Let’s be honest. No one wants to serve dry barbecue.

And no one wants to eat it.

So it makes sense that since the caveman days, we’ve been slathering sticky mop sauces and spritzing our barbecue with liquid.

It seems like basic math. Add liquid = less dry meat.

But like everything in barbecue, it’s not that simple. Mopping and spritzing can be an effective tactic when used correctly. But it can also wash off the flavorful bark you’ve spent hours trying to build.

In this article, you’ll learn why and how to mop or spritz.

How are Mopping and Spritzing Used in BBQ?

Mopping and spritzing are techniques for applying moisture to meat as it cooks. The main difference between these two techniques is how the moisture is applied.

As the name suggests, mopping involves adding moisture with a brush or “mop.” You’ll also hear people refer to the sauce being applied as the “mop.

Spritzing involves spraying moisture onto the surface of the meat with a spray bottle.

As well as keeping everything moist, you can use different liquids to add layers of flavor to the meat you are cooking.

Mopping and spritzing your meat will result in a slightly darker, softer crust or bark. The crust will also attract more smoke, resulting in a smokier flavor. Your meat will also appear a little plumper and juicier from the outside.

However, even though it may seem that you have nothing to lose and everything to gain by mopping your meat, not all pitmasters are a fan of this technique.

More about this controversy later.

For Grillers or Smokers? A Look At The History of Mopping and Spritzing

People have been mopping and spritzing their meat for a long time, and the technique is mentioned in the history books of many cultures.

Interestingly, the term ‘mopping’ even has historical origins. The term first appeared when US President Johnson’s favored pitmaster, Walter Jetton, cooked up meat for the masses on an enormous, 40 square foot open air grill.

To stop the meat from drying out, he used a mop to moisten the meat.

Mopping and spritzing can be used for both low and slow and grilling.

Interestingly, despite historically having been a technique used for grilling, in recent times, they have become more closely associated with cooking low and slow.

The Controversy

Like almost everything when it comes to barbecue, there is disagreement about when you should mop or spritz and how effective it is.

While many pitmasters don’t question the importance of mopping and spritzing, there is a vocal minority of the smoking community who believe there is no need to mop or spritz at all.

More than that, they claim that the technique jeopardizes the flavor of the finished product.

They argue that a watery mop could wash off any rub or spices that have been added to the meat and damage the valuable bark.

Over longer cooks, regularly opening the lid to apply the sauce (which is usually cold) will also lengthen the cooking time, which some see as a disadvantage.

There is more than meets the eye when it comes to mopping and spritzing.

Let’s find out more about the technique, and then you can decide for yourself if you want to add it to your toolkit.

What Happens When You Mop or Spritz?

There are six different factors you need to consider.

1. Flavor

It is often assumed that one of the main reasons you mop or spritz is to add flavor. But this is not necessarily the case:

  • While the sauce you mop or spritz with will have a flavor all of its own, it will not have as much flavor as the rubs you may have put on your meat.
  • So if your watery mopping sauce washes off some of the rub you have applied, you will lose flavor.

However, if you use a thicker, stickier sauce to mop with, you will not face this problem, and you will still add flavor to your meat.

Clearly, the same does not apply when spritzing, as the liquid needs to be thin enough to be sprayed out of a spray bottle.

2. Cooking Time

It is no secret that mopping or spritzing your meat will increase the cooking time.

The sauce itself is the main culprit for this increase. The added moisture and the cool temperature of the sauce will cool the surface temperature of the meat.

This can help you avoid drying out your meat, especially if your cooker is running hot.

The impact will depend on how hot and fast you are cooking.

  • If you are cooking at high temperatures over a short time, mopping or spritzing will not have a great effect on the cooking time at all.
  • When cooking low and slow, you could notice an increase of 10-20% of cooking time.

3. The Crust

Over-spritzing or mopping can result in a less crispy crust, as you will be replacing the moisture lost to evaporation.

However, the addition of some oil and sugary liquids to your mop or spritz sauce will aid in the browning of the meat’s surface.

