Costco alcohol sales by state
Kansas is like Utah, and Pennsylvania and Maryland do not allow Costco to sell alcohol. Several additional states allow beer and wine sales but not hard liquor. There are no Costco stores in Maine or Rhode Island.
I'm not really that expert on Utah alcohol purchases. But Tony is right about going to liquor store for more high powered versions of stuff. I'm pretty easy and usually just buy regular ABV beers from random grocery stores. One local product that is kinda fun for a visit to Utah is Wasatch Brewing Polygamy Porter and it's pretty tasty. One afternoon a couple years ago a Utah buddy gave me a 22oz can of some sort of juicy IPA while we were hanging out on the slopeside Bypass Road at Snowbird. I think it was 8 ABV. One can of beer never hit me so hard/good
