What Is Wine Balloon?

Eric Corti created a wine gadget called the Wine Balloon, now known as The Wine Cork, which helps preserve wine bottles for those who cannot finish a bottle in one evening. To create the device, Corti used a blood pressure pump and tubing, which enabled him to create a new way to “cork” wine by using high pressure to prevent exposure to air [1].

He attached a balloon to the blood pressure tubing and inserted the device inside the wine bottle. By filling the balloon with air, Corti was able to remove excess oxygen from the bottle, providing an airtight seal that preserved the wine.

What Is Wine Balloon?

He and his wife tested the device on a few bottles of wine and confirmed that the new “wine balloon cork” effectively kept the wine fresh for an extended period, allowing them to finish the bottle. As a result, they began their new business venture.

To use The Wine Balloon, one must lower the deflated balloon into the wine bottle until it reaches the wine. Then, by squeezing the pump, the balloon inflates until it makes contact with the inside of the wine bottle, creating an airtight seal with about an inch and a half of contact between the balloon and the bottle. After months of testing his prototype, which received positive feedback from testers, Corti continued to research and improve every aspect of his invention (via Air Cork) [2].

To expand his business further, Corti sought the assistance of investors by appearing on the popular show Shark Tank.

About the Founders Of Wine Balloon

Eric Corti was frustrated with having to throw away half-drunk bottles of wine due to the lack of proper methods for preserving open wine at the time. To address this problem, Corti used his ingenuity and combined a small balloon with the tube and pump of a blood pressure cuff, resulting in his own product called The Wine Balloon, according to Just Wine [3].

Corti and his wife enjoy a glass of wine now and then, but like many wine drinkers, they struggle to finish an entire bottle in one sitting. They grew frustrated with wasting expensive bottles of wine that lost their freshness once opened, prompting Eric to seek a solution to their problem.

After some contemplation, Corti devised a method to preserve the freshness of opened wine. He disassembled a blood pressure cuff, attached a balloon to it, and inserted the new device into the wine bottle. Inflating the balloon created an airtight seal, removing excess oxygen from the bottle. After his wife confirmed that the wine stayed fresh long enough for her to finish the bottle, the couple decided to invest in Eric’s idea and launch a new business venture.

Despite making a few sales independently, the Cortis recognized that they needed assistance to establish the Wine Balloon’s success. They brought their product to Shark Tank, hoping to strike a deal with one of the Sharks to secure financial backing and marketing connections for their business.

The Pitch Of Wine Balloon At Shark Tank

The Pitch Of Wine Balloon At Shark Tank

Eric Corti appeared on Shark Tank to seek $40k in exchange for a 30% stake in his business. During his pitch, Corti emphasized that people often avoid indulging in a glass of wine or two with dinner because they are unable to preserve the rest of the bottle once it’s been opened. The existing wine preservers on the market do not do their job properly, according to Corti, which is why he invented the Wine Balloon.

Corti demonstrated how the product works by inserting the balloon into an opened bottle of wine and pumping air into it until it touches the inside walls of the bottle, creating an airtight seal. He then tilted the wine bottle upside down, showing that only a small air bubble remained in contact with the wine. The Wine Balloon can preserve wine for about 3 to 4 days after being opened and is composed of medical-grade latex, which does not change the taste of the wine [4].

Robert Herjavec tested out the product while Kevin O’Leary asked about the balloon’s material and production cost. Corti revealed that the Wine Balloon has been selling on a small scale for six months and has sold 700 units at a retail price of $22, with a production cost of $6.50 per unit. O’Leary offered Corti $40k, but only if he agreed to sell the product to the #1 wine preserver company and collect a royalty on it.

Lori Greiner made a counteroffer, proposing to buy out Corti for $500k. Corti has invested nearly $65k into the product and is patent-pending, with hopes of the patent being accepted soon.

Eric Corti appeared uncertain about the proposal made by Lori Greiner, but Mark Cuban joined forces with her, offering $600k for full ownership of the business. Cuban put pressure on Corti to accept the deal immediately, but he requested a 3% royalty in addition to the $600k. Kevin O’Leary praised his foresight but Cuban and Greiner refused his request, leading Cuban to withdraw his offer.

With Cuban out of the picture, Greiner reverted to her original offer, but then Cuban returned with a new proposal for $400k. Daymond John and Robert Herjavec decided not to invest, leaving Corti with two offers to consider. Under the pressure, Corti eventually caved and accepted the $400k offer from Cuban and Greiner in exchange for full ownership of his business.

Wine Balloon After The Shark Tank

After Eric backed out of the $400K royalty deal with Greiner and Cuban, he decided to market his product on his own, and it turned out to be a wise decision. The product gained attention on Food Network’s The Kitchen Inventors, where Patrick Raymond and Steve Greenberg traveled across the Midwest in search of innovative kitchen gadgets.
