How To Equilibrium Cure or Brine Bacon (Calculator & Tool)

So it was a bit of a revelation discovering how to equilibrium cure or brine bacon, it means I had control over the level of saltiness that you taste (rather than guessing with the old covering the bacon with the salt method). I’ve been making my own bacon for about 20 odd years.

I’ve tried dry curing and wet brining with a whole different array of smoking woods and techniques – so to settle in on one’s technique now really is a blessing.

Equilibrium Curing Bacon Calculator Tool (or any Meat Curing)

I created an equilibrium curing calculator to make it simple for anyone

Here is my curing calculator page.

Here is another page (with same tool but other info) on how much with equilibrium curing here as well.

If you’re new to bacon making or equilibrium curing, please read the rest of this post.

Equilibrium curing is something I’ve been using for dry curing meats, like more classic Italian Salumi. It took over the way that I cured bacon or when I do a pancetta style bacon.

Considering that this just really basically is a little bit of a calculation to work out the ratios. Once it’s done and recorded it’s pretty straightforward.

The most important thing you can remember is that the total amount of saltiness will include the pink curing salt (@ the recommended 0.25% pink curing salt quantity to the total weight).

So, for example, you are aiming for 2% total salt to the weight of the meat. Then I would use 1.75% sea salt +0.25% pink curing salt.

Basics of Equilibrium Curing

Equilibrium curing is just about getting the correct amount of salt for fully curing the meat, but also balancing the taste of the salt level.

You basically get to a level where it’s killing most of the bad bacteria, and when you’re adding the pink curing salt I believe this is taking care of the rest.

I’ve found that over about 4-5% is incredibly salty and just about too much to handle.

But I have read that 5% to 10%, is the appropriate level to use for long-term storage of meat. Just like the explorers of the old world, on their voyages across the globe with salt fish or salt pork for instance.

Basics of Equilibrium Brining

Basically the same as equilibrium curing but you adding water to the mixture, so that you can do it in a wet solution. As a guide, I use the 40% water to the total weight of the meat.

Metric system makes this nice and easy.

1 g (gram) = 1 mL (millilitre)


1000g / 1 kilogram = 1,000 mL / 1 Liter

Now this works as long as the container is kind of a tight fit to whatever the meat weight is.

Sometimes it’s worth doing a bit of a test run with the meat and the container to see how much water is necessary to submerge the meat in the brining solution.

Advantages of Equilibrium Curing or Brining

Control of Saltiness

Okay the obvious ones first, if you use in equilibrium curing or brining method you end up controlling the level of saltiness and therefore taste.

For me personally, my bacon is generally dry salt cured at 2.25% total salt (which includes the 0.25% pink curing salt). It really does depend on your perception of saltiness I know a lot of people that love to go a lot higher and a bit less.

Every packet of bacon in the shop, I tend to read the nutritional information on the back, they are normally around 1.0-1.5g per 100g (or 1%-1.5%). Which seems low for me, but I’m not doing commercial bacon (often brined though).

But this is a level that I’m happy with when I making bacon. Quite often I use no sugar, but if I do have a sweet tooth going on ( or am making bacon for others who like a bit of sweetness) then up to 1% sugar.

Can Leave in the Cure or Brine for a Bit Longer

The good old-fashioned saltbox or saturation method is based on leaving the meat in the cure for a day per 2 pounds or 1 kg.

The big problem is that salt penetrates at a different pace, depending on the brand and the shape of the salt. Whilst also the size of the salt, but in comes the wonderful equilibrium curing or brining.

Going by weight not volume is the key.

I have left equilibrium cured bacon in the fridge for an extra five days no problems getting up to 7 to 9 days even. It developed a slight slimy exterior.

I think this had to do with all the spices and herbs that were used in this bacon mix. So I guess what I’m saying is you can leave equilibrium curing for longer, but be aware that it’s not a free license to forget about it for a month.

Disadvantages of Equilibrium Curing & Brining

Precise Equipment is Needed

The key aspects of equilibrium curing are the precision and percentages.

Sometimes when you’re doing the home curing you may be using only 0.5-1.0 pounds of pork belly for the bacon. When you’re doing this you are working in very small quantities. Definitely using the metric system is the easiest when it comes to equilibrium curing or brining.

Investing in accurate digital scales that go down to 0.X decimal places or even 0.XX 2 decimal places is the only way.

This is pretty much a must, and since the price of technology is come down so much. There are a couple of options that I suggest that will do the trick nicely.

Another tip is that you want to be using a reasonably fine salt and spices cure.

To achieve this you can use a manual grinding method or automatic grinding methods like a coffee spice grinder.

What I like to do is place the spice grinder onto the scales, and then I can zero TARE the ingredients as I add them in.

