The Coca-Cola Companycoke zero 20 oz bottle

N Jun 05, 2019 Review updated:

Bought bottle of Coke Zero tonight and opened took a drink and noticed the bottle top smelled like mold or mildew. Smelled the cap and the inside of cap also smelled the same.. poured soda out into a cup and didn't smell bad tasted a bit weird. It is one of the new bottles . I would place bets that I drink more Coke Zero than most people in America and can tell when it's off. I dumped the remainder of the bottle before thinking it could have helped if I saved it. My apologies. Have there been any other complaints? Thanks for listening. Code stamped on the bottle is AUG1219 LPC1949 if that helps

    Hey all!
    I experience this every time I’ve had a soda made by Coca-Cola for the past few months.
    Did some research and found that the Coca-Cola Company has recently changed how the bottles are made. They now use 100% recycled plastic. It seems that the smell is common with recycled plastics. I hope they find a way to hide it!!

    Here’s a link to the article on the bottle change.

    @Teri Beau I have also received a coke today, I simply searched google for “soda bottle smells musty” no brand, nothing, and this thread comes up. I’m disgusted. This is just awful.

    I'm in Birmingham, Alabama and the last 2 bottles of Diet Coke I just got from the grocery store also smell like mold and mildew! I thought it was my fridge; then I thought it was just the outside of the bottle, but I've wiped down the newest bottle with a Lysol wipe, and it IS the contents that smell! I'm pouring it out! I'm upset that I didn't realize where the smell was coming from when I drank from the first bottle. :(

    I'd sure hate to give up drinking Diet Coke, but this not acceptable!

    Same my wife bought one earlier today 100 miles from home and I bought one on my way home. Both were mildew smelling caps and top inside. My wife thinks it's the new bottles they're using. The smaller ones in six packs we buy haven't had this issue.

    I've had this happen a number of times now and not with diet or zero products. Regular coke and regular Sprite the smell is exactly what everyone here is describing. I didn't know what to think and I've saved my last bottle, the Sprite for days now and keep checking it to see if it goes away...nope still smells like hell. The only thing I've thought that I haven't seen here yet is that maybe it could have something to do with the fact that all blessed bottles are recycled plastic. Maybe that has nothing to do with it and it could be some type of chemical or spray to prevent covid cuz I thought other things too the only thing is that it's inside the bottle it wouldn't be a spray that goes inside the bottle. Any way..I'll be placing a call. Thanks to everyone here who commented their ideas...

    I drink a LOT of caffeine free Diet Coke and almost every 16.9 oz bottle I drink lately smells either like caulk or old cat pee. What the heck is going on? It’s so gross I keep dumping them out and wasting a ton of money. Don’t know if this is safe to drink. Shouldn’t have to smell the bottle before drinking it. If this doesn’t get resolved soon, I’ll be switching to CF Diet Pepsi. So nasty!

    Every bottle of the last two six packs of 16.9 oz bottles of Coke Zero (with the new red label) I've bought have had a burnt plastic smell inside the bottle. The coke tastes normal and doesn't smell abnormal when poured into a cup, but it's definitely strange and a bit alarming.

    YES!!! I opened one last night while working and was like omg this smells like an old sponge that needs to be thrown away. I opened another one today, same. This is unreal!!! I still have it. I'm keeping it. This could be dangerous. Some kind of moldy machine or ingridents.

    Coke, you're gonna have a huge law suit on your hands if we all get sick. I'm a diabetic and I drink Coke Zero products. All of them. Including the Coffee Cokes that rarely are even on the shelf!!!

    Bought a 20oz bottle yesterday at a local variety store. When I opened it, the smell of mildew was overwhelming. Upon closer inspection, the entire bottle has a faint greenish haze. I dumped it. I can't imagine how the whole bottle smells that bad, particularly because the outside of it doesn't smell at all. It's just when the bottle is open that it stinks. Gross.

    I smell BO as well. I first noticed it on a Barq's Diet Cream Soda I got from a gas station a few months ago. Im having a Coke Zero from the vending machine at work today and it smells the same - ARMPITS. I usually bring a 12 pack of diet or zero coke to work and I dont think its the product, is the bottle!!!

    I have noticed the last 4-6 two liters of Coke Zero have smelled like old musty water. As soon as I twist the lid open the smell hits me in the face. The lids smell especially bad. I have been wanting to decrease the amount of Coke Zero I consume, this is definitely helping me accomplish that goal.

    So, I’ve been noticing this with the last several six packs of Coca Cola that I’ve purchased. To where I won’t drink them. First, they want to explode - even if they have been sitting still for a long while, then after I prevent the exploding the mouth and lid of the bottle smells like burnt plastic.

    Not the first time I’ve had troubles with exploding coke for no apparent reason - had every single bottle of 5 six bottles to the same thing. But, the smell is very new to me.

    I've been smelling Cumin in my Coke Zero bottle! I thought it was from when I ate Mexican food because I've frequently had it lately. Then, today I didn't have any and I smelled it! It's the cap I think. I even got two others to smell it and they did, too. Sometimes I smell it and sometimes I don't. Must be the plant.

