Impressive as the Kirkland vodka is, however, the best thing about it might be its price – assuming you already have the Costco membership, you can get a 1.75 L handle of it for $27, less than a single 750 mL fifth of Goose costs. Kirkland, on the other hand, is far more distinctive: a slightly more noticeable burn and notes of charcoal and olive that might lend themselves well to a martini.

As previously noted, Goose just sort of fades off into a very mild burn with no real standout flavors. Nearly identical on the nose and tongue (slightly vanilla-y, slightly sweet, very smooth) it’s not until the finish where the two really differentiate themselves. The rumor’s foundation is certainly easy enough to see. And in the Bartender’s opinion, the Kirkland Signature is superior. So, are they the same thing? Drumroll, please… Additionally, the Bartender cites her above-average depth of experience with vodka-tasting, as well as her lukewarm reaction to Goose from the fancy frosted bottle, as qualifications to make the call. While taste tests are always going to be somewhat subjective, it seems likely that comparing two products for objective similarities and differences should be far easier to do with accuracy than simply trying a single spirit and giving it a rating.

The most likely theory the Bartender found was that KS had bought an old Grey Goose distillery and was using water from the same river in France to produce it, but again, it was presented without any evidence. Google was no help, as there were no substantiated claims either way, just a lot of arguing back and forth. There’s just no possible way to write a decently comprehensive piece about Kirkland Signature’s bowling-pin-sized vodka offering without addressing the rumor that swirls around it – is it repackaged Grey Goose? Every Costco representative I’ve talked to about the stuff has at least mentioned the rumor, as have many of the people who have seen one of the bottles near my liquor shelf (usually it’s too tall to go with the rest and demands special display).
