.

3. Improper ventilation – Although bioethanol burns cleanly, a completely sealed room may intensify odours if any fuel vapours escape.

✅ Using premium fuel like Black Rock Grill Bioethanol avoids these issues and guarantees a clean, enjoyable flame.

Benefits of Smoke-Free Bioethanol Flames

Using high-quality bioethanol fuel comes with several advantages:

• No soot – Your fireplace, burner, or table remains clean.

• No lingering odours – Great for indoor use, apartments, or spaces without ventilation.

• Low maintenance – No ashes or messy residue to clean.

This is why bioethanol is perfect for modern homes, restaurants, and outdoor entertaining.

Tips for a Clean Burn Every Time

To ensure a smoke-free experience:

1. Always use high-purity bioethanol

   • Example: Black Rock Grill Bioethanol Fuel is refined for clean combustion, 96% purity.

2. Fill burners correctly