    I just called the Coca-Cola Consumer Affairs line at 1-800-GET-COKE to report a smelly bottle, but they didn't have an answer, so I did my own research and here's the best explanation I've found: it might be the build-up of phenylalanine.

    https://listverse.com/2018/03/21/top-10-fascinating-diseases-that-you-can-smell/

    If you’ve ever drunk a bottle of diet soda and noticed the warning that it contains phenylalanine, you may have wondered about the purpose of that warning. Phenylketonuria (PKU) is another inherited disorder where patients are unable to break down the amino acid phenylalanine. People with this disorder must be careful to avoid foods containing phenylalanine, such as those that contain the artificial sweetener aspartame, like diet soda. If left untreated, PKU can lead to intellectual disability, seizures, and behavioral problems. Many countries actually have newborn screens for this disorder, allowing parents to start treatment early on. AN INTERESTING SIDE EFFECT FROM THE BUILDUP OF PHENYLALANINE IS A MUSTY ODOR THAT MANY DESCRIBE AS BEING "MOUSE-LIKE.”[5] The disease was actually first described in 1934, thanks to this odor. A mother of two intellectually impaired children approached Dr. Asbjorn Folling, complaining of a strange odor being emitted from her kids. Urine samples were taken and studied, leading to the description of the disease.

    I purchase a Diet Coke (in a 20oz plastic bottle) at my local Dunkin yesterday and it had the smell of an old rag. I thought at first it was the bottle but I finally smelled inside the top and it seemed to be coming from inside the bottle. I drank about 1/4 of it before smelling inside, now my tummy hurts. Ugh.

    I just bought a Coke Zero today at Sam's club and it had an horrible rotten smell and the top of the bottle was also darker in color. Then I went to another Sam's club same day and bought another coke zero and when i opened it, same thing. This happened to me the day before with one I got at Arco and since then I have had a migraine. Anyone else also getting migraine? I sill be contacting coke cola company on Tuesday.

    I just thought I’d chime in here as well… I just opened a new 2 liter bottle and I smelled terrible mildew smell. I was in the middle of doing stuff around the kitchen and I thought I had an old dish rag laying somewhere. The smell was so strong it was even left on my hands. I washed my hands and still notice the smell. When I sat down to drink my Diet Coke it had a weird chemical taste to it and I got a severe headache and didn’t feel well. I went back to smell the Diet Coke 2 liter bottle and it was awful. So strong I had a hard time even getting the smell off my hands. I’m going to contact coke as well. I’m from Georgia so you think it would be pretty fresh coming to me.

    @Shannen Manso This happened to me as well. I did contact Coke and they sent me a coupon for a new one. Sadly, I just got a new one and the same issue. It seems to be with the bottles that have been recycled and not broken down before being made into something else.
    I asked them to tell me how they sterilize their bottles during the recycle process, but they did not answer. If they are using a detergent like Dawn, that might be it as that product often smells of mildew, but apparently is not.
    It is all disturbing.

    @Shannen Manso it seems to me all the sodas bottle I've bought have smelled like this recently. I noticed it with Diet Pepsi first, then Mountain Dew, and then Dr. Pepper. I noticed all the bottles have expirations of August or September of 2021 and I think they are bottles that were produced for last summer and sat in the warehouse during covid shut downs. Now they are cleaning out all of last summers inventory from the warehouse.

    I have noticed this “body oder/smelly armpit” smell when I’ve opened a number of Diet Coke bottles, and once the smell was REALLY BAD with a Diet Dr Pepper bottle. Last night I got yet another Diet Coke, but this time I wiped off the inside and outside of the bottle neck with a wet, clean wash towel, dried it, and the smell was gone, prompting me to think it’s some kind of chemical. Since this has happened multiple times and I’ve seen now to multiple people, I am going to call a consumer reporter at a local T.V. station, since it looks like Coca-Cola isn’t answering questions from individual consumers. I urge others affected to do the same, since this “smell” may be evidence of harmful chemicals. LET’S BE SURE OF WHAT WE ARE BUYING AND HOW IT COULD BE AFFECTING OUR BODIES, CONSUMERS!

I’m crazy addicted & drink ... a lot ... of the stuff. Been drinking it for 40 years. I even had a job as a demonstrator pushing “the Great New Taste of Coke!” In the 80s! lol

    I just found this googling musty Coke Zero. I have the same issue in the last two 6 packs of bottles I bought from Walmart. It’s almost like an after taste or smell. I have been feeling weird and wondering if it’s from this. Also wondering if they are spraying them with some type of disinfectant for covid. Anyway it’s gross! Reminds me of dirty dish towel smell.

    I just googled “musty smelling Coke Zero” because this is the second bottle I’ve opened that smelled like a dirty dish rag! It’s definitely inside the cap. I plan on calling Coke and asking what’s up. I’ll report back what they say.
