Museum workers in New Jersey broke through a Prohibition-era wall and a locked wooden cage to discover over 50 bottles and 42 demijohns of rare Madeira wine dating back as early as 1769.

Liberty Hall Museum at Kean University in Union, New Jersey, says the discovery yields the oldest known collection of Madeira in the United States.

“We had no idea the old bottles were there,” said John Kean, first cousin to New Jersey’s former governor and president of the museum. “We knew there would be wine, but had no idea as to the date. That was a major surprise.”

Historians and museum workers have been renovating Liberty Hall Museum, originally just called Liberty Hall, which was home to New Jersey’s first elected governor and signer of the Constitution, William Livingston.

The house was built in 1772, just prior to the American Revolution, and originally had 14 rooms. The estate changed ownership in 1811 to the Kean family and eventually became the 50-room mansion that stands today.

Its wine cellar was chosen to undergo examination and repair, but it was hidden behind a plywood and plaster wall built during the Prohibition.

“First we needed to get the wall down. We took the room apart and performed a complete analysis — paint analysis, mortar analysis, brick analysis to see what needed to be repaired and done to the room,” Bill Schroh, director of museum operations told CNN. “Lo and behold, we found this incredible collection of Madeira.”

The six-month renovation also led to discoveries of more wine in the attic, where demijohns of wine were found buried beneath piles of straw. Demijohns, or large glass vats, commonly held spirits in transit and for storage.
Bottles of Madeira created for the personal use of Robert Lenox, a millionaire and major wine importer from New York City, were among the bottles discovered in the renovation. Lenox died in 1839, according to the New York Historical Society.

“Nothing like this exists,” said president and founder of Rare Wine Co. Mannie Berk, referring to Lenox’s sealed, stamped bottles. “They could be worth up to $20,000.” Liberty Hall Museum would not say how much the total collection of wine could be worth.

If you found a cache of 18th century Bordeaux, you could forget about drinking it, it would undoubtedly be cooked or simply aged into vinegar. Madeira, though, is different. Madeira is the wine variety capable of surviving both heat and age. An 18th century Madeira has a pretty good chance of not only being drinkable, but excellent. We have a bottle of 1796 and a couple of 1863s still in our home collection. Karen finished the last of the 1815 years ago, alas!
