4 Things Every Expert Gets Wrong When Making Bone Broth

Apple Cider Vinegar in Bone Broth

I get questions all the time on how to make a simple yet delicious bone broth. After years of making it daily, I’ve learned what works and what doesn’t.

The worst part is that all the recipes and info you read online is mostly wrong. Blogs and news sites tend to post the same misinformation on how to make crappy bone broth or bone broth vinegar. 

I’m not sure where some of these mistakes started but I see most internet marketer food expert types peddle the same info on bone broth. It’s all wrong.

As a result I constantly get the same troubleshooting questions from friends and customers alike.

This article will go through the 4 things every supposed expert and website gets wrong about making bone broth. Ready? Let’s go!

Mistake #1: Adding Apple Cider Vinegar

Everyone and their mother thinks you should be adding apple cider vinegar or some type of acid to your bone broth.

Acid is typically added at the beginning with the water.  Perhaps these armchair quarterbacks even recommend letting the bones sit with the acid in cold water for 30-60 minutes before turning on the heat.

Read the definitive list of bone broth brands you can trust.

The thought is that acid helps draw out nutrients from the bones even before you start simmering the bone broth.  

What these charlatans and bloggers haven’t done is lab tested as much bone broth as I have. We send our bone broth for lab testing twice a year for vitamin and nutrient analysis, amino acid profiles and nutrition facts.

I suspect this is where some of the misconceptions around nutrient content in bone broth comes from. Similar uninformed bloggers peddle the notion that bone broth is rich in calcium. After all, it is made of bones, isn't it?

This is completely wrong. Look on the back of any bone broth and you’ll see at most 5% of your daily calcium per serving.

We’ve directly compared two batches of our bone broth for nutrients and vitamins. The first batch is made with apple cider vinegar, while the second without.

Calcium in bone broth with and without adding apple cider vinegar

Guess what? There was no significant difference in vitamin and mineral content. A few percentage points here and there with respect to iron, calcium and vitamin C.

It is important to put things in context in terms of nutritional benefits to you. While 10 mg vs 12 mg is a 20% increase, it amounts to nothing in your daily intake of calcium. 

Let me explain why. The recommended daily intake for calcium is 1000 mg.

10 mg serving represents 0.5% of your recommended daily intake.
12 mg serving represents 0.6%

If you want to save time and money in your homemade broth, I would argue it is a waste to use ACV to get an extra 0.1% of your daily intake. 

But if you still prefer using it, then go for it. 

Bone broth is not about the vitamins and minerals. It is about the gelatin, collagen, glucosamine and proteoglycans.

Next time you make bone broth, skip the apple cider vinegar. Your money is better spent elsewhere. If you do insist, you will end up with bone broth vinegar.

Mistake #2: All about the HEAT!

4 things experts get wrong about bone broth

How hot should you cook your bone broth? Lots of websites encourage you to look for the perfect low simmer with the occasional bubble surfacing every couple seconds.

This is a recipe for weak broth with no gelatin and thus no nutritional benefit.

You should think of making bone broth as harvesting collagen and gelatin from bones and connective tissue. You need heat to harvest collage and gelatin in an efficient manner.

A low simmer will still work, but your cook time will be significantly longer. Perhaps two days at a lower temperature. Why wait when you can have it done quicker?

We recommend cooking your bone broth as hot as you are comfortable with without the broth spilling over your pot. If you have a thermometer, I’d recommend 98 degrees celsius.

This is a hard rolling simmer with lots of bubbles popping up. Don’t be afraid of letting it boil from time to time as well. Especially if you are home and able to watch over it every hour or so. If you go out or go to sleep, better to turn down slightly to 95 or 96 celsius.

With this temperature, you can make a collagen rich chicken bone broth in 10-12 hours and beef bone broth in 16-18 hours.

If you’re using a crock pot or slow cooker, then heat on high with the lid on. On the stove it is better to keep the lid off. Since you can achieve a higher temperature, the lid is not needed.

