What Is Alcohol Stove Fuel?

Stove-Fuel-Basics

  • Alcohol stove fuel comes in two principal types: ethanol and methanol.
  • Ethanol (ethyl alcohol or grain alcohol) is what we consume in beer, wine, and liquor. Pure ethanol burns the cleanest of any fuel, but is expensive and hard to find.
  • Denatured alcohol (methylated spirits) is ethanol that has been rendered undrinkable (and thus exempt from alcohol taxes) through the addition of methanol and other chemicals.
  • When shopping for denatured alcohol, look for a minimum of potentially toxic additives; versions sold as marine stove and lamp fuel are a good bet. Avoid varieties that leave a solid residue after burning.
  • Methanol (methyl alcohol) is commonly used as gas-line antifreeze for engines. Gas stations sell it under the brand name HEET.
  • Methanol contains 30 percent less energy than ethanol; you need more of it to boil the same amount of water.
  • Methanol and denatured alcohols are toxic. Keep your stove and fuel separate from your cookware to prevent contamination.
