Perhaps their representatives will be more forthcoming? I get in my car and drive over to one of her neighbours - François Labet. He is the president of the Burgundy Wine Board, which represents this region's 3,500 winemakers.
"The US is the largest export market for the whole region. Definitely," he tells me. "They are the biggest in volume and the biggest in value."
And, until Donald Trump's re-election, the US market was booming. While French wines and spirits global exports fell 4% last year overall, sales of Burgundy wines to the US rose sharply.
In volume terms, there were up 16% from 2024, to 20.9 million bottles. This was worth €370m ($415m; £312m) in revenues, 26.2% higher than in 2023.
Mr Labet says the US accounted for about a quarter of Burgundy's wine exports last year.
Burgundy's reputation abroad is mainly for its red wines, which are made from the celebrated pinot noir grape. Indeed, in the English-speaking world, burgundy is not so much a wine as a colour.
The French word for the same colour is bordeaux; showing they know more about their wine, because while Bordeaux wines are mostly red, two-thirds of Burgundy is actually white.
These are predominantly made from the chardonnay grape. Chablis, one of the best-known examples, is extremely popular in the US.
Burgundy also produces an increasingly successful sparkling wine, called Crémant de Bourgogne, and a small amount of rosé.
All of which is good for Burgundy because while general red wine consumption just keeps going down, white is holding firm, and sparkling is going up.
Also, the reds that come out of Burgundy are, according to Mr Labet, the kind consumers increasingly want, as they are typically lighter than New World reds.
"What is interesting to see is that there is a strong de-consumption of what we call the big reds, made in the US. Wines with a lot of alcohol, aged in new wood."
Less sun and lower temperatures in Burgundy, even with climate change, means less sugar in the grapes and lower alcohol content.
