What's the white FLUFF on my coffee (not mold!)? Coffee under the microscope

[@9faris3]

Man. I almost discarded my half full jar or coffee thinking it was molded. Thanks to my science education background, I'm quite a curious person and now I stumbled across this. Thank God and thank you for making this.

[@hiteshjain5484]

Are you still drinking it and does it taste okay? I have just tossed 2 diff jars as they seemed mouldy exactly like this.. I am sad as I definitely wasted money, but was too paranoid to let it be. Still wondering if I did the right thing. 😢

[@9faris3]

@@hiteshjain5484 Hello. Sorry for the late reply. Yes I still drink my coffee from that supposed "moulded" coffee. Taste still the same and I've never fell sick from drinking it. I also threw in silica packet (the thing that absorbs moisture) and guess what? Those white crystals that we thought was mold, had actually gone! Hahaha so yeah. It's actually just crystal that appears like mold

[@H786...]

@@9faris3 just curious are you supposed to put silica packets in food.

[@tblackproductions2888]

Glad to hear!!! You might address the fact that a google search reveals hundreds of results claiming that is IS mold.

[@cindybesitos8933]

My instant coffee had little fluff now I now what it is, it expires in one month therefore I want to make sure don’t want to discard it🫡

[@dongentelman7858]

I just have seen this white stuff in my Nescafé Gold coffe jar, and was very suspicious about this, where did it came and was about to throw all my coffe, but thought to make a little research about it and then here i am watching the answer I am looking for, thank you ..going to make my instant ☕ right now.

[@animeloverotaku8685]

same...just found this on my nescafe gold. havent taking coffee for 2 month and now i see this. then google led me here. is drinking this coffee safe?

Same. But it's only in my nescafe gold, my other jar of coffee doesn't get these crystals..

[@thatsdaniellelol]

This might be my favorite channel!! I SO Love exploring the microscopic worlds around us!! You’re so awesome. Thank You for this!

[@nigelmagoo]

These may be caffeine crystals, but an old opened jar I had contained a much finer, soft, threadlike matrix that completely bound the particles into a slightly elastic mass. Under magnification, it didn't look anything like these crystals, and the contents smelled very sour and off. I wish I still had my microscopes so I could have taken an image.

[@lovi90696]

Thanks man... Same thing happened with my nescafe gold....my wife already threw half bottle.. Then I thought of doing some research and I found you... & you saved my half bottle of coffeee cheers

[@rainascarlette]

Thank you so much man! I was about to discard my full coffee jar after reading some blogs/forum saying that these all white strings are mold or pest webs. And thankfully I'm not convinced with what they said and stumble upon your video right after the forum 😂 Thanks so much!!!!

[@SKZ0325-LEEKNOWWEKNOW]

This happened to my coffee last year and it was like 2-3 jars of nescafe gold and now it happened again cause I was out of town and I need to do some research cause it is a waste to throw them. Glad I came to this video. You saved me months and months of coffee. Thank you ver much!

[@vivl4862]

I have observed the same in my newly opened Moccona instant coffee. I put it away as I was afraid of drinking it. So, is it safe to consume it ?

[@saulemaroussault6343]

It is !

[@stephaniel7669]

This is so helpful! I just sent a complaint to my favourite coffee company accusing them of mold (eek) and they told me it’s crystals. And I didn’t believe them (cos it looked fluffy). Then I landed on this, and you are a LIFESAVER hahaha I was getting very yucked out.

[@urshllakaul6191]

Thank you so much. I was worried it was fungus and i threw away 3-4 spoons of coffee also bcoz of that 😅 And then I thought let me find out 1st and found your video here..

[@plastictouch6796]

Google is so bad nowadays if you try to figure out if it is mold or coffee crystals this is the only answer that makes sense and you have to find it by going into a reddit post first. Based on your video the only way to tell is by putting it under a microscope. Unfortunately the little field microscope i have doesnt have nearly enough power to see cells. Could really use a way to tell on visual inspection with the naked eye. This video almost makes me sure they are coffee crystals in my case. But would really have appreciated more b-role and camera work on the crystals within the coffee at a visual or close up level to compare. And then maybe a comparison to what aftual mold on coffee looks like.

