I have taken corked wine back to Costco and have received a full refund. Hope you do the same. Nothing worse then opening a bad bottle.
I picked up this same bottle today at our local Costco. The price and the barrel sample review seemed to be too good to be true. A 2019 is still pretty young for a CdP so I was going to let it sit in the cellar for awhile before I opened it. Based on your comment, I might open it early just to see if there is an issue.
