Chelois, or Seibel 10878, is one of the group of grapes known as hybrid grapes. These are grapes which were created by breeding American grapevines and French grapevines together to create a hearty grape with a combination of good flavor and winter-sturdiness.
Chelois was first produced by Albert Seibel who developed a huge number of grape styles in the 1950s.
Chelois is found to make a fairly tasty wine, but can be challenging to grow. Even with its relatively good flavor, Chelois is primarily used as a neutral blending wine.
