History

In the early 19th century, Roublot made up a third of the area in Saint-Bris-le-Vineux in the west of Chablis. Then the vines were wiped out in the phylloxera epidemic, and uniquely for Burgundy, were replaced by Sauvignon blanc, the wines of which today are designated Saint-Bris AOC.

DNA fingerprinting has shown that Roublot is one of many grapes to be the result of a cross between Gouais blanc (Heunisch) and Pinot, making it a full sibling of famous varieties such as Chardonnay and Aligoté. Gouais blanc was widely grown by the French peasantry in the Medieval ages. This offered lots of opportunities for hybridization, and the offspring benefited from hybrid vigor as the parents were genetically quite different.

Other Gouais blanc/Pinot crosses include Aubin vert, Auxerrois, Bachet noir, Beaunoir, Franc Noir de la Haute-Saône, Gamay Blanc Gloriod, Gamay, Melon, Knipperlé, Peurion, Romorantin, Roublot, and Sacy.

The synonym César blanc may reflect a traditional link with the ancient red grape César, a Pinot/Argant cross.

Viticulture

Like many Pinot/Gouais crosses, Roublot is quite vigorous, with small bunches. It is a very unreliable yielder, thanks to its high susceptibility to powdery mildew and grey rot.

Wine regions

Roublot has just about disappeared from commercial production.

gollark: Sophonts are defined as nondeterministic in some way, right? Presumably you could, though, force them to make a particular decision by making it the only consistent one. Or does the universe just proactively not allow that kind of situation?
gollark: Vaguely relatedly, how do the self-consistency things interact with the universe's enforced free will?
gollark: The simplest self-consistent result of any form of time travel existing is that you just never use it ever.
