Perfectly preserved centuries-old cherries unearthed at George Washington house

America’s first president George Washington never did cut down the cherry tree, despite the famous story to the contrary, but he did pack away quite a few bottles of the fruit at his Mount Vernon home.

Dozens of bottles of cherries and berries — preserved in storage pits uncovered from the cellar of his mansion on the banks of the Potomac River — were discovered during an archaeological dig connected to a restoration project.

Jason Boroughs, Mount Vernon’s principal archaeologist, said the discovery of so much perfectly preserved food from more than 250 years ago is unprecedented.

“Finding what is essentially fresh fruit, 250 years later, is pretty spectacular,” Mr Boroughs said. “All the stars sort of have to align in the right manner for that to happen.”

Whole pieces of fruit, recognisable as cherries, were found in some of the bottles. Other bottles held what appear to be gooseberries or currants, though testing is under way to confirm that.

Mount Vernon is partnering with the US Department of Agriculture, which is conducting DNA testing on the fruit. They are also examining more than 50 cherry pits recovered from the bottles to see if any of them can be planted.

Records at Mount Vernon show that George and Martha Washington were fond of cherries, at least when mixed with brandy. Martha Washington’s recipe for a “cherry bounce” cocktail survives, and Washington wrote that he took a canteen of cherry bounce with him on a trip across the Alleghenies in 1784.

These cherries, though, were most likely bottled to be eaten simply as cherries, Mr Boroughs said.

The quality of the preservation reflect a high calibre of work. Slaves ran the plantation’s kitchen. The kitchen was overseen by an enslaved woman named Doll, who came to Mount Vernon in 1758 with Martha Washington, according to the estate.

“The enslaved folks who were taking care of the trees, picking the fruit, working in the kitchen, those would have been the folks that probably would have overseen and done this process,” Mr Boroughs said.

“It’s a highly skilled process. Otherwise they just wouldn’t have survived this way.”

The bottles were found only because Mount Vernon is doing a 40 million-dollar revitalisation project of the mansion that they expect to be completed by the nation’s 250th birthday in 2026.

“When we do archaeology, it’s destructive,” Mr Boroughs said. “So unless we have a reason to disturb those resources, we tend not to.”

“In this case, because of these needed structural repairs to the mansion, the ground was going to be disturbed. So we looked there first,” he continued. “We didn’t expect to find all this.”

They know the bottles predate 1775 because that is when an expansion of the mansion led to the area being covered over with a brick floor.

Mount Vernon announced in April, at the start of its archaeological work, that it had found two bottles. As the dig continued, the number increased to 35 in six distinct storage pits.

Six of the bottles were broken, with the other 29 intact. Twelve held cherries, 16 held the other berries believed to be currants and gooseberries, and one larger bottle held both cherries and other berries.

Mr Boroughs believes they have now uncovered all the cherries and berries that survived.

“There is a lot of information that we’re excited to get from these bottles,” he said.
