There’s no denying that eating barbecue is a sensory experience. The smell as it comes off the pit, and the sight of the smoke ring as you slice into it are part of what makes this hobby so satisfying.

The bark is an integral part of this experience. A flavorsome, licorice black bark is often the reason you and your guests will be coming back for a second, even a third helping of smoked meat.

A consistent, delicious bark is one of the hallmarks of a true pitmaster. But the skills to produce a good bark shouldn’t take you a lifetime to master.

But what exactly is bark? Why is it so damn important and how do you make sure you get a delicious bark every time you smoke?

What is bark?

Bark is an incredibly tasty crust that forms on your smoked meat.

It is actually the result of some complex chemical reactions that have happened throughout the cooking process. Specifically, the Maillard reaction and polymerization.

In basic terms, bark forms when the surface of the meat is exposed to heat and oxygen. When the meat is also exposed to smoke, the bark will become a dark, licorice color. Without exposure to smoke, the bark will be more of a dark red, mahogany color.

T-ROY COOKS has an excellent in-depth video that looks at how to get a bark.

Contrary to common belief, caramelized sugar is not responsible for the formation of the dark crust on the meat.

The optimum cooking temperature inside the cooker should be between 225 – 250°F. However, table sugar does not start to caramelize until it hits 300°F.

Bark still forms when you use sugar-free rubs, so you know something else is going on.

As the meat is cooking, the surface begins to dry out. Proteins on the meat’s surface bond together and form polymers. This is called the Maillard reaction. The result is a hard layer on the surface of the meat, called the pellicle. If you applied a spice rub to your meat, it will form a crust just on top of the pellicle.

And there you have it – in more common terms, the bark.

How does your rub affect the bark?

The ingredients in your rub that are water-soluble or fat-soluble have specific roles to play in forming the bark.

As the meat smokes, the ingredients in the rub that are water-soluble, such as salt and sugar, will dissolve either in the moisture of the meat or the moisture in the smoke. The dissolved salt molecules will go on to penetrate the meat.

The undissolved ingredients of the rub will remain on the surface of the meat and start forming a glaze. As the meat continues to cook, fats in the meat will render. At this point, the fat-soluble ingredients of your rub will dissolve also.

The glaze, which contains dissolved ingredients, along with the remaining undissolved herbs and spices, combine to form a pasty substance on the surface of the meat.

As the cook progresses and the pellicle forms, these ingredients on the surface will dry out and form the spice crust. The pellicle along with the crust is your delicious bark.

Did you know? According to Prof Greg Blonder of Amazing Ribs.com, salty and acidic rubs will tend to form a bark faster.

This may sound like a potential shortcut, but don’t get too excited. While the bark may initially form quicker, this does not improve the quality of the bark you achieve by the end of the cook.

What are the basic ingredients in a rub?

Now we know the importance of a good rub to form a bark, but what kind of rub should we be using to produce a good bark?

While there are countless variations of meat rubs, the basic ingredients should include salt, pepper, sugar (except when cooking beef), and paprika. Often there is onion and garlic powder in the mix.

The specific spices you include in your rub and how much you use will affect how thick your spice crust is. This is an important consideration when planning out your bark recipe.

How much chili can you handle in your spice crust? Creating your own rubs is a great way to experiment with different variables and see your preference.

Or you can go the store-bought route, in which case we have you covered with our line of Smoke Kitchen bbq rubs.

Personally, I like to keep a few good rubs stocked in the pantry for when I don’t have the right ingredients to make my own rub (or when I”m feeling lazy).

How does smoke affect the bark?

Smoke is also a key factor in the creation of the bark. The longer your meat is exposed to the smoke, the darker it will become as more smoke particles stick to the glaze.

A piece of meat that has been smoked for a long time (12 or more hours) may appear burnt. On closer inspection, however, the bark on this meat should be glossy, not dry and charred. The meat, in fact, will not taste burnt. On the contrary, it should be delicious!

After rub, smoke is the second most important factor to achieve a good bark.

“The longer a piece of meat is exposed to the smoke, the darker the bark will be. It just happens.

A piece of meat that’s smoked for about 15 hours will almost look burnt. But it’s not. If it’s done correctly, good bark is a highly coveted piece of the meat.

The smoke particles stick to the glaze and change the color of the original rub. “

This is why you don’t want to wrap meat too soon, as the bark will not have had a chance to set.

How does temperature affect the bark?

One of the basic principles of successful barbecuing is temperature control. This principle also applies when creating a great bark. If the temperature is too low, the bark will not form. If it is too high, you will char the meat.

A good temperature range to aim for is around 225-250°F.

Around half way through the cook, moisture starts to evaporate from the meat, thus cooling the meat, and slowing the cooking. This is referred to as the “stall”.

Eventually, after enough moisture has evaporated from the meat, the rub will dry out and the Maillard reaction will begin. The chemistry of the outer layer of the meat will change, creating the pellicle.

If the temperature is too low, the Maillard process will not happen, so maintaining adequate temperature throughout the cook is vital.

How does fat content affect the bark?

As is the case with the temperature, when it comes to the fat content of the meat, balance is required to form a great bark. It is not simply a case of the more fat, the better.

Fat is necessary to form the bark, because the fat soluble components in the rub dissolve and hold on to the spices, forming the crust.

If your meat is too fatty, however, it could hinder the creation of the pellicle, by obstructing the access of heat and oxygen to the proteins on the surface of the meat.

In light of this, it is advisable to trim off any excess fat. Aim to leave just enough fat to render and provide that nice glossy glaze for the spices, smoke, and dissolved salt and sugar to stick to.

This is also why we generally recommend meat with a fat cap like pork butt should be smoked with the fat cap pointing down, or in the direction of the heat sauce.

How does moisture affect the bark?

To form a bark, there must be some moisture present so that the water soluble ingredients can dissolve. The moisture that is naturally in the meat and the smoke is usually adequate.

Therefore, you don’t need to go crazy basting of your meat throughout the cook. Too much moisture will in fact stop the bark from forming, because the surface of the meat needs to dry out in order for the Maillard reaction to start.

Tips & Tricks to guarantee a good bark

Now that we know how and why bark is formed, what steps can we take to make sure we get a good one next time we smoke some meat?

Here are some tips:

  • As discussed, remove any excess fat from your meat. Around a ¼ inch to ⅛ inch of fat on your meat is all you will need.
  • Don’t sit your meat in a pan while it’s on the smoker. This will reduce the airflow and prevent the surface from drying out. Sit it on the grill plate.
  • Sugar can char and cause your bark to be bitter in taste. If you are a beginner, you could try applying sugar in the form of a baste during the latter stages of the cook.
  • Don’t wrap the meat in foil to speed up the cook during the stall. This will damage your bark. Due to the steam that accumulates inside the foil, you could end up with mush instead of a bark.
  • If you do plan on wrapping, wait until the bark has had enough time to develop.
  • Some pitmasters use butcher paper through the stall, around the point when the temperature is 160°F, and report no ill effects. Others, however, swear that wrapping anything around your meat will kill your bark. We have an article that explains the paper vs foil debate.

  • Don’t mop or spritz for the first two hours of the smoke. Not only are you potentially washing off your rub, but you may also be hindering the formation of the crust. The crust will have started to form after a couple of hours. It is safe to baste, mop, or spritz after this has happened.
