Per the Costco-centric Instagram account @costcobuys, you can get six 32-ounce cartons of Kirkland Signature oat milk at just $8.49. While this sounds like a good deal, and some Costco shoppers claim to enjoy the oat milk, most have found the flavor of the Kirkland version to be too sweet.

Costco’s oat milk has 7 grams of added sugar per one cup, or 29% of the recommended daily sugar intake — meaning that every carton contains 28 grams of added sugar. This amount is in addition to the fact that oat milk naturally contains higher amounts of sugar than other dairy and non-dairy options.

Per dietitian Jorden Edinger, RDN, LD, "Oat milk can be enjoyed and included as part of a healthy, well-balanced diet [...] of colorful produce, healthy fats, and protein." Still, the market for oat milk has grown big enough that you can avoid overly sweet options like the ones offered at Costco.
