I spent a couple of months in Switzerland for a project and supermarkets there often have this booth that me and my friends referred to as the "Kingdom of Cheese".

The Kingdom of Cheese is a climate-controlled enclave with just cheese - the person there is happy to help you decide because they know you'll be back eventually as indeed the products there have those crystals.

Old aged gouda is the best cheese I ever laid on my tongue. We live in Switzerland next to French border, so there is no end to universe of fine aged original Gruyeres, Beaufort or even Cheddar (but that one probably worse than what one can get in UK), plus all AOC Italian ones. Simply hard cheeses with grain, there are hundreds to choose from.

I love them all, but that gouda taste is something else to me and my wife. French shops just around the border luckily import some of it, I never saw it in Switzerland shops.

One way to upmark any cheese for us to put ie black truffles or wild black garlic in it.

Talking about gouda, gotta get me some slices before kids munch it all again.

People in the Netherlands are usually not at all proud of their cuisine, but the cheese is definitely a nice aspect (as someone who eats the >1 year ripened stuff almost daily)

Although for me some of the French cheeses are the best. Just what you're used to I guess :D

How long until cheese makers start adding the crunchy crystals to give the appearance of quality without the actual quality?

This happens already, at least it does in the UK. Most cheaper brands of “extra mature” supermarket cheddar have added crystals. I don’t actually mind that much - I do think it is a genuinely slightly more enjoyable product with the crystals.

There are also fake ways of accelerating aging to create this effect, like the Old Amsterdam cheeses you’ll find in the Netherlands. That particular brand has a lot of fake qualities to it that creates these effects.

Is this something they disclose on the packaging? I'm curious how to identify this in the cheese I buy.

Aside from cheddar (or similar), the crystals are always inside the cheese, so the appearance is nearly the same as those without the crystals.

If you're ever in Pullman, Washington, stop in at the WSU dairy store and get a few cans of Cougar Gold cheddar. Cheese in a can sounds weird, but it's delicious, made by the students, and it ages really well -- I've got some cans in my fridge which are coming up on a decade old now. It's kind of a waste to use an aged can for mac and cheese, but I used part of a younger can for mac & cheese and it came out beautifully.

Whenever I keep mild or medium cheddar too long it goes "mature" before long, but it doesn't taste good. French cheese, on the other hand, matures (affines) quite nicely at home.

Cheese crystals are umami. Many of them are glutamate crystals. I am curious if the other amino crystals have a similar flavor profile.

jsbg 2 days ago

In the sense that they contribute to umami taste, yes. But most commonly the nucleotides inosinate (from meat and fish) and guanylate (from dried mushrooms) are the other molecules that provide umami flavors.

facile3232 2 days ago

Also MSG, obviously.

sophacles 2 days ago

rbrownmh 2 days ago

The umami flavor of cheese, especially hard cheeses, is incredibly under appreciated. And I'll never understand the popularity of pre-shredded cheese...

dekhn 2 days ago

Umami is a lot more present that people recognize. I've built up an intuition for this over the years, and also sort of trained my tongue.

What we call umami is a subjective experience that has an underlying molecular cause, but it's complicated: more than one molecule contributes to the sensation, different foods have different molecules, many people can't recognize it on its own, etc.

The most easily recognized umami tastes seem to come from hydrolyzed soy protein and yeast extracts- both are added to tons of food. The canonical example is Doritos, which are a masterpiece of modern food industrial optimization. Doritos are mostly corn, but they also add whey (cheese derived umami), MSG (molecular, isolated glutamate in salt form), buttermilk (multiple flavors including umami), romano cheese (more umami!), tomato powder (umami), inositate (umami). It's basically an umami bomb.

From what I can tell, the best umami flavors come from a combination of several different molecules combined with some salt. the combination seems to potentiate the flavor significantly. You can also saturate out your receptors- if you drink a highly concentrated broth, you'll see there's some upper limit to the amount of umami you can taste and after that, additional aminos are just wasted.

coldpie 2 days ago

For firm & hard cheeses, the bad molds very rarely penetrate the surface. If you get some questionable looking mold on the outer surface, you can cut off the outer couple of mm and enjoy the remainder just fine. For rustic/home made cheeses, handling the "bad" mold on the outer surface is a normal part of the aging process before it makes it to the customer anyway. https://cheesemaking.com/blogs/learn/how-to-bandaging-chedda...

Also, if you get bright white(!) spots on cheese like Brie (which is made with white fungus), it's usually just the cheese "reactivating". You - theoretically - don't even need to cut off anything.

GuB-42 2 days ago

I remember having a brie-like cheese cut in half and left forgotten in the fridge for more than a month. The mold had reformed completely, as if it they were made like this in the first place.

It tasted fine, no one got sick. Kind of underwhelming to be honest, but it wasn't particularly tasty to begin with: industrial cheese, pasteurized milk. It fact, that it still had some life in it surprised me.

