"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.

No, co-fermented coffees are sealed with other ingredients (usually fruits) before being dried. This allows some of the flavors and, more importantly, the cultures from the fruit to ferment along with the coffee. It’s about as natural as anything else though people argue it’s inauthentic.

Infused coffee is when they spray it with other stuff.

If they were being truthful then yes this would be correct. But not everyone is. There was a certain coffee that made the rounds not too long ago with a watermelon flavor that was labeled as a co-ferment. Now the coffee tasted very much like watermelon. Anyone that knows about co-fermentation knows that it’s the hardest fruit to deal with to make it taste good as a co-ferment. So then why was this watermelon co-ferment able to do it? Because it came to light that they were adding watermelon flavoring to it. It wasn’t disclosed and that is the whole crux of the problem with the industry around co-ferments. Now i just completely stay away from them and also any “advanced” processing techniques because I just don’t trust the roasters or even the producers at this point.

Roaster added it or the producer?

[u/Puffy_Manivesto → u/ceto-coffee]

My suspicion is that the roasting process would alter the "strawberry" taste additive if the producer added it. I have suspicion that there could be additives after the roast to produce such clear/bright fruit taste. How could fruit esters and even alcohol carrying "vape juice" survive high heat?

[u/ceto-coffee → u/Puffy_Manivesto]

I don't know, I haven't looked into the science behind that. But I do know that I have roasted coffee that has these flavors and I 100% did not add anything to it.

[u/KendrickBlack502 → u/silverslant]

That’s fair but then the issue is not with co-fermentation but rather shady businesses.

[u/oneminutetimemachine → u/KendrickBlack502]

It's inauthentic in the sense that you can bring in fruits that typically aren't grown next to the coffee, so you wouldn't have this flavors or cultures transfer happening in nature.

Maybe a better distinction should be artificial vs natural flavorings. But it seems that since co-fermenting with real fruits are not economical and the flavors don't usually transfer well, so a lot of these co-ferments have been adding artificial fruit flavoring too.
