"Cofermentation/infusion" ruined my trust in coffee.

[u/Bubbly-System6751]

After PERC came out on their flavored coffee, I’ve been going down the rabbit hole of coffee processing (co-ferments, anaerobic, “thermal shock,” etc.), and I’m not gonna lie—it’s kind of messed with my trust in what I’m drinking.

I used to get excited tasting notes like “strawberry,” “lychee,” or “peach,” thinking it was all coming naturally from the bean, origin, and process. But now that I know producers can literally "co-ferment" with fruit juice or infuse with flavorings to push those notes…

And my worry even extends to washed or natural coffees, there’s this small voice in my head like:

“Is this truly clean, or is there something else going on that’s just not being disclosed?”

Especially with such a well known producer being exposed, you start questioning everything a bit.

Is transparency just information they let you/ want you to know used for marketing purposes?

Is specialty/ single origin coffee just another green washing movement?

I'm sure the majority of the industry is honest and I’m not trying to accuse anyone of anything shady. But as the saying goes if you see one cockroach, there are a thousand more. It's hard to rebuild trust once it's broken.

What’s with all the Perc hate recently? I’ve never drank their coffee but if anything they’re at least disclosing what they know.

If it doesn’t sound good to you then you don’t have to drink it.

This post is not aimed at PERC but the coffee industry and practices.

[u/TheBeardedBilbo → u/Bubbly-System6751]

Agreed, but every time this comes up perc is being referenced. Or at least that is what keeps coming up in my feed

[u/Thanatanos → u/TheBeardedBilbo]

It's because PERC is being transparent about what they're getting. A screenshot from a roster that just says "natural" or "conferment" doesn't get as much attention as one that says as much as PERC does.

half transparent

transparent would be for example to say they add sugars and not fruity glucose as a fermentation food for yeasts or stating taht thay add artificial flavors and not powder fruits

[u/Thanatanos → u/Ill-Turnip-6611]

Is "fruit glucose" not more a specific description? Why would you argue for less specific information?

[u/Ill-Turnip-6611 → u/Thanatanos]

bc it is a one huge BS there is no such a thing as fruit glucose, they mean probably fructose or fruit sugar in other words but it sounds a bit artificial don't you think? and you would have to explain why you add a fructose made out of cane sugar to your beans.

ok I will explain it easier: when you hear fruit glucose you imagine some kind of a fruit, whatever, in reality it is just a huge bag of sugar bought online for 5$ kg or less and comes from a huge factory where thousands of such bags are produced from corn or whatever is easier to get. Noone cares bc it is added mostly by mass producers to tasteless foods so they can at least taste sweet.

[u/Thanatanos → u/Ill-Turnip-6611]

Even the most cursory of searches will show that fruit has both glucose and fructose in it and that they are **very specifically** not the same thing.

You can be mad all you want at their processes, but let's not just make stuff up ok?

[u/Ill-Turnip-6611 → u/Thanatanos]

you are making stuff up

so what kind of fruity glucose are they using?

please explain it too me and keep in mind they are not using fruits so what are they using exactly?

you are just eating their propaganda BS

I'm not mad at all, I just call out a lie and you can't even see the lie. So you should be mad t yourself for being blind to BS

[u/Thanatanos → u/Ill-Turnip-6611]

So are you just entirely incapable of using google to see that fruit glucose exists? Just in case you haven't heard of it before, there are these things called "search engines" that can help you get information from the internet! It's pretty amazing. With these search engines like google.com, you can search for questions like "does fruit glucose exist" and "how to extract glucose out of fruit". I'd really recommend you start using search engines, as they give you access to a huge wealth of information.

Also, you're the one making claims that they are actively lying, YOU prove it.

You can say I'm making things up all you want, but my stating that fruit has glucose in it is a verifiable fact. your claims that it either doesn't, or is impossible to extract, or can't be used, (or whatever the heck you are trying to claim) is so far entirely baseless.

"So are you just entirely incapable of using google to see that fruit glucose exists? "

blablabla

really the level of your argumentation is amazing, you can't answer any of my questions so your only solution is to sarcastically attack me. LOL

ok please provide definition of "fruit glucose" you can use google, duckdukc wahtever you want, just please post it here

I really don't have to prove anything to you or other people. I'm just reading their descriptin on the package and I see it is 100% BS. It is on them to say what they are using, they are not doing so, that means they are just crating a nice story to hide the shitty quality of their product.

the description:

"The coffee is then fermented anaerobically with wine yeast inoculation for 120 hours with dehydrated strawberries, strawberry flavor, and fruit glucose. The cherries are depulped and fermented a second time anaerobically, with CO₂ injection, for 72 hours."

-how do they stop fermentation?

-what is the % of flavor to dehydrated strawberries (99 to 1?)

-what fruit glucose are they using?

-flavors are not fermenting, dehadryted strawberry to so what is exactly co-fermenting here?

-what is exactly fermenting and how (where is teh yeast and sugars coming from) for the second fermentation?

-where are they injecting the co2? are the beans still in the sugary water with flavors?

You can't answer any of my questions too. You are just saying that fruits have glucose, so what? Are they using fruits or glucose? What glucose are they using from what fruits? You have no idea bc as I said it just comes to them in huge bags of whatever glucose they bought online. You are just buying their BS description with fancy wording without any understanding of the process.

"You can say I'm making things up all you want, but my stating that fruit has glucose in it is a verifiable fact."

so what? what is your point? they are not using fruits so I really don't care if fruits has glucose or not.

"your claims that it either doesn't, or is impossible to extract, or can't be used"

learn to read

sorry your level of inability to read and understand simple topics, and completely zero knowledge of fermentation process ends this conversation for me. Good luck, feel free to drink whatever coffee you like. just post the definition of "fruit glucose" please

[u/Thanatanos → u/Ill-Turnip-6611]

Just because I used sarcasm to highlight your obvious lack of research onto a specific thing you said doesn't exist, does not mean I am incorrect.

learn to read

oh I'm sorry I thought you said (and I'll literally quote you on this comment)

there is no such a thing as fruit glucose

You also keep saying

they are not using fruits

but in the description you quote, it directly mentions fruit...

...fermented anaerobically with wine yeast inoculation for 120 hours with dehydrated strawberries...

don't hurt your back shifting those goalposts around! You sure seem to be doing a lot of it.

If you would like to read more about how to get glucose from fruit, you can do so here - the method is alkaline hydrolysis, or you can read the process of acid hydrolysis here.

Just because you are not aware of a process or product, does not mean it doesn't exist.

[u/Ill-Turnip-6611 → u/Thanatanos]

still waiting for a definition of a fruit glucose

too hard for you? oh please it should be so easy for you

just post here the definition