Moreover leaving the lid off lets the broth reduce naturally which results in more gelatinous and concentrated bone broth. If you notice it reduces too much, you can always add more water to the level you started with.

If you just want to try one and not obsess over making the best one, then read my guide on where to buy bone broth

Mistake #3: Bones to Water Ratio

It takes a lot of bones to get that nice gel in your bone broth. This is where the big misconception around high prices for bone broth comes in.

Bones are expensive, and you need more than you’d think to make bone broth. This translates into why bone broth is not inexpensive these days, though we are working to change that.

So how many bones do you need for properly gelly bone broth? Think of your pot filled with bones as a cup filled with ice. You add water to the ice which fills in the nooks and crannies. The ice is the bones you’re using in this case.

For chicken bone broth we recommend 1.4:2 ratio of bones to water. If you have access the chicken feet to mix in with your chicken bones, then the ratio is closer to 1:2 bones to water (ex: 1 KG of bones per 2L of water).

For beef (or other ruminants) bone broth the ratio is closer to 1:2 bones to water, although this greatly depends on the type of beef bones you’re using.

Your mileage will vary depending on the bones you use, so best to experiment with a smaller batch before testing a larger one. There is nothing worse than finishing a lengthy simmer only to find you have average bone broth for your efforts.

Mistake #4: Poor Skimming Practises

Yes I’m calling you out for poor skimming practices. The first 1-2 hours of cooking bone broth is crucial as it sets the stage for the whole batch.

If you neglect skimming the fat, foam and impurities as they rise, you may end up with the dreaded cloudy broth.

This happens to the best of us. In our early days we had to pour out full batches of bone broth once or twice due to cloudy and murky broth. You know it when you see it. It looks like milk.

This is mainly due to not skimming properly, but also from stirring bone broth during the cook. Do not stir it, ever.

Take pride in skimming all the foamy bits every 20 minutes or so for the first 1 hour or however it takes to boil the broth for ten minutes or so. It is quite relaxing. After that you are good to go!

“Homemade broth, of course, is a whole food product. It’s a slow food, whole food, and real food that has been nourishing and healing people for tens of thousands of years.”

― Sally Fallon Morell, Nourishing Broth: An Old-Fashioned Remedy for the Modern World

Bottom Line

There you have it, 4 mistakes many people make when getting started making bone broth.

Hi Ami,

In my experience roasting the bones will not make a meaningful nutritional difference.

Connor at Bluebird Provisions September 12, 2023

Hello Connor! Thanks so much for this detailed and science backed article. I was wondering about roasting the bones beforehand – is it going to make any nutritional difference?

Ami September 12, 2023

Looks like I’ve been making at least 2 of the 4 mistakes. I buy 10# bags of chicken leg quarters (60# at a time) to can the meat for our fur babies. In my area the 10# bags go on sale for $.55-60 per # which is a real bargain as far as I’m concerned, you certainly cannot get 10# of beef or pork for $6 give or take!
I boil the chicken first then remove the meat from the bones then can the meat (saving the nice looking chunks to can separate for making chicken and dumplings for us. Then I put the bones back in the water with my vegetables (onion, celery and carrots) lots of herbs (sage, bay, oregano, thmye and spicy Basil) and vinegar (oops). I skim but not quite enough because even though I strain it 3-4 times using the finest mesh I can find it’s not cloudy but ends up with some solids floating at the top of the jars. After all that I fry the skins in the skimmed chicken fat for fur baby treats. I end up throwing away just the spent bones so I get as much out of the chicken as possible. I will definitely be leaving ou the vinegar and skim a lot longer. Thanks for all the great info!

Hi Amy, I’ve worked with a large company who was developing a Korean style bone broth that sold in restaurants in Korea.

I did a deep dive into the techniques and I am a fan. The milky texture has a lot of flavor (although it looks less appetizing to most North Americans).

