Hey Everett!
Thanks for reaching out, and welcome to the forum!
I’m sorry that your bars are tasting different! We did make a change to the bars recently, but it was purely resizing: we increased the length (by around 1cm) and therefore weight of the bar from 51g to 55g. There were no changes to the actual recipe, however.
If you could reach out to support@huel.com with the batch details on your bars (pictured here), so our technical team can look into it, that would be great! They’ll also be happy to help you out with a return or exchange, if you need!
