Is Jameson Flammable?

This article will answer the following question: “Is Jameson Flammable?”. We will discuss if Jameson Irish Whiskey is flammable or not, how easily it can catch fire, and how much of a hazard it is.

Is Jameson Flammable?

It’s not much flammable but can catch fire. Jameson whiskey has 40% ABV, but around 50% is required for a distilled liquor to ignite easily/ readily. However, the drink’s flashpoint is considerably low.

This means that flammable vapors can arise from Jameson under mild conditions, and a mist of a highly flammable substance (alcohol) would be formed, which is dangerous if there’s a naked flame close by.

What is Jameson?

Jameson is a brand. Its most popular label is called Jameson Irish Whiskey, made from a blend of grain whiskey and single pot still whiskey.

It’s made using a mix of malted and unmalted Irish barley, harvested in the same region as the distillery, in the city of Cork, in South-West Ireland.

Unlike other traditional Scotch whisky distillers, Jameson’s barley is not malted firing the kiln with peat, but natural gas. This way the distinct peat flavor is not present.

What is whisky?

Whiskey is a type of distilled liquor made from fermented and/or raw grains, which can be barley, corn, rye, and wheat. After, the liquid is put on wooden casks to age and retain flavors.

The first distillations were first made by Greeks in Alexandria, in the first century of the common era/ after Christ. Alcohol was not going to be distilled for more than a thousand years, in the 13th century.

Whiskey itself was only discovered more or less in the year 1400.

There’s no single definition of what whiskey is, but we can point out some differences according to its ingredients, alcoholic content and quality. Here’s some:

  • Single malt whiskey: this whiskey normally bears the distillery’s name. It uses only one kind of malted grain, but many casks can be used.
  • Blended malt whiskey: a whiskey made by a mixture of a single malt originated from different facilities.
  • Blended whiskey: a mix of different whiskey liquors, which can come from many distilleries. 
  • Cask strength: this kind is not diluted after distillation, so it gets much more strong (more alcohol). It’s bottled directly from the cask.
  • Single cask: Only one kind of cask is used. The result is whiskeys which the taste varies according to each batch.

The flavors come from the ingredients, the fermentation process, the distillation, and the oak barrels. Most flavors are a class of chemicals called aldehydes.

The perhaps most common of them is called acetaldehyde, a compound that provides a fruity flavor. It also plays a major role in giving us hangovers.

How much alcohol does Jameson has?

Jameson Irish whisky has 40% ABV (80 proof). It’s the most common alcohol strength among whiskies, one that gives a sufficient “burning” sensation on the mouth.

This sensation has nothing to do with fire whatsoever. It appears after the liquor engulfs our taste buds, interacting with nerves in our mouths and throats, making our bodies believe we’re ingesting something hot.

What is ABV?

ABV is an abbreviation for alcohol by volume. It is a standard measure to write down how much ethanol (common alcohol) ratio is contained in a beverage.

It’s defined as the quantity (in ml) of pure ethanol in 100ml of the drink, at 20ºC (68ºF). The ABV number gives us information on how much alcohol a beverage has.

It’s important to note that ABV is not the same as volume fraction, a property commonly used in Chemistry. 

A drink that has, let’s say, 50% ABV doesn’t necessarily contain 50ml of alcohol in 100ml of the whole drink, but a little bit more. This is because the volume of a mixture changes when we mix two different things. But this difference is not big, no more than 2.5%.

Can Jameson burn?

Yes. Even though it’s not very flammable because it’s mainly made of water, the amount of alcohol within shouldn’t be taken for granted. 

Jameson’ flashpoint is around 26ºC (79ºF). 

Flashpoint is the lower temperature at which a liquid starts evaporating spontaneously. It is different from the boiling point, which is the temperature something starts to evaporate greatly.

A low flashpoint means that a glass of Jameson starts to evaporate in mild conditions. Because the vapors contain alcohol, the vapor is flammable, so attention is required if a good amount of it is exposed to the air in a confined room.

When a flammable substance reaches a vapor state, it also reaches the most flammable state. But don’t be afraid, it’s not something so hazardous. You can keep drinking it normally.

Although, there’s a considerable fire risk in drinking a distilled beverage while smoking, or vice-versa. If this is something you do often, consider doing it outside or at least leave windows opened for better ventilation.

Jameson is not expected to burst in flames, but it’s not impossible for it to happen. A combination of whiskey, naked flames, and clothes (or furniture) could be catastrophic if there’s a source of ignition close by.

Can Jameson catch fire easily?

No. Normally, beverages are only considered flammable if they have 50% ABV or more. If flames reach a glass of Jameson, it wouldn’t burn right away.

A beverage like Jameson would only catch fire if is tossed into big flames, else if it is heated first. But the liquor is normally consumed cold, so this hazard gets even lower.

Also, due to its low flashpoint, flammable vapors would arise from a cup of it, and they could catch fire. But only if there’s a naked flame close by. Auto-ignition is not expected.

But the thing is, alcohol can evaporate much easier than water. So if a beverage below 50% ABV is mildly heathen, the alcohol would just evaporate before burns. This doesn’t mean there’s no hazard.

Many people have Jameson’s whiskey on rocks. The colder the beverage is, the less flammability it presents. So if you’re still worried about your safety, that’s something you can do.

And as we said before, beware if you drink and smoke at the same time. Being in a room with good ventilation or outside is the best choice.

Examples of ignition sources

An ignition source is anything that generates flames, heat, or sparks. Here’s a list:

  • Open flames;
  • Cutting and welding;
  • Hot surfaces;
  • Heat;
  • Lightning;
  • Smoking;
  • Spontaneous ignition;
  • Friction;
  • Static electricity;
  • Electrical Sparks;
  • Stray Currents;
  • Ovens, furnaces, and any heating equipment;
  • Pyrotechnical materials.

Is Irish whiskey the same as bourbon?

Bourbon is typically crafted in the United States, while Irish whiskey is only made in Ireland. 

Irish whiskey primarily uses barley malt with the occasional cereal grains blended in, while bourbon mash typically contains 51% corn or more.

Also, Scotch is normally distilled twice, while Irish whiskey is distilled three times.

Bourbon is a type of oak barrel-aged American whiskey, a distilled liquor made mainly from corn (at least 51%).

Are Jameson’s cocktails flammable?

Overall, they are not. The more diluted a distilled beverage is in water, juice, or any other non-alcoholic product, the less flammable it will become. 

Jameson itself does not present high flammability when under normal conditions because more than half of it is water.

It might sound weird that the liquor is diluted in water, but this is not made to trick the buyer or save money, it’s required so the beverage becomes more palatable.


Jameson does not possess high flammability, it will not ignite spontaneously and a lit match would not ignite a glass of whiskey on rocks. But it can catch fire.

If it’s heated enough, even in low temperatures like 30ºC, flammable vapors will be unleashed, which can ignite readily if there’s a source of fire near, and if the room has poor ventilation.

The biggest problem is not a potential fire on its own, but the other things it can set fire on if eventually burns. This includes: clothes, hair, furniture, cabinetry, or any other available source of fuel.