No, that is most likely mold. Not all white spots are positive, especially if they are on old cheese in the fridge (as per the article).

stevenwoo 2 days ago

It does give a method of testing at home at the end, though, with hard being crystal and soft being mold.

GuB-42 2 days ago

Even if it is mold, just remove it off the surface. It doesn't penetrate far on hard cheeses like Gouda.

Also the reason why I don't buy pre-grated cheese, it doesn't age well. It also tends to be lower quality to begin with.

talkingtab 2 days ago

It seems wrong to me that most of what people now call cheese is not at all like what I think of as "real cheese". I have ended up making cheese and it is both fascinating, productive and tasty. While there are many "recipes" for cheeses, they are mainly focused on preparing the cheese for aging. These are often techniques, like washing the curd (gouda) or cheddaring (cheddar).

The aging part takes more work. I converted a 7.5 CU refrigerator using an Inkbird temp controller. That works surprisingly well. Currently I'm attempting to improve the humidity control with a humidity version of the Inkbird.

But highly recommended. I have everything I made (even the failures) with the exception of one of the first attempts.

anamexis 2 days ago

What do you think of as "real cheese"?

talkingtab 2 days ago

In Europe, and at gourmet cheese stores, you get a slice from a wheel. It is alive, in the sense that it has not been "treated" to increase shelf life. A wheel of cheese is like a little biome or green house or garden in a bottle. The rind of the cheese is the wall. It allows the cheese to breathe, but in a way that preserves the life inside it. Once the wheel is cut, the bottle is broken, and while the cheese can be kept for a time, it will start to degrade. The humidity (~80-85 %) is important so the cheese does not dry out and it does not become a nice home for unwanted mold, bacteria and fungus. The temp of ~55 F is also important so that the little things can live but don't start over growing.

If it comes from a wheel where it was aged, almost any cheese is good - depending on your particular taste. The aged ones with crystals are great, especially Dutch ones, but "local" cheese is almost always wonderful.

I was in Colby, Wisconsin a couple of times and I found the local Colby cheese to be good. Many locally made cheese are good, but again if they are bagged in plastic then they do not compare with the "real" thing.

There's a whole concept of "farmer's cheese"- quickly prepared from pressing whey, minimal preservation- intended for nearly immediate consumption. Cottage cheese, queso fresco, paneer, ricotta, are all examples... then of course you have brined cheeses... feta, etc...

These "most" people might be country specific.

I make cheese myself (both fresh and year-long aged ones) and virtually all the people I met knew what real cheese was.

If it is the "ultra-processed" cheese what you are referring to, that might not be liked by some but that's still cheese, regardless of its plastic-y feel.

Not sure at all what you’re referring to. Surely it’s not “american cheese”, which has been the punchline of obvious cheese jokes for decades. Or the powder in mac & cheese boxes, which is its own thing.

From where I stand, I see grocery stores in the USA stocking large varieties of cheddars, fontina, gouda… all “real cheese.”

globular-toast a day ago

In the USA the main problem is everything has to be pasteurised which rules out many "real" cheeses like camembert.

Tangential, but I recently noticed that natamycin, an antifungal agent, is being used in packages of shredded cheese as a preservative.

I was a little taken aback on seeing it, given that antibiotic stewardship has been pushed so much in the last decade.

I realize that natamycin is an antifungal and not an antibiotic, and that mechanisms of developing resistance are likely different between eukaryotes and prokaryotes. However, I’m still somewhat concerned what long-term low-level exposure will mean.

0_____0 2 days ago

Tangent on tangent - in addition to the antifungal there is also anticaking agent (nothing crazy, often some type of flour) that noticeably changes the mouthfeel of cheeses that come pre-shredded. If you notice a grainy texture in your food, try grating it off a brick instead!

kadoban 2 days ago

Yeah, especially for things like cheese sauces I find that it's better to just grate it yourself. It will _not_ melt correctly otherwise, and the additives mess with sauces more than you'd think.

I stopped buying pre-shredded cheese a decade ago. Block cheese is cheaper, lasts longer, and cooks better. Pre-shredded is just worse in every way aside from convenience. Using a cheap rotary grater like they have in restaurants makes this almost a non-issue.

Is this a promotion for the National Cheese Stockpile?[1] The US has about 1.5 billion pounds of cheese in storage in a cave in Missouri. Really. There's a USDA welfare program for dairy farmers, and they have to put the excess milk somewhere. So it's made into cheese and stored.

Antifungal resistance is actually a thing. Fungi can evolve or acquire resistance mechanisms against antifungals, just like bacteria and antibiotics.

Arguably it's an even bigger problem than antibiotic resistance: fungi are eukaryotes, just like us, and in practice this means we have less chemical weapons to fight them with. Losing the relatively small arsenal we have would be quite bothersome to say the least.
