Hi Morten André!
That is indeed not something to get excited about, our apologies. It may be a piece of the aroma we use that did not mix correctly. It seems you did not check in with our customer care team for this and we would like to sort this out with you of course and follow up internally on it as well.
For that reason, we invite you to contact us through the Live Chat on the website or love@jimmyjoy.com to make this right with you.
Thanks in advance!
“It's a standard vanilla protein shake taste, but less sugary which I appreciate. I add this flavor to the strawberry or wild berry flavors to make a more milkshake-y taste and texture, along with some soy milk.”
