Have you ever bought a loaf, or a package of sliced Tillamook Cheddar and noticed a thin layer of white, crystal like formations on the outside? Before you cut it off or through away you cheese, read this! The white substance that you are seeing on your cheese is not mold, it is calcium lactate!

Calcium lactate is quite common in aged cheese because it forms during the natural aging process. When you see calcium lactate in cheese, it usually means you’ve found a well-aged and flavorful loaf. Well done, you!

The calcium lactate often looks like a white, film-like coating, or small dots. In older cheeses, like our Vintage Extra Sharp White Cheddar Cheese, it may even be sprinkled within the loaf. That’s what those little crunchy pieces are in your cheese!

Calcium lactate particles can be as large as peas, but they’re usually about pinhead-size, or a white coating when found in Tillamook Cheese, The most important thing to remember about Calcium lactate is that it is naturally occurring and perfectly safe to eat!

If you’re ever unsure or want to chat about what you’re seeing on your cheese, reach out to the Consumer Relations team here!

Funny. I sort of knew it was OK to eat, but still cut it off any away. I am kind of OCD about these things. Next time I will try and use my cheese w/out shaving off the white stuff.

My wife bit into a pea sized piece that was not crunchy it was solid and about broke her tooth. I am taking it back to Costco for a refund. She is afraid to eat any more of the wedge.

Hi Tom,

Ouch! I hope she is ok! The more aged a cheddar is, the more calcium lactate or "cheese crystals" will be in the cheddar. If you wouldn't mind contacting our Consumer Relations team (https://www.tillamook.com/contact.html) we'd love to get a little more information from you.

Thanks,

how can I prevent this stuff from accumilating

Hi Jan,

Thanks for your question. Calcium lactate forms naturally in cheese as it ages. The more aged the cheese is, the more calcium lactate will accumulate. If you dislike calcium lactate, we suggest choosing cheeses that are not aged. You can find all of our cheeses and how long they are aged on our Cheese Product Page.

Thanks again for reaching out!

Oh thank goodness. I have a mold allergy and a tight budget, so this block of Tillamook was a splurge. I'd seriously cry if I'd had to throw it away. Thank you so much for the peace of mind! And this was the top google result too so kudos to your web team.

Hi Jen,

I'm so glad this was useful for you! Moldy cheese is never fun, so we're glad it turned out to be calcium lacate:) I also shared your message with our web team and told them to keep up the good work. Thanks again for stopping by our blog!

All the best,

Thank you for this! I was about to throw out an entire package of the thin sliced cheese, and have actually scraped the calcium lactate off blocks before. From now on I'll just enjoy the crunch!

Hi tillamook,
I was very concerned until I read these messages, never eaten cheese with white, normally scrape off, but on thin slices that not easy; manager said i could return for a better one, but I may convince myself it's ok.

Hi Pam,

I hope this helps reassure you! Calcium lactate is completely normal and safe to consume. If you're ever concerned, feel free to contact our Consumer Relations team and send us a photo at info@tillamook.com. We're happy to double check with our Quality Assurance team just to be safe.

Thanks,

Is there calcium in medium white cheddar?
I am taking some meds and can't have any calcium for 2 hrs before or after taking the meds. But I love my cheese with my eggs.
Thanks

Hi Terry,

Yes, there are 180mg of calcium per serving in our Medium White Cheddar. You can find the nutritional information for this cheese on our website:

I’m on a constant search for soft cheeses, like cheddars, that have an abundance of calcium crystals. I have found only one brand of 15 month aged cheddar from England at a “natural foods” store and they cut and wrap it themselves and never seemed very engaged when I try to make inquiries or ask for suggestions. I’m no fromagier, formaggiaio, affineur and sadly, not even a cheesemonger. I will never be on the level of the greats like Monsieur Herve Mons(France), Rolf Beeler (Switz) and Luigi Guffanti (Italy) are examples of great European affineurs. I have been called a caseophile or turophile because I simply love every cheese I get my hands on. I tend enjoy the tyrosine crystals in the aged gouda and Parmigiano-Reggiano varieties but the calcium lactate are my favorite. I had no idea that Tillamook had cheese with crystals! My husband will be relieved because I am spending quite a bit of money on cheese when I make my weekly trip to the “natural store”. I can’t seem to spend less than $50-$60 a week on cheese that I know I love and I make myself buy odd cheese that I don’t think I would like but I want to have an open mind and open palate. I would love to hear any suggestions from your cheese experts. I have no problem giving you my direct phone line but I’m not sure how tp give you my information without plastering all over the internet. I’m looking forward to hearing back from someone on your staff because I know I have not even scraped a small scratch into the world of cheese that awaits me! Best regards!

Hi Ashley,

Wow! It sounds like you are a real cheese connoisseur! Typically our aged cheddars (3-5 year) are the most likely to have cheese crystals because they develop as the cheese ages. Unfortunately those are considered "specialty" cheeses and are not made as frequently, and thus can be difficult to find. If you are interested in our aged cheddars, you can call our Visitors Center at 503-815-1300 to place a phone order or check at your local Costco. For any other questions about our cheese, feel free to contact our Consumer Relations team at this link:

Sierra, thank you for responding so promptly and answering my questions and providing more information about Tillamook’s cheeses. You can rest assured that I will be calling and placing a phone order for some of the aged cheeses. I can’t wait to try them. Thanks again for the information and help!

Call me Impressed

Indeed, this came up as the top result as I sought confirmation that this block of Medium Cheddar before me was still suitable for eating after a time of non-refrigeration made tiny white spots very noticeable throughout the cheese.

I read all the way through the comments just because it was such a pleasant, informative thread. And that initial query by Ashley Warner was gold! Props to the Tillamook team for facilitating such great communication about the greatness that is Cheese.

Hi Call Me Impressed,

We're glad you enjoyed this post and the conversation that followed! Calcium lactate/cheese crystals can be confusing or alarming if you're seeing it for the first time, so we are thrilled that this article has been helpful to so many people. Enjoy your cheddar, and have a great weekend!

Best wishes,

The white pin size spots are not crunchy but mushy. They are only on the cut sides/edges. Since your site explains they are on well aged cheese, I believe this will turn into mold.

Hi Nan,

We're sorry to hear you're having trouble with our cheese! Feel free to contact our Consumer Relations team if you need any additional help or if this turns out to be mold: https://www.tillamook.com/contact.html

Any information you can provide from the package will be very helpful.

Are they also on your farmstyle cut medium cheddar cheese?

November 26th, 2017 at 9:37 am

Sierra

Hi Christy,

Typically cheese crystals/calcium lactate isn't as common in our shredded cheeses, or at least isn't as noticeable. However, we do use potato starch in our shredded cheeses to prevent the shreds from clumping together and becoming unusable. If you notice a white powder on your shredded cheese, it is likely a small amount of natural potato starch.

Thanks,

Sierra, of the Tillamook team
