Tasting Table writer and Certified Sommelier Hayley Hamilton Cogill put together a list of the best Kirkland wines found at Costco, and the top pick is one you can find in a 3-liter bag (the equivalent of four bottles) inside of a box for as little as $12.99. It should be no surprise that one of the best-value Kirkland wines comes in a box. What should come as a shock, on the other hand, is that Hamilton Cogill actually called the 2022 Kirkland Signature California Pinot Grigio a "straightforward" and "refreshing option for enjoying while entertaining a crowd." Not bad for wine from a box, huh?

As for the specificities of how this wine sips, Hamilton Cogill so eloquently described it as boasting "a nice balance of zesty, fresh acidity and ripe fruitiness, with a smooth, soft palate and low 11% alcohol." Adding on to the description, Hamilton Cogill also distinguished "flavors of ripe melon, fresh citrus, yellow peaches, and green apple." Even better, this wine stays fresh for up to six weeks after you open it, giving you plenty of time to make a dent in those 20-something glasses it serves.

Should you grow tired of drinking this wine in those weeks, Hamilton Cogill also suggested using it to make a large batch of white wine sangria. With its tart and fruity palette, Kirkland California Pinot Grigio could be one of the best white wines for sangria. Plus, it doesn't hurt that it's so inexpensive.
