Think Twice Before Buying Your Baking Supplies At Costco

Despite being a great deal, the 25 pound bag of King Arthur brand flour may not be as great as it sounds. Flour can go bad despite the popular belief that it can last in your pantry untouched forever, and with 25 pounds of it, you'd better know what you plan on using it all for. One Reddit user took to the social platform to ask if this bag of flour is worth it, and the replies to this inquiry were interesting.

One Reddit user responded that when they did their research on Costco's bulk flour, they found a lot of people online saying it wasn't good quality flour and that there may be a reason why the flour is so cheap. Now, they also say they can't remember the brand name, only saying that it wasn't Kirkland (Costco's signature brand). This could mean that they're not talking about King Arthur flour and instead are discussing a different brand, but the hesitance remains. When buying bulk flour, you want to know what you're going to do with it before you buy it. Otherwise, it can go rancid or taste stale even before going rancid, per this Reddit commenter.

Other commenters were quick to remind the original inquirer that flour has a one-year shelf life, though Healthline cites an eight month shelf life, and even says it can go bad sooner than eight months. Ultimately, you want to check the expiration date on any flour you buy, whether at Costco or not, and you want to buy it in the right amounts. If you buy too much, you run the risk of it going bad before you use it all, and you may not know until you use and bite into a rancid baked good.
