Costco Hard Seltzer Review

Many people consider the Kirkland Hard Seltzers to be nearly identical to White Claw, but I consider them closer to a substitute rather than a clone or copycat. 

I found the flavors to be solid, with my personal favorite flavor being the Black Cherry.


From what I read online, everyone seems to disagree about which flavors are good and which ones are misses, so I’m not going to go too in-depth on which I liked since it will probably be different for you. 

I thought the flavors were spot on with their name, and it was easy to distinguish the different flavors from one another. 

Most importantly, the hard seltzers are extremely easy to drink, and if you drink enough of the seltzers, you will feel it.

Who makes Kirkland Signature Hard Seltzer?

There’s no ambiguity about who makes the Kirkland Signature Hard Seltzer, and that is Patco Brands in Hood River, Oregon. Patco Brands makes other well-known hard seltzer brands, such as Mystic River and Texas Ranch Water.


The Mystic River brand and the Kirkland hard seltzer share the same flavors and nutritional profile, which leads me to believe that they may be the same drink.

 3.7/5 (3)

This review is only for the Mango flavor.
For me, the Mango was leagues ahead of the others in the box and its competitor's products.
The flavor was noticeably more 'full' than others of its kind.
Great taste at a terrific price
All of the flavors seemed to have an off taste. The flavor in each was barely there.
I wish I had purchased a smaller package.
