For the nitty-gritty details, take a look:
The three white teas they tried were a classic "Silver Needle" from the Silver Needle Tea Company; a "Nepal White" from Royal Tea New York, which had an unusual aroma for a white tea, namely muscatel; and "Midnight White" from In Pursuit of Tea—I could not find this tea on the company's website, so do not know exactly what it was. The cheeses came from The French Cheese Board in New York City.
You may remember that from a chemistry point of view (as I blogged on 7/1/16), most white teas are almost indistinguishable from lightly to moderately oxidized oolongs.* Both kinds of tea are rich and complex in flavor, and the chemicals in them tend to activate the cool and especially the warm receptors.
The cheese that paired well with all three white teas was a Beaufort.** This fascinating cheese originates in the Haute-Savoie of France, up in the Alps. I fell in love with this cheese as a young girl when I spent a summer there with my family.

Milk for this cheese comes from two breeds of cow: 80% comes from Tarentaise and 20% from Abondance cows. These cows are well adapted to high altitudes, rough terrain, and Alpine vegetation. The vegetation they consume is critical for the flavor of the cheese: plant terpenes pass unchanged into the milk and then into the cheese.

Tarentaise cows come from the Tarente valley in Haute-Savoie, where their cheese has been made for at least 2000 years—Pliny the Younger talks about it! Abondance cows were bred by medieval monks for their cheese in the same area. These monks cleared trees from the mountainsides to allow the growth of lush pasturages filled with forage plants rich in terpenes.
|This graph, from Chion et al***, shows the plant families present in Alpine hay forage (Meadow) and in Alpine Pasture. The Poaceae are poor in terpenes, while plants from the other families are rich in these chemicals.|
These terpenes give Alpine cheeses a distinctive citrus/floral/piney quality not found in lowland cheeses. In fact cheeses made with milk from these same cows during the winter, when they are fed hay are (literally) a pale simulacrum of the summer cheese because hay, even hay from plants rich in these volatile terpenes when fresh, has lost them.****
There are two secrets to why white teas and Beaufort pair well.
Here's the first: while the terpenes in Alpine cheeses such as Beaufort may not be exactly the same as those in white teas, they activate the same array of cool and warm receptors. For example, both cheese and tea have limonene, which, as its name suggests, has a lemon flavor, and activates cool receptors. By contrast, the terpene β-ocimene is in Alpine cheeses but not (to the best of my knowledge) in white tea. It has a warm, sweetly floral aroma, that complements the aromas of a number of compounds in white teas.
Here's the other secret: Beaufort has a very high fat content—by regulation at least 45%. How does this help the pairing? Fat turns off the hot receptor TRPV1, and allows chemicals that activate the warm and cool receptors to be appreciated. The flavor of white teas is characteristically described as "delicate." I think that perhaps the better word might be "faint"—in fact the trio had to increase the proportion of tea to brew water to bring out the teas' flavor. Turning off TRPV1 allows these faint flavors to come to the fore. As Sara notes: "[Beaufort] not only brought out the softness of the [Silver Needle] tea, but it brought out a bit of floral aroma as well."
==>> By the way, am working on a sequel featuring white tea to my book "Three Basic Teas & How to Enjoy Them" (available at Amazon). In this sequel you will find out why white tea is more like oolong than, say, green tea, even though the processing steps for oolong and white tea are so very different.
