Features to Consider Before Buying

Firstly, note that there are various alcohol fuels as highlighted above. You have to understand how they work as well as the risk associated with them. The common fuels on the market include denatured alcohol, rubbing alcohol, pure methanol and pure ethanol. We have detailed them below.


This is probably the most important feature of them all, you want to mae sure you are safe whenever you’re using fuel. There are different types of alcohol, and they all have different performances, which we will explain below.

However, if you’re inexperienced you want to use alcohols with less performance, they will still work, but you’ll be safer, and safety always goes first.

Denatured Alcohol

This type of alcohol is relatively cheap and commonly available in hardware stores. You can either buy it before you embark on your journey or visit the hardware stores in close proximity to your outdoor locations.

Denatured Alcohol

But to stay on the safe side, we reckon you order up front before taking your trip. Choose from our carefully selected denatured alcohols reviewed below. The contents of a denatured alcohol often include ethanol with added methyl alcohol.

It is not fit for a human to consume it because it can be adversely detrimental to your health. Moreover, it can contain the notoriously toxic methanol with approximately 16% concentration, methyl acetate 1% and methyl ethyl ketone 1%.

But among these contents, ethanol is often less than 50%, which then make this choice of fuel environmentally unfriendly. Nonetheless, it is a recommended alcohol fuel for your stove.

Concentration of Ethanol

In addition to the generic denatured alcohol with an ethanol content of less than 50%, there is a green denatured alcohol fuel, which contains a high concentration of ethanol and lower content of additives.

green denatured fuel

The higher concentration of ethanol renders the fuel highly capable of providing extremely hot flames. Furthermore, since ethanol burns cleaner, the higher concentration means your stove will burn more effectively, thus eliminating the uncomfortable soot and poisonous fumes as experienced from other fuels such as methanol.

Pure Ethanol

With this alcohol fuel, you must be prepared to pop out a large sum of money. It is relatively expensive compared to the denatured alcohol mainly because of its purity; but, it is very scarce to find.

Notwithstanding its expensive price tag and scarcity, it is a recommended fuel for your travel because of its eco-friendly advantage and lack of toxicity. If environmental friendliness is your priority, you would then certainly opt for this type of fuel rather than other harmful alcohol fuels.

Pure Methanol

Methanol burns more quickly than the ethanol in a stove. However, the dangers associated with it out-number the ones associated with ethanol and other fuels.

Yellow HEET Burning

It has a high vapor pressure and this makes it more usable and suitable for cold temperatures when used as a fuel. In actual fact, this high vapor pressure prompts many people to choose this fuel over others.

But, the downside is that this fuel is more toxic and dangerous than others, more especially when in contact with the skin and mucus membranes. It can turn into formaldehyde in the body, which is a dangerous chemical.

Methanol is interchangeably called methyl alcohol. It can usually be spotted in a yellow HEET bottle if you stay in the United States. You are urged to only buy this alcohol fuel if you’re going to be very careful with it because of its associated dangers.

Pure Isopropanol

Here’s another alcohol fuel for your stove. It can be spotted by a red HEET bottle widely available in the US. The fuel burns with yellow and sooty flames that are hot enough to cook.

Red HEET Burning

And, unlike methyl alcohol, it is not extremely toxic. You can readily find it at convenience or gas stores or order it from online retail stores.

Rubbing Alcohol

This fuel often contains 70% of isopropanol and the remaining percentage goes to water. Despite the addition of water, it is burning almost the same with the pure isopropanol.

They provide the highest heat content, but not recommended based on their bad sooty. Having detailed to you about the various alcohol fuels, you are now well positioned to know which one can be best for you. Let’s now delve into the selected alcohol fuels that we reckon could be your best companions in your next outdoor trip.

Top Alcohol Fuel Reviews

The following types of alcohol fuels are what we consider the most practical and user friendly for any experience. None of them is pure methanol, as it has a higher performance, meaning a bigger risk for you. Safety is a concern too, and so we chose carefully.

  • I want to buy the fuel from Klean-Strip for use on the next backpacking trip but I am worried about how I will transport it. Can I put it in a metallic flask and stick in into my backpack. Will my flask be a safe way of transporting it or do I have to get a special container to carry it in?

  • You can place them in those small flask bottles made of plastic that can be bought from the liquor store. This container fits your outside backpack pocket, so its convenient to take. Besides, you don’t need to bring so much fuel.

  • How high does the flame from the Real Flame Gel Fuel burn? And, can I use it to roast some simple eats, say marshmallows? Is the fuel safe for such tasks or will it be unhealthy to roast my marshmallows on the flames of this fuel?

  • The height of the flame is around 4-6 inches tops. And it’s a no-no if you’re going to toast some marshmallows. The marshmallows will taste like “fuel pops” – old joke from my buddies…but really, it will taste funny.
