Why is Oatly milk greenish in colour?

Hi Clarissa! 

No, a greenish colour is definitely not normal and we'd like to investigate this further.

Would you be able to reach out to info@oatly.com and attach a photo of the time stamp at the top of the carton, as well as let us know whereabouts you are based?

Thanks in advance! 

Love, 

Inez at Oatly 

I just had this happen so I shook it really well and it went back to normal so maybe that was the issue, it tastes fine now
