Hello, The last several bottles of Diet Coke I have purchased over the past few months have been the 20 oz ("Recycle Me Again" in green writing on the inside of the label) and every single one of them has had a musty odor around the top of the bottle. After looking online I see there are several complaints about this issue and not much being said or done by Coke about it aside from a few people receiving coupons for more smelly bottles of coke. The most recent bottle has a date of SEP2021 and 2 codes stamped on the bottle: LLE165821 and LLE16441.
