People are just now realizing that Ocean Spray’s cranberry sauce labels are flipped on their head — and it’s all about the “bubble.”

CRANBERRY sauce is a key part of the annual Thanksgiving dinner — but the labels leave people stumped.

Eagle-eyed shoppers have noticed that the Ocean Spray labels are flipped on jellied cranberry sauce.

That means the rounded edge typically found at the bottom of most canned foods is on top of Ocean Spray’s cranberry sauce cans.

According to Ocean Spray, this is actually by design and intended to keep the jelly intact, a spokesman said CNN.

In fact, it creates an air pocket on the rounded side (top) so customers can “swipe a knife across the rim of the can to break the vacuum and the stem easily slips out.”

The method is also not new and has been used since the early 2000s.

It comes as confused customers have noticed the flipped labels over the past few days.

One user tweeted today, “I’ve always wondered why Ocean Spray’s cranberry sauce labels are upside down.”

Meanwhile, another asked: “I always thought it was weird that the cans were upside down.

“Anybody know why @OceanSprayInc has been doing this for the longest with cans of #cranberry sauce?”

While a third tweeted in July, “Can anyone tell me why the Ocean Spray cranberry sauce label is always upside down?”

According to Ocean Spray, 400 million pounds of cranberries are consumed by Americans every year.

Of this, 20 percent is consumed on Thanksgiving alone.

Walmart and Target sell 14-ounce cans of Ocean Spray’s jellied cranberry sauce for $1.76 and $2.19, respectively.

To save money, you can purchase a same-sized can from Target’s Market Pantry brand for $1.49.

The revelation comes as shoppers face higher expenses this Thanksgiving, with prices up as much as 69% year-over-year.

To help, many retailers have launched special offers in the run-up to the holidays.

For example, Kroger offers a $50 meal for 10 people.

While Lidl has unveiled a $30 Thanksgiving basket, it claims it will be enough to feed 10 people.

Even department stores like Target and Walmart took part in the campaign.

Additionally, Aldi will sell Thanksgiving staples at 2019 levels.
