It may not be quite as fickle as avocados, but picking up a loaf of bread from the store can involve a complicated decision-making process to ensure its freshness. After all, there’s nothing worse than bringing home a product that’s only a few short days away from expiring and becoming inedible. But similar to other time-sensitive products, a few tricks can ensure your sourdough or whole wheat doesn’t go bad before you have a chance to finish it. Most store-bought bread has a shelf-life of about seven days or about three or four if it’s homemade, according to Healthline. But keeping the bread in a warm, moist environment can speed up the rate at which it turns moldy. By storing your loaves in the refrigerator, you can lengthen the shelf-life of bread by three to five days. And if you’re saving your slices for an extra special occasion, you can also keep fresh bread in the freezer for as long as six months before eating. It’s not uncommon to check expiration dates and examine produce while filling your cart at the grocery store. But when it comes to bread, there may be one major piece of information about its freshness you could be overlooking. The plastic ties and tags used to keep bread secure in their bags actually use a color-coded system to keep track of the date on which it was baked and packaged, according to EatingWell.

Besides being the one odd item you always seem to find when cleaning up the kitchen, the color of the tag on a loaf of bread can help you figure out how fresh the product is and when it was stocked, EatingWell reports. The simple code breaks down to blue for Monday, green for Tuesday, red for Thursday, white for Friday, and yellow for Saturday. And Wednesday and Sunday deliveries aren’t missing for no reason: Most bread makers exclude them from their production schedules.ae0fcc31ae342fd3a1346ebb1f342fcb If this system seems too tricky to remember, just remember the alphabetization trick behind it. Blue-tagged Monday bread is first in the cycle, followed by green-tagged Tuesday loaves, which continue down the rest of the week. This would mean that your best options for fresh bread on a Tuesday would have blue or green plastic ties. And what about the date that’s sometimes stamped on the tag? That actually corresponds to the loaf’s sell-by date and not when it was baked, according to budgeting website Wise Bread. While it may not give you as much information on how long it’s been on the shelf, it can still be helpful if a particular brand or store only uses a single color or branded tag.

Of course, this helpful system may not always be a foolproof way to tell how fresh your prospective bread purchase may be. The color coding is ultimately in place for store employees who use it to help restock and remove bread that’s past its prime, meaning you may likely never see more than one or two tags on the shelf at a time, according to Snopes. In some cases, different producers could use another color-coding system entirely. If you find yourself confused by what you see in the store, consider calling the company behind your favorite brand or asking your local supermarket’s staff what colors they use to denote each day of the week.