I would go for it!


Connor at Bluebird Provisions July 25, 2023

What do you think of the Korean way to make bone broth? They boil the bones (I’m referencing beef tail and leg) for about 10 to 20 minutes, dump out the water wash the bones and pot and then refill and boil the heck out of it to get the milky white broth for soups. Although I disagree with them about scooping out and adding more water. I just boil the bones to honey comb and add water when the level gets low. Please check some Korean videos and respond? Like Maangchi.com or Kimchimari, or others.

Amy July 25, 2023

After the broth cools to room temp, I place a large bowl on top with a good amount of ice, make sure the bowl touches at least one inch of the broth. Have 2 more bowls handy. One to switch with the ice while you scrape the congeles fat into the 3rd bowl. Now store in containers.It worked perfectly for me. Enjoy.

Lupe July 15, 2023

Hi Martin,

Yes you are right about the lid and water reduction. Reducing it (with lid off) will usually yield a stronger broth. But you can simply drink more of a weaker broth to get the same effect.

I would keep doing what you are doing!


Connor at Bluebird Provisions July 08, 2023

Hi Connor, thank you for a very informative article!

I have a question regarding water to bone ratio and reducing. I make bone broth in my stockpot on the stove, and I put enough water in to just cover the bones. I don’t want to remove the lid. First of all because of the smell, and second of all I don’t want to reduce the bone broth while the bones are still in it, as I want them covered with water.

So the question is wether I should reduce the liquid after removing the bones. Am I right in assuming that the total amount of gelatin is the same in the weaker unreduced broth as in reduced broth? If so, can’t I just drink more of it and get the same benefits even if it doesn’t turn to gel when cooled?

Martin July 08, 2023

Hi, thank you for posting this informative article! I’ve always wondered about the apple cider vinegar. I’ve even heard of adding a tablespoon of baking soda at the beginning of the simmer stage.
I’ve been making my bone broths for years even before broth became a raving health trend. My mother always started her soups with a rich bone stock, she never had any health problems and gave all the credit to her soup! Making scratch bone broth is time consuming so I will purchase some of these broth packs from BBP as they will definitely come in handy.
I recently used oxtail bones. The finished broth/stock rendered a rich, mouthy flavor, unlike any other beef bones I’ve used.
An extra step may have been a contributing factor for the flavor- I gave the oxtails a sea salt rub then browned them in the oven for a short time. This also seemed to eliminate the need for constant skimming.

Hi Cristi,

you can make delicious bone broth in a pressure cooker. Checkout this recipe: https://bluebirdprovisions.co/blogs/news/instant-pot-bone-broth-recipe

Connor at Bluebird Provisions May 26, 2023

Ok guys firstly I am Jewish and for those who makes there broth a good time is right before Shabbat starts and let it cook on level LOW in the crock pot I guess it could be HIGH to draw out the collagen. I added celery carrots onions rosemary and garlic. Three packs of chicken bones KOSHER at 2.50 each . And filled the water level 2" to 3" above the whole thing. Ok the result was a weak watery broth. Next time I will less water as suggested. But the next day I read an article that you should blend the remainder of the mix bones and vegetables and the broth and place in those soup jars. So I reheated the mix and WOW what a difference. Not sure exactly if it’s safe to drink I will find out later today ie toilet run ;). Cheers

Sf May 26, 2023

I’m new to making bone broth. My brother uses his instant pot (cook at high pressure for 3 hours). Since it is in a pressure cooker, I did not do any skimming. Will pressure cooking like this produce a good bone broth? Thanks!

