The wife told me she "heard" that Kirkland vodka is really good. So we drove to the Costco not so near us that sells liquor and obtained same. It's $18 for a 1.5 L, Grey Goose is well into the $40s, $45 I think. So, I break it out last night, shake it with ice and pour it for us, and she thought it was in fact quite good, and she won't touch anything but GG. I like GG but find Tito's is good, I'd rate Kirkland better than Tito's, and it's cheaper, here.
It's very smooth, no evidence for cogeners I could detect, a hint of a fruity taste, clean finish.
I also got some Kirkland Tennessee bourbon and Scotch to try one of these days.
Kirkland now has box chardonnay as well, 3 L for $13, it's "OK", quaffable but not transcendent. Their California cab in a box is amazing. They also have Kirkland Sonoma chardonnay in bottles for $13 and it is quite good at that price, nice balance.
I love Costco, own some stock, which has done well.