Challenges of Equilibrium Curing

Applying all Equilibrium Cure to Meat

This is probably one of the most crucial steps when your equilibrium curing (for brining it’s easy).

I find using a good-sized bowl is a really good method because you’re holding the cure in one area.

You can use the meat to wipe the surface of the bowl with the meat at the end, to really get all the cure onto the meat, before placing it in the bag.

You can, of course, rub the equilibrium cure into the meat on a wooden board, but I have found through experience that you always end up having some level of cure left on the board rather than adhering it to your meat.

Maintaining Contact of Cure Tightly to Meat With Oxygen

Now I guess in a perfect world I would have my own vacpac for this, but I always ended up borrowing friends gear instead.

I’ve read on some forums guys only using vacpacs for the equilibrium dry curing. I don’t think it’s necessary as long as you pay attention to removing as much oxygen as possible in a ziplock bag.

Currently what I’m really trying to develop is a reusable bag, I dislike the idea of using single-use plastic to do my equilibrium bacon curing.

So the techniques that I have heard about is using sous vide bags made of silicon, which are reusable and washable. And using one large bag and also a small bag with the meat in it. But I can’t report a proper procedure for this yet so watch this space.

So here is my methods are broken down, first equilibrium curing bacon then brining.

Process of Equilibrium Curing Bacon

  1. Calculate Equilibrium Cure (Calculator Tool)
  2. Accurately Use Scales to Measure Out All Ingredients
  3. Grind the Salt/Spice Cure to a Fine Powder
  4. Apply cure inside a Bowel
  5. Place Inside Bag and Remove Excess Air
  6. Place in Fridge for Curing

1. Calculate Equilibrium Cure or Brine

It always became quite a hassle to go through the calculations especially if I wanted to do 3 or 4 spice mixture variations for bacon projects at the same time. Quite often

(I have a large amount of meat after harvesting and animal and I have to do the calculations for the various meat curing projects.)

So I created this calculator and tool for easily doing the equilibrium curing and brining, you can find a link here to the calculator.

2. Accurately Use Precise Scales to Measure Out Ingredients

I really slow down when I do this part of it, since it’s really important, accuracy at this stage leads to good outcomes when it comes to your tasty bacon.

Because the measurements are sometimes like 0.5g for certain types of herbs and spices you might want to use. You really want to be precise about all these measurements.

3.Grind the Salt/Spice Cure to a Fine Powder

When I started out doing curing mixes, I used a good old fashion mortar & pestle to create a spice salt curing mix.

As I got older maybe lazier (or smarter) I wanted a more fine curing mix (without the arm work), I switched over to an automatic spice grinder.

These are not an expensive item but make a big difference in your curing mix.

Another tip I have is to do your salt grinding separately, first the salt, then separately grinding the herbs, spices and pink curing salt together.

And then combining the 2 for a final quick blitz in the spice grinder.

4. Apply Cure Inside a Bowel

Again it’s just about taking your time I reckon, having a good size mixing bowl is the way I like to do it.

And really wiping up the cure with the meat inside the bowl, so that the bowl is practically clean of curing mix at the end of it.

Another tip, it’s a good idea to do this reasonably quickly, it doesn’t take long before salt starts drawing a little bit of moisture out of the meat.

Then you end up leaving a small amount of dry curing converted into a kind of salt brine in your bowl. But as I said, if you move fast then you don’t get the moisture brine mixture left hanging around the bowl.

4. Place Inside bag and Remove Excess Air

Need some kind of air sealed bag, ‘ziploc’ work very well for this.

I like to kind of roll the meat up in the ziploc bag, with the seal slightly open on one end. This squeezes as much of the air out of the bag as possible.

Then you just have to ziploc close the last bit up.

5. Place in Fridge for Curing

When you place your pork belly cured bacon (or whatever cut of meat you are using for bacon) in the fridge. To get a little bit of a uniform shape, and forced the cure into the meat a bit more. I utilize the space underneath the fruit and vegetable containers in my fridge.

Quite often putting a little bit of extra weight with some cans of chickpeas or whatever. This pressing down on the cured meat, I presume just speeds up the process a little bit.

Some people like to wash the cure after, some people don’t, I think a very basic little wash is a good idea but I also like to leave some of the herb or garlic ingredients on the cured meat.