Cristi May 26, 2023

Thanksgiving time: My mother always took the roaster with gravy and dressing scraps and dumped all the bones and carcass into it. She added onions and celery. added water to almost cover bones and let it simmer all night. after cooling the next day we used a big slotted scoop to remove big stuff. Big pieces meat were saved for the soup. We then used a strainer to remove small bits of bone and other solids. She would Pour it into quart jars, leaving head room, and freeze. scraps of meat were added to the jars also.. We continue the tradition. Experimenting I have found I can make a tasty broth by saving the bones from roasted or grilled chicken and when I have enough i boil it as with the turkey. Have a pot of beef scraps and bone simmering now. Not so easy to get beef with bone.

Pat Childs May 26, 2023

Hi Luke, I am not familiar with insulted cooking. How much heat is there in this method?

Regarding pressure cookers, they work great. You can see my recipe here: https://bluebirdprovisions.co/blogs/news/instant-pot-bone-broth-recipe

Connor at Bluebird Provisions February 17, 2023

Hi Christine,

There is nothing wrong with cloudy broth from a taste or nutrient perspective. In Korea and Japan, they exclusively prefer cloudy broths. I would drink it!

As fort he collage without the gel, it just means you have less protein and collagen per cup of broth.

If yours does not gel at all, you most likely have 2-5 g of collagen protein per cup. With a little bit of gel closer to 5-7 g. And a full gel you will have 8+ grams per cup.

hope this helps.

Connor at Bluebird Provisions February 17, 2023

Hi, thanks for the write-up

I am 38 and just following shoulder surgery – turns out I got a lot of osteoarthritis going on in there too! – I’ve been looking into sources of collagen type 2 to slow down the need for a new shoulder.

So I’m planning to make chicken bone broth. I can get cheap bones, but it seems to be very energy-intensive cooking.

I was wondering about your view of insulated cooking ie, heat and boil for 30 mins then leave in a heavily insulated container for 24 hours…. then maybe repeat.

If I was to try insulated cooking how would I test to see if I am indeed harvesting the collagen?

Also how quickly would it be possible to achieve the same results as you with a pressure cooker on the stove top set to high?

Any help would be greatly appreciated



Luke February 17, 2023

Thanks for the article, Connor!
I had a couple of questions please.
I’ve read all over that I shouldn’t want cloudy broth – from a health-only perspective (taste doesn’t bother me) is cloudy ‘bad’ or still fine to drink?

Secondly, everyone keeps saying it should turn to gel. If too much water is added this won’t happen but will the collagen still be extracted the same either way? I don’t want to eat gel, mine tastes and looks like soup – am I still getting collagen at the same level, albeit not as concentrated?
Thanks :)

Christine February 17, 2023

To the bluebirdprovisions.co administrator, Your posts are always well-referenced and credible.

Freya Caro February 15, 2023

Hi Myrtle,

Yes this is how I do it when i make it at home as well. The bonus of the fat cap that forms as it cools is preservation.

It will keep longer in the fridge if you do not remove the fat cap.

Connor at Bluebird Provisions January 27, 2023

Hi Kathleen, yes you can absolutely use it!

Connor at Bluebird Provisions January 26, 2023

Hi Lisa,

In your case you do not need to roast them a second time.

Connor at Bluebird Provisions January 26, 2023

After simmering my bone broth for 24 hours in a slow cooker, I refrigerate it overnight and remove the layer of fat that forms on the surface. The beef fat is very solid and easily lifted off. The chicken fat is a little softer but still easily removed. There’s always a lot of fat. Does anyone else do this?

Myrtle Balderson January 27, 2023


u mention ACV not impacting the calcium etc, but what about the protein and gelatin levels in the broth! that is the whole point of the broth.

So does it affect?


dan January 26, 2023

Can you use a prosciutto bone for bone broth?

Kathleen Mooney January 26, 2023

I often make bone broth using chicken carcasses and drumsticks. My question: if the chicken and drumsticks have been roasted with the meat on to consume for a meal, do I need to roast them again after the meat is removed? I’m assuming the blanching and roasting directions apply to raw bones.

Great taste and texture. Will be purchasing this again. Works great on its own for sipping and also in soup!"
