The Story BEHIND WROTHAM PINOT
The wine it took an army and 2000 years to create.
In the 1950s, an unusual wild grapevine was noticed growing against
a stone wall in the village of Wrotham in Kent, southeastern England.
Its age was estimated at 200 years and its origin was shrouded in mystery.
The
grapevine leaves were distinctly gray-green and each had an unusual appearance.
Close inspection revealed tiny white hairs growing on the upper surfaces
of all the leaves, especially the youngest leaves. From a distance the
new leaves looked as if they had a coating of white dust or flour over
them! Locals gave the vine a nickname “the dusty miller’ as
it reminded them of mill workers after a long day milling flour.
Although
the vine’s leaf color and appearance were unlike the Pinot Noir vines of
France or Germany, the fruit clusters were similar to the Pinot Noir grapes of
those famous regions. The vine most resembled Pinot Meunier of the Champagne region
in France, which itself is a natural mutation of Pinot Noir. However, Wrotham
Pinot differed from Pinot Meunier in that the Wrotham vine had somehow developed
a considerable immunity to the powdery mildew disease that affects all other Vitis
vinifera vines now cultivated around the world.
English
viticulture scholars eventually came to the conclusion the Wrotham vine was a
natural seedling of Pinot Noir vines that the early Romans brought to England
2000 years ago!
The village of Wrotham has a long history of Roman influence. The Wrotham
Historical Society has records and artifacts that show the area was populated
for many centuries by Romans and their descendants. Even in recent times,
residents digging in gardens or in construction projects have discovered
occasional Roman coins dating from the third century AD. 
English winemakers took cuttings from this wild Wrotham vine to propagate
a small vineyard as a test for commercial winemaking in England. Because
today’s cooler English climate is reminiscent of the Champagne district
of France, local winemakers experimented with the Wrotham fruit to make
sparkling “Blanc de Noir” wines.
These exceptional sparkling wines did not go unnoticed. California winemaker
Dr. Richard Grant Peterson liked the sparkling wine so much he imported Wrotham
cuttings to California in 1980. After a quarantine of many years as required by
law, he patiently and meticulously began propagating new vines from this bud wood
to develop two full acres of Wrotham Pinot vines in Napa Valley.
These vines were analyzed at the University of California, Davis, which
reported that Wrotham Pinot DNA is identical to that of Pinot Noir.
The
English scholars were right! Wrotham Pinot vines are antiques; the final
offspring of many natural generations from the original Roman Pinot Noir
vines grown in England many, many years ago. It seems likely the variety’s
development of natural resistance to vine diseases was a factor in the
Wrotham vines’ ability to survive two millennia of English weather.
It
was a fortunate discovery that none of our Wrotham grapevines in the Napa
Valley has ever needed to be dusted with sulfur to protect against Powdery
mildew -- as happens routinely with all the other commercial vines in
California and most of the world. Since no chemical fungicides or insecticides
are used on these vines, the vineyard qualifies as organic.