Example of the Calculations

1,000 grams of pork belly with 2.25% Total Salt

Percentage of Meat WeightAmount (Grams)
Sea Salt2.0%20.00 grams
Pink Curing Salt0.25%2.50 grams
Black Pepper0.50%5.00 grams
Dry Thyme0.50%5.00 grams
Juniper Berries0.20%2.00 grams

Process of Equilibrium Brining Bacon

  1. Calculate Equilibrium Brine
  2. Accurately Use Scales to Measure Out All Ingredients
  3. Grind the Salt/Spice Cure to a Fine Powder
  4. Dilute Cure Mix Completely in Water
  5. Place Meat into the Brine Cure Container
  6. Remove & Pat Dry

1. Calculate Equilibrium Brine (Calculator Tool)

If you skip straight to this part, I have mentioned that I got my mathematical brother to create an equilibrium curing and brining calculator tool, so if you want to have a look.

If I have a computer nearby, I just use a google sheet to keep a record of all the recipes & percentages, but I’ve been known to have a few too many pieces of paper floating around with “secret” bacon recipes.

2. Accurately Use Scales to Measure Out All Ingredients

Same as with equilibrium curing, having an accurate digital scale for this is a must. You really need a minimum of 1 decimal place, ideally 2 decimal places.

I have a few recommendations of decent digital scales, check them out here (near the bottom of the page).

3. Grind the Salt/Spice Cure to a Fine Powder

This makes it much easier for the cure to dilute in the water if you have finally ground cure mix.

As I said I like to do the salt separately get it to a fine powder, and then do the rest of the ingredients to a fine grind. After combing the two and give it a quick blitz in the grinder.

4. Dilute Cure Mix Completely in Water

I find lukewarm to cool water temperature work well, with a fine powder it dilutes pretty quickly, you just want to make sure you can’t see any particles of the cure. Once you’ve stirred and mixed it into the brine container.

5. Place Meat into Brine Cure Container

Isn’t much to say here, to submerge the meat make sure that the meat is totally underwater, at 40% water to the weight of the meat the should be submerged (some weight might need to to be placed on the meat to keep it submerged).

6. Remove Pat Dry

I just pat dry the pork belly or whatever meat your making into bacon. Some people like to wash the brine off, I guess it’s completely up to you and what salt level you decided to go for as well.

Examples of the Calculations

You add the water to the meat weight to give a total that you work out the percentages for:

1,000 grams of pork belly

2.25% target total salt level

Percentage of Meat + WaterAmount (Grams)
Water40.00%0.4 Litres
Sea Salt2.0% (0.02 x 1400)28.00 grams
Pink Curing Salt0.25% (0.0025 x 1400)3.50 grams
Black Pepper0.50% (0.005 x 1400)7.00 grams
Dry Thyme0.50% (0.005 x 1400)7.00 grams
Juniper Berries0.20% (0.002 x 1400)2.80 grams

Equilibrium Curing or Brining Smoking

  • Green Bacon (Drying – No Smoking)
  • Hot Smoke @ Low Temperature
  • Cold Smoke for 8-50 hours

I like often going after a pancetta style bacon, I end up drying out the meat in the DIY curing chamber or even putting it on a non-reactive rack in the fridge. Even though a normal kitchen fridge is running at 20 to 30% humidity, the pork belly that I am drying out is normally less than 1 inch thick it seems to dry out nicely in the kitchen fridge in between some light cold smoking sessions.

I’ve done a little bit of hot smoking bacon, but to be honest for me it’s not really bacon, as you’re just really curing and then low & slow smoking a piece of pork belly. So you end up cooking for the first time during the smoking session and then end up cooking it again when you decide to grill or panfried.

Cold smoking is the way I do most of my dry-cured bacon, I think the dry curing brings out the herbs and spices used in the mixture. I like to cold smoke normally over 15-20 hours, which gives it that subtle smoke angle that makes bacon awesome (pretty light smoke, high humidity and airflow of course).

Adding Sugar to Your Cure Mix or Not

I never go over about 1% sugar, but I realize some people like to make bacon candy or a sweeter type of bacon. And I can understand why sweetness does go very well with pork.

  1. Hi Tom

    How long would you cure or how long can/should you dry out bacon in the DIY meat chamber.
    I have made my own chamber and ive been curing bacon now for a while im wanting to dry it out as i understand you get more flavour and it can last longer.
    Ive not tryed my DIY chamber yet im just fine tuning the temperature and humidity at the moment.
    Thanks in advance for any information you could give me.

      Hey Craig,
      It depends on size and fat. It could be 2-4 weeks or much longer. The drying intensifies the flavor! So quality meat helps too.

      Awesome glad to hear you’ve got a setup! I kind of cold smoke in the evenings and stick the bacon slab in the curing chamber during the day the first 2-5 days. Then it has taken on a fair bit of smoke flavor. So on with the drying for a while. Since you are going to cook it you can choose the level of drying too. Sometimes I just get hungry and what to try it!
      Actually I just got a chunk of pork belly today! havent had a crack for a while. salute!
