Planning to make cocktails soon? Costco's vodka could be a welcome addition. Over the years, rumors have circulated about this popular liquor being a relabeled bottle of Grey Goose. However, Grey Goose has dispelled this myth, noting,"While both vodkas may use water from France's Cognac region, the origin of the wheat in the Kirkland brand is undisclosed."

Although Costco's vodka isn't the big-name brand, many people can't even tell the difference—and some shoppers use this to their advantage.

"On more than 1 occasion I refilled an empty Grey Goose bottle with Kirkland and served it at parties. Everyone thought they were drinking Grey Goose… everyone!" one Redditor wrote, calling the Kirkland Signature liquor "way more smooth than other vodkas."