[@BrendaCoyle]

🌟🌟🌟 Another excellent video... thank you so much. I don't drink instant coffee myself, it's disgusting (I prefer going to my local café for my caffeine shots) but I always keep a jar of instant in the cupboard for cooking (walnut and coffee cake etc) I have thrown away and have had to replace so many jars in the past, after seeing white bits in my coffee...who would have known what these strange white things were, if it wasn't for you! Fascinating videos...🌟 I love your inquisitive enthusiasm 🌟

[@MrBeefyweefs]

Thank you so much! This is amazing, and is the only thing I could easily find that answered my question satisfactorily. I was pretty concerned about my coffee fluff... bless

[@isaiahperez1115]

Your explanation and investigation was spot on!

[@jsmead]

Superb video -- a great look at using the scientific process to get an answer -- I plan to use this as an example for my middle grades Biology students! Thanks!

[@HappyJoya98]

you just saved another jar of coffee😂😂😂

[@mkc0321]

i saw this fluff in the Nescafe Gold coffee, thanks for the detailed video, but the big question remains, is it safe to consume with this fluffy thing or should I trash it ?

[@nyern]

Depends if you consider caffeine safe to consume I guess

[@Nas911]

Wow! Thank you for this info. I saw this in my coffee AFTER making a cup and having a sip. It didn’t taste good and checked the coffee, saw this white stuff I tot I might’ve ingested some mold. Now I feel better. Your info is very helpful 👍🏼

[@Bodomi]

Thank you very much for this video! I opened a military ration pack and the freeze-dried coffee included looked exactly like your coffee and I got a bit concerned that the coffee had somehow gotten moldy, which in this case would indicate a production error, Googled a bit and found your video, I'm quite relieved to find out it is of no concern. First time experiencing this from rations. What do you think the cause might be? Only thing I can think of is that these rations have been stored in a 39.2F degree environment over an extended period of time and that has caused it, or could it be the opposite, that they've been in a very warm environment? What do you think?

[@sreyamiriam]

So it's not an issue, can be consumed?

[@Bodomi]

@@sreyamiriam Did you watch the video? He explains how it is oxidized caffeine.

[@jeremycrochtiere6317]

Look into focus stacking your microscope images or videos, it'll give you clearer images and prevent the constant autofocus. Just a suggestion. Great video This white stuff does looks a lot like hyphae from a fungus. So can't blame ya for checking what level magnification are you using here?

[@sentinel9490]

Hi Oliver! I have tested the 2x dslr adpter with the iris diaphragm (NDPL - 1(2x)). It works for me but it is far from perfect. The iris is pointless in it, i had the same results as you. As for the glare... I didn't experience such problem. The optics in it are good enough but the whole system takes down the resolution and it corrupts the effect of my plan objectives. For me it worked better with my stereomicroscope. The overall quality of the adapter is pretty good but could not beat a lensless adapter by any means. It worked for me well, but the cheaper peace of metal, lensless adapter is much better. The only problem with it is that my fototube is too long for it on my compound microscope and it is not parfocal. I could solve this problem by screwing out the fototube and placing the lensless adapter in its hole. My DSLR (I also have a Canon 600D) takes much better images with the lensless. I have a chinascope (Levenhuk 500T which is similar as the swift 380T, but it is built with halogen). Conclusion: It works and prafocal, so convinient. It decreases the resolution and the picture on the sides of your field of view are pretty blurry. Personally I would go for the lensless option.

[@harveyacosta2352]

Seems that instant coffee is a mixture of things that looks and tastes like coffee but is not really coffee.....

[@shotgunkawaii116]

If it is a crystal then its bad for drinking it?

i found it in my new instant coffee this morning, at first, i tbought it's spider web...

[@YoungGandalf2325]

Very cool video. I would think instant coffee would not have enough moisture for anything to grow in it. The caffeine crystals must mean that you have the good coffee! You should buy some decaf instant coffee to use as a negative control.

Hi, I know this is a bit off topic, so I understand, if you don't want to answer that. I would like to order slides with samples on and I am not sure which ones are worthwhile. Do you have any recommendations for samples to order (I don't care which manufacturer or website)? Thanks for your videos, they helped me a lot in my first steps of microscopy :D I'm from Germany, just for records.

[@Microbehunter]

Get cross-sections from plants because they look pretty. Animal tissues often do not look as regular, patterns are not so nice. You can buy slide boxes with mixed slides from Amazon, but if you want to go for quality then try to get them from the Company LIEDER (a German company). They are expensive, however. Here is the catalog: www.lieder.de/files/de/K32D-SER-ww.pdf

[@nicoackermann2249]

@@Microbehunter Thank you very much for your reply! I will look into that 😁

Depends on what you want to learn about. You should combine looking at your prepared slides with reading about the structures you are seeing.
