Best Liquid Fuel · 1 of 3
ROUNDFIRE Premium 6 x 1 Liter

- 96% ethanol, 6 x 1 liter
- Smokeless, odorless, ash free
- Spirit burner compatible
Our take
The best pour-in fuel for open-cup alcohol burners.
Why it made the shortlist
Roundfire Bioethanol is a six-liter pack of six 1-liter bottles of 96 percent ethanol. The listing calls it smokeless, odorless and ash free, and names fireplaces, burners, spirit burners and stoves as uses.
Against the Swissmar gel it pours easily and can refill an open burner.
It suits campers with spirit burners and anyone who wants a clean-burning plant-derived fuel. The six-pack means a season of fuel.
What works
- High-purity 96 percent ethanol
- Clean-burning with no ash
- Six bottles in one pack
- Plant-derived fuel
Watch out for
- Bulky for backpacking
- The catch
- Six liters is heavy and costly to carry on foot.