The browning occurs as the sugars in these ingredients caramelize during cooking. This will work particularly well when your cooking temperature is quite high.

If you are cooking something that already has fatty skin, then the addition of a water-based sauce will not improve the quality of the crust.

It will make the skin limp and hinder the formation of that brown, crispy surface we are after. When cooking meats such as chicken or duck, it is often best to let it be, and let the skin’s natural properties work their magic.

So, in most cases, it comes down to personal preference as to how you like your crust. Crispy and crackly? Or, sticky and brown? We will leave the answer to that question up to you.

4. Smoke and Smoke Ring

Mopping and spritzing will aid in the formation of a smoke ring.

Mopping and spritzing will help form a smoke ring because the moisture you add to the meat’s surface attracts smoke.

This allows the sodium nitrite in the smoke to sink into the meat and react with the myoglobin. It is this reaction that leaves us with the highly prized pink ring just near the surface of the meat.

5. Shrinkage

When you mop and spritz, you replace some of the moisture lost during the cooking process.

While it will not make a great difference to the size of the meat, your meat will look plumper and less dried out when it is done.


If you are not careful with hygiene when mopping your meat, there is a slight risk of contaminating it.

For instance, if you have mopped the meat before it is fully cooked, you could have picked up microorganisms from the meat. If you use the same mop, you may be spreading the bugs.

Similarly, if you use the liquid you marinated the meat in as a sauce, you will again spread microbes onto the meat when you mop it.

However, if the meat is cooked above 155°F, most nasties will be killed.

So when mopping, take the time to think about where your mop has been, where the liquid you are using has come from, and what temperatures you will be exposing the mopping liquid to. This way, you can avoid any sickness resulting from the bugs in raw meat.

To Spritz or Not to Spritz

Now we know the technicalities of what goes on when we mop and spritz our meat. But in real terms, how does this affect the outcome?

All Things Barbeque decided to cook ribs head to head. One with spritzing and the other without.

You can see the video here if you are interested in how things panned out.

Spritzing vs Not Spritzing Ribs | Tips & Techniques by All Things Barbecue

In the end, both cooking methods produced a tasty result. However, there were some differences. And which method each individual prefers is a matter of personal taste.

  • Texture – For one, the bark on the un-spritzed ribs was crispier and dryer. Whether you prefer the crust crispy or a little softer is up to you. The spritzed meat was also visibly plumper than the un-spritzed version.
  • Flavor – The spritzed meat ended up with a more subtle in flavor than its un-spritzed counterpart. It appears that the zing of the spice rub was muted by the addition of the spritz. Again, whether you prefer your ribs zingy or more subtle is a matter of personal taste.
  • Cooking Time – Probably the most notable difference between the two options was the cooking time. The meat that was spritzed throughout the cooking process ended up taking about an hour longer to cook that the ribs that were left dry.

Tips For Mopping and Spritzing

  • To help form a sticky dark bark, use ingredients in your mopping sauce that have a high sugar content. Apple juice, a spirit such a bourbon, along with some olive oil makes a simple mopping sauce that will leave you with a great bark.
  • Wait until a crust has started to form before you start mopping. If you wait about 90 minutes before you start mopping or spritzing, you will tend to lose less of your rub than if you start mopping earlier into the cook.
  • Immediately after you have flipped the meat, mop the side of the meat facing up while it is still sizzling and hot. This way the mopping sauce will have a chance to sit and soak into the meat.
  • Some pitmasters prefer to spritz as they feel this won’t disturb the surface of the meat as much as mopping would. Bear in mind, if you spritz then flip the meat immediately, you will lose some of the rub you have put on the surface of the meat.
  • If you are cooking something that features a smoky flavor such as bacon, mopping will ensure that the maximum amount of smoky flavor is taken up by the meat. Once the surface of the meat has dried out, it will stop taking up smoke.
  • You may also consider warming up the brush and mopping sauce if you are worried about cooling the surface of the meat.
